Prognostic Value of Holter Monitoring in Light Chain Amyloidosis.

(1) Background: To evaluate the predictive value of Holter monitoring for overall survival (OS) of patients with light chain amyloidosis (AL amyloidosis). (2) Methods: 137 patients with newly diagnosed AL amyloidosis who underwent Holter monitoring within 6 months of diagnosis were included. The primary outcome was OS. Landmark analysis was conducted at one-year follow-up. Independent predictors were determined using the log-rank test and multivariate Cox regression analysis. (3) Results: 131 (95.6%) patients received non-transplant therapy, and 32 (23.4%) underwent daratumumab-based chemotherapy. After a median follow-up of 20.3 months, 47 deaths occurred. Atrial tachycardia (AT), conduction delay, and non-sustained ventricular tachycardia (NSVT) were associated with poor OS one year beyond diagnosis in univariate analyses (patients with vs. without AT: 57.3% [95% confidence interval (CI): 47.2-67.4] vs. 81.0% (95% CI: 74.8-87.2), p = 0.039; patients with vs. without NSVT: 33.3% (95% CI: 8.5-58.1) vs. 75.3% (95% CI: 69.8-80.8), p = 0.024; patients with vs. without conduction delay: 41.7% (95% CI: 24.4-59.0) vs. 75.4% (95% CI: 69.7-81.1), p = 0.003]. AT [hazard ratio (HR): 2.6; 95% CI: 1.0-6.5; p = 0.049) and conduction delay (HR: 4.3; 95% CI: 1.3-14.3; p = 0.016) were independent predictors of OS after accounting for age and 2012 Mayo stage. (4) Conclusion: AT and conduction delay in Holter monitoring are independent predictors of poor OS one year beyond diagnosis in AL amyloidosis.

The proteasome component PSMD14 drives myelomagenesis through a histone deubiquitinase activity.

While 19S proteasome regulatory particle (RP) inhibition is a promising new avenue for treating bortezomib-resistant myeloma, the anti-tumor impact of inhibiting 19S RP component PSMD14 could not be explained by a selective inhibition of proteasomal activity. Here, we report that PSMD14 interacts with NSD2 on chromatin, independent of 19S RP. Functionally, PSMD14 acts as a histone H2AK119 deubiquitinase, facilitating NSD2-directed H3K36 dimethylation. Integrative genomic and epigenomic analyses revealed the functional coordination of PSMD14 and NSD2 in transcriptional activation of target genes (e.g., RELA) linked to myelomagenesis. Reciprocally, RELA transactivates PSMD14, forming a PSMD14/NSD2-RELA positive feedback loop. Remarkably, PSMD14 inhibitors enhance bortezomib sensitivity and fosters anti-myeloma synergy. PSMD14 expression is elevated in myeloma and inversely correlated with overall survival. Our study uncovers an unappreciated function of PSMD14 as an epigenetic regulator and a myeloma driver, supporting the pursuit of PSMD14 as a therapeutic target to overcome the treatment limitation of myeloma.

Patient Journey Toward a Diagnosis of Light Chain Amyloidosis in a National Sample: Cross-Sectional Web-Based Study.

BACKGROUND: Systemic light chain (AL) amyloidosis is a rare and multisystem disease associated with increased morbidity and a poor prognosis. Delayed diagnoses are common due to the heterogeneity of the symptoms. However, real-world insights from Chinese patients with AL amyloidosis have not been investigated. OBJECTIVE: This study aimed to describe the journey to an AL amyloidosis diagnosis and to build an in-depth understanding of the diagnostic process from the perspective of both clinicians and patients to obtain a correct and timely diagnosis. METHODS: Publicly available disease-related content from social media platforms between January 2008 and April 2021 was searched. After performing data collection steps with a machine model, a series of disease-related posts were extracted. Natural language processing was used to identify the relevance of variables, followed by further manual evaluation and analysis. RESULTS: A total of 2204 valid posts related to AL amyloidosis were included in this study, of which 1968 were posted on haodf.com. Of these posts, 1284 were posted by men (median age 57, IQR 46-67 years); 1459 posts mentioned renal-related symptoms, followed by heart (n=833), liver (n=491), and stomach (n=368) symptoms. Furthermore, 1502 posts mentioned symptoms related to 2 or more organs. Symptoms for AL amyloidosis most frequently mentioned by suspected patients were nonspecific weakness (n=252), edema (n=196), hypertrophy (n=168), and swelling (n=140). Multiple physician visits were common, and nephrologists (n=265) and hematologists (n=214) were the most frequently visited specialists by suspected patients for initial consultation. Additionally, interhospital referrals were also commonly seen, centralizing in tertiary hospitals. CONCLUSIONS: Chinese patients with AL amyloidosis experienced referrals during their journey toward accurate diagnosis. Increasing awareness of the disease and early referral to a specialized center with expertise may reduce delayed diagnosis and improve patient management.

