BACKGROUND
Recurrent/ metastatic squamous cell carcinoma of head and neck (R/M SCCNH) is still a difficult-to-treat disease with poor clinical outcomes and limited treatment choices. In view of locoregional recurrent versus distant metastatic SCCHN, the therapeutic efficacy of cetuximab-containing regimen and relevant prognostic factors for these two groups may be different. Thus, the aim of this study was to explore the treatment outcomes of cetuximab-containing regimen in locoregional recurrent and distant metastatic SCCHN groups, and to identify clinical factors correlated with better survival outcomes.
METHODS
From 2016 to 2020, patients with R/M SCCHN who received cetuximab-containing regimen in our institute were enrolled in this study. Clinical outcomes including overall survival (OS), progression-free survival (PFS), objective response rate (ORR) and disease control rate (DCR) were evaluated in both locoregional recurrence and distant metastasis groups. Exploratory analysis were conducted to investigate major clinical features associated with better outcomes.
RESULTS
A total of 107 patients with locoregional recurrent SCCHN (N = 66) and distant metastatic SCCNH (N = 41) who received cetuximab-containing regimen were enrolled in this retrospective study. Patients with oral cavity cancer and patients with disease recurrence within 6 months after radiation therapy were significantly increased in locoregional recurrence group. The median OS (15.6 vs. 9.7 months, P = 0.004) and PFS (5.8 months vs. 4.2 months, P = 0.008) were longer in locoregional recurrence group than in distant metastasis group. In multivariate analysis of clinical features, locoregional recurrence was still an important risk factor associated with better OS (Hazzard ratio (HR) 0.64, p = 0.06) and PFS (HR 0.67, p = 0.075). In addition, a trend of favorable disease control rate (DCR; 62.5% vs. 45.0%, p = 0.056) was noted in locoregional recurrence group. In locoregional recurrence group, prior salvage surgery was associated with longer OS (HR = 0.24, P = 0.008) and PFS (HR = 0.30, P = 0.005).
CONCLUSION
SCCHN with locoregional recurrence is associated with better disease control and survival outcomes comparing to distant metastatic SCCHN when treated with cetuximab-containing regimen. Salvage surgery for locoregional recurrence may further improves clinical outcome.

Background: Curatively treated bronchial carcinoid tumors have a relatively low metastatic potential. Gradation into typical (TC) and atypical carcinoid (AC) is limited in terms of prognostic value, resulting in yearly follow-up of all patients. We examined the additional prognostic value of novel immunohistochemical (IHC) markers to current gradation of carcinoids. Methods: A retrospective single-institution cohort study was performed on 171 patients with pathologically diagnosed bronchial carcinoid (median follow-up: 66 months). The risk of developing distant metastases based on histopathological characteristics (Ki-67, p16, Rb, OTP, CD44, and tumor diameter) was evaluated using multivariate regression analysis and the Kaplan−Meier method. Results: Of 171 patients, seven (4%) had disseminated disease at presentation, and 164 (96%) received curative-intent treatment with either endobronchial treatment (EBT) (n = 61, 36%) or surgery (n = 103, 60%). Among the 164 patients, 13 developed metastases at follow-up of 81 months (IQR 45−162). Univariate analysis showed that Ki-67, mitotic index, OTP, CD44, and tumor diameter were associated with development of distant metastases. Multivariate analysis showed that mitotic count, Ki-67, and OTP were independent risk factors for development of distant metastases. Using a 5% cutoff for Ki-67, Kaplan−Meier analysis showed that the risk of distant metastasis development was significantly associated with the number of risk predictors (AC, Ki-67 ≥ 5%, and loss of OTP or CD44) (p < 0.0001). Six out of seven patients (86%) with all three positive risk factors developed distant metastasis. Conclusions: Mitotic count, proliferation index, and OTP IHC were independent predictors of dissemination at follow-up. In addition to the widely used carcinoid classification, a comprehensive analysis of histopathological variables including Ki-67, OTP, and CD44 could assist in the determination of distant metastasis risks of bronchial carcinoids.

