[PMID: 37894424 PMCID: PMC10605032 DOI: 10.3390/cancers15205057] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/16/2023] [Revised: 10/01/2023] [Accepted: 10/17/2023] [Indexed: 10/29/2023] Open
Abstract
The role of upfront primary tumor resection (PTR) in patients with unresectable metastatic colorectal cancer without severe symptoms remains controversial. We retrospectively analyzed the role of PTR in overall survival (OS) in this population. Among the 205 patients who enrolled, the PTR group (n = 42) showed better performance (p = 0.061), had higher frequencies of right-sided origin (p = 0.058), the T4 stage (p = 0.003), the M1a stage (p = 0.012), and <2 organ metastases (p = 0.002), and received fewer targeted agents (p = 0.011) than the chemotherapy group (n = 163). The PTR group showed a trend for longer OS (20.5 versus 16.0 months, p = 0.064) but was not related to OS in Cox regression multivariate analysis (p = 0.220). The male sex (p = 0.061), a good performance status (p = 0.078), the T3 stage (p = 0.060), the M1a stage (p = 0.042), <2 organ metastases (p = 0.035), an RAS wild tumor (p = 0.054), and the administration of targeted agents (p = 0.037), especially bevacizumab (p = 0.067), seemed to be related to PTR benefits. Upfront PTR could be considered beneficial in some subgroups, but these findings require larger studies to verify.

Abstract
BACKGROUND Various prognostic factors have been reported for bone metastases from different primary tumor sites. However, bone metastases from colorectal cancer are very rare, and the prognostic factors have not been investigated in detail. OBJECTIVE This study aimed to identify prognostic factors of bone metastases from colorectal cancer. DESIGN This is a retrospective cohort study using data from a prospectively collected database. SETTINGS This study was conducted at a single tertiary care cancer center in Japan. PATIENTS Patients who developed bone metastases from colorectal cancer during the study period among all patients who received initial treatment for colorectal cancer at our hospital between 2005 and 2016 (n = 4538) were included. MAIN OUTCOME MEASURES Overall survival after diagnosis of bone metastases from colorectal cancer was the main outcome measure. RESULTS Ninety-four patients developed bone metastases during the study period. The 5-year overall survival rate was 11.0%. Multivariable analysis identified the following independent risk factors associated with poor prognosis: ≥70 years of age at diagnosis of bone metastases (HR, 2.48; 95% CI, 1.24-4.95; p < 0.01), curative surgery not performed as initial treatment (HR, 2.54; 95% CI, 1.24-5.19; p = 0.01), multiple bone metastases (HR, 2.44; 95% CI, 1.30-4.57; p < 0.01), albumin level <3.7 g/dL (HR, 3.80; 95% CI, 1.95-7.39; p < 0.01), CEA ≥30 ng/mL (HR, 1.94; 95% CI, 1.09-3.46; p = 0.02), and less than 3 chemotherapy options remaining at diagnosis of bone metastases (HR, 2.83; 95% CI, 1.51-5.30; p < 0.01). The median survival times for patients with 0-2, 3, and 4-6 risk factors were 25.0, 8.8, and 4.3 months, respectively. LIMITATIONS The main limitation is the single-center, retrospective design of this study. CONCLUSIONS Our results may facilitate multidisciplinary decision-making in patients with bone metastases from colorectal cancer. See Video Abstract at http://links.lww.com/DCR/B930 .

Mortality of patients with metastatic colorectal cancer who received elective or emergent operation after exposure to bevacizumab: A nationwide database study. EUROPEAN JOURNAL OF SURGICAL ONCOLOGY 2023; 49:445-451. [PMID: 36208981 DOI: 10.1016/j.ejso.2022.09.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 08/05/2022] [Accepted: 09/28/2022] [Indexed: 12/24/2022]
Abstract
INTRODUCTION Treatment guidelines for colorectal cancer (CRC) indicate that surgical intervention within 4 weeks or 8 weeks after bevacizumab therapy might increase the risk of postoperative complications and mortality, especially in patients who received emergent operation. Therefore, we aimed to assess the association between different surgical timings, emergent or elective surgery, and the risk of postoperative mortality. MATERIALS AND METHODS Using the Taiwan National Health Insurance Database and Taiwan Cancer Registry, we identified patients with metastatic colorectal cancer (mCRC) who underwent surgery within 1 year of receiving bevacizumab between January 2010 and December 2017. The primary outcomes were 30-day, 60-day, and in-hospital mortality; the secondary outcomes were hospital stay, 30-day readmission rate, and surgical complications. Multivariate analysis was used to adjust for confounders. RESULTS This study included 2,047 patients. In the multivariate analysis, patients who underwent emergent operation and had higher Charlson scores had a significantly higher mortality rate. Patients with a longer interval to surgery, more cycles of bevacizumab treatment, and distal metastectomy had the opposite result. In subgroup analysis, patients who received emergent operation within 28 days had the highest surgical mortality. CONCLUSIONS The interval to operation among mCRC patients who receive bevacizumab treatment should exceed 4 weeks to avoid additional risk of mortality whether patients receiving elective or emergent operation. Patients who received emergent operation within 28 days of bevcizumab infusion had the highest risk of mortality.

