Aim: To evaluate the relationship between liver metastasis volume and survival in colorectal cancer patients using the volumetric measurement method.Methods: 114 colorectal cancer patients with isolated liver metastases were included in the study. Liver tumor volume, total liver volume were calculated from the patients images at the time of diagnosis. Vitrea 7.14 imaging software was used for liver volume analysis and volume analysis of each metastasis.Results: Median overall survival(OS) in the group with tumor volume <42 ml³ was 30.98 months In the group with tumor volume ≥42 ml³, median OS was 16.36 months (p: 0.001). In patients who underwent metastasectomy, the median OS in the group with a tumor volume <42 ml³ was 52.3 months, the median OS in the group with a tumor volume ≥42 ml³ was 22.2 months. In patients who did not undergo metastasectomy, the median OS in the <42 ml³ group was 20.23 months, the median OS in the ≥42 ml³ group was 15.63 months.Conclusion: In our study, we found that liver metastasis volume was prognostic for OS. It is argued that tumor volume measurement by volumetric measurement is a widely used method in the decision for metastasectomy in liver metastatic colorectal cancer patients.

Aim: The effect of skeletal muscle mass and density on the long-term survival outcome of breast cancer patients is unclear.Materials & methods: Systematically searched all articles in PubMed, Web of science, Springerlink, EMBASE and Wiley databases that studied the association between skeletal muscle and survival outcomes of breast cancer by 25 September 2023. The hazard ratios and confidence intervals of the multiple factor analysis results controlling for confounding variables in the study were collected and analyzed using STATA 14.0 software.Results: This meta-analysis included a total of 13 studies, with a median age of 48.2 years. Meta results showed that the survival (hazard ratio [HR]: 0.98, 95% CI: 0.89-1.08) and recurrence (HR: 0.96, 95% CI: 0.92-1.00) outcomes of breast cancer patients with sarcopenia were not significantly affected compared with those without sarcopenia. No significant heterogeneity or publication bias was observed in the study.Conclusion: The conclusion that skeletal muscle is regarded as a useful factor that can guide and optimize the prognosis of breast cancer patients is uncertain, or the result is very weak. Considering the impact of research quality and confounding factors, prospective studies are needed in the future to further demonstrate.PROSPERO identifier: CRD42023463480 (www.crd.york.ac.uk/prospero).

Antibody-drug conjugates (ADCs) have recently emerged as a promising therapeutic option that combine the specificity of monoclonal antibodies and the cytotoxic effect of chemotherapy. With numerous ADCs approved and on the market, a particular concern of ADCs that target HER-2 has been their cardiac side effects, in view of the crucial role of HER-2 in cardiac development and physiology. While rarely toxic and generally safe, numerous publications have outlined the consistent association of trastuzumab emtansine (T-DM1) and trastuzumab deruxtecan (T-DXd) with the development of cardiac toxicity. Despite not being clinically relevant in most cases, cardiac baseline evaluation, monitoring and early detection of cardiac adverse events remain pivotal with HER-2 targeting ADCs. This review aims to summarize and better characterize the complete cardiac toxicity profile of HER-2 ADCs, with the goal of improving clinical understanding of this adverse event, leading to better recognition, monitoring and management.

Aim: This study aimed to investigate the risk factors for lymph node metastasis in 1-3 cm adenocarcinoma and develop a new nomogram to predict the probability of lymph node metastasis.Materials & methods: This study collected clinical data from 1656 patients for risk factor analysis and an additional 500 patients for external validation. The logistic regression analyses were employed for risk factor analysis. The least absolute shrinkage and selection operator regression was used to select variables, and important variables were used to construct the nomogram and an online calculator.Results: The nomogram for predicting lymph node metastasis comprises six variables: tumor size (mediastinal window), consolidation tumor ratio, tumor location, lymphadenopathy, preoperative serum carcinoembryonic antigen level and pathological grade. According to the predicted results, the risk of lymph node metastasis was divided into low-risk group and high-risk group. We confirmed the exceptional clinical efficacy of the model through multiple evaluation methods.Conclusion: The importance of intraoperative frozen section is increasing. We discussed the risk factors for lymph node metastasis and developed a nomogram to predict the probability of lymph node metastasis in 1-3 cm adenocarcinomas, which can guide lymph node resection strategies during surgery.

