Abstract
A 70-year-old man had radical surgery for colon cancer one year before the symptoms of memory loss and decreasing cognitive function. Subsequent magnetic resonance imaging revealed a brain mass, which was surgically resected and confirmed to be metastatic intestinal adenocarcinoma. Immunohistochemistry of the primary tumor and brain metastasis showed mismatch repair deficiency. The patient received adjuvant chemotherapy after surgery. However, the brain metastasis relapsed one month after the last chemotherapy. Genetic testing on the resected colon tumor samples confirmed microsatellite instability-high with a high tumor mutation burden by 77.7 muts/Mb. The patient was subsequently treated with programmed death-1 (PD-1) monoclonal antibody pembrolizumab (keytruda). The brain metastatic lesions were completely shrunk, and a complete clinical response was achieved.

Anti-VEGF Therapy Possibly Extends Survival in Patients With Colorectal Brain Metastasis by Protecting Patients From Neurologic Disability. Clin Colorectal Cancer 2023; 22:267-279. [PMID: 37098452 DOI: 10.1016/j.clcc.2023.03.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 03/20/2023] [Accepted: 03/23/2023] [Indexed: 03/30/2023]
Abstract
BACKGROUND Colorectal brain metastases (CBMs) are rare with poor prognosis. There is still no standard systemic treatment for multiple or unresectable CBM. our study aimed to explore the impact of anti-VEGF therapy on overall survival, brain-specific disease control, and neurologic symptom burden in patients with CBM. METHODS A total of 65 patients with CBM under treatment were retrospectively enrolled and divided into anti-VEGF based systemic therapy or non-anti-VEGF based therapy. A total of 25 patients who received at least 3 cycles of anti-VEGF agent and 40 patients without anti-VEGF therapy were analyzed by endpoints of overall survival (OS), progression-free survival (PFS), intracranial PFS (iPFS) and neurogenic event-free survival (nEFS). Gene expression in paired primary metastatic colorectal cancer (mCRC), liver, lung and brain metastasis from NCBI data was analyzed using top Gene Ontology (GO) and cBioPortal. RESULTS Patients who treated with anti-VEGF therapy had significantly longer OS (19.5 vs. 5.5 months, P = .009), iPFS (14.6 vs. 4.1 months, P < .001) and nEFS (17.6 vs. 4.4 months, P < .001). Patients who received anti-VEGF therapy beyond any disease progression presented with superior OS (19.7 vs. 9.4 months, P = .039). Top GO and cBioPortal analysis revealed a stronger molecular function of angiogenesis in intracranial metastasis. CONCLUSIONS Anti-VEGF based systemic therapy showed favorable efficacy that was reflected in longer overall survival, iPFS and NEFS in patients with CBM.

Abstract
OPINION STATEMENT Compared to liver and lung metastases, brain metastases (BMs) from colorectal cancer (CRC) are rare and remain poorly investigated despite the anticipated rise in their incidence. CRC patients bearing BM have a dismal prognosis with a median survival of 3-6 months, significantly lower than that of patients with BM from other primary tumors, and of those with metastatic CRC manifesting extracranially. While liver and lung metastases from CRC have more codified treatment strategies, there is no consensus regarding the treatment of BM in CRC, and their management follows the approaches of BM from other solid tumors. Therapeutic strategies are driven by the number and localisation of the lesion, consisting in local treatments such as surgery, stereotactic radiosurgery, or whole-brain radiotherapy. Novel treatment modalities are slowly finding their way into this shy unconsented armatorium including immunotherapy, monoclonal antibodies, tyrosine kinase inhibitors, or a combination of those, among others.This article reviews the pioneering strategies aiming at understanding, diagnosing, and managing this disease, and discusses future directions, challenges, and potential innovations in each of these domains. HIGHLIGHTS • With the increasing survival in CRC, brain and other rare/late-onset metastases are rising. • Distal colon/rectal primary location, long-standing progressive lung metastases, and longer survival are risk factors for BM development in CRC. • Late diagnosis and lack of consensus treatment strategies make BM-CRC diagnosis very dismal. • Liquid biopsies using circulating tumor cells might offer excellent opportunities in the early diagnosis of BM-CRC and the search for therapeutic options. • Multi-modality treatment including surgical metastatic resection, postoperative SRS with/without WBRT, and chemotherapy is the best current treatment option. • Recent mid-sized clinical trials, case reports, and preclinical models show the potential of unconventional therapeutic approaches as monoclonal antibodies, targeted therapies, and immunotherapy.

