Background
The objective of this study was to investigate positive surgical margin (PSM) rates in patients with prostate cancer treated with radical prostatectomy (RP) and assess PSM impact on cancer-specific mortality (CSM).Patients and Methods
Within the Surveillance, Epidemiology, and End Results (SEER) database (2004-2015), we identified men who underwent RP with pathologic T2 or T3a stage. Annual trends of PSM rates were plotted. Subgroups focused on geographic regions, namely the North Central, Northeast, South, and West. Cumulative incidence plots depicted other-cause mortality-adjusted CSM rates. Multivariable competing risks regression models tested the relationship between PSM and CSM. Subgroup analyses focused on pathologic stage, Gleason score, and geographic region.Results
Of 153,329 patients treated with RP, 12.3% (n = 18,935) exhibited PSM. Overall, in pathologic T2 stage and pathologic T3a stage, PSM rates decreased during the study period from 18.7% to 9.7% (P < .001), 15.7% to 7.3% (P < .001), and 39.0% to 18.0% (P < .001), respectively. In subgroup analyses focusing on geographic regions, PSM rates universally decreased. However, the magnitude differed. In multivariable competing risks regression models, PSM rates were associated with higher CSM (hazard ratio, 1.45; P < .001). However, geographic regions failed to reach independent predictor status. Insufficient information about PSM focality, length, and associated Gleason score represent important limitations.Conclusion
It is encouraging that PSM rates decreased during the study period, even after stratification according to tumor stage. PSM decreased within the 4 examined geographic regions. However, the rate of decrease varied in magnitude, but geographic regions did not represent an independent predictor of PSM. 相似文献2.

Background
We analyzed the trends in presentation of squamous cell carcinoma (SCC) of the penis and determined the socioeconomic predictors for locally advanced (cT3-cT4) disease in the United States.Patient and Methods
The National Cancer Database was queried for patients with clinically nonmetastatic penile SCC and staging available from 1998 to 2012. Temporal trends per tumor stage were evaluated, and a multivariable logistic regression model was used to identify predictors for advanced presentation during the study period.Results
A total of 5767 patients with stage ≤ T1-T2 (n = 5423) and T3-T4 (n = 344) disease were identified. Increasing trends were noted in all stages of penile SCC with a greater proportion of advanced cases over time (P = .001). Significant predictors of advanced presentation were age > 55 years, the presence of comorbidities, and Medicaid or no insurance (P < .05 for all).Conclusion
More penile SCC is being detected in the United States. Our results have demonstrated older age, presence of comorbidities, and Medicaid or no insurance as potential barriers to early access of care in the male population. Understanding the current socioeconomic gaps could help guide targeted interventions in vulnerable populations. 相似文献3.

Purpose
The 8th edition of the American Joint Committee on Cancer (AJCC) breast cancer staging system requires histologic grade (GR), estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), and stage (assessed by the tumor, node, metastasis classification system). For T1-2 N0, ER+/HER2? tumors, if the 21-gene expression assay is ordered and Oncotype DX (ODX) recurrence score (RS) is 0 to 10, the stage is IA. The purpose of this study was to determine the impact of the ODXRS on staging ER+/HER2? tumors.Materials and Methods
This is a retrospective review of ER+/HER2? invasive breast cancer (BC) with ODXRS results from 2 institutions (n = 816) between 2006 and 2018. Stage based on the AJCC 7th and 8th editions, and stage using the 8th edition with and without ODXRS were compared. Significant associations among pathologic parameters and ODX risk groups were determined. Clinical histories were reviewed.Results
Nearly half of the patients (43%) had a change in BC stage using the new staging system. Only 4 patients changed stage as a direct result of ODXRS. Influence of ODXRS on staging is limited to T2N0 tumors that are either GR 3 and strongly ER+ and PR+ or GR 1-2 and ER+/PR?. Sixty-one percent of cases of recurrence (11/18) were downstaged using the new staging system.Conclusion
ODXRS has little influence on staging, thus supporting the view of the AJCC 8th edition expert panel that ODX is not required for staging. Downstaging of more than half of cases of recurrence suggests that continued refinement of the staging system, as proposed by the expert panel, could be beneficial in this subgroup of patients. 相似文献4.

