Background
The value of microscopic biliary and perineural invasion as prognostic biomarkers in patients with resectable colorectal liver metastases (CLM) who undergo neoadjuvant chemotherapy and liver resection is still unclear. This retrospective study was performed to elucidate this issue.Methods
Histologic slides of resected CLM of patients who underwent neoadjuvant bevacizumab-based chemotherapy and liver resection were investigated with respect to biliary and perineural invasion. Presence of invasion was correlated with radiologic and histologic response, recurrence-free survival (RFS) and overall survival (OS).Results
One hundred forty-one patients were enrolled. There was a significant association between biliary and perineural invasion, respectively (P = 0.001). Moreover, both biliary and perineural invasion were associated with bilobar metastatic spread and higher number of metastases, while perineural invasion was also associated with a higher Fong score. No significant association was found with response. In univariable analysis, biliary and perineural invasion were associated with shorter RFS (median 10.1 vs. 13.5 months, HR 2.09, P = 0.010 and 7.6 vs. 14.0, HR 2.23, P = 0.001, respectively). Biliary invasion was also associated with shorter OS (median 32.8 months vs. not reached, HR 2.78, P = 0.010), however these results did not remain significant in multivariable analysis.Conclusions
In patients with resectable colorectal liver metastases undergoing neoadjuvant bevacizumab-based chemotherapy and liver resection, biliary and perineural invasion are associated with higher tumor load but may not be prognostic biomarkers. 相似文献2.

Background
Increasingly, patients with multiple colorectal liver metastases (CLM) are surgically treated. Some studies have shown that patients with bilobar and unilobar multiple CLM have similar outcomes, but other have shown that patients with bilobar CLM have worse outcomes after resection. We aimed to compare clinical outcomes of surgical treatment of bilobar and unilobar CLM using propensity score matching.Methods
The single-institution study included patients who underwent hepatectomy for ≥3 histologically confirmed CLM during 1998–2014. Clinicopathologic characteristics and long-term outcomes were compared between patients with bilobar and unilobar CLM in a propensity-score-adjusted cohort.Results
A total of 473 patients met the inclusion criteria, 271 (57%) with bilobar and 202 (43%) with unilobar CLM. In the propensity-score-matched population (bilobar, 170; unilobar, 170), no differences were observed according to the distribution of CLM except for a greater frequency of concomitant ablation, and R1 resection in the bilobar group. There was no difference between the bilobar and unilobar groups in 5-year overall survival rates (46% and 49%, respectively; P = 0.740) or 3-year recurrence-free survival rates (21% and 24%, respectively; P = 0.674).Conclusions
Tumor distribution may not affect the curability of surgery for multiple CLM. Liver resection would be justified for selected patients with bilobar CLM. 相似文献3.

Background
Hepatic vascular inflow occlusion (VIO) can be applied during resection of colorectal liver metastases (CRLM) to control intra-operative blood loss, but has been linked to accelerated growth of micrometastases in experimental models. This study aimed to investigate the effects of hepatic VIO on disease-free and overall survival (DFS and OS) in patients following resection for CRLM.Methods
All patients who underwent liver resection for CRLM between January 2006 and September 2015 at our center were analyzed. Hepatic VIO was performed if deemed indicated by the operating surgeon and severe ischemia was defined as ≥20 min continuous or ≥45 min cumulative intermittent VIO. Cox regression analysis was performed to identify predictive factors for DFS and OS.Results
A total of 208 patients underwent liver resection for CRLM. VIO was performed in 64 procedures (31%), and fulfilled the definition of severe ischemia in 40 patients. Patients with severe ischemia had inferior DFS (5-year DFS 32% vs. 11%, P < 0.01), and inferior OS (5-year OS 37% vs. 64%, P < 0.01). At multivariate analysis, a high clinical risk score (Hazard ratio (HR) 1.60 (1.08–2.36)) and severe ischemia (HR 1.89 (1.21–2.97)) were independent predictors of worse DFS. Severe ischemia was not an independent predictor of OS.Conclusion
The present cohort study suggests that prolonged hepatic VIO during liver resection for CRLM was associated with reduced DFS. A patient-tailored approach seems advisable although larger studies should confirm these findings. 相似文献4.

