Screening for synchronous esophageal second primary tumors in patients with head and neck cancer

Association of esophageal squamous cell carcinoma with head and neck cancer

BACKGROUND AND OBJECTIVES

Esophageal squamous cell carcinomas (ESCC) are often accompanied by head and neck squamous cell carcinoma (HNSCC) and vice versa. Our study aimed to describe the prevalence of HNSCC in patients with ESCC, the chronology of appearance and the impact on survival.

METHODS

A retrospective review was carried out through a computerized database of patients diagnosed with ESCC at Hospital Clinic of Barcelona between January 1999 and June 2019. Demographic data, date of ESCC diagnosis, survival time, primary tumor location, diagnosis of HNSCC and chronological relationship were recorded.

RESULTS

A total of 231 patients with ESCC confirmed histologically were included in the study with a median age of 64 years (IQR, 56.0-72.0), and 178 (77%) were male. The majority of the patients had a history of smoking and alcohol consumption (69.7% and 60.6%, respectively). The predominant location of ESCC was the middle esophagus (n=124, 53.7%). Forty-one patients (17.7%) had HNSCC: 21 (51.2%) were previous, 14 (34.1%) synchronous and 6 (14.6%) metachronous. All the patients were followed and 196 (84.8%) died with a median survival time of 19 months (IQR, 7-66). There were not statistically significant differences among the living patients and the deceased.

CONCLUSIONS

In our setting, a 17.7% of patients with ESCC have an associated HNSCC with no significant differences in survival between patients with both ESCC and HNSCC compared to those with only ESCC. However, the implementation of a screening program could allow the detection of a second primary tumor at early stages.

The incidence of esophageal second primary cancer in head and neck cancer patients

This study aims to investigate the correlation between esophageal second primary neoplasm (ESPN) in head and neck cancers. Panendoscopy findings of ESPN can guide clinicians in timely interventions and improve patients' outcomes. We performed a retrospective cohort study in Linkou Chang Gung Memorial Hospital, and 365 patients who met the criteria from 2015 to 2021 were enrolled. We collected the lifestyle habits and panendoscopy report after the HNC was diagnosed. Of 365 HNC patients, 37 (10.1%) had ESPNs, which included low dysplasia, high dysplasia, squamous cell carcinoma in situ and squamous cell carcinoma. We found that alcohol (P = .004) and areca-quids (AQs) consumption (P = .003) had significant differences in different HNC subsites. Oral cavity cancers had the highest association with alcohol and AQs consumption. Hypopharyngeal cancer has the highest ESPN incidence with highest odds ratio (OR = 13.3, P < .001), followed by oropharynx, larynx, and oral cavity. In addition, we found that alcohol (P = .002) and cigarette consumption (P = .040) were associated with the ESPN development. Other panendoscopy findings such as gastroesophageal reflux disease, esophageal mucosa break, gastritis ulceration, and gastritis showed insignificant correlations with the occurrence of ESPN. Half of the ESPN were found within 24 months after the diagnosis of HNC, especially for hypopharyngeal cancer, in which ESPN even occurs within 12 months of the diagnosis of primary tumor. Routine panendoscopy for patients with HNC is highly advised, and our study suggests having intensive surveys in the first 24 months after the diagnosis of primary HNC; especially for hypopharyngeal cancer. This study was reported in strict compliance with the strengthening the reporting of observational studies in epidemiology (STROBE) guideline.

Endoscopic screening of the upper gastrointestinal tract for second primary tumors in patients with head and neck cancer in a Western country

BACKGROUND

Patients with head and neck squamous cell carcinoma (HNSCC) can develop second primary tumors (SPTs) in the esophagus. Endoscopic screening could lead to detection of SPTs at early stages and improve survival.

METHODS

We performed a prospective endoscopic screening study in patients with curably treated HNSCC diagnosed between January 2017-July 2021 in a Western country. Screening was performed synchronously (< 6 months) or metachronously (≥ 6 months) after HNSCC diagnosis. Routine imaging for HNSCC consisted of flexible transnasal endoscopy with positron emission tomography/computed tomography or magnetic resonance imaging, depending on primary HNSCC location. The primary outcome was prevalence of SPTs, defined as presence of esophageal high grade dysplasia or squamous cell carcinoma.

RESULTS

202 patients (mean age 65 years, 80.7 % male) underwent 250 screening endoscopies. HNSCC was located in the oropharynx (31.9 %), hypopharynx (26.9 %), larynx (22.2 %), and oral cavity (18.5 %). Endoscopic screening was performed within 6 months (34.0 %), 6 months to 1 year (8.0 %), 1-2 years (33.6 %), and 2-5 years (24.4 %) after HNSCC diagnosis. We detected 11 SPTs in 10 patients (5.0 %, 95 %CI 2.4 %-8.9 %) during synchronous (6/85) and metachronous (5/165) screening. Most patients had early stage SPTs (90 %) and were treated with curative intent with endoscopic resection (80 %). No SPTs in screened patients were detected with routine imaging for HNSCC before endoscopic screening.