Abstract
Primary tumor resection may be unfeasible in metastatic colorectal cancer. We determined the effects of bevacizumab and cetuximab therapies on survival or conversion surgery in patients with metastatic colorectal cancer who did not undergo primary tumor resection. This retrospective cohort study enrolled 8466 patients who underwent first-line bevacizumab- or cetuximab-based therapy. We analyzed the data of both therapies in patients who did not undergo primary tumor resection. Overall survival after targeted therapy plus chemotherapy was assessed. The groups were matched using propensity score matching and weighting. Cetuximab resulted in lower mortality than bevacizumab (hazard ratio (HR) = 0.75); however, it did not have the same effect in patients that underwent primary tumor resection (HR = 0.95) after propensity score weighting. Among patients treated with targeted agents, primary tumor resection was associated with lower mortality among those who received both bevacizumab (HR = 0.60) and cetuximab (HR = 0.75). Among patients that did not undergo primary tumor resection, multivariable analysis for conversion surgery showed that the cetuximab group (HR = 1.82) had a significantly higher metastasectomy rate. In these patients, cetuximab-based therapy was associated with significantly better survival compared with bevacizumab-based therapy. Cetuximab also yielded a higher conversion surgery rate. These findings demonstrate the importance of stratification by primary tumor resection in the application of current treatment guidelines and initiation of future clinical trials.

Abstract
BACKGROUND Many reports suggest more activity of cytotoxic chemotherapy among patients with metastatic colorectal cancer (mCRC) who experience neutropenia, but it is not clear whether this finding is related to drug effect alone. The aim of the study is to identify the characteristics of patients whose peripheral blood cell kinetics (PBCK) is related to the outcome. METHODS The study is a retrospective analysis of patients with mCRC who had received first-line chemotherapy at Sanremo hospital from 2010 to 2015, evaluating seventeen baseline variables, six related to systemic inflammatory response activation (SIRA), and six to peripheral blood cell kinetics after one cycle. The relationship of peripheral blood cell kinetics variables was evaluated by tumor location, SIRA, and timing of metastases. RESULTS Among 203 eligible patients, only four variables were able to independently predict survival (age, CA 19-9, number of drugs, chemotherapy-induced leukopenia after the first cycle or CIL-1). After stratification by tumor location or by SIRA, no relationship of PBCK variables with prognosis was present. On the contrary, after stratification by timing of metastasis, the prognostic role of CIL-1 was evident among patients with metachronous metastases, particularly among those with low SIRA and colon tumors, whereas the leukocyte reduction after the first cycle (WR) predicted longer survival of patients with synchronous metastases and a previous resection of the primary tumor (PTR). CONCLUSIONS Absolute leukocyte reduction (CIL-1) predicts a better OS of patients with metachronous metastases, whereas relative leukocyte reduction (WR) could be prognostic among patients with synchronous metastases who have received PTR.

Recurrence hazard of rectal cancer compared with colon cancer by adjuvant chemotherapy status: a nationwide study in Japan. J Gastroenterol 2021; 56:371-381.

Abstract
BACKGROUND Previous studies of stage III colon cancer using the hazard function demonstrated that the risk of recurrence in patients with adjuvant chemotherapy never exceeded that of patients without adjuvant chemotherapy. However, it is unclear whether the same can be said for rectal cancer patients and whether adjuvant chemotherapy reduces recurrence. This study aimed to compare the recurrence hazard of stage III rectal cancer with that of colon cancer by adjuvant chemotherapy status using the hazard function, a method that allows for the assessment of instantaneous risk of recurrence over time. METHODS This retrospective nationwide study consisted of 10,356 patients with stage III colorectal cancer who underwent curative resection between January 1997 and December 2012 in Japan. Recurrence hazards of rectal and colon cancers were compared between patients treated with adjuvant chemotherapy and those who were not. Analyses in which recurrence was divided into local and distant recurrence were also performed. RESULTS The hazard rate of recurrence in rectal cancer patients with adjuvant chemotherapy was consistently lower throughout the follow-up period, and the peak time of recurrence later, compared to patients without adjuvant chemotherapy (peaked at 15.7 vs. 7.1 months). Adjuvant chemotherapy also strongly suppressed distant recurrence but not local recurrence in rectal cancer patients. Similar results were observed in colon cancer patients. CONCLUSIONS Our results using nationwide real-world data in Japan suggest that, similar to what is observed in colon cancer patients, adjuvant chemotherapy delays the peak of recurrence and suppresses distant recurrence in stage III rectal cancer patients.