Characteristics and outcomes of COVID-19 in patients with plasma cell dyscrasias during the first Omicron wave in Beijing since December 2022: a retrospective study at a National Clinical Research Center for Hematologic Disease.

The wave of coronavirus disease 2019 (COVID-19) with Omicron variant reached its first peak in Beijing, China in December 2022. We delineated characteristics and factors associated with adverse outcome of patients with plasma cell dyscrasias (PCDs) and COVID-19 during the first month of the wave. A total of 104 patients with a median age of 65 years were included in the study, with multiple myeloma (74%, n=77) and primary Immunoglobulin light chain amyloidosis (16.3%, n=17) being the two most common disease. Overall, severe or critical COVID-19 was developed in 18 (17.3%) patients, with a total all-cause mortality rate of 4.8% (n=5). The vaccination coverage was 41% and 48.1%, before and during the upsurge of Omicron, respectively, calling for the improvement of vaccination in PCD patients. Multivariable analysis revealed that age was the only independent risk factors (OR=1.14, 95% CI: 1.06-1.26, p = 0.002) associated with the development of severe or critical disease. Among patients with severe or critical group, low levels of albumin (HR=18.29; 95% CI: 1.82-183.44, p = 0.013) and high levels of lactic dehydrogenase (LDH) (HR=0.08; 95% CI: 0.01-0.65, p = 0.018) were associated with longer time to negative conversion of COVID-19.

COVID-19 infection in patients with haematological malignancies: A single-centre survey in the latest Omicron wave in China.

As the COVID-19 variant Omicron surge in Beijing, China, a better understanding of risk factors for adverse outcomes may improve clinical management in patients with haematological malignancies (HM) diagnosed with COVID-19. The study sample includes 412 cases, mainly represented by acute leukaemia, chronic myeloid leukaemia (CML), plasma cell disorders and lymphoma and chronic lymphocytic leukaemia. COVID-19 pneumonia was observed in 10.4% (43/412) of patients, and severe/critical illness was observed in 5.3% (22/412). Among the 86 cases with advanced malignancies, 17.6% (12/86) of patients developed severe/critical COVID-19, which was significantly higher than reported in patients with stable malignancies (9/326, 2.70%, p < 0.001). Similarly, the advanced malignancy cohort had a higher mortality rate (9/86, 10.5% vs. 0/326, 0%, p < 0.001) and a poor 30-day overall survival (OS) compared with the stable malignancy cohort (74.2% vs. 100.0%, p < 0.0001). Overall, nine patients (2.2%) died. The primary cause of death was progressive HM in four patients and a combination of both COVID-19 and HM in five patients. In the multivariable analysis, over 65 years of age, comorbidities and advanced malignancy were correlated with severe/critical COVID-19 in HM patients. This study sheds light on the poor outcomes among COVID-19 HM patients with the leading cause of advanced malignancy.

Impact of socio-demographic co-variates on prognosis, tyrosine kinase-inhibitor use and outcomes in persons with newly-diagnosed chronic myeloid leukaemia.

