Risk of second primary cancer among patients with head and neck cancers: A pooled analysis of 13 cancer registries

Separating distant recurrences from second primaries in head and neck squamous cell carcinomas - A DAHANCA group analysis on paired tumor samples

BACKGROUND

In head and neck squamous cell carcinomas (HNSCC), there is no clinically available method to separate distant metastases (DMs) from SCC secondary primary tumors. The study aimed to assess the genetic relationship in paired tumor samples.

METHODS

Patients with pairs of solid biopsies from the primary HNSCC and suspected DMs were identified (2007-2017). Targeted next-generation sequencing of 22 genes was applied, including TP53, supplemented with human papillomavirus (HPV) genotyping.

RESULTS

Of 55 pairs obtained, 33 were successfully analyzed. Distant biopsies included lung, liver, and bone. A genetic match was found in 23/33 (70%) patients, primarily with identical TP53 mutations or HPV genotypes. In 10/33 patients (30%), the genetic relationship was absent, all with lung involvement. In patients with no lung involvement, 8/8 had a match.

CONCLUSIONS

One-third of patients with DMs in HNSCC lack a genetic relationship with the primary tumors. The risk of misclassification is most prominent for patients with lung involvement.

Pain management for post-treatment survivors of complex cancers: a qualitative study of opioids and cannabis

Aim: We aimed to understand experiences with opioids and cannabis for post-treatment cancer survivors. Patients & methods: We conducted seven focus groups among head and neck and lung cancer survivors, using standard qualitative methodology to explore themes around 1) post-treatment pain and 2) utilization, perceived benefits and perceived harms of cannabis and opioids. Results & conclusion: Survivors (N = 25) experienced addiction fears, stigma and access challenges for both products. Opioids were often perceived as critical for severe pain. Cannabis reduced pain and anxiety for many survivors, suggesting that anxiety screening, as recommended in guidelines, would improve traditional pain assessment. Opioids and cannabis present complex harms and benefits for post-treatment survivors who must balance pain management and minimizing side effects.

Correlation between second and first primary cancer: systematic review and meta-analysis of 9 million cancer patients

BACKGROUND

Many survivors of a first primary cancer (FPCs) are at risk of developing a second primary cancer (SPC), with effects on patient prognosis. Primary cancers have different frequencies of specific SPC development and the development of SPCs may be closely related to the FPC. The aim of this study was to explore possible correlations between SPCs and FPCs.

METHODS

Relevant literature on SPCs was retrospectively searched and screened from four databases, namely, PubMed, EMBASE, Web of Science, and PMC. Data on the number of patients with SPC in 28 different organ sites were also collected from The Surveillance, Epidemiology, and End Results (SEER) 8 Registry and NHANES database.

RESULTS

A total of 9 617 643 patients with an FPC and 677 430 patients with an SPC were included in the meta-analysis. Patients with a first primary gynaecological cancer and thyroid cancer frequently developed a second primary breast cancer and colorectal cancer. Moreover, those with a first primary head and neck cancer, anal cancer and oesophageal cancer developed a second primary lung cancer more frequently. A second primary lung cancer and prostate cancer was also common among patients with first primary bladder cancer and penile cancer. Patients with second primary bladder cancer accounted for 56% of first primary ureteral cancer patients with SPCs.

CONCLUSIONS

This study recommends close clinical follow-up, monitoring and appropriate interventions in patients with relevant FPCs for better screening and early diagnosis of SPCs.

Value of routine follow-up for recurrence detection after treatment with curative intent for laryngeal squamous cell carcinoma

INTRODUCTION

The benefits of routine follow-up after treatment of primary laryngeal squamous cell carcinoma (LSCC) remain disputed. Guidelines worldwide are consensus-based, and evidence for specific subgroups is lacking. This study evaluates routine LSCC follow-up including flexible endoscopy for detecting locoregional recurrence (LRR).

METHODS

A retrospective cohort of 413 LSCC patients treated between 2006 and 2012 was analysed. The cumulative risk of LRR was calculated. Routine follow-up was evaluated by follow-up visit (routine or interval) at which LRR was detected, LRR treatment intent, and overall survival (OS). Analyses were stratified by early (I-II) and advanced (III-IV) TNM-stage.

RESULTS

There were 263 (64 %) patients with early-stage and 132 (32 %) patients with advanced-stage LSCC. One-, two- and five-year cumulative risks for LRR after early-stage LSCC were 8 %, 18 %, and 26 %. For advanced-stage LSCC, cumulative risks of LRR were 20 %, 30 %, and 35 %. Of all 69 LRRs after early-stage LSCC, 72 % were routine-detected, 81 % were symptomatic, and 90 % received curative-intent treatment. Of all 45 LRRs following advanced-stage LSCC, 42 % were routine-detected, 84 % were symptomatic, and 62 % received curative-intent treatment. Five-year OS of early-stage LSCC with routine-detected LRR was 70 %, and 72 % for interval-detection (log-rank-p = 0.91). Five-year OS of advanced-stage LSCC with routine-detected LRR was 37 %, and 18 % for interval-detection (log-rank-p = 0.06).

CONCLUSIONS

Routine follow-up for detecting asymptomatic recurrences seems redundant for early-stage LSCC. After advanced-stage LSCC, no asymptomatic recurrences were detected beyond one year posttreatment despite regular follow-up. Emphasis should be on other follow-up aspects, such as psychosocial support, especially after one year posttreatment.

Clinical Value of Endoscopic Esophageal Screening in Head and Neck Squamous Cell Carcinoma Patients

OBJECTIVE

To investigate the clinical benefit of routine esophageal screening in newly diagnosed head and neck squamous cell carcinoma (HNSCC) patients.

STUDY DESIGN

Retrospective cohort study.

SETTING

Tertiary medical center.

METHODS

This retrospective study selected newly diagnosed HNSCC patients from the Chang Gung Research Database between January 2007 and December 2019. Patients who underwent endoscopic esophageal examinations within 2 months of the initial diagnosis of HNSCC were included in the screening group. The clinical outcomes of the screening and nonscreening groups were analyzed.

RESULTS

In total, 13,627 HNSCC patients were included, comprising 1032 females and 12,640 males (mean age 55.0 years), and the esophageal screening group included 7033 (51.4%) patients. The prevalence rate of esophageal tumors was 4.5%. Hypopharyngeal cancer patients were the most likely to have (13.4%) second primary esophageal tumors. The American Joint Committee on Cancer stage of the esophageal tumor was lower in the esophageal screening group than in the nonesophageal screening group. The oral, oropharyngeal, and hypopharyngeal cancer patients in the esophageal screening group had better survival outcomes than their counterparts in the nonesophageal screening group.

CONCLUSION

Endoscopic esophageal screening of newly diagnosed HNSCC patients can detect esophageal tumors at an early stage and improve overall survival. Esophageal screening could be a routine survey in HNSCC patients, particularly those with lifestyle risk factors and in countries with a high prevalence of esophageal cancer.

Large-data contextualizations of social determinant associations in pediatric head and neck cancers

PURPOSE OF REVIEW

Prior investigations in social determinants of health (SDoH) and their impact on pediatric head and neck cancers are limited by the narrow scope of cancer types and SDoH being studied while lacking inquiry on the interrelational contribution of varied SDoH in real-world contexts. The purpose of this review is to discuss the current research tackling these shortcomings of SDoH-based studies in head and neck cancer and to discuss means of applying these findings in prospective initiatives and implementations.

RECENT FINDINGS

Through leveraging contemporary, large-data analyses measuring diverse social vulnerabilities, several studies have identified comprehensive delineations of which social disparities contribute the largest quantifiable impact on the care of head and neck cancer patients. Progressing from prior SDoH-based research of the decade, these studies contextualize the effect of social vulnerabilities and have laid the foundations to begin addressing these issues in the complex, modern-day environment of interrelatedsocial factors.