BACKGROUND
Studies have demonstrated worse breast cancer-specific mortality with older age, despite an increasing risk of dying from other causes due to comorbidity (competing mortality). However, findings on the association between older age and recurrence risk are inconsistent. The aim of this study was to assess incidences of locoregional and distant recurrence by age, taking competing mortality into account.
MATERIALS AND METHODS
Patients surgically treated for nonmetastasized breast cancer between 2003 and 2009 were selected from The Netherlands Cancer Registry. Cumulative incidences of recurrence were calculated considering death without distant recurrence as competing event. Fine and Gray analyses were performed to characterize the impact of age (70-74 [reference group], 75-79, and ≥80 years) on recurrence risk.
RESULTS
A total of 18,419 patients were included. Nine-year cumulative incidences of locoregional recurrence were 2.5%, 3.1%, and 2.9% in patients aged 70-74, 75-79, and ≥80 years, and 9-year cumulative incidences of distant recurrence were 10.9%, 15.9%, and 12.7%, respectively. After adjustment for tumor and treatment characteristics, age was not associated with locoregional recurrence risk. For distant recurrence, patients aged 75-79 years remained at higher risk after adjustment for tumor and treatment characteristics (75-79 years subdistribution hazard ratio [sHR], 1.25; 95% confidence interval [CI], 1.11-1.41; ≥80 years sHR, 1.03; 95% CI, 0.91-1.17).
CONCLUSION
Patients aged 75-79 years had a higher risk of distant recurrence than patients aged 70-74 years, despite the higher competing mortality. Individualizing treatment by using prediction tools that include competing mortality could improve outcome for older patients with breast cancer.
IMPLICATIONS FOR PRACTICE
In this population-based study of 18,419 surgically treated patients aged 70 years or older, patients aged 75-79 years were at higher risk of distant recurrence than were patients aged 70-74 years. This finding suggests that patients in this age category are undertreated. In contrast, it was also demonstrated that the risk of dying without a recurrence strongly increases with age, and patients with a high competing mortality risk are easily overtreated. To identify older patients who may benefit from more treatment, clinicians should therefore take competing mortality risk into account. Prediction tools could facilitate this and thereby improve treatment strategy.

BACKGROUND
Small intestine cancer (SIC) is difficult to diagnose early and presents a poor prognosis due to distant metastasis. This study aimed to develop nomograms for diagnosing and assessing the prognosis of SIC with distant metastasis.
METHODS
Patients diagnosed with SIC between 2010 and 2015 were included from the Surveillance, Epidemiology and End Results database. Univariate and multifactor analysis determined independent risk factors for distant metastasis and prognostic factors for overall and cancer-specific survival. We then constructed the corresponding three nomograms and assessed the diagnostic accuracy of the nomograms by net reclassification improvement, receiver operating characteristic curves and calibration curves, assessed the clinical utility by decision curve analysis.
RESULTS
The cohort consisted of 6697 patients, of whom 1299 had distant metastasis at diagnosis. Tstage, Nstage, age, tumor size, grade, and histological type were independent risk factors for distant metastasis. Age, histological type, T stage, N stage, grade, tumor size, whether receiving surgery, number of lymph nodes removed, and the presence of bone or lung metastases were predictors of both overall survival and cancer-specific survival. The nomograms showed excellent accuracy in predicting distant metastasis and prognosis.
CONCLUSION
Nomograms were developed and validated for SIC patients with distant metastasis, aiding physicians in making rational and personalized clinical decisions.

AIMS
This study aimed to investigate the distant metastasis pattern from newly diagnosed colorectal cancer (CRC) and also construct and validate a prognostic nomogram to predict both overall survival (OS) and cancer-specific survival (CSS) of CRC patients with distant metastases.
METHODS
Primary CRC patients who were initially diagnosed from 2010 to 2016 in the SEER database were included in the analysis. The independent risk factors affecting the OS, CSS, all-cause mortality, and CRC-specific mortality of the patients were screened by the Cox regression and Fine-Gray competitive risk model. The nomogram models were constructed to predict the OS and CSS of the patients. The reliability and accuracy of the prediction model were evaluated by consistency index (C-index) and calibration curve. The gene chip GSE41258 was downloaded from the GEO database, and differentially expressed genes (DEGs) were screened by the GEO2R online tool ( < 0.05, |logFC|>1.5). The Kyoto Encyclopedia of Genes and Genomes (KEGG) Pathway and Gene Ontology (GO) annotation and String website were used for enrichment analysis and protein-protein interaction (PPI) analysis of DEGs, respectively, and Cytoscape software was used to construct PPI network and screen function modules and hub genes.
RESULTS
A total of 57,835 CRC patients, including 47,823 without distant metastases and 10,012 (17.31%) with metastases, were identified. Older age, unmarried status, poorly differentiated or undifferentiated grade, right colon site, larger tumor size, N2 stage, more metastatic sites, and elevated carcinoembryonic antigen (CEA) might lead to poorer prognosis (all < 0.01). The independent risk factors of OS and CSS were included to construct a prognosis prediction model for predicting OS and CSS in CRC patients with distant metastasis. C-index and calibration curve of the training group and validation group showed that the models had acceptable predictive performance and high calibration degree. Furthermore, by comparing CRC tissues with and without liver metastasis, 158 DEGs and top 10 hub genes were screened. Hub genes were mainly concentrated in liver function and coagulation function.
CONCLUSION
The big data in the public database were counted and transformed into a prognostic evaluation tool that could be applied to the clinic, which has certain clinical significance for the formulation of the treatment plan and prognostic evaluation of CRC patients with distant metastasis.

