Efficacy of chemotherapy for patients with gastric cancer with early recurrence during or after adjuvant chemotherapy with S-1 alone: a multicenter retrospective study

This study aimed to survey the efficacy of chemotherapy regimens in the real world setting and explore the most promising regimen for patients experiencing early recurrence for gastric cancer. We retrospectively reviewed the clinical course of 207 patients with gastric cancer, who developed early recurrence during or within 6 months after completing S-1 adjuvant therapy at 19 Japanese institutions between 2012 and 2016. The treatment regimens after recurrence were fluoropyrimidines plus platinum-based regimens (FP) in 91 (44%) patients, paclitaxel-based regimens (PTX) in 102 (49%), and irinotecan-based regimens (IRI) in 14 (7%). The overall response and disease control rates were 28.7% and 54.1%. Median progression-free survival (PFS) and overall survival (OS) were 5.1 and 12.9 months, respectively. In the FP, PTX, and IRI regimens, the median PFS and OS were 5.9, 4.1, 4.1 months and 12.8, 12.9, and 11.8 months, respectively. The combination of PTX and ramucirumab showed survival comparable to capecitabine plus platinum. Multivariate analyses for OS showed that recurrence during adjuvant chemotherapy and undifferentiated histological type were independent poor prognostic factors. Although the prognosis of patients with early recurrence even with adjuvant S-1 was poor, PTX plus ramucirumab therapy could be a potential treatment option.

Prognostic impact of DTA mutation and co-occurring mutations in patients with myelodysplastic syndrome.

To evaluate the frequency and prognostic significance of DTA (DNMT3A、TET2、ASXL1) gene mutation and co-occurring mutations in patients with myelodysplastic syndrome (MDS). The clinical data of 102 newly diagnosed MDS patients who accepted Next Generation Sequencing (NGS) was retrospectively analyzed. According to whether the patients had DTA gene mutation, the patients were divided into DTA mutated (DTA-mut) group and wild type (DTA-wt) group, and the relationship between gene mutation and clinical characteristics and prognosis was analyzed. Among the 102 MDS patients, 96% (98/102) presented with mutation, while the mean number of mutations was 3.04 mutations/patient. DTA-mut was detected in 56.9% (58/102) patients. The most frequent co-mutated genes in DTA-mut group were SF3B1 (25.8%), RUNX1 (24.1%), U2AF1 (18.9%), SRSF2, EZH2, SETBP1 (17.2%), STAG2 (15.5%), IDH2 (12.1%) and BCOR, CBL (10.3%). The two groups showed no significant differences in ages, blood parameters, bone marrow blasts, WHO 2022 classification, IPSS-R risk category and rate of conversion to leukemia. Compared with the DTA-wt group, the mutation frequency of RUNX1 was higher (P = 0.02), while mutation frequency of TP53 was lower (P = 0.001) and the mutation frequency of ≥ 3 co-mutated genes was higher in DTA-mut group (P = 0.00). Survival analysis showed that the overall survivals (OS) of DTA-mut patients was significantly inferior to that of DTA-wt patients (P = 0.0332). According to IPSS-R classification, a statistically significant difference in OS was only observed in higher risk (IPSS-R > 3.5) group (P = 0.0058). In the context of DTA mutation, the OS of patients with RUNX1 mutation was shorter than that of patients without RUNX1 mutation significantly (P = 0.0074). The OS of patients with SF3B1 mutation was longer than that of patients without SF3B1 mutation, but there was no statistical difference (P = 0.0827). DTA mutations were not independent prognostic factors when DTA and co-mutated genes with frequency > 10% were considered in Cox regression model (P = 0.329). However, multivariate analysis confirmed an independently adverse prognosis of RUNX1 co-mutation (P = 0.042, HR = 2.426, 95% CI:1.031-5.711) in DTA-mut cohort. Moreover, our multivariable analysis suggests that SRSF2-mutwas an independent poor prognostic factor for all MDS patients (P = 0.047), but lost significance (P = 0.103) for DTA-mut patients. DTA mutations are frequently observed in patients with MDS, often accompanied by genes involved in RNA splicing and transcription factors like SF3B1 and RUNX1. DTA and concomitant mutations affect prognosis in MDS patients and RUNX1 was identified as an independent poor prognostic factor in patients with DTA mutations.

Chromosome 1q21 Aberrations Are Poor Prognostic Factors for Newly Diagnosed Multiple Myeloma Patients.