SUMMARY

Social determinants of health markedly affect pediatric head and neck cancer care and prognosis in complex and surprising ways. Modern-day tools and analyses derived from large-data techniques have unveiled the quantifiable underpinnings of how SDoH impact these pathologies.

Locally Advanced Laryngeal Squamous cell Carcinoma in a Patient with a Synchronous Second Primary Thyroid Carcinoma

Laryngeal squamous cell carcinoma (SCC) is one of the most common primary tumors of the head and neck region. Unfortunately, patients with laryngeal SCC tend to develop second primary tumors (SPTs), accounting for increased mortality. The lung is the predominant site of a second presentation, followed by the mucosa of the upper aerodigestive tract. In contrast, the thyroid gland rarely hosts an SPT. Our study describes the management and treatment of a 69-year-old female who presented with a rare combination of synchronous laryngeal and thyroid carcinomas.

Second esophageal neoplasms after head and neck index tumor: Incidence, risk factors and prognosis

OBJECTIVE

Patients with head and neck squamous cell carcinoma (HNSCC) have an increased risk of second esophageal neoplasms. The aim of the present study is to evaluate the incidence, risk factors and prognosis of second esophageal neoplasms in patients with HNSCC.

METHODS

A retrospective study of 4711 patients with index tumor in the oral cavity, oropharynx, hypopharynx or larynx between 1985 and 2020 was conducted.

RESULTS

During the period analysed 149 patients (3.2%) had a second esophageal neoplasm. The incidence of second esophageal neoplasia was 0.42% per year and remained nearly constant throughout the follow-up period. According to the results of a multivariate study, the risk factors related to the appearance of second esophageal neoplasms were a history of high alcohol consumption and the location of the primary tumor in the oropharynx or hypopharynx. The 5-year disease-specific survival rate in patients with a second esophageal neoplasm, calculated from the diagnosis of this second neoplasm, was 10.5%.

CONCLUSIONS

Patients with a HNSCC have an increased risk of developing of a second esophageal neoplasm. The risk factors associated with the appearance of a second esophageal neoplasm were severe alcohol consumption and the location of the primary tumor in the oropharynx or hypopharynx.

Functional and quality-of-life outcomes following salvage surgery for recurrent squamous cell carcinoma of the head and neck: a systematic review and meta-analysis

BACKGROUND

Recurrent head and neck squamous cell carcinomas (HNSCC) are frequently managed with salvage surgery, but the impact these operations have on function and quality-of-life (QoL) is understudied. This review aimed to provide a quantitative and qualitative assessment of the functional and QoL effects of salvage surgical procedures.

METHODS

Systematic review and meta-analysis were conducted of studies reporting QoL and function following salvage HNSCC resections.

RESULTS

The search identified 415 articles and 34 were selected for inclusion. Pooled random effects analysis revealed long-term feeding and tracheostomy tube rates of 18% and 7%. Pooled long-term feeding tube rates in open oral and oropharyngeal, transoral robotic, total and partial laryngectomy surgeries were 41%, 25%, 11% and 4%. Eight studies used validated QoL questionnaires.

CONCLUSIONS

Functional and QoL outcomes from salvage surgery are acceptable, but appear to be worse following open procedures. Prospective studies measuring changes over time are needed to assess these procedures impact on patient well-being.

Significant risk of second primary cancer among laryngeal squamous cell carcinoma patients even after 20 years

BACKGROUND

Evidence on the risk of second primary cancer (SPC) following primary laryngeal squamous cell carcinoma (LSCC) is limited, especially in Europe.

METHODS

Patients diagnosed with primary LSCC from 1953-2018 were retrieved from the Finnish Cancer Registry. A total of 6241 LSCC patients were identified adding to 49,393 person-years (PY) of follow-up until the end of 2019. Only one patient emigrated and was lost to follow-up. Both standardized incidence ratios (SIR) and excess absolute risk (EAR) per 1000 person-years at risk (PYR) of second primary cancer (SPC) were calculated relative to the general population. Only non-laryngeal SPCs diagnosed six months after diagnosis of primary LSCC were included.

RESULTS

A SPC was diagnosed in 1244 LSCC patients (20% of all LSCC patients) over the 65-year period, predominantly in men (92%, n = 1170). Out of all SPCs, 34% were diagnosed within 0.5 to 5 years and 66% after 5 years from primary LSCC. Among male patients, the overall SIR for SPC at any location was 1.61 (95% CI: 1.52-1.71), corresponding to 9.49 excess SPCs per 1000 PYR (95% CI: 8.19-11). The corresponding SIR for women was 1.47 (95% CI: 1.15-1.84), yielding 4.82 excess SPCs per 1000 PYR (95% CI: 2.36-9.84). The risk remained significant even after 20 years of follow-up (SIR for all 1.73, 95% CI: 1.49-2.01 and EAR 16.8 per 1000 PY, 11.88-23.75). The risk for SPC was also significantly elevated in all age groups, except <40. The highest SIRs were for SPCs arising in the mouth/pharynx (SIR for all 3.08, 95% CI: 2.36-3.95 and EAR 0.80 per 1000 PY, 0.55-1.15) and lungs (3.02, 2.75-3.30 and 5.90 per 1000, 5.13-6.78).

CONCLUSION

Patients with LSCC as primary cancer have a 60% excess risk for an SPC, especially for tobacco-associated cancers, remaining significantly elevated even decades after treatment.

Complications following salvage transoral robotic surgery with and without reconstruction: A systematic review of the literature

BACKGROUND

Transoral robotic surgery (TORS) has been used in the salvage setting for head and neck cancers both with and without reconstruction. The complications of salvage TORS and the effect of reconstruction on complications has not been studied.

OBJECTIVE

To study the complications of salvage TORS and examine the effect of reconstruction on complication rates.

METHOD

An electronic search of the English- language literature using PubMed, Medline, and the Cochrane database was conducted and a systematic review performed in accordance with PRISMA guidelines (CRD42020181057).

RESULTS

A total of 23 studies including 533 patients have been published on salvage TORS.The average patient age was 61.2 years.Prior treatment was described for 420 patients.205 (48.8%) underwent prior definitive radiotherapy (RT).160 (38.1%) underwent definitive chemoradiotherapy (CRT).Only 55 (13.1%) had prior surgery.Overall, there were 158 complications with a pooled rate of 33.6% (95%CI: 25.4-42.3%).77 were major complications requiring surgical intervention with a pooled rate of 18.9% (95% CI: 14.8-23.3%).The number of patients undergoing reconstruction among salvage cases in the literature is 59 (9.19%), with 24 local flaps and 25 microvascular free flaps.Reconstruction was associated with lower overall hemorrhage rates but had no impact on major hemorrhage rates.

CONCLUSIONS

The pooled incidence rates of major complications, major POH and emergency tracheostomy following salvage TORS are 18.9%, 10.5%, and 4.4%.The rate of death following salvage TORS is 3.6%. Reconstruction was associated with lower overall hemorrhage rate after salvage TORS but had no impact on major postoperative hemorrhage rates.

Oral Complications from Oropharyngeal Cancer Therapy

Post-oropharyngeal cancer treatment complications include a multitude of oral side effects that impact overall survival and quality of life. These include acute and chronic conditions affecting the oral cavity and head and neck, such as mucositis, infection, xerostomia, dysgeusia, radiation caries, osteonecrosis, and trismus. This review will summarize the most common oral complications from oropharyngeal cancer therapy. The authors would like to point out that the literature cited frequently combines oropharyngeal and head and neck cancer results. If recommendations are made strictly related to oropharyngeal cancers, this will be highlighted.

Is long-term screening for lung cancer justified in patients with head and neck carcinoma?