Background
The prognosis of patients undergoing liver resection for colorectal liver metastases (CLM) seems to be altered when the primary tumour is right-sided. However, data are lacking and conflicting. We aimed to evaluate the influence of the primary tumour location on oncologic outcomes following such surgery.Methods
We retrospectively analysed prospectively collected data from 376 consecutive patients who underwent liver surgery for CLM between June 2010 and August 2015. We compared the outcomes of patients with right colon tumours and those with left colorectal tumours. The splenic flexure was used as the cut-off point to determine the anatomic primary site.Results
Among the 364 patients eligible, 74 (20.3%) had a right-sided primary tumour. These patients were older, had a poorer American Society of Anaesthesiologists status and had fewer node-positive primary tumours. The CLM characteristics were similar between both groups. Median PFS was not significantly different between the two groups at 9.9 months, as well as the pattern of recurrence. Median OS was shorter for patients with right-sided primary tumour (34.6 versus 45.3 months, p = 0.035). Similar results were observed when patients with rectal tumour were excluded from analysis (34.6 vs. 47.5 months, p = 0.007). Primary tumour site was an independent prognosis factor in multivariate analysis.Conclusion
Right-sided location of the primary tumour is associated with worse OS after surgery for CLM, but seems to have no influence on PFS, and on the pattern of recurrence. 相似文献5.

Background
Surgical resection is an established therapeutic strategy for colorectal cancer (CRC) metastasis. However, controversies exist when CRC liver and lung metastases (CLLMs) are found concomitantly or when recurrence develops after either liver or lung resection. No predictive score model is available to risk stratify these patients in preparation for surgery, and cure has not yet been reported.Patients and Methods
All consecutive patients who had undergone surgery for CLLMs at our institution during a 20-year period were reviewed. Our policy was to propose sequential surgery of both sites with perioperative chemotherapy, if the strategy was potentially curative. Overall survival, disease-free survival, and cure were evaluated.Results
Sequential resection was performed in 150 patients with CLLMs. The median number of liver and lung metastases resected was 3 and 1, respectively. The median follow-up period was 59 months (range, 7-274 months). The median, 5-year, and 10-year overall survival was 76 months, 60%, and 35% respectively. CRC that was metastatic at the initial diagnosis (P = .012), a prelung resection carcinoembryonic antigen level > 100 ng/mL (P = .014), a prelung resection cancer antigen 19-9 level > 37 U/mL (P = .034), and an interval between liver and lung resection of < 24 months (P = .024) were independent poor prognostic factors for survival. The 5-year survival was significantly different for patients with ≤ 2 and ≥ 3 risk factors (77.3% vs. 26.5%). Of 75 patients with ≥ 5 years of follow-up data available from the first metastasis resection, 15 (20%) with disease-free survival ≥ 5 years were considered cured. The use of targeted therapy was the only independent predictor of cure.Conclusion
Curative-intent surgery provides good long-term survival and offers a chance of cure in select patients. Patients with ≤ 2 risk factors are good candidates for sequential resection. 相似文献6.