BACKGROUND
We aimed to assess whether recurrence patterns affect survival and to use a multi-state model to predict the prognosis of early stage non-small cell lung cancer in patients who underwent surgical resection.
METHODS
Patients with early stage non-small cell lung cancer who underwent surgical resection at two tertiary medical centers between 2010 and 2015 were retrospectively analyzed. A multi-state model was employed with one initial state (surgery), two intermediate states (locoregional recurrence, distant metastasis), and one absorbing state (death), comprising five transitions: surgery to locoregional recurrence, surgery to distant metastasis, surgery to death without recurrence, locoregional recurrence to death, and distant metastasis to death. Cox proportional hazards models stratified for these transitions were performed with the risk factors; transition probabilities for each patient were predicted.
RESULTS
A total of 949 patients were identified [median age: 67 years, male: 614 (64.6%)]. Recurrence occurred in 194 (20.4%) patients (locoregional recurrence: 7.3%, distant metastasis: 13.1%). Hazard ratios for distant metastasis after surgery were higher for older age (hazard ratio: 1.03, 95% confidence interval: 1.01-1.06) and adenocarcinoma (hazard ratio: 1.67, 95% confidence interval: 1.06-2.61). Lower lobe location exhibited a higher hazard ratio for death after surgery without recurrence (hazard ratio: 1.59, 95% confidence interval: 1.00-2.53). Stage IIB lung cancer showed a higher probability of transition to distant metastasis after surgery than other stages. Cumulative transition hazards rapidly increased in both recurrence patterns until approximately two years after surgery (locoregional recurrence: 0.052; distant metastasis: 0.104). Patients with distant metastasis were more likely to die within 5 years of surgery than those with locoregional recurrence (6.8% and 2.6%, respectively).
CONCLUSIONS
With the multi-state model, risk factors and post-relapse survival probabilities differed between locoregional recurrence and distant metastasis. These findings may enable clinicians to establish personalized follow-up strategies for patients undergoing curative resection for early stage non-small cell lung cancer.

Although mostly associated with good survival outcomes, some patients with HPV-positive oropharyngeal squamous cell carcinoma develop distant metastasis and face dire prognosis. The aim of this study was to analyze distant metastatic patients in regards to survival, clinical staging, therapy approach and p16/HPV status. This retrospective single-centre study assessed patients with HPV-associated oropharyngeal cancer with distant metastasis treated in a tertiary referral center from 2005 to 2019. Overall- (OS) and survival after diagnosis of distant metastasis (OMS), clinical staging and different therapy approaches were assessed. Moreover, the overall mortality was assessed, as well as the association of different therapy approaches and p16/HPV status with the survival outcome. Out of 211 patients with HPV-associated oropharyngeal cancer that were treated in the study period, 15 developed distant metastases (7.1%). Median OS and OMS of the total group were 11 months (range 0.1-32 months) and 3 months (range 0.1-21 months), respectively. The overall mortality rate was 53.3% (n = 8). Significantly better outcome was present in patients treated with primary chemoradiotherapy (median OS 17 months vs. not reached, p = .03, median OMS 8 months vs not reached, p = .05). The OMS was significantly better in patients treated with chemotherapy initially after diagnosis (mean OMS 21 months vs 4 months; P = .001). Surgical resection after initial diagnosis was associated with a significantly shorter OMS (median OMS 3 vs. 21 months, p = .005). Interestingly, postoperative adjuvant therapy was delayed in all of these cases due to surgical site complications. Systemic treatment after initial diagnosis may be beneficial in clinical outcome of HPV associated distant metastases. Furthermore, surgical site complications should be treated with immediate care in order to avoid delay of adjuvant therapy. Further studies are warranted for validation of our results.