PURPOSE: Define the impact of socio-demographic co-variates on outcomes of persons with newly-diagnosed chronic phase chronic myeloid leukaemia (CML). METHODS: Data of 961 consecutive subjects with newly-diagnosed CML were integrated for these outcomes in multi-variable Cox regression analyses after adjusting for confounders and interactions. RESULTS: Elder age was associated with less use of a 2nd generation TKI as initial therapy. Household registration, comorbidity(ies) and education level were associated with use of a generic rather than branded TKI as initial therapy. Subjects with lower education level were more likely to be diagnosed with CML because of leukaemia-related symptoms. Rural registration and lower education level were also associated with a greater likelihood of switching TKI-therapy. Lower education level was associated with lower likelihood of achieving MMR [HR = 0.8 (0.7, 0.9), p = 0.002], MR4.5 [HR = 0.8 (0.7, 1.0), p = 0.055], and poor FFS [HR = 1.7 (1.3, 2.5); p < 0.001], PFS [HR = 2.0 (1.1, 5.0); p = 0.014], CML-related survival [HR = 2.5 (1.0, 10.0); p = 0.060] and survival [HR = 2.5 (1.0, 10.0); p = 0.043]. Males had lower rates of MMR and MR4.5 and worse FFS, but not survival compared with females. Being married was associated with a higher rate of MR4.5, fewer failures, progressions, and deaths. CONCLUSION: Socio-demographic co-variates have a strong impact on therapy choice and responses in persons with newly-diagnosed CML, including circumstances of diagnosis, risk category and prognosis, use of initial TKI, switching TKIs, response to TKI-therapy, and outcomes.

Health-related quality of life in children with chronic myeloid leukemia in the chronic phase.

PURPOSE: This study aimed to explore the health-related quality of life (HRQoL) and associated variables in children with chronic myeloid leukemia in the chronic phase (CML-CP) receiving tyrosine kinase inhibitors (TKIs). METHODS: A cross-sectional questionnaire was given to children with CML and their parents, who were < 18 years at diagnosis of CML and < 19 years at study. The questionnaire comprised three parts, including demographic information, clinical information, and the Chinese version of Pediatric Quality of Life Inventory™ (PedsQL™) Cancer Module 3.0 as HRQoL questionnaire. RESULTS: A total of 240 respondents data were analyzed. Multivariate analysis showed that children with symptoms had worse pain (- 10.2; P < 0.001), nausea (- 17.3; P = 0.001), more treatment anxiety (- 7.2; P = 0.005), worse self-assessment appearance (- 7.1; P = 0.001), communication problems (- 6.4; P = 0.001), and worse HRQoL (- 7.0; P < 0.001). Children with mothers having low educational qualifications had worse pain (- 6.0; P = 0.014), more worried about future (- 5.4; P = 0.042), worse cognition problems (- 7.1; P = 0.002), worse communication problems (- 5.5; P = 0.008), and worse HRQoL (- 4.3; P = 0.005). Younger age children at study had more procedural anxiety (2.7; P = 0.001), treatment anxiety (- 1.7; P = 0.014) and cognition problem (3.6; P < 0.001), as well as worse HRQoL (1.8; P = 0.008). However, older age children at diagnosis were more worried about future (- 2.8; P = 0.001), worse self-assessment appearance (- 1.1; P = 0.042) and worse HRQoL (- 1.8; P = 0.007). Other variables significantly associated with worse HRQoL included female gender, rural household registration and their father's low education level. Parents reported more gastrointestinal disorders, were worried about the future and had less concern about appearance than their children. CONCLUSIONS: Female gender, older age at diagnosis, younger age at study, lower mother's education level, and TKI-related symptoms are significantly associated with worse HRQoL in Children with CML. Children and their parents have different priorities in the HRQoL.

Association of emergence of new mutations in circulating tumuor DNA during chemotherapy with clinical outcome in metastatic colorectal cancer.

BACKGROUND: The understanding of molecular changes in mCRC during treatment could be used to personalise therapeutic strategies. The aim of our study was to explore the association of circulating tumour DNA (ctDNA) with clinical outcome in metastatic colorectal cancer (mCRC). METHODS: Sequential patients with mCRC receiving standard first-line chemotherapy were included prospectively. Both plasma ctDNA and serum CEA were assessed in samples obtained before treatment and after 4 cycles of chemotherapy (C4). Computed tomography (CT) scans were carried out at baseline and post-C4 (8-10 weeks) and were assessed using Response Evaluation Criteria In Solid Tumours version 1.1 (RECIST v1.1). Target-capture deep sequencing with a panel covering 1021 genes was performed to detected somatic mutations in ctDNA. RESULTS: A total of 20 patients were prospectively included and treated with either leucovorin, fluorouracil, and oxaliplatin (FOLFOX) (15/20) or leucovorin, fluorouracil, and irinotecan (FOLFIRI) (5/20). Median follow-up was 6.9 months (range 1.6-26.6). Somatic mutations for baseline ctDNA analysis were identified in 85% (17/20) of the patients. Mutation variations of ctDNA after chemotherapy were tested in 16/20 (80.0%) of the patients. In multivariate analyses, a high baseline molecular tumour burden index (mTBI) in ctDNA was associated with a higher risk of disease progression, as well as emergence of new mutations in ctDNA during chemotherapy. Patients with newly detected mutations had shorter progression-free survival (PFS) compared to those without (median 3.0 versus 7.3 months; hazard ratio (HR), 5.97; 95% confidence interval (CI), 0.70-50.69; P = 0.0003). Fold changes in mTBI from baseline to post-C4 were obtained in 80.0% (16/20) of the patients, which were also related to PFS. Patients with fold reduction in mTBI above 0.8-fold had longer PFS compared to those below (median 9.3 versus 4.1 months; HR, 4.51; 95% CI, 1.29-15.70; P = 0.0008). CONCLUSIONS: Newly detected mutations in ctDNA during treatment might potentially be associated with clinical outcome in mCRC and may provide important clinical information.