What is this study about?: This is a summary of the results of an ongoing study called CROWN. In the CROWN study, researchers looked at the effects of two medicines called lorlatinib (Lorbrena) and crizotinib (Xalkori) for people with advanced non-small cell lung cancer (NSCLC) who had not been treated yet. Everyone in the study had changes in a gene called anaplastic lymphoma kinase, or ALK, in their cancer cells. The changes in the ALK gene can make cancer grow. This analysis looked at how well lorlatinib and crizotinib worked and their side effects in people with advanced ALK-positive NSCLC after 5 years.

What did this study find?: After observing people for an average of 5 years, researchers found that more people who took lorlatinib were still alive without their cancer getting worse than the people who took crizotinib. At 5 years, the probability of being alive without their cancer getting worse was 60% in people who took lorlatinib compared with 8% in people who took crizotinib. Fewer people who took lorlatinib had their cancer spread within or to the brain than the people who took crizotinib. In more than half of the people who took lorlatinib, tumors that had spread to the brain did not get worse, and no new tumors spread to the brain after 5 years. In contrast, in about half of the people who took crizotinib, tumors that had spread to the brain got worse or new tumors spread to the brain after 16.4 months. More people who took lorlatinib (115 out of 149, or 77%) had severe or life-threatening side effects than people who took crizotinib (81 out of 142, or 57%). These side effects were like the ones reported in the earlier 3-year analysis.

What do the findings of the study mean?: The 5-year results from the CROWN study showed that more people who took lorlatinib continued to benefit from their treatment than those who took crizotinib. The 5-year benefit of lorlatinib in people with ALK-positive NSCLC has never been seen before.Clinical Trial Registration: NCT03052608 (Phase 3 CROWN study) (ClinicalTrials.gov).

What is this summary about?: This is a summary of an article describing the main results of the MAJIC-PV study. This study looked at using the cancer drug ruxolitinib to treat a type of blood cancer called polycythemia vera. People with polycythemia vera make too many red blood cells in their body. This can make their blood thicker and can increase the chances of blood clots forming in their blood vessels.Researchers wanted to find out how well ruxolitinib worked compared with the best available therapy as a treatment for people with polycythemia vera who were at risk of developing blood clots that could lead to a heart attack or stroke. Specifically, the study looked at people who had already taken the chemotherapy hydroxycarbamide (also known as hydroxyurea) for their polycythemia vera, but it either didn't work for them or gave them side effects that they could not tolerate.

What were the results?: In the study, researchers divided 180 adults with polycythemia vera who were at high risk of developing blood clots that could lead to a stroke into two groups: 93 people who took ruxolitinib twice a day, and 87 people who took the best available therapy. 43% of people who took ruxolitinib and 26% of people who had the best available therapy had normal blood counts and spleen size within 1 year of treatment. 84% of people who took ruxolitinib and 75% of people who had the best available therapy lived for at least 3 years without their polycythemia vera becoming a more advanced type of blood cancer. The most common side effects were disorders of the digestive system (stomach and gut), disorders of the blood vessels, and infections. This is similar to the side effects that doctors know about for ruxolitinib.

What do the results mean?: Compared with people who had the best available therapy for their polycythemia vera, people who took ruxolitinib were more likely to have normal blood counts and spleen size within 1 year of treatment, and were more likely to live longer without their polycythemia vera becoming a more advanced type of blood cancer.

Aim: First-line (1L) immunotherapy has yielded superior overall survival (OS) in metastatic melanoma (MM) but some patients are ineligible for immunotherapy or need rapid response with 1L targeted therapy (TT).Materials & methods: Retrospective cohort study of real-world patients treated with 1L immunotherapy (144 BRAF wild type, 85 BRAF-mutated) or 1L TT (143 BRAF-mutated) for MM in Finland during 2014-2021.Results: Baseline brain metastases, liver metastases and elevated LDH were less common, 2-year OS rates were higher (60.3-63.5% vs. 33.8%) and more patients were alive without the next-line treatment (38.0-43.8% vs. 23.3%) in patients with 1L immunotherapy.Conclusion: Real-world patients with 1L immunotherapy for MM had favorable baseline characteristics and better treatment outcomes than observed in patients with 1L TT.