OBJECTIVE

Patients with head and neck squamous cell carcinoma (HNSCC) have a higher risk of second lung neoplasms than the general population. The aim of the present study is to evaluate the long-term incidence of second lung malignancies after the diagnosis of a HNSCC and to consider the convenience of the screening for lung cancer in these patients.

MATERIAL AND METHODS

We conducted a retrospective study performed on 4954 patients with an index tumor located in the oral cavity, oropharynx, hypopharynx, or larynx during the period 1985-2017.

RESULTS

During the follow-up period 469 patients (9.5%) presented a second pulmonary neoplasm. The incidence of second lung neoplasm was 1.26% per year and remained practically constant throughout the 25-year follow-up period analyzed. According to the results of a multivariate study, male patients, aged between 50 and 80 years, with a history of tobacco use, and with tumors located in the oropharynx or the supraglottis were those with the highest risk of second lung neoplasms.

CONCLUSION

Patients with a HNSCC index tumor have a high risk of second neoplasms located in the lung. In order to achieve an early diagnosis of these second neoplasms, it would be advisable to establish screening protocols based on the use of low-dose lung CT, which should be maintained indefinitely during the follow-up period.

A nationwide study on cancer recurrences, second primary tumours, distant metastases and survival after treatment for primary head and neck cancer in the Netherlands

INTRODUCTION

There is no consensus on the optimal duration of post-treatment follow-up after head and neck cancer (HNC). To generate site-specific input for follow-up guidelines, this study describes the incidence and timing of manifestations of disease during five years of follow-up.

METHODS

All patients diagnosed with HNC in the Netherlands in 2015 were selected from the Netherlands Cancer Registry. The follow-up events local recurrence (LR), regional recurrence (RR), second primary tumour (SPT), distant metastasis (DM) and death were studied per follow-up-year. The cumulative incidence of these events was calculated using competing risk analyses, with LR, RR and SPT of the head and neck (SPHNC) as events and SPT outside the head-neck (SPOHN), DM and death as competing events. Analyses were performed for oral cavity-, oropharynx-, larynx- and hypopharynx squamous cell carcinoma (SCC), and all HNC patients.

RESULTS

The 1-, 1.5-, and 2-year cumulative incidence of an event (LR, RR, SPHNC) were 10% (95%CI 8-13), 12% (95%CI 10-15), and 13% (95%CI 10-16) for oral cavity SCC; 6% (95%CI 4-9), 10% (95%CI 7-14), and 11% (95%CI 8-15) for oropharynx SCC; 7% (95%CI 5-10), 11% (95%CI 9-15), and 13% (95%CI 10-16) for larynx SCC and 11% (95%CI 6-19), 19% (95%CI 12-27), and 19% (95%CI 12-27) for hypopharynx SCC.

CONCLUSIONS

One year of follow-up for oral cavity SCC, and 1.5 years for oropharynx-, larynx-, and hypopharynx SCC suffices for the goal of detecting disease manifestations after treatment. More research into other aspects of follow-up care should be performed to determine the optimal follow-up regimen.

NSD Overexpression in the Fat Body Increases Antimicrobial Peptide Production by the Immune Deficiency Pathway in Drosophila

Nuclear receptor-binding SET domain-containing protein 1 (NSD1) inactivation in tumor cells contributes to an immune-cold phenotype, indicating its potential association with immune disturbances. Drosophila NSD is a homolog of the human NSD1. Thus, in this study, we investigated the effect of NSD overexpression in the fat body, the central organ involved in Drosophila immune responses. Upon ectopic expression of NSD in the fat body, the mRNA levels of antimicrobial peptides increased. Using reporter constructs containing deletions of various NF-κB sites in the Attacin-A (AttA) promoter, we found that transcriptional activation by NSD is mainly mediated via the IMD pathway by activating Relish. Since the IMD pathway is required to resist Gram-negative bacterial infections, we further examined the effect of fat body-specific NSD overexpression on Drosophila immune defenses. Upon oral ingestion of Gram-negative Pseudomonas entomophila, the survival rate of the NSD-overexpressing larvae was higher than that of the wild type, suggesting a positive role of NSD in immune responses. Taken together, these results suggest the association of NSD with the IMD pathway and is thus expected to contribute to the elucidation of the molecular mechanisms of immune malfunction in various NSD1-associated human diseases.

Combination therapy with oncolytic viruses and immune checkpoint inhibitors in head and neck squamous cell carcinomas: an approach of complementary advantages

Squamous cell carcinomas are the most common head and neck malignancies. Significant progress has been made in standard therapeutic methods combining surgery, radiation, and chemotherapy. Nevertheless, the 5-year survival rate remains at 40-50%. Immune checkpoint inhibitors (ICIs) are a new strategy for treating head and neck squamous cell carcinomas (HNSCCs). Still, the overall response and effective rates are poor, as HNSCCs are 'cold' tumors with an immunosuppressive tumor microenvironment (TME), limiting ICI's beneficial effects. In this case, transforming the tumor suppression microenvironment before using ICIs could be helpful. Oncolytic viruses (OVs) can transform cold tumors into hot tumors, improving the situation. Talimogene laherparepvec (T-VEC), oncolytic immunotherapy authorized for advanced melanoma, also showed good safety and antitumor activity in treating head and neck cancer and pancreatic cancer. In combination with pembrolizumab, T-Vec may have more anticancer efficacy than either drug alone. Therefore, understanding the mechanisms underpinning OVs and their potential synergism with ICIs could benefit patients with HNSCC.

Multiple primary head and neck squamous cell cancer: Lessons learnt

AIM

To analyze the demographic profile, treatment outcome, and factors affecting them in multiple primary head and neck squamous cell cancer (MPHNSCC) patients.

MATERIALS AND METHODS

Hospital case records of patients with histopathology proven MPHNSCC registered in the radiation oncology department from January 2008 to December 2020 were retrospectively studied. Modified Warren-Gates criteria were used to define MPHNSCC. Demographic and clinical details were recorded and analyzed.

RESULTS

Twenty-seven patients had histopathology proven MPHNSCC. The median age at diagnosis of an index case was 50 years (minimum 26, maximum 70) with a male to female sex ratio of 22:5. Seventeen (62.96%) patients were tobacco users; either smoked or smokeless. The oral cavity was the commonest sub-site for both an index and second primary malignancy (22 patients; 81.48%) and the majority presented in a locally advanced stage of disease (10; 37.03% and 16; 62.95% for an index and second primary, respectively). The presentation was simultaneous, synchronous, and metachronous in 1 (3.7%), 2 (7.4%), and 24 (88.89%) patients, respectively. Two patients had three sites of MPHNSCC. The average duration of chronicity was 54.37 months (min. 8 and max. 156). MPHNSCC were ipsilateral in 10 (37.04%) patients and re-irradiation was planned for 22 (81.48%) patients with 50% treatment compliance. At the time of the last hospital visit, 18 (66.66%) patients were alive with disease, 7 (25.92%) patients were alive without disease, and 2 (7.40%) patients died of disease.

CONCLUSION

A higher percentage of MPHNSCC originated from the oral cavity and the majority presented in the locally advanced stage of disease; despite the site being accessible to self-oral examination. Patient education and physician's awareness regarding the MPHNSCC are needed.

Impact of primary site on survival in patients with nasopharyngeal carcinoma from 2004 to 2015

Background

Nasopharynx carcinoma (NPC) is the most common malignant tumor of the nasopharynx. Many studies have shown some factors related with the prognosis of NPC patients. Our study aims to evaluate the differences of prognosis between initial and second primary NPC.

Material and methods

The Surveillance, Epidemiology, and End Results (SEER) program was used to perform the population-based analysis in NPC patients who were newly diagnosed between 2004 and 2015. Kaplan-Meier and Cox regressions were used to evaluate the effects of primary site on the overall survival (OS), as well as the cancer-specific survival (CSS).