Treatment of brain metastases from gastrointestinal primaries: Comparing whole-brain radiotherapy and stereotactic radiosurgery in terms of survival. North Clin Istanb 2022; 9:47-56. [PMID: 35340309 PMCID: PMC8889206 DOI: 10.14744/nci.2021.65725] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/13/2021] [Accepted: 10/25/2021] [Indexed: 02/01/2023] Open
Abstract
Objective: The objective of the study was to analyze the clinical features and prognostic factors for survival in patients with brain metastasis (BM) from gastrointestinal primaries treated with whole-brain radiotherapy (WBRT) or stereotactic radiosurgery (SRS). Methods: We retrospectively investigated patients with BMs resulting from gastrointestinal primaries who underwent WBRT or SRS. The effects of treatment modalities on overall survival (OS) were calculated by the Kaplan–Meier method. Results: WBRT and SRS were applied to 24 and 17 patients, respectively. In the WBRT group, radiotherapy was delivered at 20–30 Gy in 5–10 fractions (fx). In the SRS group, a median dose of 22 Gy (range: 18–27 Gy) was applied in 1–3 fx. At BM diagnosis, all patients had synchronous extracranial metastases which were mostly detected in the lung and liver. Median OS values were 9 months and 4 months in the SRS and WBRT groups, respectively (p=0.005). Karnofsky performance status (KPS) score (≥70 vs. <70), diagnosis-specific graded prognostic index, gastrointestinal (GI) graded prognostic index, cumulative intracranial tumor volume (CITV), controlled systemic disease, and treatment modality (WBRT vs. SBRT) were found to be related with OS. Conclusion: In patients with GI cancer-related BMs, SRS should be preferred in those with longer OS expectancy who have controlled extracranial disease, good KPS and CITV values of <10 cm3.

Abstract
Background Brain metastasis (BM) of colorectal cancer is a disease with a poor prognosis of only a few months survival. However, it is difficult to estimate the individual prognosis of each patient due to the lack of definitive prognosis parameters. The number of metastases and the Karnofsky performance score are known predictors for survival. We investigated whether or not the neurological performance score and the tumor volumetrics are equally suitable predictors for survival. Design All patients with histologically diagnosed BM linked to colorectal cancer between 2012 and March 2020 were reviewed. The Medical Research Council Neurological Performance Score was used to quantify neurological performance. Univariate analysis with Kaplan-Meier estimate and log-rank test was performed. Survival prediction and multivariate analysis were performed employing Cox proportional hazard regression. Results Twenty-five patients were included in our analysis with an overall survival of 4.9 months after surgery of the BM. Survival decreased in the univariate analysis with increasing postoperative neurological performance score, low Karnofsky performance score, absence of radiation therapy and radiation therapy modality. The neurological performance score is a reliable scoring parameter for estimating the prognostic course analogous to the Karnofsky performance score. Neither preoperative nor post resection residual tumor volume had any impact on overall survival in our small cohort. Conclusion Our data suggest that the postoperative neurological performance is a valuable prognostic factor for colorectal cancer patients with BM. Tumor volumetrics show no correlation to survival. Further investigations with a larger number of cases are mandatory. Supplementary Information The online version contains supplementary material available at 10.1186/s12885-022-09435-1.

Abstract
Most patients with colorectal cancer (CRC) were diagnosed in advanced stage and the prognosis is poor. Therefore, early detection and prevention of CRC are very important. As with other cancers, there is also the tertiary prevention for CRC. The primary prevention is etiological prevention, which is mainly the treatment of adenoma or inflammation for preventing the development into cancer. The secondary prevention is the early diagnosis and early treatment for avoiding progressing to advanced cancer. The tertiary prevention belongs to the broad category of prevention, mainly for advanced CRC, through surgical treatment and postoperative adjuvant chemotherapy, radiotherapy, targeted therapy, immunotherapy for preventing tumor recurrence or metastasis. This consensus is based on the recent domestic and international consensus guidelines and the latest progress of international researches in the past five years. This consensus opinion seminar was hosted by the Chinese Society of Gastroenterology and Cancer Collaboration Group of Chinese Society of Gastroenterology, and was organized by the Division of Gastroenterology and Hepatology & Shanghai Institute of Digestive Disease, Renji Hospital, School of Medicine, Shanghai Jiao Tong University. The consensus opinion contains 60 statement clauses, the standard and basis of the evidence-based medicine grade and voting grade of the statement strictly complied with the relevant international regulations and practice.