Chromosome 1q21 aberrations are one of the most common cytogenetic abnormalities in patients with multiple myeloma (MM). However, the prognostic value remains controversial. This study aimed to determine the prognostic value of numerical abnormalities of chromosome 1q21 for newly diagnosed patients with MM patients in Chinese population. We retrospectively analyzed 629 patients with newly diagnosed MM who received the detection of chromosome 1q21 by fluorescence insitu hybridization in China. Among 629 patients, 309 (49.1%) had 1q21 abnormalities, of which 187 (29.7%) had three copies and 122 (19.4%) had four or more copies. Patients with two copies of 1q21 had a significantly longer median overall survival (OS) than those with three copies or ≥4 copies and also had longer progression-free survival (PFS). However, patients with three or ≥4 copies had similar OS and PFS. Univariate Cox proportional hazards regression analyses determined that 1q21 aberrations are associated with shorter OS and PFS. 1q21 aberrations are also independent poor prognostic factors for OS and PFS in multivariable analyses. Del(17p), t(4;14), and t(14;16) are common high-risk cytogenetic abnormalities (HRCAs) in patients with MM. Patients with 1q21+ alone or 1q21+ combined with HRCAs had shorter OS and PFS than patients without cytogenetic abnormalities. Patients with 1q21+ and t(11;14) also had shorter PFS but had similar OS than patients without cytogenetic abnormalities. Our study showed that chromosome 1q21 aberrations are poor prognostic factors for newly diagnosed patients with MM.

Features and prognostic significance of soluble TIM-3 and its ligands Gal-9 and CEACAM1 levels in the diagnostic bone marrows of adult acute myeloid leukemia patients.

Prognostic significance of soluble immune checkpoint molecule TIM-3 and its ligands in the plasma has been illustrated in various solid tumors, but such study in newly diagnosed acute myeloid leukemia (AML) remains absent. Soluble TIM-3, Gal-9 and CEACAM1 levels in the bone marrow plasma samples collected from 90 adult AML patients at diagnosis and 12 healthy donors were measured by enzyme-linked immunosorbent assays (ELISA), and 16 AML patients were simultaneously tested cell membrane TIM-3 expression by multi-color flow cytometry. AML patients had significantly elevated soluble TIM-3 levels and similar soluble Gal-9 and CEACAM1 levels compared with healthy donors (p = 0.0003, 0.26 and 0.96). In the whole cohort, high soluble TIM-3 level was the sole independent adverse prognostic factor for relapse-free survival (RFS) (p = 0.0060), and it together with adverse ELN genetic risk were independent poor prognostic factors for event-free survival (EFS) (p = 0.0030 and 0.0040); High soluble CEACAM1 level were significantly related to lower RFS (p = 0.028). In addition, high soluble Gal-9 level had significant association with lower RFS in patients receiving allogeneic hematopoietic stem cell transplantation (allo-HSCT) at the first complete remission (p = 0.037). Furthermore, soluble TIM-3 level tended to have positive correlation with the percentage of non-blast myeloid TIM-3+ cells in nucleated cells in AML (r = 0.48, p = 0.073). Therefore, the high soluble TIM-3 level in the diagnostic BM plasma predicted poor outcome in adult AML patients, and high sGal-9 level was associated with relapse after allo-HSCT.

FP3.4 - Identifying missed opportunities in emergency presentations of colorectal cancer to improve patient outcomes

Abstract Introduction and Aim A significant proportion of patients diagnosed with colorectal cancer are diagnosed during emergency admissions with presentations such as bowel obstruction, perforation and bleeding. Despite increasing numbers of suspected colorectal cancers referrals from the community being sent straight to test, the proportion of patients presenting as emergencies in the United Kingdom remains at20%. Emergency presentations of colorectal cancer are associated with significantly worse outcomes – both short- and long-term, with research suggestive that emergency presentations remain an independent poor prognostic factor following curative colorectal resection. This study aims to assess if patients diagnosed with colorectal cancer following emergency presentation had missed opportunities of diagnosis on previous presentations in secondary care. Methods A database of patients who have been diagnosed with colorectal cancer following emergency presentation from January2020-October2023 was analysed. Previous attendances to the emergency department and outpatient department were identified and assessed for symptoms of colorectal cancer – including abdominal pain, change in bowel habits, rectal bleeding and iron deficiency anaemia – and if these prompted investigation. Results Of 100 patients – 6were identified that had previous presentations with symptoms suggestive of colorectal malignancy. 2 had been reviewed in colorectal clinic prior to their diagnosis, with appropriate planned investigations but were lost to follow up. A further 4 had been seen in ED with symptoms of colorectal cancer but further investigations were not performed. Conclusion The majority of patients diagnosed with colorectal malignancy following emergency presentation had no earlier opportunities of diagnosis in secondary care. Further work needs to be done ensuring the continuity of care of patients following discharge from both the emergency department and clinic.