Mental Health in Persons With Chronic Myeloid Leukemia During the SARS-CoV-2 Pandemic: The Need for Increased Access to Health Care Services.

Mental health problems in the general population have been reported during the SARS-CoV-2 pandemic; however, there were rare data in persons with chronic myeloid leukemia (CML). Therefore, we performed a cross-sectional study on mental health evaluated using the 9-item Patient Health Questionnaire (PHQ-9; depression), the 7-item Generalized Anxiety Disorder (GAD-7; anxiety), and the 22-item Impact of Event Scale-Revised (IES-R; distress), including subscales of avoidance, intrusion, and hyper-arousal in persons with CML, non-cancer persons, and immediate family members of persons with cancer as controls (≥16 years) by an online survey. Data from 3,197 persons with CML and 7,256 controls were collected. In multivariate analyses, CML was significantly associated with moderate to severe depression (OR = 1.6; 95% Confidence Interval [CI], 1.4, 1.9; p < 0.001), anxiety (OR = 1.4 [1.1, 1.7]; p = 0.001), distress (OR = 1.3 [1.1, 1.5]; p < 0.001), and hyper-arousal (OR = 1.5 [1.3, 1.6]; p < 0.001). Moreover, delay in regular monitoring was significantly associated with depression (OR 1.3 [1.0, 1.7]; p = 0.024), anxiety (OR = 1.3 [1.0, 1.8]; p = 0.044), avoidance (OR = 1.2 [1.0, 1.4]; p = 0.017), and intrusion (OR = 1.2 [1.0, 1.4]; p = 0.057); tyrosine kinase-inhibitor dose reduction or discontinuation, depression (OR = 1.9 [1.3, 2.8]; p = 0.001), distress (OR = 2.0 [1.4, 2.8]; p < 0.001), avoidance (OR = 1.6 [1.2, 2.1]; p = 0.004), intrusion (OR = 1.6 [1.1, 2.1]; p = 0.006), and hyper-arousal (OR = 1.3 [1.0, 1.8]; p = 0.088). We concluded that persons with CML during the SARS-CoV-2 pandemic have worse mental health including depression, anxiety, and distress symptoms. Decreasing or stopping monitoring or dose resulted in adverse mental health consequences.

Adolescents experienced more treatment failure than children with chronic myeloid leukemia receiving imatinib as frontline therapy: a retrospective multicenter study.

To explore the differences in the clinical features, treatment responses, and outcomes among children, adolescents, and adults with chronic myeloid leukemia in the chronic phase (CML-CP) receiving imatinib as first-line therapy. Data from children (0-8 years for girls and 0-10 years for boys), adolescents (9-19 years for girls and 11-19 years for boys), and adults (age ≥ 20 years) with newly diagnosed CML-CP receiving imatinib as first-line therapy between 2006 and 2019 were retrospectively reviewed. In total, 135 children (cohort 1), 189 adolescents (cohort 2), and 658 adults (cohort 3: age 20-39 years, n = 305; cohort 4: age 40-59 years, n = 270; and cohort 5: age 60-83 years, n = 83) were included in this study. When compared with children, adolescents showed a significantly higher white blood cell count (P = 0.033) and basophil percentage in peripheral blood (P = 0.002) and a significantly higher prevalence of splenomegaly (P = 0.004). Both children and adolescents presented with more aggressive clinical features than adults. During median follow-ups of 28 months (range, 3-161 months) in children, 33 months (range, 3-152 months) in adolescents, and 48 months (range, 3-157 months) in adults, multivariate analysis showed that children and adolescents had higher probabilities of achieving complete cytogenetic response, major molecular response, and molecular response4.5. Notably, compared with not only adults (cohort 3 vs. cohort 1: HR = 2.03 [1.03, 3.98], P = 0.040; cohort 4 vs. cohort 1: HR = 2.15 [1.07, 4.33], P = 0.033; cohort 5 vs. cohort 1: HR = 4.22 [1.94, 9.15], P < 0.001) but also adolescents (cohort 2 vs. cohort 1: HR = 2.36 [1.18, 4.72], P = 0.015), children had significantly longer failure-free survival. Age was not associated with progression-free survival or overall survival. Although they exhibited more aggressive clinical features at diagnosis, both children and adolescents achieved superior treatment responses than adults. Adolescents showed even more adverse features and a poor FFS than children.