Abstract
Approximately 10% of patients with colorectal cancer (CRC) develop malignant large bowel obstruction (MLBO) at diagnosis. Furthermore, for 35% of patients with MLBO, curative primary tumor resection is unfeasible because of locally advanced disease and comorbidities. The practice of placing a self-expandable metallic stent (SEMS) has dramatically increased as an effective palliative treatment. Recent advances in systemic chemotherapy for metastatic CRC have significantly contributed to prolonging patients' prognosis and expanding the indications. However, the safety and efficacy of systemic chemotherapy in patients with SEMS have not been established. This review outlines the current status of this relatively new therapeutic strategy and future perspectives. Some reports on this topic have demonstrated that 1) systemic chemotherapy and the addition of molecular targeted agents contribute to prolonged survival in patients with SEMS; 2) delayed SEMS-related complications are a major concern, and this requires strict patient monitoring; however, primary tumor control by chemotherapy might result in decreased complications, especially regarding re-obstruction; and 3) using bevacizumab could be a risk factor for SEMS-related perforation, which may be lethal. Although this relatively new approach for unresectable stage IV obstructive CRC requires a well-planned clinical trial, this therapy could be promising for patients who are unideal candidates for emergency surgery and require immediate systemic chemotherapy.

Abstract
AIM In patients with incurable metastatic colorectal cancer (mCRC), resection of the primary tumour is debated; however, patients with intact primaries may be at a higher risk of complications requiring surgery when receiving treatment with bevacizumab. Our aim was to estimate the risk of nonelective colorectal surgery in patients undergoing bevacizumab therapy for mCRC and evaluate the association between intact primary tumours and risk of nonelective surgery. METHOD We designed a population-based, retrospective cohort study using administrative and cancer registry data in Ontario, Canada. We included patients with mCRC who received bevacizumab from 1 January 2008 to 31 December 2014. The primary outcome was nonelective colorectal surgery after initiation of bevacizumab. We determined the cumulative incidence of nonelective colorectal surgery among patients with previously resected and unresected primaries, accounting for the competing risk of death. We explored the relationship between previous resection of the primary and need for nonelective surgery using a cause-specific hazards model, controlling for patient, tumour and treatment factors. RESULTS We identified 1840 (32.7%) patients with intact primaries and 3784 (67.3%) patients with prior resection. The cumulative incidence of nonelective surgery 1 year after initiating bevacizumab for all patients was 3.9% (95% CI 3.4-4.5%). One-year cumulative incidence was higher in those with intact primaries than in those with resected primaries (6.1% vs 2.9%, P < 0.0001). After adjustment, an intact primary remained strongly associated with nonelective colorectal surgery (hazard ratio = 2.89, 95% CI 2.32-3.61; P < 0.0001). CONCLUSION Bevacizumab is associated with a low but meaningful risk for serious gastrointestinal complications, necessitating vigilance, particularly among patients with an intact primary tumour.

Abstract
Background With recommendation of surgical management in primary site, both the positive and negative lymph nodes (LNs) retrieved have been emphasized to predict prognosis in stage IV rectum cancer. Therefore, we attempt to compare the prognostic performance of American Joint Committee on Cancer (AJCC) N-stage relative to lymph node ratio (LNR), log odds of metastatic lymph nodes (LODDS), and N-score in stage IV rectal cancer. Methods Total 5,090 patients taken surgical resection of primary site in rectum cancer with distant metastasis were extracted from Surveillance, Epidemiology, and End Results Program (SEER) database. Harrell's C statistic (C-index) and Akaike's Information Criterion (AIC) were used to evaluate the discriminative ability of the different LN staging systems. Results Of the 3,243 patients without radiotherapy, 82.46% (n=2,675) had been found with lymph nodes metastasis with median number of 16 lymph nodes collected (IQR: 11-22). Modeled as categorical cutoff variables for further clinical usage, when number of LNs was between 12 and 25 (C-index: 0.5997, AIC: 1,698.015), 8th AJCC N-stage outperformed other three schemas with increasing C-index and less AIC value. Assessed as continuous values, the LODDS shown as the best schemas with greatest discriminatory power (C-index: 0.5971, AIC: 3,680.017), generally. On the other hand, in the cohorts of other 1274 patients taken radiation, the median number of lymph nodes retrieved was 13 (IQR: 9-18). LODDS still remained remarkable performance as continuous (C-index: 0.5912; AIC: 1,058.765) and categorical variables (C-index: 0.5700; AIC: 1,061.703), while N-staging outperformed with less than 25 lymph nodes retrieved (LNs <12 C-index: 0.5678, AIC: 481.94; 12< LNs <25 C-index: 0.5933, AIC: 390.395). Conclusions When assessed as categorical variables, N-stage performed superiorly with adequate lymph nodes examined, whether the patients have got radiotherapy prior to surgery or not. LODDS showed, when assessed as a continuous variable, good discriminative ability and goodness of fit in predicting survival for stage IV rectum cancer patients regardless of radiation therapy status.