Introduction
Stereotactic body radiation therapy (SBRT) is commonly used to treat nonsurgical patients with early-stage NSCLC. There are no prospective data on the role of adjuvant chemotherapy in this setting.Methods
Patients (≥18 years) diagnosed with clinical stages I-II NSCLC from 2004 to 2013 were identified using the National Cancer Database (n = 11,836). The Kaplan-Meier method was used to estimate overall survival (OS) distributions and the log-rank test was used to compare distributions by treatment strategy. Clinical stages I and II were subdivided according to the TNM staging and log-rank tests was used to compare survival distributions by treatment strategy within each subgroup.Results
In patients with T2bN0, median OS in the SBRT alone and SBRT plus adjuvant chemotherapy groups were 16.5 months versus 24.2 months, respectively (95% confidence interval [CI]: 14.1–20.1 months and 18.8–33.3 months, respectively; p < .001); whereas for T3N0, median OS times were 13 months and 20.1 months, respectively (95% CI: 11.7–14.5 mohths and 17.7–21.9 months, respectively; p < .001). For tumors 4 cm or larger and node-negative disease, median OS was 15.9 months in the SBRT-alone group, and 19 months in the SBRT-plus-chemotherapy group (95% CI: 15.1–16.8 months and 17.9–20.8 months, respectively; p < .001). For patients with tumors less than 4 cm and node-negative disease, the median OS was 28.5 months in the SBRT-alone group and 24.3 months in the SBRT-plus-chemotherapy group (95% CI: 27.4–29.4 months and 22.8–26.1 months, respectively; p < .001).Conclusions
SBRT followed by adjuvant chemotherapy was associated with improved OS in comparison with SBRT alone in patients with T greater than or equal to 4 cm, similar to that seen after surgery. 相似文献5.

Background
To investigate the clinical outcomes in patients with high-risk prostate cancer (PCa) treated with neoadjuvant chemohormonal therapy (NCHT) before radical prostatectomy (RP).Patients and Methods
Our NCHT protocol involved complete androgen blockade followed by 6 cycles of docetaxel (30 mg/m2) plus estramustine phosphate (560 mg). NCHT was provided to 60 patients with PCa before RP, and we compared the clinical and pathologic outcomes with those of 349 patients with high-risk PCa who underwent RP alone using propensity score matching. The data for those who underwent RP alone were obtained from the Michinoku Japan Urological Cancer Study Group database.Results
In the NCHT group, 10.0% experienced pathologic complete response, 3.3% had positive surgical margins, and 13.3% developed severe complications (Clavien-Dindo grade III or higher) after RP. The median follow-up duration was 42.5 months, and the 5-year biochemical recurrence (BCR)-free survival was 60.1%. In multivariate analysis, pN+ was an independent prognostic factor for BCR (hazard ratio = 5.251, 95%CI 1.300-21.201; P = .020). In propensity score matching, the BCR rate in the NCHT group was significantly lower than that in the RP alone group (P = .021). In subgroup analyses, the BCR rate in patients with a single high-risk factor was significantly lower in the NCHT group than in the RP-alone group (P = .027).Conclusion
NCHT before RP can reduce the risk of BCR in patients with high-risk PCa, particularly if a single high-risk factor is present. However, the potential for perioperative complications should be considered. 相似文献6.