Number of positive lymph nodes and lymph node ratio predict recurrence and survival in hypopharyngeal cancer based on SEER database and validation of real-world data.

This study investigated the impacts of the number of positive lymph nodes (NPLN) and lymph node ratio (LN ratio) for patients with hypopharyngeal squamous cell carcinoma (HPSCC) based on SEER database, which were validated in the real-world data of China. A total of 520 patients from SEER database were analyzed. Then 195 patients with pathologically stage III or IV HPSCC in our center were retrospectively studied. In the SEER database, NPLN ≥ 3 was found in 36.9% of patients. Multivariate analysis revealed that LN ratio ≥ 0.138 was significant with poorer overall survival (OS) (hazard ratio [HR] = 1.525, p = 0.001) and cancer-specific survival (CSS) (HR = 1.697, p < 0.001), so was the NPLN ≥ 3 (HR = 1.388, p = 0.013; HR = 1.479, p = 0.008). Patients with NPLN ≥ 3 were found in 103 (52.8%) in our center. Multivariate analysis confirmed a significant association regarding OS (p = 0.005) or CSS (p = 0.003) between patients with LN ratio ≥ 0.138 or not. In addition, disease recurrence rate differed significantly between the patients with NPLN ≥ 3 (27.2%) and NPLN < 3 (14.1%, p = 0.026). Moreover, postoperative chemoradiotherapy (CCRT) was significantly associated with better prognosis in patients with NPLN ≥ 3. In the SEER database, NPLN ≥ 3 and LN ratio ≥ 0.138 were independent poor prognostic factors for patients with HPSCC. Whereas identifying worldwide cut-off values for LN ratio is difficult and surgeon-dependent. In our cohort, adjuvant CCRT was beneficial for OS in patients with NPLN ≥ 3.

Evaluation of Five Screening Tools in Detecting Physical Frailty in Cirrhosis and Their Prognostic Role.

Background: Physical frailty (PF) is a syndrome of decreased physical function and reserves, preventing patients from coping with stressful events. PF screening tools in patients with liver cirrhosis (LC) can help evaluate the risk of complications and death. The aim of this study was to assess the performance of five screening tools in detecting PF and their ability to predict 18-month mortality in LC. Methods: The Short Physical Performance Battery (SPPB), Fried frailty phenotype (FFP), Clinical Frailty Scale (CFS) and 6-Minute Walk Test (6MWT) were compared with the Liver Frailty Index (LFI) as the method of reference. Patients with an LFI ≥ 4.5, SPPB ≤ 8, FFP ≥ 3, CFS ≥ 6 points, and those walking <250 m, were considered frail. Results: A total of 109 consecutive patients with stable LC were included [63.3% male, median age 62 years, (IQR 52-70), MELD 9 (7-14.5), 46.8% with decompensated LC (DC)]. PF was present in 23.9%, 27.5%, 41.3%, 13.8%, and 28.4% as assessed by the LFI, SPPB, FFP, CFS, and 6MWT, respectively. Cohen's kappa measurement of agreement of four of the tools with LFI was 0.568, 0.334, 0.439, and 0.502, respectively (p < 0.001 for each). Kaplan-Meier survival curves at 18 months showed higher mortality in frail patients compared to non-frail patients by any method (log rank p < 0.05). In the multivariate models, PF defined by any method emerged as an independent prognostic factor of 18-month mortality after adjustment for age, gender, and MELD-score. Conclusions: Patients characterized as frail by five screening tools were not identical. However, PF defined by either method was proven to be an independent poor prognostic factor for long-term mortality after adjustment for covariates.

