Previously we reported that immunological changes after Atezo/Bev administration for unresectable hepatocellular carcinoma (uHCC) revealed significant alterations in interleukin (IL)-6, soluble IL-2 receptor, tumor necrosis factor-alpha, and programmed cell death-1 levels. Among these variable factors, serum levels of IL-6 can be easily measured on a commercial baias. Therefore, this study aimed to investigate the utility of serum IL-6 as a predictor of tumor response to Atezo/Bev treatment for uHCC.METHODSThe study included 44 patients with HCC treated with Atezo/Bev. Blood samples were collected before and 3 weeks after treatment, and tumor response was assessed using contrast-enhanced computed tomography 6 weeks after treatment.RESULTSSignificant changes in serum IL-6 levels were observed in patients treated with Atezo/Bev as first-line therapy but not in those treated with it as second line or later-line therapy. In patients treated with Atezo/Bev as first-line therapy, serum IL-6 levels increased significantly after treatment in patients with a complete or partial response but not in patients with stable or progressive disease. Furthermore, compared to other tumor markers such as alpha-fetoprotein, lens culinaris agglutinin-reactive fraction of alpha-fetoprotein, and des-gamma-carboxyprothrombin, serum IL-6 levels exhibited the highest sensitivity in predicting tumor response during the treatment period.CONCLUSIONIn patients with uHCC treated with Atezo/Bev, serum IL-6 levels could serve as a potential predictor of tumor response. Elevated levels after treatment may indicate a favorable tumor response and prognosis.","PeriodicalId":19497,"journal":{"name":"Oncology","volume":"43 1","pages":"1-24"},"PeriodicalIF":3.5,"publicationDate":"2024-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142255258","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods We conducted a multi-institutional retrospective study of 90 gastric cancer patients who previously received anti-PD-1 therapy (nivolumab). On computed tomography images captured before nivolumab induction, the skeletal muscle index (SMI, cm2/m2) was defined as the erector muscle area (cm2) divided by the height (m) squared. Patients were divided into two groups: those with SMI-high (n = 45) and those with SMI-low (n = 45). Prognostic nutritional index (PNI) was also calculated before nivolumab induction. The associations of SMI and PNI with response rate (RR), progression-free survival (PFS), overall survival (OS), disease control rate (DCR), and safety were analyzed. Results The cutoff values for SMI were determined as 13.45 for males and 10.41 for females. SMI-high was significantly associated with a higher RR (odds ratio = 12.36, p = 0.02) and DCR (odds ratio = 2.97, p = 0.02). Although not significant, PNI-high also tended to be associated with a higher RR. Multivariate analysis showed that SMI-high was independently associated with a higher RR and higher DCR in gastric cancer. Moreover, prognostic analyses revealed that SMI-high (log-rank test p = 0.008) and PNI-high (log-rank test p = 0.0008) were significantly associated with longer OS since nivolumab induction. SMI-high was also associated with longer PFS (log-rank test p = 0.03). There were no significant differences in irAE between SMI-low and SMI-high. Conclusions SMI and PNI were associated with nivolumab efficacy in gastric cancer patients.

Culturally and linguistically diverse (CALD) or socially disadvantaged patients have notably lower rates of participation in these trials. We aimed to characterise the social and cultural demographics of patients enrolled on an EPCT in South Western Sydney. Methods We conducted a 10-year retrospective review of patients enrolled on a EPCT at Liverpool Hospital. CALD patients were defined as those born overseas or whose preferred language was other than English. The patient residential address was used to calculate distance travelled and the Index of Relative Socio-economic advantage and disadvantage (IRSD and IRSAD) scores were calculated and used as a surrogate for socioeconomic status (SES). Results Our study included 233 patients across 39 EPCTs. Ninety-one patients (39%) were identified as CALD. The median IRSD and IRSAD scores were 941 and 944 respectively with 62.7% - 67.4% of patients residing in an area with greater disadvantage compared to the median of Australia. The median distance travelled was 17 kilometres with only 12% of participants travelling more than 50 kilometres. CALD patients were more likely to reside in an area of low SES (OR 3.4, 95% CI 1.8 - 6.5, p&lt;0.01) and travelled shorter median distances (10 vs 23 kilometres) when compared to non-CALD patients. Conclusion Our study cohort contained a lower proportion of CALD patients and a higher SES than what we might have expected from our local population. Furthermore, there was a trend toward greater SES disadvantage (lower IRSD/IRSAD scores) for the CALD population. This study provides novel Australian data to support the underrepresentation of culturally diverse or disadvantaged patients on EPCTs.

This makes neoadjuvant chemotherapy (NAC) a valuable option for treating both early and advanced stages of the disease. The tumor's response to HER2-targeted NAC provides crucial prognostic information. Additionally, it allows for tailoring adjuvant treatment strategies for HER2+ breast cancer based on pathological responses. This study aimed to investigate the clinicopathological factors that influence tumor response. Methods We retrospectively analyzed 122 patients diagnosed with HER2+ breast cancer. These patients received NAC and HER2-directed therapy between January 2018 and December 2022 at the Pusan National University Yangsan Hospital. Following surgery, tumor response was evaluated, categorizing patients into two groups: pathological complete response (pCR) and non-pCR groups. We analyzed data on various factors, including age, NAC regimen, type of breast and axillary surgery, clinical stage (cTNM), historical grade, and pre-operative levels of carcinoembryonic antigen, cancer antigen 15-3 (CA 15-3), estrogen receptor (ER), progesterone receptor (PR), HER2, p53, and KI-67. Results Out of the 122 patients, 75 achieved pCR, while 47 did not. Most clinicopathological factors showed no significant difference between the pCR and non-pCR groups. However, several factors were associated with a higher pCR rate: normal preoperative CA 15-3 levels (odds ratio [OR]: 3.74, confidence interval [CI]: 1.19-11.72, P = 0.02), preoperative-ER positivity (OR: 2.65, CI: 1.25-5.59, P = 0.01), PR negativity (OR: 3.92, CI: 1.82-8.45, P &lt;0.05), and strong preoperative HER2 immunohistochemistry (IHC) 3+ staining. Multivariate analysis confirmed that PR negativity (OR: 2.8, CI: 1.23-6.42, P = 0.01) and strong preoperative-HER2 IHC 3+ staining (OR: 0.18, CI: 0.03-0.84, P = 0.04) were independent predictors of a higher pCR rate. Conclusions A pCR after NAC impacts patient prognosis and influences the choice of adjuvant treatment for HER2+ breast cancer. Clinicopathological factors can help predict responses to HER2-targeted NAC. In our study, pre-ER/PR negativity, high pre-HER2 levels, and normal CA 15-3 levels were found to be potential predictors of pCR. These findings may contribute to developing more effective treatment strategies for HER2+ breast cancer.","PeriodicalId":19497,"journal":{"name":"Oncology","volume":"34 1","pages":"1-16"},"PeriodicalIF":3.5,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142222948","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