Background
In the Surveillance, Epidemiology, and End Results population-based data, the survival curves reversed between T4N0 (stages IIB or IIC) and T1-2N1 (stage IIIA) in rectal cancer. However, T4N0 had a higher stage than T1-2N1 in the current colorectal staging system.Patients and Methods
We analyzed 1804 patients with rectal cancer who were treated with preoperative chemoradiotherapy and curative surgery. We grouped patients by pathologic stage, and recurrence-free survival (RFS) and overall survival rates were calculated and compared for each stage. We evaluated prognostic factors that influenced recurrence and survival.Results
In the recurrence and survival analysis, 3-year RFS rates were 95.9% for ypStage 0, 94.0% for ypStage I, 78.9% for ypStage IIA, 55.8% for ypStage IIB/C, 80.2% for ypStage IIIA, 64.6% for ypStage IIIB, and 44.9% for ypStage IIIC. Patients with ypStage IIB/C showed significantly worse RFS (P = .004) than did those with ypStage IIIA. The ypStage IIB/C group showed significantly higher rates of both locoregional recurrence (24.3% vs. 5.5%; P = .02) and distant metastasis (31.6% vs. 17.1%; P = .048) than did the ypStage IIIA group. Compared with ypStage IIIA, ypStage IIB/C showed significantly higher pre-chemoradiotherapy carcinoembryonic antigen (P = .004), circumferential radial margin involvement (P = .001), and positive perineural invasion (P = .014).Conclusion
Patients with rectal cancer staged ypT4N0 were associated with higher locoregional recurrence and distant metastasis rates than those staged ypT1-2N1 in the current staging system. 相似文献7.

Background
Inflammation and infections have been associated with prostate cancer progression. We assessed whether elevated serum cytokines or T. vaginalis seropositivity at the time of diagnosis was associated with higher grade or lethal prostate cancer.Patients and Methods
Men with localized or metastatic prostate cancer were included in this study. Cytokine serum levels including interleukin (IL)-1α, IL-1β, IL-2, IL-6, IL-8, monocyte chemotactic protein 1 (CCL-2), tumor necrosis factor α, and growth-regulated oncogene α (CXCL-1) using a multiplex enzyme-linked immunosorbent assay and T. vaginalis serology were measured in blood samples at diagnosis.Results
A total of 324 patients were identified at time of localized disease and 118 at time of metastatic disease. Of the 189 patients with localized disease and clinical follow-up data (median, 73 months), 28 developed lethal disease. There was no association between circulating cytokine levels above median concentrations nor T. vaginalis seropositivity and risk of intermediate- to high-risk or lethal prostate cancer.Conclusion
Higher levels of serum cytokine levels and T. vaginalis seropositivity at diagnosis are not associated with high-grade or lethal prostate cancer and do not aid risk stratification of localized prostate cancer. 相似文献8.

Purpose
To determine a subset of women who could undergo ovary-sparing radical cystectomy (OSRC) for bladder cancer without compromising oncologic safety.Patients and Methods
A retrospective review was performed of 164 consecutive women who underwent cystectomy at a single tertiary-care center from 1997 to 2018. Clinicopathologic and preoperative radiographic data were reviewed. Univariable and multivariable logistic regression models adjusting for pathologic stage, lymphovascular invasion (LVI), and carcinomain-situ were performed to evaluate the risk of ovarian and reproductive organ (RO) involvement.Results
A total of 123 women with a median age of 71 years underwent radical cystectomy (RC) with removal of ROs for primary bladder cancer. Nineteen women (15%) had RO involvement by bladder cancer, and 5 of them (4%) were specifically found to have ovarian involvement. Patients with ovarian involvement of bladder cancer had more locally advanced disease (P = .01), LVI (P = .003) and positive margins (P = .003). On multivariable logistic regression, ≥ pT3 (odds ratio = 10.2; 95% confidence interval, 2.0-51.6; P = .005) and LVI (odds ratio = 3.9; 95% confidence interval, 1.1-14.2; P = .037) were associated with increased risk of RO involvement. Among 15 patients excluded for having a nonbladder primary malignancy, a third had RO involvement, and 2 (13%) had ovarian metastases. No women in our cohort had a primary ovarian malignancy detected at the time of RC.Conclusion
Women with ovarian involvement by malignancy at the time of RC either had locally advanced disease with LVI or a non-bladder primary malignancy. The risk of incompletely resecting the primary malignancy would be rare if OSRC was performed on women with organ-confined (≤T2) urothelial carcinoma. 相似文献9.