Major pathologic response and long-term clinical benefit in hormone receptor-positive, human epidermal growth factor receptor 2-negative breast cancer after neoadjuvant chemotherapy

BackgroundThe majority of HR+/HER2-breast cancer patients can also achieve long-term survival despite not attaining pCR, indicating limited prognostic value of pCR in this population. This study aimed to identify novel pathologic end points for predicting long-term outcomes in HR+/HER2-breast cancer after neoadjuvant chemotherapy. MethodsWe analyzed HR+/HER2-breast cancer patients with stage II-III tumors who underwent curative surgery after neoadjuvant chemotherapy from three hospitals. Major pathologic response (MPR), defined as the presence of Miller-Payne grades 3–5 and positive lymph node ratio of ≤10 %, was used as a pathological evaluation indicator. We assessed the association between MPR and event-free survival (EFS) and performed Multivariable Cox regression to identify independent factors associated with EFS. ResultsFrom January 2010 to December 2020, 386 patients were included in the final analysis. 28 patients (7.3 %) achieved pCR and 118 patients (30.6 %) achieved MPR. The median duration of follow-up was 54.4 months,5-year EFS was 87 % in the MPR group vs. 68 % in the non-MPR group. Multivariate analysis showed that low PR expression, high clinical stage, lower Miller–Payne grades and Positive lymph node ratio were independent poor prognostic factors for EFS (all P values < 0.05). The prognostic effect of MPR remained in multivariable models (hazard ratio (HR), 0.45; 95 % confidence interval (CI), 0.26–0.76; P = 0.008), In non-pCR patients, those who achieved MPR exhibited a similar EFS compared with pCR patients (HR, 2.25; 95 % CI, 0.51–9.84; P = 0.28). ConclusionMPR may be a novel pathologic end point in HR+/HER2-breast cancer after neoadjuvant chemotherapy, holding greater applicability in the prognosis evaluation than pCR.

Prognostic Impact of Human Lymphocyte Antigen (HLA) Class I Expression in Patients With Breast Cancer.

Various biomarkers are utilized in the field of breast cancer. Human lymphocyte antigen (HLA) class I molecules have a critical role in cancer immune surveillance. Therefore, this study aimed to assess the HLA class I expression and analyze the correlation with clinicopathologic factors in breast cancer. We investigated the clinical pathology archives of 150 consecutive patients with breast cancer who underwent a curative operation at the Sapporo Medical University, Japan, from January 2012 to December 2014. Immunohistochemical staining was used to evaluate HLA class I expression and CD8-positive T cell infiltration. The Pearson χ2 test was used to assess HLA class I expression level and clinicopathological parameters. The Kaplan-Meier method was used to evaluate survival and the log-rank test to analyze the differences between survival curves. Patients with dull/negative HLA class I had significantly poor disease-free survival (DFS) compared with those with positive HLA class I (p=0.0073). Univariate analyses revealed that pT, pN, positive lymphatic invasion, and dull/negative HLA class I were significantly associated with DFS. Multivariate analyses revealed dull/negative HLA class I as an independent poor prognostic factor (hazard ratio=2.75, 95% confidence interval=1.30-5.80, p=0.008). HLA class I expression level may have a very sensitive prognostic effect on patients with breast cancer.

The Association of Transferrin Receptor with Prognosis and Biologic Role in Intrahepatic Cholangiocarcinoma.

Ferroptosis is a cell death caused by iron-dependent accumulation of lipid peroxidation. Transferrin receptor (TFR) is a ferroptosis-related protein responsible for iron transport. The detailed biologic role of TFR in intrahepatic cholangiocarcinoma (ICC) is not fully elucidated. The study enrolled 92 ICC patients who had undergone hepatic resection. Immunohistochemistry (IHC) assays were performed for TFR protein expression. The regulation of malignant activity and the effect on sensitivity to the ferroptosis-inducer artesunate by TFR were investigated in vitro. Using IHC staining, 23 patients were categorized as TFR-positive. The TFR-positive group had a significantly larger tumor size and more microscopic vascular invasion. In the multivariate analysis, TFR positivity was an independent poor prognostic factor. In vitro TFR-knockdown (KD) significantly decreased the intracellular iron levels and the cell proliferation, migration, and invasion rates. Artesunate treatment significantly decreased cell viability, whereas cisplatin promoted ferroptosis. When iron transport into cells was inhibited by TFR-KD, ferroptosis was significantly suppressed. Expression of PD-L1 was induced by cisplatin, with a further increase observed when artesunate and cisplatin were used in combination. Transferrin receptor is a poor prognostic factor for ICC and contributes to sensitivity to ferroptosis.

Pustular mycosis fungoides has a poor outcome: a multicentric clinico-pathological and molecular case series study.