Abstract
Purpose This study aimed to analyze clinicopathological, survival, prognostic factors, as well as the timing of brain metastases (BM) in colorectal cancer (CRC) using data from a Chinese center. Patients and Methods Data of 65 consecutive CRC patients with BM were collected from a single institution in China. The time from primary tumor surgery to the occurrence of BM was calculated. Kaplan-Meier analysis was used to evaluate cumulative survival of patients. Factors associated with prognosis of overall survival (OS) were explored using Cox's proportional hazard regression models. Results The median time interval from CRC surgery to the diagnosis of BM was 24 months. After diagnosis of BM, median OS values for patients were 11 months. Extracranial metastases occurred in 45 cases (69.2%) when BM was diagnosed, and 58.5% of these patients with lung metastases Time of BMs (P=0.018), presence of extracranial metastases (P=0.033), treatment (P=0.003), CA199 (P=0.034), CA125 (P<0.001), CA242 (P=0.018), and CA211 (P=0.012) were associated with OS of patients through univariate analysis. Multivariate analysis using a Cox regression model showed that only treatment was an independent predictor for OS (conservative treatment; HR=1.861, 95% CI=1.077-3.441; P=0.048). Conclusion Surgical treatment of metastatic lesions may be an alternative choice for CRC patients with BM. Identifying the timing of brain metastases can help to detect this disease early, leading to a better survival outcome.

Clinical, histopathological and immunohistochemical features of brain metastases originating in colorectal cancer: a series of 27 consecutive cases. ROMANIAN JOURNAL OF MORPHOLOGY AND EMBRYOLOGY 2021; 61:81-93. [PMID: 32747898 PMCID: PMC7728123 DOI: 10.47162/rjme.61.1.09] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Indexed: 12/23/2022]
Abstract
Introduction: Brain metastases (BMs) originating in colorectal cancer (CRC) have a significant importance for patients’ survival. Because in literature there are only isolated case reports and only few series published on this issue, we aimed to assess the incidence of BMs from CRC, to identify patient’s characteristics and BMs clinical, histopathological (HP) and immunohistochemical (IHC) features, and to compare the data we obtained with those from literature. Patients, Materials and Methods: We present a retrospective study of 27 histologically confirmed cases of BMs from CRC among all 1040 patients who received metastasectomy in the Department of Neurosurgery, Prof. Dr. Nicolae Oblu Emergency Clinical Hospital, Iaşi, Romania, in an eight-year period (January 2011 to December 2018). Patients’ characteristics (gender, age), primary tumor location, time from primary tumor surgery to BMs surgery and BMs features (number, location and HP characteristics) were investigated. Histochemical [Alcian Blue (AB) and Periodic Acid–Schiff (PAS)] staining and IHC stainings for cytokeratin (CK) 7, CK20, caudal-type homeobox 2 (CDX2) and human epidermal growth factor receptor 2 (HER2)/neu were performed on all available BMs specimens. Results: There were 27 consecutive patients with BMs from CRC, corresponding to 2.59% of all patients with BMs during the eight-year period we have studied, most of them being diagnosed and treated in 2016. Male:female ratio was 1.45. The mean age for all patients at diagnosis of the BMs was 62.25 years (range: 40–79 years). The origin of the primary cancer was mainly the colon (62.96% of all cases). Of all 27 patients, only two (7.4%) presented neurological symptoms without a diagnosis of CRC. BMs were identified in a period ranging from six months to 70 months after the initial diagnosis. The average time between diagnosis of the primary tumor and of the BMs was 25.92 months. At the moment of the diagnosis of BMs, 17 (62.96%) patients also had other systemic metastases. Most of the cases (55.55%) were situated in the supratentorial compartment. IHC stainings were negative for CK7 and positive for CK20 and CDX2 in all BMs from colonic adenocarcinomas (ADCs), a profile consistent with a non-neuronal and gastric origin. AB and PAS stainings revealed pools of extracellular mucin, especially in cases of mucinous ADC. Ki67 labeling index ranged between 90% and 100%. IHC staining with anti-HER2/neu antibody showed in 25 (96.15%) cases a strong and diffuse aberrant nuclear staining. Conclusions: BMs originating in CRC represent a rare pathology and have particular clinical and IHC features that could vary from one series to another series. In a few cases, BMs may be diagnosed in the absence of a known CRC diagnosis and in these situations, the correct diagnosis is of interest. However, a panel of antibodies can help in establishing a correct diagnosis. Our study was among the first to analyze the HER2/neu expression pattern in BMs from CRC and we found a strong aberrant nuclear expression of this molecular marker on IHC investigation. Related to the data published so far in the literature, it is possible that HER2/neu aberrant expression in the tumor nuclei of the BMs from our series may express the metastatic tumor cell phenotype that was previously subjected to cytostatics and radiation therapies. As such, we suggest that HER2/neu aberrant expression in BMs originating in CRC could represent a proof for the worst prognosis of these patients.