Introduction
Long-term data on outcomes of operable stage III NSCLC are scarce.Methods
Individual patient data from 368 patients enrolled in one phase III and two phase II trials were pooled and outcomes after applying the eighth (denoted with an asterisk [*]) versus the sixth TNM staging edition were compared. Patients were treated with either preoperative radiotherapy following 3 cycles of induction chemotherapy (trimodal) or neoadjuvant chemotherapy alone (bimodal).Results
With the sixth version, the 5- and 10-year survival rates were 38% and 28% for stage IIIA, respectively, and 36% and 24% for stage IIIB, respectively. Factors associated with improved 5-year overall survival were younger age, R0 resection, and pathologic complete remission (pCR) (p = 0.043, p < 0.001 and p = 0.009). With the eighth TNM staging version, 162 patients were moved from stage IIIA to IIIB*. The 5- and 10-year survival rates were 41% and 29% for stage IIIA*, respectively, and 35% and 27% for stage IIIB* patients, respectively. There was no difference in the bi- versus trimodal group with regard to median overall survival (28 months [95% confidence interval (CI): 21–39 months] and 37 months [95% CI: 24–51 months], p = 0.9) and event-free survival (12 months [95% CI: 9–15 months] versus 13 months [95% CI: 10–22 months], p = 0.71).Conclusions
We showed favorable 10-year survival rates of 29% and 27% in stage IIIA* and IIIB*, respectively. Younger age, R0 resection, and pathologic complete response were associated with improved long-term survival. Outcomes using the sixth versus eighth edition of the TNM classification were similar in operable stage III NSCLC. 相似文献10.

Background
In colorectal cancer liver metastases (CRCLM), bevacizumab-based neoadjuvant strategies provide increased pathologic response. We aimed at assessing the activity of perioperative capecitabine, oxaliplatin, irinotecan, and bevacizumab (COI-B regimen) in patients with potentially resectable CRCLM, and investigating biomarkers for early prediction of pathologic response.Patients and Methods
This was a single-center phase II study enrolling patients with liver-limited, borderline resectable disease and/or high-risk features. Patients received 5 preoperative and 4 postoperative cycles of biweekly COI-B (irinotecan 180 mg/m2 and bevacizumab 5 mg/Kg on day 1, oxaliplatin 85 mg/m2 on day 2, and capecitabine 1000 mg/m2 twice a day on days 2 to 6). The primary endpoint was pathologic response rate in the intention-to-treat population. A Simon 2-stage design was adopted to detect an increase from 30% to 50% with a power of 90%. Dynamic imaging biomarkers (early tumor shrinkage [ETS], deepness of response, maximum standardized uptake volume [SUVmax]/regression index) and next generation sequencing data were explored as surrogates.Results
From June 2013 to March 2017, 46 patients were enrolled. Pathologic response was achieved in 63% patients (endpoint met), and responders achieved significantly better survival outcomes with respect to non-responders. The most frequent grade 3/4 adverse events were diarrhea and neutropenia (8.7%) in the preoperative phase and thromboembolic events (5.9%) in the postoperative phase. ETS and lower SUV-2 were significantly associated with pathologic response.Conclusion
The COI-B regimen is a feasible and highly active perioperative strategy in patients with molecularly unselected, potentially resectable CRCLM. ETS and SUV-2 have a promising role as imaging-based biomarkers for pathologic response. 相似文献11.

Background
Cardiovascular events (CVEs) have been observed in patients with chronic myeloid leukemia treated with second-generation tyrosine kinase inhibitors.Patients and Methods
We retrospectively evaluated the incidence of CVEs on 233 consecutive patients with chronic myeloid leukemia, of which 116 were treated with imatinib, 75 with dasatinib, and 42 with nilotinib. The median follow-up was 2047, 1712, and 1773 days, respectively.Results
The cumulative incidence of CVEs was 4.29%. Three events occurred during dasatinib treatment, 6 during nilotinib treatment, and none during imatinib treatment (P ≤ .001). Arterial occlusive events occurred in 2 (2.6%) of 75 patients treated with dasatinib and in 6 (14.2%) of 42 patients treated with nilotinib (P ≤ .001). Furthermore, all of them occurred in patients with high-risk (n = 2) and very high-risk (n = 6) cardiovascular risk, contributing to 4.3% of mortality.Conclusion
CVEs were more frequent in patients treated with second-generation tyrosine kinase inhibitors. Arterial occlusive events were more frequent in patients treated with nilotinib, with high and very high cardiovascular risk. 相似文献12.