Mycosis fungoides (MF) has usually an indolent course. However, some patients develop a more aggressive disease and few prognostic parameters have been identified. Isolated cases of pustular MF (pMF) suggest an unfavourable prognosis. We aim to describe the clinico-pathological characteristics and prognostic value of pMF. We retrospectively collected data of all cases of MF with histological pustules diagnosed from 2009 to 2020. The outcomes and clinico-pathological characteristics of pMF at diagnosis (pMFD) were compared to those of a cohort of non-pustular MF (NpMF). 33 pMF (including 22 pMFD) and 86 NpMF cases were included. The median age at diagnosis of pMF was 61 years [IQR=50-75]. The median follow-up of pMFD was 32 months [IQR=14-49]. Clinically, 33% of pMF had pustules. Large-cell transformation (LCT) occurred in 17 cases. pMFD were at a significantly more advanced-stage and more showed LCT at diagnosis than NpMF (50% vs 7%, p<0.001 and 23% vs 0%, p<0.001, respectively). In multivariate Cox analysis, the presence of histological pustule at diagnostic was associated with shorter OS in all patients (HR=13.90, CI95%[2.43-79]; p=0.003), and in early-stage patients (HR=11.09, CI95%[1.56-78.82]; p=0.02). In multivariate Fine and Gray model analysis, pMFD was associated with a higher cumulative incidence of LCT (SHR=13.90, CI95% [2.43-79]; p=0.003) in all patients. Median OS after the occurrence of histological pustules during follow-up of all pMF patients was 37 months, with a five-year OS of 25% (CI95% [0.06-0.5]). pMF often follows an aggressive course, with a high risk of LCT and shorter survival, even for early-stage patients. Histological pustules at diagnostic of MF might represent an independent poor prognostic factor, to be confirmed by further studies. Because pustules are not always clinically identified, histological pustules should be mentioned in pathology reports of MF and prompt discussion of a closer follow-up.

Association of aberrant expression of CD39 with the outcome of patients with cholangiocarcinoma.

93 Background: Cholangiocarcinoma is defined as a kind of malignant tumor originating from bile ducts. Due to the lack of effective diagnostic and treatment methods, the prognosis of cholangiocarcinoma is dismal. Accumulating evidence indicates that CD39 could promote the progression of several types of cancer. However, the biological function and the underlying mechanism of CD39 in cholangiocarcinoma have not been well investigated. Methods: Quantitative reverse transcription PCR (RT-qPCR), western blot (WB), and immunohistochemistry staining was used to evaluate the expression level of CD39 in cholangiocarcinoma. Kaplan-Meier and Cox hazard ratio regression analyses were implicated to evaluate the prognostic significance of CD39. Cell counting kit-8 (CCK-8) was carried out to evaluate the proliferative capacity, while transwell assay was used to detect the migration and invasion ability. In addition, B-NDG mice were used for the in vivo assay. The potential protein binding with the CD39 was identified through co-immunoprecipitation. Results: We observed that CD39 was aberrantly expressed in the tumor tissue and cholangiocarcinoma cell lines. Our analysis indicated that the high expression level of CD39 correlated with aggressive clinicopathological characteristics, and CD39 was identified as an independent poor prognostic factor in cholangiocarcinoma. In addition, our in vitro and in vivo data indicated that the knockdown of CD39 could suppress the proliferation, migration, invasion ability, and the epithelial-mesenchymal transition (EMT) process of cholangiocarcinoma. Opposite results were observed when CD39 was overexpressed. Mechanistically, CD39 could bind with Annexin A2 (ANXA2), which influences the phosphorylation level of ANXA2 at the Tyr24 site, thereby promoting the activation of PI3K/AKT signaling, which resulted in the biological change in cholangiocarcinoma. Conclusions: Our data indicated that CD39 was overexpressed in the tumor tissue. Meanwhile, CD39 was identified as an independent prognostic factor of poor overall survival for patients withcholangiocarcinoma. In terms of the biological role of CD39, our data indicated that CD39 promoted the progression and metastasis of cholangiocarcinoma through binding with ANXA2, and through activating the PI3K/AKT signaling. In brief, CD39 is a potential prognostic factor and therapeutical target for cholangiocarcinoma.

The Prognostic and Predictive Utility of CDX2 in Colorectal Cancer.