Evolution of late-stage metastatic melanoma is dominated by aneuploidy and whole genome doubling.

Although melanoma is initiated by acquisition of point mutations and limited focal copy number alterations in melanocytes-of-origin, the nature of genetic changes that characterise lethal metastatic disease is poorly understood. Here, we analyze the evolution of human melanoma progressing from early to late disease in 13 patients by sampling their tumours at multiple sites and times. Whole exome and genome sequencing data from 88 tumour samples reveals only limited gain of point mutations generally, with net mutational loss in some metastases. In contrast, melanoma evolution is dominated by whole genome doubling and large-scale aneuploidy, in which widespread loss of heterozygosity sculpts the burden of point mutations, neoantigens and structural variants even in treatment-naïve and primary cutaneous melanomas in some patients. These results imply that dysregulation of genomic integrity is a key driver of selective clonal advantage during melanoma progression.

Comparable Efficacy and Safety of Generic Imatinib and Branded Imatinib in Patients With Newly Diagnosed Chronic Myeloid Leukemia With a Consideration of Socioeconomic Characteristics: A Retrospective Study From a Single Center.

INTRODUCTION: To compare the efficacy and safety of generic and branded imatinib in adults with newly diagnosed chronic myeloid leukemia in the chronic phase (CML-CP), we retrospectively reviewed data from patients CML-CP who received generic or branded imatinib. PATIENTS AND METHODS: A propensity score matching (PSM) study was performed. A Cox regression model was used to identify factors associated with responses and outcomes. RESULTS: Four hundred forty-two adults receiving generic imatinib (n = 236) or Glivec (Novartis, Basel, Switzerland; n = 206) were included. There were more patients with rural household registration (P < .001), lower education level (P < .001), divorced or widowed status (P = .009), higher white blood cell counts (P = .019), splenomegaly (P < .001), and longer intervals from diagnosis to imatinib initiation (P = .033) in the generic cohort. During the follow-up, there was no significant difference between the 2 cohorts in the 4-year probabilities of achieving a complete cytogenetic response (97.0% vs. 97.3%; P = .736), major molecular response (87.8% vs. 90.1%; P = .113), and molecular response4.5 (32.5% vs. 38.8%; P = .186), as well as failure-free survival (77.3% vs. 81.4%; P = .313), progression-free survival (94.4% vs. 95.8%; P = .489), and overall survival (96.8% vs. 98.3%; P = .088). Multivariate analyses showed that the drug type was not associated with responses and outcomes. After the PSM procedure, 177 pairs of patients with comparable baseline characteristics were reanalyzed. Multivariate analyses confirmed that generic or branded imatinib used as first-line therapy was not associated with either responses or outcomes. CONCLUSION: Sociodemographic characteristics might influence the tyrosine kinase inhibitor that patients chose. Generic and branded imatinib as first-line therapy had comparable efficacy and safety in CML-CP patients.

Planned Pregnancy in Female Patients with Chronic Myeloid Leukemia Receiving Tyrosine Kinase Inhibitor Therapy.