Background
Chromophobe renal cell carcinoma (chRCC) is known as an indolent tumor; however, mortality still occurs. We sought to determine the clinicopathologic and genomic factors associated with aggressive chRCC.Patients and Methods
Two different datasets were used to identify patients with clinical stage III and IV chRCC. Eighteen patients from The Cancer Genome Atlas (TCGA) database and 1693 patients from the American College of Surgeons National Cancer Database (NCDB) were used for analysis. From the TCGA, RNA-Seq expression analysis of 18,745 genes was conducted between the recurrent (n = 5; 27.8%) and nonrecurrent patients (n = 13; 72.2%). Biological significance was identified via pathway enrichment and gene function analyses. From the NCDB, Cox proportion hazards regression models were used to identify variables associated with overall survival (OS) at a median follow-up of 41.4 months.Results
Between the 2 groups, 2182 genes were differentially expressed. The most commonly overexpressed pathways were neuroactive ligand-receptor interactions and cytokine-cytokine receptor interactions. The most activated gene functions were cellular, metabolic, and multicellular organismal processes. In the NCDB, multivariable analysis, age (hazard ratio [HR], 1.04; 95% confidence interval [CI], 1.03-1.05; P < .001), TNM stage IV versus III (HR, 3.86; 95% CI, 2.98-5.00; P < .001), and positive surgical margin (HR, 1.68; 95% CI, 1.45-1.96; P < .001) were associated with worse OS at a median follow-up of 41.4 months. Five-year OS was significantly lower for stage IV patients compared with stage III patients (80.0% vs. 29.9%; P < .001).Conclusions
Patients with recurrent chRCC demonstrated a differential gene expression of specific biochemical pathways. Clinical parameters associated with worse OS included age, stage, and positive surgical margin. 相似文献13.

Background
We questioned whether the National Comprehensive Cancer Network recommendations for brain magnetic resonance imaging (MRI) for patients with stage ≥ IB non–small-cell lung cancer (NSCLC) was high-yield compared with American College of Clinical Pharmacy and National Institute for Health and Care Excellence guidelines recommending stage III and above NSCLC. We present the prevalence and factors predictive of asymptomatic brain metastases at diagnosis in patients with NSCLC without extracranial metastases.Materials and Methods
A retrospective analysis of 193 consecutive, treatment-naïve patients with NSCLC diagnosed between January 2010 and August 2015 was performed. Exclusion criteria included no brain MRI staging, symptomatic brain metastases, or stage IV based on extracranial disease. Univariate and multivariate logistic regression was performed.Results
The patient characteristics include median age of 65 years (range, 36-90 years), 51% adenocarcinoma/36% squamous carcinoma, and pre-MRI stage grouping of 31% I, 22% II, 34% IIIA, and 13% IIIB. The overall prevalence of brain metastases was 5.7% (n = 11). One (2.4%) stage IA and 1 (5.6%) stage IB patient had asymptomatic brain metastases at diagnosis, both were adenocarcinomas. On univariate analysis, increasing lymph nodal stage (P = .02), lymph nodal size > 2 cm (P = .009), multi-lymph nodal N1/N2 station involvement (P = .027), and overall stage (P = .005) were associated with asymptomatic brain metastases. On multivariate analysis, increasing lymph nodal size remained significant (odds ratio, 1.545; P = .009).Conclusion
Our series shows a 5.7% rate of asymptomatic brain metastasis for patients with stage I to III NSCLC. Increasing lymph nodal size was the only predictor of asymptomatic brain metastases, suggesting over-utilization of MRI in early-stage disease, especially in lymph node-negative patients with NSCLC. Future efforts will explore the utility of baseline MRI in lymph node-positive stage II and all stage IIIA patients. 相似文献15.