Results

Our study included 5,012 NPC patients: 4,474 initial primary NPC patients and 5,38 s primary NPC patients. Significant differences were observed in sex, age at diagnosis, race, median household income, histological type, American Joint Committee on Cancer (AJCC) stage, N-stage, radiation treatment and chemotherapy between patients with initial and second NPC (P < 0.05). Moreover, the patients with second NPC had longer survival months. In addition, radiation and chemotherapy were recommended both in first and second primary NPC patients.

Conclusion

Worse prognosis was observed in patients with second primary NPC compared with those with primary NPC in all subgroups of AJCC stage and age at diagnosis.

Factors associated with the development of second primary tumours in head and neck cancer patients

INTRODUCTION

The development of second primary tumours (SPTs) is one of the main causes of low survival in patients with head and neck cancer (HNC). The aim of this study was to review the evidence about factors associated with developing SPTs in patients with HNC.

METHODS

An updated systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines, and the search was performed in Pubmed and Scopus. Only original articles with a cohort or case-control design were included. Article quality was assessed with the Newcastle-Ottawa scale.

RESULTS

Thirty-six and two case-control studies were included, with quality medium (n = 5) to high (n = 33). Tobacco showed a significant association with SPT development, with risks ranging from 1.41 (95%CI: 1.04-1.91) to 5.52 (95%CI: 2.91-10.49). Regarding alcohol, risks ranged from 1.46 (95%CI: 1.12-1.91) to 21.3 (95%CI: 2.9-156). Location of the index tumour in the hypopharynx/oropharynx, absence of human papillomavirus and presence of a premalignant lesion also increased the risk of SPTs. More controversy was found for sex, age and other clinical factors of the tumour.

CONCLUSION

Toxic lifestyle habits and clinical factors were associated with the risk of SPTs in HNC patients. These findings may improve individualised prevention strategies in its follow-up.

A novel diagnostic model for differentiation of lung metastasis from primary lung cancer in patients with colorectal cancer

Objective

This study aimed to evaluate the ¹⁸F-FDG PET/CT in differentiating lung metastasis(LM) from primary lung cancer(LC) in patients with colorectal cancer (CRC).

Methods

A total of 120 CRC patients (80 male, 40 female) who underwent ¹⁸F-FDG PET/CT were included. The diagnosis of primary lung cancer or lung metastasis was based on histopathology The patients were divided into a training cohort and a validation cohort randomized 1:1. Independent risk factors were extracted through the clinical information and ¹⁸F-FDG PET/CT imaging characteristics of patients in the validation cohort, and then a diagnostic model was constructed and a nomograms was made. ROC curve, calibration curve, cutoff, sensitivity, specificity, and accuracy were used to evaluate the prediction performance of the diagnostic model.

Results

One hundred and twenty Indeterminate lung lesions (ILLs) (77 lung metastasis, 43 primary lung cancer) were analyzed. No significant difference in clinical characteristics and imaging features between the training and the validation cohorts (P > 0. 05). Using uni-/multivariate analysis, pleural tags and contour were identified as independent predictors. These independent predictors were used to establish a diagnostic model with areas under the receiver operating characteristic curves (AUCs) of 0.92 and 0.89 in the primary and validation cohorts, respectively. The accuracy rate of the diagnostic model for differentiating LM from LC were higher than that of subjective diagnosis (P < 0.05).

Conclusions

Pleural tags and contour were identified as independent predictors. The diagnostic model of ILLs in patients with CRC could help differentiate between LM and LC.

Association between postoperative radiotherapy for young-onset head and neck cancer and long-term risk of second primary malignancy: a population-based study

Background

Second primary malignancy (SPM) represents the leading long-term cause of death among patients with index head and neck squamous cell carcinoma (HNSCC). We aimed to quantify the association between postoperative radiotherapy (PORT) and the risk of SPM development for index HNSCC among adolescent and young patients, who are particularly vulnerable to radiation-associated impacts due to their increased tissue susceptibilities and longer life expectancies.

Methods

This study was conducted using the Surveillance, Epidemiology, and End Results (SEER) database to collect the data of 5 year survivors of index young-onset HNSCC from 1975 to 2011. The outcome of interest was SPM, a new, metachronous malignancy after the index HNSCC. Standardized incidence ratios (SIRs) and excess absolute risks (EARs) were used to quantify the PORT-associated risks externally, and relative risks (RRs) were estimated by the multivariate Poisson regression analysis to quantify the PORT-associated risks internally.

Results

Of the included 2771 5 year survivors with index young-onset HNSCCs, the receipt of PORT (37.6%) was associated with higher risk of SPMs (RR, 1.23; 95% CI 1.07 to 1.43). PORT-associated risks were elevated for the majority of sites, including head and neck (RR, 1.19; 95% CI 0.95 to 1.50) and lung (RR, 1.67; 95% CI 1.18 to 2.34). With regarding to the subsites of head and neck, RRs were above unity in oral cavity squamous cell carcinoma (SCC) (RR, 1.68; 95% CI 1.39 to 2.03) and laryngeal SCC (RR, 1.02; 95% CI 0.73 to 1.43). A relatively greater RR was observed for patients younger than 35 years (RR, 1.44, 95% CI 0.37 to 5.57) and those diagnosed with localized diseases (RR, 1.16, 95% CI 0.9 to 1.5). PORT-associated risks were increased remarkably after 15 years of follow-up (RR, 1.24; 95% CI 0.97 to 1.58).

Conclusions

An association was discovered between PORT treatment and increased long-term risk of SPM among patients with index young-onset HNSCC. The findings suggest long-term follow-up surveillance for these patients, particularly those with oral cavity SCC or laryngeal SCC.

The Role of HPV in Determining Treatment, Survival, and Prognosis of Head and Neck Squamous Cell Carcinoma

Human papillomavirus (HPV) infection has been identified as a significant etiological agent in the development of head and neck squamous cell carcinoma (HNSCC). HPV's involvement has alluded to better survival and prognosis in patients and suggests that different treatment strategies may be appropriate for them. Only some data on the epidemiology of HPV infection in the oropharyngeal, oral cavity, and laryngeal SCC exists in Europe. Thus, this study was carried out to investigate HPV's impact on HNSCC patient outcomes in the Irish population, one of the largest studies of its kind using consistent HPV testing techniques. A total of 861 primary oropharyngeal, oral cavity, and laryngeal SCC (OPSCC, OSCC, LSCC) cases diagnosed between 1994 and 2013, identified through the National Cancer Registry of Ireland (NCRI), were obtained from hospitals across Ireland and tested for HPV DNA using Multiplex PCR Luminex technology based in and sanctioned by the International Agency for Research on Cancer (IARC). Both overall and cancer-specific survival were significantly improved amongst all HPV-positive patients together, though HPV status was only a significant predictor of survival in the oropharynx. Amongst HPV-positive patients in the oropharynx, surgery alone was associated with prolonged survival, alluding to the potential for de-escalation of treatment in HPV-related OPSCC in particular. Cumulatively, these findings highlight the need for continued investigation into treatment pathways for HPV-related OPSCC, the relevance of introducing boys into national HPV vaccination programs, and the relevance of the nona-valent Gardasil-9 vaccine to HNSCC prevention.

SDF-1α predicts poor prognosis in patients with locally advanced esophageal squamous cell carcinoma receiving definitive concurrent chemoradiotherapy

BACKGROUND

Stromal cell-derived factor-1α (SDF-1α) is a chemokine associated with tumor progression in various types of cancers. The current study aimed to evaluate whether pre-treatment or kinetics of SDF-1α can predict the prognosis in patients with esophageal squamous cell carcinoma (ESCC) receiving definitive concurrent chemoradiotherapy (CCRT).