BACKGROUND: The aim of this study was to explore outcomes of planned pregnancy in female patients with chronic myeloid leukemia (CML) on tyrosine kinase inhibitors (TKIs). MATERIALS AND METHODS: Data of female patients proceeding with a planned pregnancy were retrospectively reviewed. RESULTS: A total of 17 patients with CML who achieved at least a major molecular response (MMR) during imatinib (n = 13) or nilotinib (n = 4) therapy prior to a planned pregnancy were enrolled. At the time of TKI interruption, six were in MMR, two in molecular response 4 (MR4), and nine in molecular response 4.5 (MR4.5). TKI therapy was discontinued 6 weeks (range, 2-15 weeks) before conception in 4 patients and at gestational age of 4 weeks (range, 2-5 weeks) after determination of pregnancy in 13 patients. Apart from 1 patient who suffered a spontaneous abortion, 16 patients delivered uneventfully. A total of 10 patients lost MMR after stopping TKIs; 8 lost molecular response 2, and 3 lost complete hematological response. Log-rank analyses showed achieving MR4 (p = .030) or MR4.5 (p = .031), complete cytogenetic response duration ≥3.5 years (p = .049), and MMR duration ≥3.5 years (p = .040) were significantly associated with longer MMR-failure-free survival during TKI interruption. CONCLUSION: Planned pregnancy might be pragmatic in female patients with CML on TKIs. Achieving deep molecular response and, importantly, MMR duration ≥3.5 years were significantly associated with maintaining MMR during pregnancy. IMPLICATIONS FOR PRACTICE: Female patients with chronic myeloid leukemia on tyrosine kinase inhibitors (TKIs) wishing to conceive are currently advised to discontinue TKIs before conception. However, the ideal degree and duration of response before stopping TKI, in addition to whether there will be any adverse effect caused by a short exposure of TKI, is unknown. Data of 17 female patients, who achieved at least a major molecular response (MMR) before TKI interruption, was revised, and it was found that achieving deep molecular response and MMR duration ≥3.5 years was significantly associated with maintaining MMR during pregnancy. This provides direct evidence for a planned pregnancy strategy, and stopping TKI immediately after determination of pregnancy in female patients might be pragmatic.

Single Nucleotide Polymorphisms of Paclitaxel-induced Peripheral Sensory Neuropathy in Chinese Han Population.

Objective To study the single nucleotide polymorphisms (SNPs)that predict a patient's risk of grade 2-3 paclitaxel-induced peripheral sensory neuropathy (PSN) in Chinese Han populations.Methods Totally 216 patients received paclitaxel in Peking Union Medical College Hospital from May 2014 to December 2016 were enrolled.DNA was isolated from peripheral blood.Genotyping for eight candidate SNPs was performed on Sequenom-MassARRARYiPLEX platform.Patients were followed up and PSN was assessed by trained physicians according to National Cancer Institute-Common Terminology Criteria for Adverse Events v4.03.Results A total of 209 patients entered the final analysis.Among the candidate SNPs,only rs4141404:A>C(LIMK2) was significantly associated with grade 2/3 PSN (OR:4.32,95%CI:2.37-7.89,P<0.0001).In multivariate logistic regression analysis,both rs4141404:A>C(LIMK2) and history of receiving platinum compound (OR:2.70,95%CI:1.32-5.51,P=0.007) were associated with grade 2/3 PSN.Conclusion rs4141404:A>C(LIMK2) may be the markers of risk of grade 2/3 PSN.

KLF17 Expression in Colorectal Carcinoma and Its Clinical Significance.

OBJECTIVE: To detect KLF17 expression in colorectal carcinoma (CRC) and to evaluate its effect on the prognosis of colorectal carcinoma. METHODS: Immunohistochemistry was performed to detect the expression of KLF17 in CRC and matched pericarcinous tissue,and the relationship between KLF17 expression and disease-free survival (DFS) was analyzed. RESULTS: Of 73 CRC patients, KLF17 expression was positive in 32 patients and negative in 41 patients. KLF17 expression rate was significantly lower in CRC tissue than in pericarcinous tissue (χ(2)=12.418, P=0.001). The DFS of KLF17-positive stage III colon cancer patients was (56.3±7.2) months (95% CI: 42-70 months), which was significantly longer than that [(32.3±5.5) months (95% CI: 22-43 months)] of KLF17-negative patients (P=0.039). CONCLUSION: KLF17 expression decreases in CRC tissue, and a positivie KLF17 expression predicts a better prognosis in stage III CRC patients.

Cancer biomarkers and personalized cancer medicine.

The development of cancer biomarkers has brought the treatment of cancer from the tumor type-based to molecular target-based,and the latter marks the introduction of personalized cancer medicine (PCM). However,each individual tumor has unique molecular information,and the real PCM should be focused on single individuals and their specific molecular identities.