Abstract
BACKGROUND Brain metastases (BMs) from colorectal cancer (CRC) are unusual; however, an increase in incidence has been reported. The evidence available on the subject is scarce, and a better understanding is warranted. We aimed to characterize the epidemiology and the outcomes of patients with BMs from CRC. PATIENTS AND METHODS A cohort of patients with BMs from CRC was retrospectively evaluated. Patients were treated in a single center between May 2008 and April 2019. BMs were confirmed by brain computed tomography or magnetic resonance imaging. RESULTS A total of 247 consecutive patients were evaluated. Most patients had a left-sided primary tumor (193, 78%) and at least two extra-cranial metastatic sites (194, 78%). Ninety-six patients (39%) were RAS wild-type; 68 patients (27%) were RAS mutated; and 83 patients (34%) were not characterized. Median time from the initial diagnosis to BMs was 27.6 months (interquartile range, 13.1-46.9). Regarding local therapy, 43 patients (17.4%) were treated with BM surgery alone, 76 patients (30.8%) with radiotherapy (RT) alone, and 58 patients (23.5%) with both surgery and RT. Median overall survival (OS) was 2.9 months (95% confidence interval [CI], 2.2-3.5). Six-month and 1-year OS rates were 29% (95% CI, 23-25) and 13.5% (95% CI, 9.2-18.6), respectively. In a multivariable analysis, BM surgery alone (hazard ratio [HR], 0.56; P = .018), RT alone (HR, 0.51; P = .001), and surgery plus RT (HR, 0.27; P < .001) were associated with superior OS, whereas Eastern Cooperative Oncology Group Performance Status 3 or 4 (HR, 2.01; P = .009) and male gender (HR, 1.46; P = .012) were negative prognostic factors. RAS status was not associated with OS. CONCLUSION BMs occur late during the course of colorectal cancer and are more common in patients with a left-sided primary tumor and a high volume of metastatic disease. BMs from colorectal cancer are still associated with an extremely poor prognosis; however, selected patients may benefit from treatment with surgical resection and radiotherapy.

Abstract
The number of deaths from colorectal cancer in Japan continues to increase. Colorectal cancer deaths exceeded 50,000 in 2016. In the 2019 edition, revision of all aspects of treatments was performed, with corrections and additions made based on knowledge acquired since the 2016 version (drug therapy) and the 2014 version (other treatments). The Japanese Society for Cancer of the Colon and Rectum guidelines 2019 for the treatment of colorectal cancer (JSCCR guidelines 2019) have been prepared to show standard treatment strategies for colorectal cancer, to eliminate disparities among institutions in terms of treatment, to eliminate unnecessary treatment and insufficient treatment and to deepen mutual understanding between healthcare professionals and patients by making these guidelines available to the general public. These guidelines have been prepared by consensuses reached by the JSCCR Guideline Committee, based on a careful review of the evidence retrieved by literature searches and in view of the medical health insurance system and actual clinical practice settings in Japan. Therefore, these guidelines can be used as a tool for treating colorectal cancer in actual clinical practice settings. More specifically, they can be used as a guide to obtaining informed consent from patients and choosing the method of treatment for each patient. Controversial issues were selected as clinical questions, and recommendations were made. Each recommendation is accompanied by a classification of the evidence and a classification of recommendation categories based on the consensus reached by the Guideline Committee members. Here, we present the English version of the JSCCR guidelines 2019.

Brain metastases in colorectal cancer: prognostic factors and survival analysis. Int J Colorectal Dis 2018; 33:1517-1523.

Abstract
PURPOSE Colorectal cancer (CRC) brain metastases (BM) are an uncommon and late event. We aim to investigate the impact of clinical factors, treatment modalities and RAS/BRAF status on the outcomes of CRC patients with BM. PATIENTS We retrospectively analysed CRC patients who developed BM in our centre between January 1997 and June 2017. Clinical factors, treatment modalities, RAS/BRAF status and survival were evaluated. RESULTS Twenty-eight patients were recorded; 82% had left-sided (LS) CRC and 71% had lung metastases. Median time to BM diagnosis was 36 months (m) and 93% of patients received local treatment of BM (43% whole brain radiotherapy, 50% surgery). Right-sided (RS) CRC showed shorter time to BM, not previously described (9.3 vs 46.6 m for RS and LS CRC, respectively; HR = 4.7, p = 0.006). Median overall survival (mOS) from BM treatment was 9.5 m, better in patients who underwent surgery than those treated with radiotherapy alone (12.1 vs 4.6 m, respectively; HR = 0.3, p = 0.019) and in those without progressive metastatic extracranial disease (7.2 vs 20.9 m, for progressive and non-progressive, respectively; HR = 0.3, p = 0.056). Patients with two or more metastatic extracranial locations showed worse prognosis (5.9 vs 16.3 m, for > 2 vs 0-1, respectively; HR = 3.7, p = 0.015). RAS/BRAF status did not showed prognostic value. CONCLUSIONS Time to BM diagnosis is shorter in RS CRC. The presence of two or more metastatic extracranial locations and progressive metastatic extracranial disease at the time of BM diagnosis could be bad prognosis factors for CRC BM patients.