METHODS

A total of 97 patients with ESCC were identified at Kaohsiung Chang Gung Memorial Hospital between January 2010 and December 2015. Serum concentration of SDF-1α was measured at day 0 (pre-treatment) and chemotherapy day 28 to determine its kinetics and the cut-off level of pre-chemotherapy SDF-1α was 1.5 ng/mL. Two ESCC cell lines, TE1 and KYSE30, were selected to evaluate the function of SDF-1α.

RESULTS

Univariate and multivariate analyses showed that pre-treatment SDF-1α ≥ 1.5 ng/mL and an increased SDF-1α level after treatment were significantly associated with worse progression-free survival (p = 0.021 and p = 0.008, respectively) and overall survival (p = 0.005 and p < 0.001, respectively). In addition, patients with pre-treatment SDF-1α ≥ 1.5 ng/mL and increased SDF-1α levels after treatment were found to have poor response to CCRT. Moreover, these cell lines were treated with chemotherapeutic agents (cisplatin or 5-FU) and SDF-1α, alone or in combination. Our in vitro study results showed SDF-1α promoted the proliferation of tumor cells and overcame the cytotoxic effect of chemotherapy (p < 0.001).

CONCLUSION

Our study suggested that SDF-1α plays an important role in ESCC disease progression and that pre-treatment SDF-1α level and kinetics of SDF-1α are the independent prognostic factors for ESCC patients receiving definitive CCRT. Periodic determinations of serum SDF-1α level may be valuable to predict prognosis of ESCC in clinical practice.

Second primary cancer following primary oral squamous cell carcinoma: a population-based, retrospective study

BACKGROUND

Second primary cancer (SPC), defined as a metachronous solid cancer resulting from neither a recurrence of the primary cancer nor a metastasis, is a leading long-term cause of death for survivors of primary oral squamous cell carcinoma (OSCC). This study examined the risk of SPC following treatment of primary OSCC.

MATERIALS AND METHODS

This semi-national, population-based, retrospective study included all patients with primary OSCC treated with curative intent in Eastern Denmark in 2000-2014. The presence of SPC was confirmed from medical records and the Danish Pathology Data Bank. The rate of SPC was compared to the occurrence of any cancer in the Eastern Danish population using data from the Danish Cancer Registry.

RESULTS

A total of 936 patients with primary OSSC were enrolled. Of these, 219 patients (23%) were diagnosed with SPC during the follow-up (median 8.9 years, IQR: 5.4-12.6 years). The rate of SPC was four times higher than the occurrence of any cancer among the Eastern Danish population i.e., with a standardized incidence ratio (SIR) of 4.13 (95%CI: 3.55-4.80). SPCs were most frequently found in head and neck region (n = 97, SIR = 43.6), lower respiratory organs (n = 38, SIR = 5.6) and gastrointestinal organs (n = 33, SIR = 3.2) with increased SPC rates in all locations. Among patients who developed SPC within the study period the median time from OSCC to the first SPC was 4.4 years (IQR: 2.5-6.2). Significant associations were found between both smoking and excessive alcohol consumption after treatment of OSCC and the risk of SPC.

CONCLUSIONS

A noteworthy increased rate of SPC following treatment of primary OSCC was found, especially in the head and neck region and in the lungs. Healthcare professionals should be aware of this increased risk.

The Emerging Role of Long Non-Coding RNAs in Esophageal Cancer: Functions in Tumorigenesis and Clinical Implications

Esophageal cancer (EC) is one of the most common malignancies of digestive tracts with poor five-year survival rate. Hence, it is very significant to further investigate the occurrence and development mechanism of esophageal cancer, find more effective biomarkers and promote early diagnosis and effective treatment. Long non-coding RNAs (lncRNAs) are generally defined as non-protein-coding RNAs with more than 200 nucleotides in length. Existing researches have shown that lncRNAs could act as sponges, guides, scaffolds, and signal molecules to influence the oncogene or tumor suppressor expressions at transcriptional, post-transcriptional, and protein levels in crucial cellular processes. Currently, the dysregulated lncRNAs are reported to involve in the pathogenesis and progression of EC. Importantly, targeting EC-related lncRNAs through genome editing, RNA interference and molecule drugs may be one of the most potential therapeutic methods for the future EC treatment. In this review, we summarized the biological functions and molecular mechanisms of lncRNAs, including oncogenic lncRNAs and tumor suppressor lncRNAs in EC. In addition, we generalized the excellent potential lncRNA candidates for diagnosis, prognosis and therapy in EC. Finally, we discussed the current challenges and opportunities of lncRNAs for EC.

Second primary squamous cell carcinomas treated with trans oral robotic surgery: Oncological and functional results

Background

Recovery of swallowing in patients treated with trans‐oral robotic surgery (TORS) is in general considered as favorable. However, patients afflicted with a secondary primary carcinoma of the head and neck may be more vulnerable to swallowing dysfunctions after trans‐oral surgery as a consequence of previous treatments.

Methods

This is a retrospective monocentric study on patients undergoing TORS for second primary squamous cell carcinoma between 2013 and 2017 (follow‐up until June 2021). Swallowing performance was assessed via the functional outcome swallowing scale (FOSS). Also, overall survival (OS), disease‐free survival (DS) and disease‐specific survival (DSS) were evaluated.

Results

Eighteen patients (median 62 years) underwent TORS with curative intent for T1‐2 oropharyngeal and supraglottic secondary primaries. The average follow‐up was of 52 months. All cases were resected R0 using TORS. 84% of patients had a post‐treatment FOSS score equal or better upon last follow‐up compared with pre‐treatment. Only one patient required a percutaneous gastrostomy long term. DSS/DFS/OS at 5 years was 94%, 60%, and 67%, respectively. The main cause of death was metachronous pulmonary neoplasia.

Conclusions

Our study demonstrates encouraging results in terms of swallowing recovery in patients undergoing TORS for selected secondary primaries of the oropharynx and supraglottic larynx. Further studies into trans‐oral surgery for this condition seem therefore warranted.

A Novel Overall Survival Nomogram Prediction of Secondary Primary Malignancies after Hypopharyngeal Cancer: A Population-Based Study

Objectives

We aimed to construct a nomogram for predicting the overall survival (OS) of patients with secondary primary malignancies (SPMs) after hypopharyngeal cancer (HPC).

Methods

613 HPC patients were included in the Surveillance, Epidemiology, and End Results (SEER) database between 2000 and 2018, which were divided into training and validation cohorts. The least absolute shrinkage and selection operation (LASSO) and stepwise Cox regression were used to determine the variables by which a nomogram model was established.

Results

After the LASSO and stepwise Cox regression analysis, the age, year of diagnosis, sites of SPMs, SEER stage of SPMs, surgery for SPMs, and radiotherapy for SPMs were included for model establishment. The ROC curve showed good discrimination for the 3- and 5-year AUC values in the training (0.774 and 0.779, respectively) and validation (0.758 and 0.763, respectively) cohorts. The calibration curve indicated good prognostic accuracy, especially in the 5-year survival prediction for this model. The DCA also demonstrated clinical efficacy over a wide range of threshold probabilities. Lastly, the risk group classified by the individual nomogram values showed significantly different survival outcomes in both training and validation cohorts.

Conclusions

We constructed a nomogram to predict the OS of SPMs after HPC with good clinical values.

Mutation Analysis of Second Primary Tumors in Oral Cancer in Taiwanese Patients through Next-Generation Sequencing

Head and neck cancer has poor overall survival. Patients with head and neck cancer more frequently develop second primary tumors than do patients with other cancers, leading to a poor prognosis. In this study, we used next-generation sequencing to analyze and compare mutations between first tumors and second tumors in oral cancer. We retrieved tumor tissues collected from 13 patients who were diagnosed twice as having cancer. We used driver gene and trunk mutations to distinguish between recurrent cancer and primary cancer in oral cancer. We observed unique driver gene mutations in three patients with an initial clinical diagnosis of recurrent cancer; hence, we believe that the corresponding patients had primary cancer. Four patients with an initial clinical diagnosis of primary cancer were found to actually have recurrent cancer according to our results. Genetic testing can be used to enhance the accuracy of clinical diagnosis.