Background
We evaluated a series of oligometastatic colorectal cancer (CRC) patients treated with stereotactic ablative body radiotherapy (SABR) delivered in all active lung metastases.Patients and Methods
Forty-four patients with 69 lung metastases were treated with SABR. Eleven patients presented with other sites of metastases before stereotactic body radiotherapy (SBRT), even though they had controlled/cured systemic disease.Results
The median follow-up was 36 months. The median overall survival (OS) was 38 months and 2 years, 3-year OS rates were 67.7% and 50.8%, respectively. The median progression-free survival (PFS) was 10 months and 2 years, 3-year PFS rates were 20.3% and 16.2%, respectively. Local recurrence occurred in 16 patients (36%).The first site of failure was local only in 22%, distant only in 35%, and local and distant in 14% of the patients. The 1-year, 2-year, and 3-year local PFS (LPFS) were 68.8%, 60.2%, and 54.2%, respectively. No Grade ≥ 3 toxicities were recorded in the univariate analysis; multiple lung metastases and synchronous oligometastatic disease were significantly associated with worse PFS (P = .04, and P < .001, respectively) and worse metastases-free survival (MFS; P = .04, and P < .001, respectively). The type of response was identified as a significant prognostic factor for OS (P = .014), PFS (P = .006), and LPFS (P < .001). In multivariate analysis single lung metastases treated with SBRT was associated with better MFS (P = .015). Metachronous oligometastatic disease and type of response were associated with significantly better PFS.Conclusion
Stereotactic body radiotherapy is a valid therapy in the treatment of lung metastases for oligometastatic CRC patients presenting long survival. The rate of local control remains lower compared with other primaries. Further prospective cohorts would better evaluate effective fractionation for patients with oligometastatic CRC. 相似文献7.
Background
While the indications for surgery among patients with colorectal cancer liver metastases (CRCLM) are expanding, the role of surgery in patients with hepatic lymph node involvement remains controversial. We report management and outcomes in a population-based cohort of patients undergoing hepatectomy with concomitant hepatic lymphadenectomy for CRCLM.Methods
All cases of hepatectomy for CRCLM in the Canadian Province of Ontario from 2002 to 2009 were identified using the population-based Ontario Cancer Registry and linked electronic records of treatment. Pathology reports were used to identify concomitant lymphadenectomy with liver resection as well as extent of disease and surgical procedure.Results
Among 1310 patients who underwent resection for CRCLM, 103 (8%) underwent simultaneous regional lymphadenectomy. Seventy-one percent of cases with lymphadenectomy (70/103) had a major liver resection (≥3 segments). Of the 103 lymphadenectomy cases, 80 (78%) were hepatic pedicle, 16 (16%) were celiac and 7 (7%) were para-aortic. The mean number of nodes removed was 2.2 (range 1–15). Ninety-day mortality was 6%. Twenty-nine percent (30/103) of cases had positive nodes. Unadjusted overall survival at 5 years for positive vs negative nodes was 21% vs 42% (p = 0.003); cancer-specific survival was 10% vs 43% (p < 0.001). In adjusted analyses, hepatic node involvement was associated with inferior OS (HR 2.19, p = 0.010) and CSS (HR 3.07, p = 0.002).Conclusions
Patients with resected CRC liver metastases with regional lymph node involvement have inferior survival compared to patients with negative nodes. Despite this poor prognostic factor, a small proportion of cases with involved nodes will achieve long-term survival. 相似文献8.

Background
The neutrophil-to-lymphocyte ratio (NLR), which reflects the cancer-induced systemic inflammation response, has been proposed as a risk factor for poor long-term prognosis in cancer. We investigated the prognostic role of the NLR and the relationship between the NLR and TNM stage in pancreatic ductal adenocarcinoma (PDAC) patients following curative resection.Methods
One-hundred thirty-eight consecutive patients with resected PDAC were enrolled between 2004 and 2014. Univariate and multivariate analyses identified variables associated with overall survival (OS) and recurrence-free survival (RFS). Patients were stratified according to the NLR, with an NLR cut-off value of 2.2 being estimated by receiver operating characteristic curve.Results
Compared to patients with a low NLR (≤2.2), those with a high preoperative NLR (>2.2) had worse OS and RFS (P = 0.017, P = 0.029, respectively). For early-stage tumors, tumor size ≥20 mm and a high NLR were independent risk factors for poor OS (hazard ratio (HR): 3.255, 95% confidence interval (CI): 1.082–9.789, P = 0.036; HR: 3.690, 95% CI: 1.026–13.272, P = 0.046, respectively) and RFS (HR: 3.575, 95% CI: 1.174–10.892, P = 0.025; HR: 5.380, 95% CI: 1.587–18.234, P = 0.007, respectively). The NLR was not correlated with prognosis in patients with advanced stages.Conclusions
An elevated preoperative NLR was an important prognosticator for early TNM stage PDAC. The NLR, which is calculated using inexpensive and readily available biomarkers, could be a novel tool for predicting long-term survival in patients, especially those with early stage PDAC. 相似文献9.