Caudal type homeobox transcription factor 2 (CDX2) is a gastrointestinal cancer biomarker that regulates epithelial development and differentiation. Absence or low levels of CDX2 have been associated with poor prognosis and proposed as a chemotherapy response predictor. Tumour tissue samples from 668 patients with stage I-IV colorectal cancer were stained for CDX2 and stratified into two subgroups according to expression levels. Statistical tests were used to evaluate CDX2's relationship with survival and chemotherapy response. Of 646 samples successfully stained, 51 (7.9%) had low CDX2 levels, and 595 (92.1%) had high levels. Low CDX2 staining was associated with poor differentiation and the presence of lymphovascular or perineural invasion and was more common in colon and right-sided tumours. Overall survival (p < 0.001) and disease-free survival (p = 0.009) were reduced in patients with low CDX2 expression. Multivariable analysis validated CDX2 as an independent poor prognostic factor after excluding confounding variables. There was no statistically significant improvement in survival with adjuvant chemotherapy in stage II colon cancer (p = 0.11). In the rectal cohort, there was no relationship between CDX2 levels and therapy response. While confirming the prognostic utility of CDX2 in colorectal cancer, our study highlights that larger studies are required to confirm its utility as a predictive chemotherapy biomarker, especially in left-sided and rectal cancers.

Useful biomarkers for predicting poor prognosis of patients with drug-induced liver injury: A retrospective cohort study

BackgroundDrug-induced liver injury (DILI) plays an important role in liver failure and causes mortality. Patients with DILI compatible with Hy's law are associated with poorer outcomes. However, the predictive accuracy of Hy's law is not good enough in clinical practice. This study aimed to investigate the optimal values of biomarkers associated with the prognosis of DILI. MethodsFrom June 1, 2014-May 30, 2022, patients with reported DILI were included. Patients' characteristics, drugs, DILI type, liver enzymes, and comorbidities were assessed. The associations with DILI-related comorbidities and survival were analyzed. ResultsNinety-five DILI patients were enrolled, 5 patients died of liver failure, and 23 patients died within 56 weeks after DILI. This study found that 15 mg/dL of total bilirubin, 1000 U/L of ALT, and 2 of PT-INR were optimal cut-off values in predicting DILI-related mortality. For the overall survival, patients with sepsis (HR:5.053, 95% CI:1.594–16.018, p = 0.006), malignancy (HR:4.371, 95% CI:1.573–12.147, p = 0.005), or end-stage renal disease (HR:7.409, 95% CI:1.404–39.103, p = 0.018) were independent poor prognostic factors in multivariate Cox regression analysis. ConclusionsTotal bilirubin >15 mg/dL, ALT >1000 U/L, and PT-INR >2 are useful biomarkers in predicting DILI-related mortality. DILI patients with sepsis, malignancy, or end-stage renal disease are associated with worse overall survival.

Evaluation of preoperative visceral fat area / psoas muscle area ratio and prognosis in patients with colorectal cancer

AbstractBackgroundRecent research has focused on the prognostic relevance of preoperative sarcopenia and sarcopenic obesity in various cancers. In this study we investigated the relationship between visceral fat area (VFA), psoas muscle area (PMA), and the prognosis of patients undergoing colorectal cancer surgery.MethodsPatients with stage III colorectal cancer who underwent surgery between July 2013 and April 2020 were included. The analysis was performed on 151 patients who met the criteria. The VFA and PMA were measured at the level of the third lumbar vertebra on computed tomography (CT) scans, and the ratio of VFA to PMA (V/P ratio) was determined.ResultsPatients with high V/P ratios were significantly older (p = 0.0213), had a higher body mass index (BMI) (p &lt; 0.0001), a higher percentage of sarcopenic obesity (p &lt; 0.0001), and more diabetes complications (p &lt; 0.0001). Prognostic analysis showed that the overall survival (OS) (p = 0.0154) and relapse‐free survival (RFS) (p = 0.0378) were significantly worse in patients with a high V/P ratio. Multivariate analysis revealed that a high V/P ratio was an independent poor prognostic factor for OS. Subgroup analysis was then performed in patients with BMI &lt; 25 kg/m2. OS (p = 0.0259) and RFS (p = 0.0275) were significantly worse in the high V/P ratio group. A high V/P ratio was an independent poor prognostic factor in the multivariate analysis.ConclusionIn colorectal cancer, the preoperative V/P ratio is an independent factor for poor prognosis. Preoperative evaluation of the V/P ratio may identify a wide range of high‐risk patients because it is an independent poor prognostic factor in patients without obesity.