Mutagen sensitivity and risk of second cancer in younger adults with head and neck squamous cell cancer: 15-year results

Purpose

To evaluate the mutagen sensitivity phenotype on the risk of second primary cancer (SPC) in patients with head and neck squamous cell carcinoma (HNSCC), and to estimate the long-term rate of SPC and the outcome with SPC.

Methods

A survey was made regarding SPC among 124 younger (≤ 50 years) adults with HNSCC who were enrolled in a pretreatment mutagen sensitivity investigation during 1996–2006. Mutagen sensitivity was assessed by exposing lymphocytes to bleomycin in vitro and quantifying the bleomycin-induced chromatid breaks per cell (b/c). Patients were classified as hypersensitive (> 1 b/c) or not hypersensitive (≤ 1 b/c).

Results

Mean follow-up time for all patients was 68 months (range: 5–288 months), and the 15-year cancer-specific survival was 15%. Twenty patients (16%) developed a SPC (15-year estimated rate: 41%), and half of them was hypersensitive. The crude rate of SPC for hypersensitive (n = 65) or not hypersensitive (n = 59) patients were 15 and 17%, respectively (p = 0.4272). The 15-year estimated rate of SPC for hypersensitive and not hypersensitive patients was 36 and 48%, respectively (p = 0.3743). Gender, UICC stages, anatomical sites of index cancer did not prove to be a significant risk factor for SPC. Forty-five percent of SPC developed after the 10-year follow-up. The 3‑year cancer-specific survival was 23% with SPC.

Conclusion

According to our findings, mutagen hypersensitivity was not associated with an increased SPC risk in HNSCC patients. Patients are at a lifelong risk of developing a SPC. Survival with SPC is very poor.

Clinical characteristics and prognosis of patients with hypopharyngeal cancers with multiple primary cancers: A propensity score matched analysis

PURPOSE

This study aimed to identify the clinical characteristics of hypopharyngeal squamous cell carcinoma (HPSCC) patients with multiple primary cancers (MPCs) and to compare differences between patients with metachronous and synchronous MPCs.

MATERIAL AND METHODS

This study included 219 patients with HPSCC treated at our center between 2008 and 2020; the clinical characteristics and prognosis of 66 patients with MPCs were analyzed. Propensity score matching (PSM) was used to balance the factors between patients with synchronous and metachronous MPCs.

RESULTS

Sixty-six patients with HPSCC (66/219, 30.1%) experienced MPCs, of which 29 were synchronous and 37 were metachronous. The esophagus (n = 39, 59.1%), lung (n = 10, 15.2%), and oropharynx (n = 4, 6.1%) were the three most common sites of MPCs in both the synchronous and metachronous groups. More patients with synchronous MPCs were stage T1-2 (82.8% vs. 59.5%, P = 0.041) compared to those with metachronous MPCs. Among the 24 pairs of patients after PSM, patients with metachronous MPCs had higher 3-year progression-free survival (PFS) (52.5% vs. 16.3%, P < 0.001) and overall survival (OS) (58.5% vs. 22.1%, P = 0.001) than those with synchronous cancers. Multivariate Cox analysis showed that patients with synchronous MPCs had shorter PFS (HR 4.45, 95% CI 1.819-10.885, P = 0.001) and OS (HR 3.918, 95% CI 1.591-9.645, P = 0.003).

CONCLUSION

MPCs are common among patients with HPSCC, and patients with metachronous MPCs had better survival than those with synchronous MPCs. Clinicians should be aware of the possibility of MPCs in patients with HPSCC and optimize treatment to improve outcomes.

Development of second primary malignancies after transoral surgery in human papilloma virus-positive oropharyngeal squamous cell carcinoma

BACKGROUND

Little data exists regarding the incidence of oropharyngeal and upper aerodigestive tract (UADT) second primary malignancies (SPM) among human papilloma virus (HPV)-positive oropharyngeal squamous cell carcinoma (OPSCC). Here we evaluate SPM rates among patients with HPV-related OPSCC.

METHODS

A retrospective cohort study of 412 patients with HPV-related OPSCC who underwent transoral resection +/- adjuvant therapy at a single center between 1996 and 2018.

RESULTS

Twenty patients (4.9%) developed SPM of the UADT, nine (2.2%) occurring in the oropharynx. Median time to diagnosis was 59.5 months (0-173 months). Risk of SPM was lower for patients receiving adjuvant radiation (aHR: 0.25, 95%CI: 0.08-0.78). There was no difference in overall or disease-free survival between those with and without SPM.

CONCLUSION

The rate of SPM among patients with HPV-positive OPSCC is lower than reported rates among HPV-negative OPSCC. To date, this is the largest study evaluating SPM in patients with surgically treated HPV-positive OPSCC.

Secondary primary malignancy in patients with head and neck squamous cell carcinoma: 27-year experience from the perspective of diagnostic tools

Background

The survival rate of head and neck squamous cell carcinoma (HNSCC) patients with secondary primary malignancy (SPM) showed no significant improvement for decades, however, the impact of advances in diagnostic tools is rarely mentioned. This study investigated the clinical characteristic of HNSCC with SPM over a 27-year period especially from the perspective of diagnostic tools.

Methods

This study evaluated 157 HNSCC patients with SPM. The patients were divided into two groups according to the time of SPM diagnosis (Group A:1992–2003; Group B: 2004–2014). Age, gender, stage of first primary malignancy (FPM), SPM interval, overall survival, and disease-free survival were compared between groups.

Results

Group B had significantly more SPM developed rate (p = 0.002), more SPM patients with advanced stage of FPM (p = 0.001), synchronous SPM (p = 0.006), and shorter SPM interval (p<0.001) compared to Group A. The survival rate in Group B was not significantly better than Group A.

Conclusion

Among patients diagnosed with HNSCC recently, more SPMs are diagnosed in a shorter time interval and in a more advanced stage. The overall advances in diagnostic tools cannot significantly improve SPM survival, however, it enables more patients to receive corresponding treatment.

Incidence of synchronous contralateral tonsillar malignancy in a known case of unilateral tonsillar carcinoma

OBJECTIVE

The literature is divided with regards to contralateral tonsillectomy in a known/suspected case of ipsilateral tonsillar malignancy. In this study, we evaluate the incidence of indolent synchronous contralateral tonsillar malignancy (SCTC) in patients with known ipsilateral tonsillar malignancy.

METHODS

All patients diagnosed with ipsilateral tonsillar carcinoma (TC) at a tertiary teaching center between January 2016 and December 2019 were screened. None of the patients were suspected to have bilateral TC. All patients underwent appropriate imaging in the form of Magnetic resonance imaging and computed tomography of head and neck region and then underwent bilateral tonsillectomy. The prevalence of bilateral tonsillar malignancy and the factors predicting them were analyzed.

RESULTS

In all 59 patients were included in the study. The mean and median age of the patient population was 60.8 and 59 years, respectively, with a male to female ratio of 3.2:1. The incidence of bilateral tonsillar malignancy in carcinoma of unknown primary (CUP) was 3/10 (33.3%). Among the remaining 49 patients, incidence of synchronous contralateral tonsillar carcinoma (SCTC) was 2/49 (4.08%). Overall, 5/59 (8.5%) patients had synchronous bilateral tonsillar malignancy. Furthermore, dysplasia was found in the contralateral tonsil in 4/10 (40%) CUP patients. Among the remaining 49 patients, dysplasia was seen in the contralateral tonsil in 20/49 (40.8%) patients. The absence of p16 expression predicted higher probability of SCTC. Factors like gender, T stage, nodal status or smoking did not predict SCTC.