Abstract
BACKGROUND The goal of this study was to delineate the patterns of distant metastasis from colon adenocarcinoma (CAC) and evaluate the survival differences by metastatic patterns. METHODS Using the Surveillance, Epidemiology, and End Results (SEER) database, we extracted patients diagnosed with stage IV CAC between 2010 and 2016. Kaplan-Meier survival curves were plotted with log-rank tests to compare overall survival (OS) of patients with different metastatic patterns. Univariate and multivariate Cox proportional hazards regression models were used to evaluate the effects of different metastatic patterns on survival outcomes in terms of OS and disease-specific survival (DSS). RESULTS A total of 26 170 patients were analyzed. The 3- and 5-year OS were 20.7% and 10.5%, respectively, for patients with stage IV CAC. The most common distant metastatic site was the liver, followed by the lung, bone, and brain, but the frequency differed greatly by histology subtypes. The site of metastasis was a significant prognostic factor for OS and DSS in patients with stage IV CAC, independent of the number of metastatic sites and other clinical and demographic prognostic factors. Using liver-only metastasis as reference, lung-only metastasis was associated with better OS (hazard ratio [HR] = 0.82, 95% confidence interval [CI], 0.71-0.94) and DSS (HR = 0.75, 95% CI, 0.64-0.88). Older age, black race, unmarried status, grade III/IV tumors, advanced tumor-node-metastasis (TNM) stage, proximal colon, elevated preoperative carcinoembryonic antigen (CEA), no surgery of the primary site, and no chemotherapy were independent predictors of poor OS. CONCLUSIONS The site of distant metastasis and number of metastasis site were independent prognostic factors for survival of patients with stage IV CAC. This study highlights the need for diverse treatment strategies for patients with different metastatic patterns.

Prognostic impact of preoperatively elevated and postoperatively normalized carcinoembryonic antigen levels following curative resection of stage I-III rectal cancer. Cancer Med 2019; 9:653-662. [PMID: 31799750 PMCID: PMC6970051 DOI: 10.1002/cam4.2758] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/31/2019] [Revised: 10/24/2019] [Accepted: 11/21/2019] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND Preoperative and early postoperative serum carcinoembryonic antigen (CEA) levels are known prognostic factors in rectal cancer. Recently, a large-scale study on colon cancer revealed that "preoperatively elevated and postoperatively normalized CEA levels" is not an indicator of poor prognosis. However, whether this hold true in rectal cancer patients is unknown. This study aimed to investigate the prognostic significance of preoperatively elevated and postoperatively normalized CEA levels in rectal cancer patients undergoing curative resection. METHODS Subjects were consecutive stage I-III rectal cancer patients who underwent curative resection without preoperative treatment at National Cancer Center Hospital between 2000 and 2015. Overall survival (OS) and the hazard function of recurrence or death were analyzed according to the CEA levels, as follows: normal preoperative CEA (normal group), preoperatively elevated but postoperatively normalized CEA (normalized group), and preoperatively and postoperatively elevated CEA (elevated group). RESULTS The normalized group (n =235) had worse OS (HR 1.49, 95% CI 1.08-2.04; P = .0142) compared to the normal group (n = 1208), and better OS compared to the elevated group (n = 47) (HR 0.53, 95% CI 0.31-0.91; P = .0208). The elevated group had the highest and earliest peak in hazard function, followed by the normalized group and the normal group, with median times to recurrence of 8.8, 15.5, and 18.5 months, respectively (P = .0223). CONCLUSIONS Prognosis after resection of rectal cancer was worse in patients with preoperatively elevated and postoperatively normalized CEA compared to those with normal preoperative CEA. Patients with elevated preoperative CEA might require intensive follow-up even if levels normalize after resection, especially in earlier periods, for early detection of recurrence.