Introduction
We evaluated differences in the clinicopathologic characteristics and prognosis based on the presence of ground glass opacity (GGO) components in small-sized lung adenocarcinoma.Methods
We retrospectively investigated 634 lung adenocarcinomas classed as c-stage IA in the eighth edition TNM classification. Staging was defined according to the solid component size measured by thin-section computed tomography. All tumors were grouped into either a GGO or solid group, based on the presence of a GGO component.Results
Of the cases, 215 (34%) were classed as c-stage IA1 (T1mi: 88, T1a-GGO: 102, T1a-solid: 25), 255 (40%) as c-stage IA2 (T1b-GGO: 122, T1b-solid: 133), and 164 (26%) as c-stage IA3 (T1c-GGO: 44, T1c-solid: 120). Among the 546 c-stage IA cases excluding the T1mi lesions, Cox regression analysis revealed that presence of GGO was an independently significant prognosticator (p = 0.024). The result was validated in 494 c-stage IA lung adenocarcinomas with a nonpredominant GGO component, showing the presence of GGO as a significant prognosticator (p = 0.048). When we evaluated the prognostic impact of GGO presence in each clinical stage, the 5-year overall survival (OS) was significantly different between the GGO and solid groups (IA1: 97.8% versus 86.6%, p = 0.026; IA2: 89.3% versus 75.2%, p = 0.007; IA3: 88.5% versus 62.3%, p = 0.003). Furthermore, the 5-year overall survival b was distinct in parallel similar pathologic findings when comparing a lepidic versus an invasive component (IA1: 97.9% versus 85.6%, p = 0.031; IA2: 86.1% versus 69.4%, p = 0.007; IA3: 77.5% versus 55.8%, p < 0.001).Conclusions
Clinicopathologic and oncologic outcomes were disparate based on the presence of a GGO component in the eighth edition TNM classification of c-stage IA lung adenocarcinoma. 相似文献16.

Background
Breast cancer metastases to an ipsilateral supraclavicular lymph node is assigned a N3 status in the TNM system and thus classified as stage III disease in the American Joint Commission on Cancer staging manual. Breast cancer metastatic to contralateral axillary lymph node (CAM) without metastases to any other distant organ is currently assigned M1 status (stage IV) instead of N3 (stage III).Patients and Methods
We retrospectively reviewed the medical records of breast cancer patients diagnosed with CAM for their clinical presentation, pathologic diagnoses, treatment, and follow-up data. Patients who had distant metastases at the time of CAM diagnosis were excluded from the study.Results
We report 12 breast cancer patients who developed CAM but no evidence of metastases in any other distant organ documented with extensive imaging workup. Imaging studies and thorough pathologic evaluation of the prophylactic total mastectomy specimen did not reveal a primary in the breast to account for the metastases in the axillary node.Conclusion
Findings of our study as well as previous studies support that lymph node metastases in the contralateral axilla represents a locoregional spread of the tumor from the index breast via lymphatics rather than hematogenous spread. Therefore, isolated CAM in breast cancer patients should not be classified as stage IV disease. 相似文献17.