CONCLUSION

We recommend bilateral tonsillectomy in all patients with suspected or proven TC (unilateral or bilateral) and CUP as it helps identify indolent SCTC and it does not add any significant morbidity to the patients.

Prevalence and Spectrum of Second Primary Malignancies among People Living with HIV in the French Dat’AIDS Cohort

Simple Summary

People who survive primary cancers are at an increased risk for subsequent primary cancers. An increased risk for certain types of primary cancers among people living with HIV (PLWH) was demonstrated in the last few decades. Given the increasing life expectancy of PLWH, a steady increase in SPC has been reported. The main objective of this study was to describe the prevalence and spectrum of second primary cancers (SPCs) stratified by first primary cancers in HIV-positive men and women cancer survivors. We showed that the pattern of SPCs differs from that observed in the general population and according to sex. Yet, further studies are needed to determine the excess risk of SPCs in this population and to confirm the need for more appropriate screening procedures.

Abstract

Background: We aimed to describe the prevalence and spectrum of second primary cancer (SPC) in HIV-positive cancer survivors. Methods: A multicenter retrospective study was performed using longitudinal data from the French Dat’AIDS cohort. Subjects who had developed at least two primary cancers were selected. The spectrum of SPCs was stratified by the first primary cancer type and by sex. Results: Among the 44,642 patients in the Dat’AIDS cohort, 4855 were diagnosed with cancer between 1 December 1983 and 31 December 2015, of whom 444 (9.1%) developed at least two primary cancers. The most common SPCs in men were non-Hodgkin lymphoma (NHL) (22.8%), skin carcinoma (10%) and Kaposi sarcoma (KS) (8.4%), and in women the most common SPCs were breast cancer (16%), skin carcinoma (9.3%) and NHL (8%). The pattern of SPCs differed according to first primary cancer and by sex: in men, NHL was the most common SPC after primary KS and KS was the most common SPC after primary NHL; while in women, breast cancer was the most common SPC after primary NHL and primary breast cancer. Conclusion: The frequency and pattern of subsequent cancers among HIV-positive cancer survivors differed according to the first primary cancer type and sex.

Synchronous mucosal and intraosseous oral cavity carcinomas: a case of rare occult second primary malignancy

Secondary primary malignancies within the head and neck region are well documented. Within this group, synchronous tumours with an index oral cancer are usually found in the oropharyngeal or laryngeal sites. We present a rare case of an index squamous cell carcinoma in the tongue with a synchronous primary intraosseous squamous cell carcinoma. We discuss the challenges associated with investigation, diagnosis and subsequent management. Treatment aims remain the same; namely, eradicating the disease using surgery, radiotherapy, chemotherapy or a combination of these modalities. It is important to acknowledge the unpredictable pattern of tumour presentation and the need to maintain a high index of suspicion.

Image-enhanced endoscopy for detection of second primary esophageal neoplasms in patients with hypopharyngeal cancer: Prevalence, risk factors, and characteristics

BACKGROUND

Esophageal second primary neoplasms (ESPNs) are common in hypopharyngeal squamous cell carcinoma (HPSCC) patients and are associated with poor prognoses. The effectiveness of image-enhanced endoscopy (IEE) has not been well established.

METHODS

We reviewed the patients between April 2016 and April 2018 with HPSCC receiving ESPNs screening via white-light imaging, narrow-band imaging, and Lugol chromoendoscopy.

RESULTS

Of 99 eligible patients, ESPNs prevalence was 31%. Of the 69 patients assigned to the follow-up group, 23 with positive findings showed significantly increased previous histories of second primary malignancies in the upper aerodigestive tract. Among them, patients without symptoms at the time of IEE screening showed less advanced T stages and higher percentages of receiving minimal invasive therapy.

CONCLUSION

The present study represented the clinical utility of routine IEE screening in HPSCC patients and proposed routine surveillance may help identify and properly manage early-stage ESPN.

Metachronous carcinogenesis of superficial esophagus squamous cell carcinoma after endoscopic submucosal dissection: incidence and risk stratification during long-term observation

BACKGROUND

This study aimed to reveal long-term outcomes, such as incidence of metachronous esophageal and head and neck squamous cell carcinomas and overall survival rate, through long-term observation of patients with esophageal carcinoma post-endoscopic submucosal dissection.

METHODS

Risk of metachronous carcinogenesis was evaluated in 88 patients with intramucosal esophageal carcinoma (without history of metachronous esophageal or head and neck squamous cell carcinomas) who underwent endoscopic submucosal dissection from 2007 to 2008 and were endoscopically observed for > 3 years. Histologically, the papillary vessel is defined as the clock gear-like structure composed of capillaries directly penetrating the epithelium (starting from the lamina propria) and covering at least two-thirds of it, around which the tumor cells are arranged in a spiral pattern.

RESULTS

Median endoscopic follow-up period was 11.0 years. Cumulative 2-, 5-, and 10-year metachronous esophageal carcinoma rates were 11.4%, 20.6%, and 39.3%, respectively. Stepwise multivariate Cox proportional hazard regression analysis identified multiple Lugol-voiding lesions (LVLs) as the single significant independent predictor. Cumulative 2-, 5-, and 10-year metachronous head and neck squamous cell carcinoma rates were 6.9%, 10.4%, and 19.6%, respectively. Stepwise multivariate Cox proportional hazard regression analysis identified multiple LVLs, Brinkman index, papillary vessel, and younger age as significant predictive factors. Overall post-endoscopic submucosal dissection survival rates were 98.8% and 87.5% at 5 and 10 years, respectively.

CONCLUSION

Patients with a history of esophageal carcinoma remain at risk for metachronous carcinogenesis even > 5 years after endoscopic submucosal dissection. Thus, long-term follow-up is important.

Multiple Primary Malignancies in Head and Neck Cancer: A University Hospital Experience Over a Five-Year Period

Introduction

With an estimated incidence of 2%-4% per year, the development of a second primary malignancy (SPM) in patients with head and neck tumors (HNTs) is not a rare event. The present study aimed to (i) assess the frequency of SPMs in patients with HNTs treated in a university hospital over a five-year period and (ii) provide a demographic characterization of these patients.

Methods

Retrospective single-centre study of patients with more than one primary tumor (including at least one HNT) diagnosed between January 1, 2015, and December 31, 2019. Data were retrieved from patients’ clinical records and anonymized for analysis purposes.

Results

A total of 53 out of 824 (6.43%) patients with multiple primary malignancies were identified, 18 of which synchronous and 35 metachronous. The median follow-up was 25 months. Thirteen patients were diagnosed with more than one HNT. Forty patients were diagnosed with at least one HNT and one non-HNT. The most frequently diagnosed non-HNT SPMs were lung cancer (n=17) and esophageal cancer (n=8). The five-year survival rate was 53% for patients with multiple HNSCCs and 47% for patients with at least one non-HNT (log-rank p=0.729). The median overall survival was 14 months for synchronous and 58 months for metachronous SPMs (log-rank p=0.002).

Conclusion

Findings from this study highlight the importance of long-term follow-up of HNT patients for early detection of SPMs, increasing the chance of providing treatment with curative intent and improving patient outcomes and survival.

Role of NSD1 as potential therapeutic target in tumor

Nuclear receptor binding SET Domain Protein 1 (NSD1) is a bifunctional transcriptional regulatory protein that encodes histone methyltransferase. Mono- and di-methylation of H3K36 by NSD1 is mainly primarily involved in the regulation of gene expression, DNA repair, alternative splicing, and other important biological processes. Many types of cancers, including acute myelogenous leukemia (AML), liver cancer, lung cancer, endometrial carcinoma, colorectal cancer, and pancreatic cancer, are associated with NSD1 fusion, missense mutation, nonsense mutation, silent mutation, deletion, and insertion of frameshift, and deletion in a frame. Therefore, targeting NSD1 may be a potential strategy for tumor therapy. An in-depth study of the structure and biological activities of NSD1 sets the groundwork for improving tumor therapy and creating NSD1 inhibitors. This article emphasizes the role of NSD1 in tumorigenesis and the development of NSD1 targeted small-molecule inhibitors.