Introduction
There is an ongoing controversy surrounding portal vein embolization (PVE) regarding the short-term safety of PVE and long-term oncological benefit. This study aims to compare survival outcomes of patients subjected to major liver resection for colorectal liver metastases (CRLM) with or without PVE.Methods
All consecutive patients who underwent major liver resection for CRLM in four high volume liver centres between January 2000 and December 2015 were included. Major liver resection was defined as resection of at least three Couinaud liver segments. To reduce selection bias, propensity score matching was performed for PVE and non-PVE patients with overall and disease-free survival as primary endpoints. For matching, all patients who underwent PVE followed by a major liver resection were selected. Patients were matched to patients who had undergone major liver resection without PVE.Results
Of 745 patients undergoing major liver resection for CRLM, 53 patients (7%) underwent PVE before liver resection. In the overall cohorts, PVE patients had inferior DFS and a trend towards inferior OS. A total of 46 PVE patients were matched to 46 non-PVE patients to create comparable cohorts and between these two matched cohorts no differences in DFS (3-year DFS 16% vs 9%, p = 0.776) or OS (5-year OS 14% vs 14%, p = 0.866) were found.Conclusions
This retrospective, matched analysis does not suggest a negative impact of PVE on long-term outcomes after liver resection in patients with CRLM. 相似文献10.

Background
Neutropenia is a common side effect associated with docetaxel use. We retrospectively investigated the association between chemotherapy-induced neutropenia and survival in metastatic castration-resistant prostate cancer (mCRPC) patients receiving first-line docetaxel.Patients and Methods
Metastatic castration-resistant prostate cancer patients treated with first-line docetaxel, with known neutrophils value 10 days after first administration, were included in this retrospective analysis. Neutropenia was categorized in Grade 0 to 1 (G0-1), Grade 2 to 3 (G2-3), and Grade 4 (G4). Outcome measures were progression-free survival (PFS) and overall survival (OS).Results
Eighty patients were analyzed. Median PFS was 5.4 months in patients with G0-1 neutropenia, 6.9 months with G2-3 neutropenia (hazard ratio [HR] vs. G0-1, 0.69; 95% confidence interval [CI], 0.35-1.35; P = .27) and 9.5 months with G4 neutropenia (HR vs. G0-1, 0.30; 95% CI, 0.16-0.57; P < .0001). Median OS was 11.6 months in patients with G0-1 neutropenia, 25.5 months in patients with G2-3 neutropenia (HR vs. G0-1, 0.36; 95% CI, 0.16-0.80; P = .012) and 39.3 months in patients with G4 neutropenia (HR vs. G0-1, 0.19; 95% CI, 0.09-0.41; P < .0001). In multivariate analysis, the occurrence of severe neutropenia showed a statistically significant association with OS (HR G4 vs. G0-1, 0.14; 95% CI, 0.03-0.67; P = .013; HR G2-3 vs. G0-1, 0.42; 95% CI, 0.11-1.57; P = .20) and PFS (HR G4 vs. G0-1, 0.28; 95% CI, 0.09-0.86; P = .03; HR G2-3 vs. G0-1, 1.07; 95% CI, 0.38-2.96; P = .90).Conclusion
Docetaxel-induced neutropenia is associated with better survival of mCRPC. 相似文献11.