IKZF3 amplification predicts worse prognosis especially in intestinal-type gastric cancer

PurposeIKAROS family zinc finger 3 (IKZF3) is an oncogene involved in different malignancies, particularly in the development and malignant progression of lymphocytes. However, IKZF3 amplification and clinical significance in gastric cancers (GCs) remain unexplored.MethodsWe examined IKZF3 amplification status in 404 GCs with HER2 amplification status using tissue microarray (TMA) and fluorescence in situ hybridization (FISH) assays.ResultsIKZF3 amplification was detected in 6.9% (28/404) of all GC patients, with higher rates in intestinal-type gastric cancer (IGC) (11.22%, 22/196) compared to other types (2.88%, 6/208). HER2 amplification was identified in 16.09% (65/404) of all GC patients, with higher rates in IGC (20.92%, 41/196) compared to other types (11.54%, 24/208). Co-amplification of IKZF3 and HER2 was detected in 8.16% (16/196) of IGC patients and in 2.40% (5/208) of other types. IKZF3 amplification showed significant correlation with IGC (P = 0.001) and HER2 amplification (P = 0.0001). IKZF3 amplification exhibited significantly worse disease-free survival (DFS) (P = 0.014) and overall survival (OS) (P = 0.018) in GC patients, particularly in IGC (DFS: P < 0.001; OS: P < 0.001), rather than other types. Cox regression analysis demonstrate IKZF3 amplification as an independent poor prognostic factor in all GCs (P = 0.006, P = 0.004 respectively) and in IGC patients, regardless of stages I-II or III-IV (P = 0.007, P = 0.004 respectively). On the other hand, HER2 amplification was significantly associated with worse DFS (P = 0.008) and OS (P = 0.01) in IGC patients, but not in all GCs and in multivariate analysis. Within the subset of patients with HER2 amplification, those also exhibiting IKZF3 amplification displayed potential poorer prognosis (P = 0.08, P = 0.11 respectively).ConclusionIKZF3 amplification was detected in minority of GC patients, especially in IGC, and was an independent indicator of poor prognosis. Our study, for the first time, found the prognostic value of IKZF3 was superior to HER2 for GC patients.

Sonic hedgehog expression in steatohepatitic hepatocellular carcinoma and its clinicopathological significance.

Hedgehog (Hh) signaling pathway dysregulation is involved in the pathogenesis of metabolic dysfunction-associated steatohepatitis, and the sonic Hh (SHh) protein, a pivotal molecule in the Hh pathway, is expressed in ballooned hepatocytes. The present study aimed to investigate the clinicopathological significance of SHh expression in steatohepatitic hepatocellular carcinoma (SH-HCC). Reverse transcription-quantitative polymerase chain reaction and immunohistochemistry were performed to examine SHh gene and SHh protein expression in SH-HCC. Additionally, patients with conventional HCC (C-HCC) were included in the control group. Comparisons of patient and tumor characteristics were also performed. The prevalence of SH-HCC was 3% in the whole cohort, and it was significantly associated with a high prevalence of diabetes mellitus. SHh mRNA was detected in all patients with SH-HCC, but not in 23% of patients with C-HCC. Notably, SHh mRNA expression was not significantly different between patients with SH-HCC and those with C-HCC; however, high SHh protein expression was significantly more frequent in SH-HCC patients than in those with C-HCC. Although the prognosis was not significantly different between the SH-HCC and C-HCC groups, high SHh protein expression was an independent poor prognostic factor for HCC. In conclusion, SHh could potentially serve as a therapeutic target for patients with HCC.

Outcomes of children with clear cell sarcoma of kidney following NWTS strategies in Shanghai China (2003-2021).