Patterns of alcohol use among early head and neck cancer survivors: A cross-sectional survey study using the alcohol use disorders identification test (AUDIT)

OBJECTIVE

Alcohol use among survivors of head and neck cancer (HNC) negatively impacts patient outcomes and is an important risk factor for recurrent and second primary tumors. Despite recommendations from several cancer societies, alcohol consumption remains a common problem in this population.

METHODS

A cross-sectional study was performed with the Alcohol Use Disorders Identification Test (AUDIT) Self-Report questionnaire. Patients with HNC completed surveys at pre-treatment and follow-up appointments every 3-6 months for at least 2-years after treatment.

RESULTS

796 surveys were available for analysis. Most participants were male (75.7%) and had either oropharyngeal (34.5%) or laryngeal (16.7%) cancer. The percentage of alcohol drinkers decreased from 56.1% at pre-treatment to 40.4% at 0-3 months post-treatment, but then increased and surpassed baseline levels by 24 + months post-treatment (64.4%, p = 0.0079). Concurrently, moderate drinkers (AUDIT = 1 - 3) decreased from 34.2% at pre-treatment to 25.2% at 0-3 months post-treatment, but then increased and surpassed baseline levels at 24 + months post-treatment (39.7%, p = 0.0129). Trends among heavy (AUDIT > 3), and heaviest (AUDIT > 6) drinkers were similar, but not statistically significant. At 24 + months post-therapy, we observed a statistically significant increase in female users (39.1% to 63.2%, p = 0.0213) and moderate drinkers < 55 years old (43.4% to 61.9%, p = 0.0184).

CONCLUSION

Alcohol consumption in survivors of HNC transiently decreases in the immediate months after treatment, but then increases and remains largely stable by 24 months. This pattern is particularly concerning and highlights the need for timely interventions.

A Prospective Real-World Multi-Center Study to Evaluate Progression-Free and Overall Survival of Radiotherapy with Cetuximab and Platinum-Based Chemotherapy with Cetuximab in Locally Recurrent Head and Neck Cancer

Simple Summary

Despite recent developments in immune checkpoint inhibitors, the treatment of locoregionally recurrent head and neck squamous cell cancer (HNSCC) remains challenging. Prospective data comparing re-irradiation with systemic treatment are not available. The SOCCER trial represents a prospective non-interventional multicenter trial that enrolled patients with locoregionally recurrent HNSCC treated with cetuximab in combination with re-radiotherapy or chemotherapy. A total of 192 patients were analyzed. Radiotherapy combined with cetuximab had superior progression-free and overall survival compared to chemotherapy with cetuximab. This highlights the high efficacy of local re-radiotherapy in combination with cetuximab in patients with locoregionally recurrent HNSCC.

Abstract

Treatment options of locoregional recurrent head and neck squamous cell cancer (HNSCC) include both local strategies as surgery or re-radiotherapy and systemic therapy. In this prospective, multi-center, non-interventional study, patients were treated either with platinum-based chemotherapy and cetuximab (CT + Cet) or re-radiotherapy and cetuximab (RT + Cet). In the current analysis, progression-free survival (PFS) and overall survival (OS) were compared in patients with locoregional recurrence. Four hundred seventy patients were registered in 97 German centers. After exclusion of patients with distant metastases, a cohort of 192 patients was analyzed (129 CT + Cet, 63 RT + Cet). Radiotherapy was delivered as re-irradiation to 70% of the patients. The mean radiation dose was 51.8 Gy, whereas a radiation dose of ≥60 Gy was delivered in 33% of the patients. Chemotherapy mainly consisted of cisplatin/5-flurouracil (40%) or carboplatin/5-flurouracil (29%). The median PFS was 9.2 months in the RT + Cet group versus 5.1 months in the CT + Cet group (hazard ratio for disease progression or death, 0.40, 95% CI, 0.27–0.57, p < 0.0001). Median OS was 12.8 months in the RT + Cet group versus 7.9 months in the CT + Cet group (hazard ratio for death, 0.50, 95% CI, 0.33–0.75, p = 0.0008). In conclusion, radiotherapy combined with cetuximab improved survival compared to chemotherapy combined with cetuximab in locally recurrent HNSCC.

Current Status of Human Papillomavirus-Related Head and Neck Cancer: From Viral Genome to Patient Care

Human papillomavirus (HPV) infection identified as a definitive human carcinogen is increasingly being recognized for its role in carcinogenesis of human cancers. Up to 38%–80% of head and neck squamous cell carcinoma (HNSCC) in oropharyngeal location (OPSCC) and nearly all cervical cancers contain the HPV genome which is implicated in causing cancer through its oncoproteins E6 and E7. Given by the biologically distinct HPV-related OPSCC and a more favorable prognosis compared to HPV-negative tumors, clinical trials on de-escalation treatment strategies for these patients have been studied. It is therefore raised the questions for the patient stratification if treatment de-escalation is feasible. Moreover, understanding the crosstalk of HPV-mediated malignancy and immunity with clinical insights from the proportional response rate to immune checkpoint blockade treatments in patients with HNSCC is of importance to substantially improve the treatment efficacy. This review discusses the biology of HPV-related HNSCC as well as successful clinically findings with promising candidates in the pipeline for future directions. With the advent of various sequencing technologies, further biomolecules associated with HPV-related HNSCC progression are currently being identified to be used as potential biomarkers or targets for clinical decisions throughout the continuum of cancer care.

It Takes Two to Tango: Patients' and Providers' Perspectives in Tobacco Cessation and Head/Neck Cancer

BACKGROUND

Tobacco cessation among patients with head/neck cancer continues to be challenging despite evidence that cessation improves treatment outcomes. The purpose of this study was to understand barriers/facilitators to tobacco cessation among patients with head/neck cancer and health care providers and to obtain perspectives toward the development of a patient-centered tobacco cessation intervention.

MATERIALS AND METHODS

In-depth qualitative interviews with 10 health care providers and 21 patients with head/neck cancer (12 inpatients and 9 outpatients) who were current or former smokers.

RESULTS

Health was a common motivator to quit among patients. Although most patients indicated that their health care provider asked and advised them to quit, they were unaware of cessation resources. Suggestions for a tobacco cessation program included involvement of former smokers, health care provider involvement/counseling, supporting written materials, and incorporating follow-up and family support. Health care providers identified patients' anger/frustration associated with the disease, social/demographic issues, and poor quality of life as the three most frequent challenges in treating patients. Although all providers reported asking about tobacco use, 70% emphasized a lack of formal training in tobacco cessation and lack of time. Their suggestions for a cessation program included having a "quarterback" responsible for this component with support from the entire health care team and continuity between outpatient and inpatient services to promote cessation, prevent relapse, and highlight the importance of follow-up and social support.

CONCLUSION

There is great interest and need, both from patients and providers, for tobacco cessation services in the oncology setting tailored for patients with head/neck cancer in the context of cancer care.

IMPLICATIONS FOR PRACTICE

Although the combination of pharmacotherapy and cognitive-behavioral intervention is the standard evidence-based treatment for tobacco dependence, it must be adapted to meet the needs and wants of patients and providers to be effective. This study provides an in-depth examination of such needs among patients with head and neck cancer and providers in the context of cancer care. Providers and patients emphasized the need of having a trained health care provider dedicated to providing tobacco cessation through seamless integration between outpatient and inpatient services as well as follow-up with an emphasis on family involvement throughout the process.