Background
In addition to established prognostic factors, individual lifestyle-associated factors, such as obesity, physical activity, and diet, seem to modulate the course of breast cancer. The aim of this analysis was to evaluate the influence of weight changes during adjuvant chemotherapy on outcome in a large multicenter prospectively randomized trial.Patients and Methods
The ADEBAR trial compares a sequential chemotherapy consisting of epirubicin/cyclophosphamide followed by docetaxel to an epirubicin/5-fluorouracil/cyclophosphamide regimen in patients with lymph node–positive early breast cancer. Body weight was measured before each cycle of chemotherapy. According to the relative weight change (≥ 5%) between the first and the last cycle, patients were categorized into the weight gain, weight loss, or stable weight group. Overall survival (OS) and disease-free survival were assessed by univariate Kaplan-Meier and multivariate Cox regression analyses.Results
Concise data from 1080 of 1493 participants who completed all cycles of chemotherapy were available for analysis. Of 307 patients (24.8%) whose weight changed by ≥ 5%, 120 patients (11.1%) lost and 187 (17.3%) gained weight. Multivariate analysis showed a significant independent effect of weight change on OS (P = .039), but not on disease-free survival (P = .111). Both weight change groups had a worse OS compared to patients with stable weight (weight gain: hazard ratio, 1.55; 95% confidence interval, 1.01-2.40; P = .047; weight loss: hazard ratio, 1.55; 95% CI, 0.97-2.47; P = .067).Conclusion
Weight change of > 5% during adjuvant chemotherapy in patients with high-risk early breast cancer is associated with poor OS. 相似文献12.

Background
Hepatic resection is considered the optimal potentially curative treatment for colorectal liver metastases (CRLM). Following resection, up to two-thirds of patients will develop recurrence within 5-years. Genetic mutation analysis of CRLM, especially KRAS status, has been proposed as a means to guide treatment, as well as identifying patients who can derive the most survival benefit from hepatic resection.Methods
A systematic review of the literature was conducted the PubMed, Embase and Cochrane library through February 8th, 2018. The following algorithm was applied: “(colorectal OR rectal OR colon OR colonic) AND (liver OR hepatic) AND (metastasis OR metastases) AND (gene OR mutation OR KRAS OR BRAF OR SMAD4 OR RAS OR TP53 OR P53 OR APC OR PI3K OR MSI OR EGFR OR MACC1 OR microsatellite).”Results
From the 2404 records retrieved, 78 studies were finally deemed eligible; 47 studies reported mutational data on patients with resectable CRLM, whereas 31 studies reported on patients with unresectable CRLM. Mutational analyses were mostly performed on the CRLM specimen rather than the primary CRC. The vast majority of studies reported on the KRAS mutational status (88.5%, n?=?69/78). Prevalence of KRAS mutations ranged from 25% to 52%. Most studies reported that RAS mutation was a negative prognostic factor for overall (OS) (n?=?24) and recurrence-free (RFS) (n?=?9) survival; a few reports noted no effect of RAS mutational status on OS (n?=?4) or RFS (n?=?6). Twelve studies reported on BRAF mutations with a prevalence of BRAF mutation ranging from 0 to 9.1% in resected CRLM specimens. BRAF mutation was strongly associated with a worse prognosis. TP53 and PIK3CA gene mutations did not affect long-term outcomes.Conclusions
The biological status of each tumor provides the basis for individualized cancer therapeutics. Data on the mutational status on CRLM should be a part of multidisciplinary discussions to help inform the therapeutic approach, type of chemotherapy, as well as timing and approach of surgical resection. 相似文献13.