Although clear cell sarcoma of kidney (CCSK) is rare, it is the second most common renal tumor in children after Wilms' tumor. NWTS and SIOP are two major groups which had made tremendous efforts on renal tumors, but the strategies are different, for NWTS follows the upfront surgery principle providing definite pathology and the SIOP follows the upfront chemotherapy principle, each has its own advantages. Here we aimed to evaluate the outcomes of CCSK in China following NWTS strategies to analyze the prognostic factors. For this multicenter retrospective study, a total of 54 patients were enrolled from three children's hospitals, between April 2003 and December 2021. Treatment comprised upfront radical nephrectomy, followed by radiotherapy and intensive chemotherapy. Clinical records were regularly updated. Prognostic factors and survival rates were evaluated. The 54 enrolled patients had a median age of 37 months (range, 4 months to 11.4 years). The stage distribution was 16% stage I (n = 9), 30% stage II (n = 16), 39% stage III (n = 21), and 15% stage IV (n = 8). Among stage IV, metastasis sites included the lung (n = 6), bone (n = 1), and intra-orbital/cervical lymph node (n = 1). After a median follow-up of 5.6 years, the 5-year event-free survival (EFS) was 82.4±5.4%, and overall survival was 88.1±4.6%. The EFS was 100% for stage I, 93.8 ±6.1% for stage II, 71.1±10.0% for stage III, and 68.6±18.6% for stage IV. Univariate analysis revealed that staging (III/IV), tumor rupture, and inferior vena cava tumor thrombus were inferior prognostic factors. Multivariate analysis revealed that tumor rupture was independent poor prognostic factor (P = 0.01, HR 5.9). Among relapsed patients, relapse occurred a median of 11 months after diagnosis (range, 4-41 months), and 50% (4/8) achieved a second complete remission after multiple treatment. None of the six lung metastasis patients received lung RT, only one patient developed a relapse and was salvaged by RT after relapse. Tumor rupture was independent poor prognostic factor. Upfront surgery of NWTS strategies can make a definite pathology diagnosis, but how to reduce tumor rupture during surgery is important especially in developing countries. The outcomes of patients with stage I-III CCSK in China were comparable to findings in other developed countries. Better outcomes were achieved in stage IV CCSK by using an intensive chemotherapy regimen including carboplatin, which require further confirmation by AREN0321. Lung RT may be safely omitted in selected patients who achieve a compete radiographic response after 6 weeks of systemic treatment (including surgery). Treatment should be encouraged even in CCSK cases with metastasis and relapse.

Cancer histology in metastatic lymph node predicts prognosis in patients with node-positive stage IV colorectal cancer.

Appropriate prognostic indicators are required for patients with stage IV colorectal cancer (CRC). Lymph node metastasis mainly involves four histological types of CRC. Some metastatic lymph nodes (mLNs) showing cribriform carcinoma are associated with distant metastasis in patients with node-positive CRC and are correlated with recurrence and survival in stage III disease. However, the significance of mLN histology in the prognosis of patients with node-positive stage IV disease remains unclear. We enrolled 449 consecutive patients with CRC who underwent primary tumor resection with lymph node dissection between January 2011 and November 2018. This study included 88 patients with node-positive stage IV CRC and synchronous or metachronous distant metastases. We retrospectively investigated the association between cancer histology in the mLNs based on our classification and cancer-specific survival (CSS) in patients with node-positive stage IV CRC. Kaplan-Meier analysis showed that CSS was better in patients with CRC and all the mLNs showing tubular-type carcinoma. In contrast, patients with at least some mLNs showing poorly differentiated-type carcinoma had poor prognosis. Multivariate analysis showed that "all mLNs showing tubular-type carcinoma" was an independent good prognostic factor for CSS in patients with node-positive stage IV CRC. In addition, "at least some mLNs showing poorly differentiated-type carcinoma" was an independent poor prognostic factor for CSS in patients with node-positive stage IV disease. The histological type of the mLN may indicate a better or poor prognosis for patients with stage IV CRC.

Combination immunohistochemistry for CK5/6, p63, GATA6, and HNF4a predicts clinical outcome in treatment-naïve pancreatic ductal adenocarcinoma

Although sequence-based studies show that basal-like features lead to worse prognosis and chemotherapy-resistance compared to the classical subtype in advanced pancreatic ductal adenocarcinoma (PDAC), a surrogate biomarker distinguishing between these subtypes in routine diagnostic practice remains to be identified. We aimed to evaluate the utility of immunohistochemistry (IHC) expression subtypes generated by unsupervised hierarchical clustering based on staining scores of four markers (CK5/6, p63, GATA6, HNF4a) applied to endoscopic ultrasound-guided fine needle aspiration biopsy (EUS-FNAB) materials. EUS-FNAB materials taken from 190 treatment-naïve advanced PDAC patients were analyzed, and three IHC patterns were established (Classical, Transitional, and Basal-like pattern). Basal-like pattern (high co-expression of CK5/6 and p63 with low expression of GATA6 and HNF4a) was significantly associated with squamous differentiation histology (p < 0.001) and demonstrated the worst overall survival among our cohort (p = 0.004). IHC expression subtype (Transitional, Basal vs Classical) was an independent poor prognosticator in multivariate analysis [HR 1.58 (95% CI 1.01–2.38), p = 0.047]. Furthermore, CK5/6 expression was an independent poor prognostic factor in histological glandular type PDAC [HR 2.82 (95% CI 1.31–6.08), p = 0.008]. Our results suggest that IHC expression patterns successfully predict molecular features indicative of the Basal-like subgroup in advanced PDAC. These results provide the basis for appropriate stratification for therapeutic selection and prognostic estimation of advanced PDAC in a simplified manner.