Liver Cancer Aug 2023The aim of this study was to determine the stage-specific incidence trend of hepatocellular carcinoma (HCC) among US adults.
INTRODUCTION
The aim of this study was to determine the stage-specific incidence trend of hepatocellular carcinoma (HCC) among US adults.
METHODS
The age-adjusted incidence rate was extracted from Surveillance, Epidemiology, and End Results database for localized, regional, and distant HCC. Trend analyses were conducted in the overall population and stratified by demographic and sociodemographic variables. The annual percentage change (APC) in 2014-2019 was estimated to determine the stage-specific incidence trend.
RESULTS
Although the incidence of localized HCC significantly declined, the incidence for regional and distant HCC plateaued in 2014-2019 (APCs, 4.4% [95% CI, -0.2% to 9.3%] and -0.7% [95% CI, -1.8% to 0.5%], respectively) with age and race/ethnicity disparities. More pronounced increases for regional and distant HCC were observed among the elderly (APCs, 8.4% [95% CI, 4.8-12.2%] and 2.2% [95% CI, 1.7-2.7%] for regional and distant HCC, respectively), non-Hispanic white individuals (APCs, 4.0% [95% CI, 2.9-5.1%] and 1.5% [95% CI, 0.7-2.4%] for regional and distant HCC, respectively).
CONCLUSIONS
Disparities in incidence trends may reflect the inequalities in access to primary health care. More efforts are still in great demand for the vulnerable population.

BACKGROUND
Fluorodeoxyglucose positron emission tomography/computed tomography (FDG-PET/CT) has been proven to be a good method to detect distant spread of head and neck cancer (HNC). However, most prior studies are based on Asian populations and may not be directly transferable to western populations.
PURPOSE
To investigate the frequency and distribution of distant metastases and synchronous malignancies detected by PET/CT in HNC in a northern Swedish population.
MATERIAL AND METHODS
All primary whole-body FDG-PET/CT examinations performed on the suspicion of HNC (n = 524 patients) between 1 January 2013 and 31 December 2016 at Umeå University Hospital in Sweden were retrospectively reviewed . After the exclusion of 189 examinations without evidence of primary HNC, 335 examinations were analyzed.
RESULTS
Distant metastases were detected in 10 (3%) patients, all with advanced primary tumors corresponding to TNM stage 3-4, most frequently in salivary gland adenocarcinoma, where 50% of patients had distant spread. Four patients had metastases below the diaphragm, representing 20% of the salivary gland malignancies. In the remaining six patients, metastases were supraphrenic, of which all but one were identified by CT alone. Synchronous malignancies were discovered in 14 (4.2%) patients, of which five were below the diaphragm.
CONCLUSION
The overall frequency of distant spread and synchronous malignancy in primary HNC was generally low. However, the risk for distant metastases below the diaphragm was relatively higher in salivary gland adenocarcinoma, supporting whole-body FDG-PET/CT in the primary diagnostic work-up in these patients.

SUMMARY
The most common sites of distant metastases of papillary thyroid carcinoma (PTC) are lung and bone. Widespread distant metastases of PTC are rare and associated with poor overall prognosis. Metastases to sites such as liver and pancreas are extremely rare, and literature is sparse on overall survival. In this report, we present a 57-year-old man whose initial presentation of PTC was with pancreatic, liver, and lung metastases, and subsequently developed metastases to bone and brain. He underwent a total thyroidectomy, neck dissection, and tracheal resection. Pathology revealed a predominant columnar cell variant PTC with focal areas of tall cell variant, and genomic sequencing showed both PIK3CA and BRAF gene mutations. Radioactive iodine ablation with I-131 did not show any uptake in metastatic sites and he had progression of the metastases within 6 months. Therefore, therapy with lenvatinib was initiated for radioactive iodine refractory disease. Our patient has tolerated the lenvatinib well, and all his sites of metastases decreased in size. His liver and pancreatic lesions took longer to respond but showed response 6 months after initiation of lenvatinib, and he remains on full dose lenvatinib 18 months into treatment.
LEARNING POINTS
Papillary thyroid carcinoma (PTC) usually metastasizes to lung and bone but can rarely occur in many other sites. Patients with distant metastases have significantly worse long-term prognosis. Lenvatinib can be an effective treatment of radioactive iodine refractory PTC with rare sites of distant metastases. Lenvatinib can be an effective treatment of PTC with BRAF V600E and PIK3CA mutation.