Objective
To assess the effectiveness of prolonged perioperative thoracic epidural analgesia (PEA) on long term survival of patients who underwent a complete cytoreductive surgery (CRS) and hyperthermic intraperitoneal chemotherapy (HIPEC) for colorectal peritoneal metastases (CPM).Background
Grade III-IV morbidity affects long term outcomes after CRS and HIPEC. As compared with opioid administered via patient-controlled analgesia (PCA), PEA reduces morbidity.Method
From 2005 to 2016, 150 patients underwent CRS plus HIPEC with or without prolonged PEA. Clinical data and outcomes collected from prospective database were analyzed. Survival was assessed in terms of analgesic method using Kaplan-Meier plots and a propensity score.Results
Patients ‘characteristics of 59 patients in PCA group were comparable to those of 91 patients in PEA group, except for age, ASA score and fluid requirements, significantly more important in PEA group. Grade III-IV morbidity was 62.7% in PCA group compared with 36.3% in PEA group (p = 0.0015). Median overall survival (OS) of PEA group was 54.7 months compared to 39.5 months in PCA group (p = 0.0078). When adjusted on the covariates, using the propensity score, the PEA significantly improves OS [HR 0.40 (95% CI: 0.28–0.56)] (p < 0.0001) and disease free survival (DFS) [HR 0.61 (95% CI: 0.45–0.81] (p < 0.0007)Conclusions
In this retrospective study of patients who underwent a complete CRS and HIPEC for colorectal peritoneal metastases, the perioperative thoracic epidural analgesia prolonged for over 72 h reduced significantly the grade III-IV morbidity and may improve OS and DFS. 相似文献14.

Background
The C-C motif chemokine ligand 5/C-C motif chemokine receptor 5 (CCL5/CCR5) pathway has been shown to induce endothelial progenitor cell migration, resulting in increased vascular endothelial growth factor A expression. We hypothesized that genetic polymorphisms in the CCL5/CCR5 pathway predict efficacy and toxicity in patients with metastatic colorectal cancer (mCRC) treated with regorafenib.Patients and Methods
We analyzed genomic DNA extracted from 229 tumor samples from 2 different cohorts of patients who received regorafenib: an evaluation cohort of 79 Japanese patients and a validation cohort of 150 Italian patients. Single nucleotide polymorphisms of CCL5/CCR5 pathway-related genes were analyzed by PCR-based direct sequencing.Results
CCL4 rs1634517 and CCL3 rs1130371 were associated with progression-free survival in the evaluation cohort (hazard ratio [HR] 1.54, P = .043; HR 1.48, P = .064), and progression-free survival (HR 1.74, P < .001; HR 1.66, P = .002) and overall survival (HR 1.65, P = .004; HR 1.65, P = .004) in the validation cohort. The allelic frequencies of CCL5 single nucleotide polymorphisms varied between the evaluation and validation cohorts (G/G variant in rs2280789, 21.5% vs. 1.3%, P < .001; T/T variant in rs3817655, 22.8% vs. 2.7%, P < .001). In the evaluation cohort, patients with the G/G variant in rs2280789 had a higher incidence of grade 3+ hand–foot skin reaction compared to any A allele (53% vs. 27%, P = .078), and similarly to the T/T variant in rs3817655 compared to any A allele (56% vs. 26%, P = .026).Conclusion
Genetic variants in the CCL5/CCR5 pathway may serve as prognostic markers and may predict severe hand–foot skin reaction in mCRC patients receiving regorafenib therapy. 相似文献15.