Background
There are no validated markers that predict response or resistance in patients with metastatic clear-cell renal cell carcinoma (mccRCC) treated with vascular endothelial growth factor receptor tyrosine kinase inhibitors such as sunitinib and pazopanib. Recently, single nucleotide polymorphism (SNP) rs2981582 in Fibroblast Growth Factor Receptor 2 (FGFR2) was found to be associated with clinical outcome in patients with mccRCC treated with pazopanib and sunitinib. We aimed to validate these findings in patients treated with sunitinib.Materials and Methods
Germline DNA was collected in patients with mccRCC starting first-line systemic therapy with sunitinib. SNP rs2981582 in FGFR2 C>T was genotyped. Association of the genotype with response rate, tumor shrinkage, median progression-free survival (mPFS), and median overall survival (mOS) was studied.Results
We collected clinical data from 154 patients with available germline DNA. Baseline prognostic markers were well-balanced between both subgroups. Patients with the TT genotype had a poorer outcome compared with patients with the CT/CC genotype. The median shrinkage of selected tumor target lesions during treatment with sunitinib was ?16% versus ?31% (P = .002), mPFS was 8 versus 15 months (P = .0007), and mOS was 22 versus 33 months (P = .04), respectively. On multivariate analysis, rs2981582 remained an independent predictor of PFS (hazard ratio, 2.858; 95% confidence interval, 1.659-4.923; P < .0001) and OS (hazard ratio, 1.795; 95% confidence interval, 1.003-3.212; P = .049).Conclusion
Polymorphism rs2981582 in FGFR2 is correlated to PFS and OS in patients with mccRCC treated with sunitinib. Prospective validation of the impact of this SNP is warranted. 相似文献18.

Introduction
The TNM classification for lung cancer, originally designed for NSCLC, is applied to staging of bronchopulmonary carcinoid tumors. The validity of the eighth edition of the staging system for carcinoid tumors has not been assessed. In this study, we evaluated its prognostic accuracy by using data from a large national population-based cancer registry.Methods
Patients with typical and atypical bronchopulmonary carcinoids diagnosed between 2000 and 2013 were identified from the National Cancer Institute’s Surveillance, Epidemiology and End Results registry. We used competing risks analysis to compare 10-year disease-specific survival (DSS) across stages.Results
Overall, 4645 patients with bronchopulmonary carcinoid tumors were identified. Worsening DSS with increasing TNM status and stage was demonstrated across both typical and atypical carcinoids, with overlaps between adjacent subcategories. The combined stages (I versus II, II versus III, and III versus IV) showed greater separation in DSS despite persistent overlaps between groups. For typical carcinoids, we found decreased DSS for stages II, III, and IV, with hazard ratios of 3.8 (95% confidence interval [CI]: 2.6–5.6), 4.3 (95% CI: 3.0–6.1), and 9.0 (95% CI: 6.1–13.1), respectively, compared with stage I.Conclusion
The combined stage categories of the eighth edition of the TNM staging system provide useful information on outcomes for typical and atypical carcinoids. However, persistent overlaps in combined stage and subcategories of the staging system limit the usefulness of the TNM staging system, particularly in intermediate stages. These limitations suggest the need for future further study and refinement. 相似文献19.

Introduction
Chronic lymphocytic leukemia (CLL) is the most common lymphoproliferative disorder worldwide. Although thoracic complications are frequent in CLL, only limited data exists regarding these complications. Pleural, parenchymal, and airway disease may occur owing to CLL itself, treatment-related adverse events, typical or opportunistic infections, or from preexisting comorbidities. The etiology of parenchymal infiltrates is often attributed to pneumonia and can be difficult to properly identify without a diagnostic procedure.Patients and Methods
We conducted a retrospective chart review of patients admitted from 2000 through 2016 with a diagnosis of CLL and abnormal radiography that underwent a bronchoscopy with biopsy, surgical lung biopsy, or transthoracic biopsies for nonresolving infiltrates after a course of antibiotics. We described the incidence of bronchopulmonary leukemic infiltrates (BPLI), describe other diagnosis achieved by the biopsy, and also describe the pathologic findings associated with BPLI in these patients.Results
There were 111 procedures performed on 98 patients that yielded a diagnosis in 82 patients. In 16 patients, no histologic or pathologic diagnosis was identified after the biopsy. BPLI was diagnosed in 32 (39%) cases. In 27 (85%) of 32 cases, the biopsies returned with only BPLI owing to CLL (without inflammation), whereas 5 (15%) of 32 cases showed concomitant acute or chronic inflammation.Conclusion
Direct infiltration by leukemic cells may cause pulmonary symptoms and signs indistinguishable from infection. Biopsy is necessary to establish a definitive diagnosis, and physicians caring for these patients, including pathologists, should be aware of the clinicopathologic picture of BPLI to render an informative diagnosis. 相似文献20.