Background
The aim of the present study was to search for predictive and prognostic factors in patients with metastatic renal cell carcinoma (mRCC) treated with everolimus among the components of the WNT/β-catenin pathway.Patients and Methods
In a prospective, single-arm, phase II study, patients with mRCC received everolimus (10 mg/d) in a 30-day cycle. We performed a prospectively planned evaluation of the potential biomarkers of the WNT/β-catenin pathway.Results
The serum level of soluble E-cadherin (sE-cadherin) in patients with RCC was significantly greater than that in the controls (71.62 ± 22.28 pg/mL vs. 54.26 ± 10.317 pg/mL; P = .0069). After 2 cycles of everolimus therapy, we observed a significance increase in sE-cadherin (from 71.81 ± 21.18 pg/mL to 77.50 ± 28.212 pg/mL; P = .0151). The Dickkopf-1 protein levels in the study and control groups were not significantly different (P = .2135). The favorable independent predictors for everolimus therapy were normal lactate dehydrogenase level before treatment (hazard ratio [HR], 0.52; 95% confidence interval [CI], 0.28-0.98; P = .0443) and low sE-cadherin level (HR, 0.54; 95% CI, 0.29-0.98; P = .0422). On multivariate analysis, we observed that worse overall survival was seen in patients with a lower regression coefficient of sE-cadherin after 2 cycles of treatment (HR, 2.60; 95% CI, 1.23-5.52; P = .0128), an increased corrected calcium level (HR, 3.09; 95% CI, 1.21-7.88; P = .0180), and an increased lactate dehydrogenase level before treatment (HR, 1.98; 95% CI, 1.02-3.83; P = .0426).Conclusion
WNT/β-catenin component expression in patients with mRCC had no effect on progression-free survival or overall survival. However, we found that the sE-cadherin level might interact with response to everolimus therapy, although confirmation in future studies is needed. 相似文献16.

Purpose
To examine the clinicopathologic characteristics and survival outcomes of different histologic types of triple-negative breast cancer (TNBC).Methods
We used the SEER database to identify patients with TNBC diagnosed between 2010 and 2014. Our analysis focused on the seven most prevalent histologic types. Differences were compared between invasive carcinoma of no special type (NST) and the other six types.Results
Significant differences were observed in age at diagnosis, tumor grade, size, nodal status and treatment. As tumor size increased, the number of positive lymph nodes increased markedly in invasive lobular carcinoma (ILC) and mixed NST and lobular carcinoma (NST-ILC), while in metaplastic carcinoma the number only increased slightly. In multivariate survival analyses, compared with patients with invasive carcinoma NST, breast cancer-specific survival (BCSS) and overall survival (OS) were worse for those with NST-ILC (BCSS: hazard ratio [HR] 1.81, P < .001; OS: HR 1.56, P = .005) or metaplastic carcinoma (BCSS: HR 1.95, P < .001; OS: HR 1.73, P < .001). By contrast, patients with medullary (HR 0.40, P = .010) or apocrine carcinoma (HR 0.27, P = .008) showed better BCSS. Time-dependent receiver operating characteristic (ROC) analyses indicated that T category in ILC and N category in metaplastic carcinoma were of less prognostic value.Conclusions
According to the histologic classification of TNBC, this heterogeneous disease can be divided into several entities with different clinicopathologic features and prognoses. In the era of molecular subtyping of breast cancer, the histologic classification of TNBC is still of considerable clinical significance. 相似文献17.

Background
Primary tumour location has long been debated as a prognostic factor in colorectal cancer patients with liver metastases (CRLM) undergoing liver resection. This retrospective study was conducted to clarify the prognostic value of tumour location after radical hepatectomy for CRLM and its underlying causes.Methods
We retrospectively analysed clinical data from 420 patients with CRLM whom underwent liver resection between January 2002 and December 2015. Right-sided (RS) tumours include tumours located in the cecum, ascending colon, and transverse colon, and left-sided (LS) tumours include those located in the splenic flexure, descending colon, sigmoid colon, and rectum.Results
Both overall survival (OS) and disease-free survival (DFS) were similar between patients with RS and LS primary tumours (5-year OS: 46.5% vs 38.3%, P = 0.699; 5-year DFS: 29.1% vs 22.4%, P = 0.536). Specifically, RAS mutation rate was significantly higher in patients with RS tumours (P = 0.007). Subgroup analysis showed that the RAS mutation on the LS and RS tumours have different prognostic impact for CRLM patients on long-term survival after hepatic resection (RS, OS: P = 0.437, DFS: P = 0.471; LS, OS: P < 0.001, DFS: P = 0.002). The multivariable analysis showed that RAS mutant is an independent factor influencing OS in patients with LS primary tumour only.Conclusions
The site of the primary tumour has no significant impact on the long-term survival in patients with CRLM undergoing radical surgery. However, prognostic value of RAS status differs depending on the site of the primary tumour. 相似文献18.

Background
Most cases of rectal cancer (RC) in our institution are in pathologic stage T3. They are a heterogeneous group but have been classified in a single-stage category. We performed the present study to validate the prognostic significance of the mesorectal extension depth (MED) in T3 RC measured in millimeters beyond the muscularis propria plane.Materials and Methods
We performed a retrospective analysis of 104 patients with T3 RC who had undergone curative surgery after a course of preoperative chemoradiotherapy at a tertiary referral cancer hospital. The patients were grouped by MED (T3a, < 1 mm; T3b, 1-5 mm; T3c > 5-10 mm; and T3d > 10 mm). The clinicopathologic data and disease-free survival were analyzed.Results
The 5-year disease-free survival rate according to the T3 subclassification was 87.5% for those with T3a, 57.9% for T3b, 38.7% for T3c, and 40.3% for those with T3d tumors (P = .050). On univariate and multivariate analysis, the prognostic factors affecting survival were overall recurrence (hazard ratio [HR], 3.670; 95% confidence interval [CI], 1.710-7.837; P = .001), histologic grade (HR, 2.204; 95% CI, 1.156-4.199; P = .016), mesorectal invasion depth (HR, 1.885; 95% CI, 1.164-3.052; P = .010), and lymph node metastasis (HR, 1.211; 95% CI, 1.015-1.444; P = .033).Conclusion
MED is a significant prognostic factor in patients with T3 RC who have undergone neoadjuvant chemoradiotherapy, especially when the MED is > 5 mm. The MED could be as important as other clinicopathologic factors in predicting disease-specific survival. 相似文献19.

Introduction
Numerous trials have examined the prognostic and predictive value of localization of the primary tumor (LPT) in metastastic colorectal cancer, there is limited information about the predictive value of LPT on different maintenance strategies.Materials and Methods
We analyzed progression-free survival (PFS)/overall survival (OS) on maintenance therapy according to LPT and mutational subgroups (BRAF/RAS) in patients from the AIO (Arbeitsgemeinschaft Internistische Onkologie) 0207 trial. Following induction, 471 patients were randomized to fluoropyrimidine (FU)/bevacizumab (Bev), Bev, or no treatment. Data on LPT were available in 414 (91%) patients.Results
A total of 291 patients were left-sided (LPTl, 70%), and 123 were right-sided (LPTr, 30%). The median PFS was 3.9 months for LPTr and 5.3 months for LPTl (P = .11; hazard ratio [HR], 1.19; 95% confidence interval [CI], 0.96-1.48). There was no predictive impact of LPT on the maintenance strategies. The pairwise comparison of treatment arms showed a better PFS for FU/Bev versus no treatment independent from LPT (left, P < .0001; HR, 2.39; 95% CI, 1.73-3.31; right, P = .011; HR, 1.78; 95% CI, 1.14-2.80). Analysis for OS (429 patients) confirmed the strong prognostic impact of LPT (left vs. right: 24.0 vs. 16.7 months; P < .0001; HR, 1.65; 95% CI, 1.32-2.06), but also without major interaction between the LPT and maintenance arms. The strong negative prognostic impact of BRAF mutation was confirmed in right-/left-sided metastastic colorectal cancer, reaching significance in LPTl. In patients with RAS mutational status, the negative prognostic impact of the mutation remains, but its effect is stronger in LPTl (P < .0001).Conclusion
The strong prognostic factor of LPT is confirmed undergoing oxaliplatin/FU/Bev induction therapy, whereas there seems to be no major predictive impact of LPT on different maintenance strategies. 相似文献20.