CONCLUSION

In 5 % of patients with HNSCC, an SPT was detected with endoscopic screening. Endoscopic screening should be considered in selected HNSCC patients to detect early stage SPTs, based on highest SPT risk and life expectancy according to HNSCC and comorbidities.

McKeown Versus Ivor-Lewis Esophagectomy for Patients with a History of Total Pharyngolaryngectomy: A Comparison Study

BACKGROUND

Oncologic esophagectomy in patients with a history of total pharyngolaryngectomy (TPL) is challenging. There are two different esophagectomy procedures: total esophagectomy with cervical anastomosis (McKeown) and subtotal esophagectomy with intrathoracic anastomosis (Ivor-Lewis). Differences in outcomes between McKeown and Ivor-Lewis esophagectomies for patients with this history remain unclear.

METHODS

We retrospectively reviewed 36 patients with a history of TPL who underwent oncologic esophagectomy and compared the clinical outcomes between the procedures.

RESULTS

Twelve (33.3%) and 24 (66.7%) patients underwent McKeown and Ivor-Lewis esophagectomies, respectively. McKeown esophagectomy was more frequently performed for the supracarinal tumors (P = 0.002). Other baseline characteristics, including the history of radiation therapy, were comparable between the groups. Postoperatively, the incidences of pneumonia and anastomotic leakage were higher in the McKeown group than in the Ivor-Lewis group (P = 0.029 and P < 0.001, respectively). Neither tracheal necrosis nor remnant esophageal necrosis was observed. The overall and recurrence-free survival rates were comparable between the groups (P = 0.494 and P = 0.813, respectively).

CONCLUSIONS

When performing esophagectomy for patients with a history of TPL, if it is oncologically acceptable and technically available, Ivor-Lewis is preferable over McKeown esophagectomy for avoiding postoperative complications.

Effect of esophageal cancer screening on mortality among patients with oral cancer and second primary esophageal cancer in Taiwan

OBJECTIVE

Oral and esophageal cancer are the fourth and fifth leading causes of cancer deaths among men in Taiwan. Despite a good prognosis for oral cavity cancer patients, survival is worse for those who develop second primary esophageal cancer. There remains no consensus regarding early prevention of potential second primary esophageal cancer in patients with oral cavity cancer. Our study aimed to compare 5-year mortality between endoscopically screened and non-screened patients with oral cavity cancer and second primary esophageal cancer.

MATERIALS AND METHODS

This study identified patients with incident oral cavity cancer and second primary esophageal cancer during 2004 and 2013 using the Taiwan Cancer Registry and National Health Insurance Research Database. We compared 5-year mortality from the second primary esophageal cancer diagnosis date between screened and non-screened groups of patients with oral cavity cancer and second primary esophageal cancer.

RESULTS

A total of 217 screened and 305 non-screened oral cavity cancer patients with second primary esophageal cancer were studied. Endoscopic screening significantly improved early detection of second primary esophageal cancer (adjusted odds ratio: 0.34, 95 % confidence interval [CI]: 0.23-0.49) and reduced all-cause mortality (adjusted hazard ratio: 0.80; 95 % CI: 0.66-0.98).

CONCLUSIONS

Oral cavity cancer patients with second primary esophageal cancer may have worse overall survival than those without. Early detection of second primary esophageal cancer is a crucial mediator between endoscopic screening and mortality. Endoscopic screening after the diagnosis of incident oral cavity cancer significantly increased early detection and reduced all-cause mortality.

Screening for head and neck tumors in patients with esophageal squamous cell carcinoma and vice versa: a nationwide survey among medical specialists

Background and study aims  Retrospectively, minimally 5% of patients with esophageal squamous cell carcinoma (ESCC) and 11 % with head and neck squamous cell carcinoma (HNSCC) in Western countries developed a second primary tumor (SPT). SPT screening in ESCC and HNSCC patients is not implemented routinely in daily practice in many Western countries. This study aimed to assess medical specialist knowledge and opinions regarding screening for head and neck SPTs (HNSPTs) in ESCC patients and vice versa in the Netherlands. Methods  A nationwide survey among gastroenterologists and head and neck (HN) surgeons was conducted between December 2020 and March 2021. The survey consisted of 27 questions and focused on knowledge of medical specialists of the prevalence and opinions toward implementing screening for HNSPTs in ESCC patients and vice versa. Results  One hundred twenty-eight gastroenterologists (20.5 %) and 31 HN surgeons (50.0 %) completed the survey. The expected median prevalence of HNSPTs in ESCC was 7.0 % (interquartile range [IQR]: 5.0-15.0) among gastroenterologists and 5.0 % (IQR:3.0-8.0) among HN surgeons. For ESPTs in HNSCC, the expected median prevalence was 9.5 % (IQR: 5.0-12.0) among gastroenterologists and 4.0 % (IQR: 2.0-5.0) among HN surgeons. Screening for HNSPTs and ESPTs was considered promising by 35.2 % and 39.6 %, respectively, which increased to 54.7 % of the specialists after providing incidence data on SPTs. Of the HN surgeons, 41.3 % felt they were as capable as gastroenterologists of performing esophageal screening. Conclusions  This Dutch nationwide survey revealed a lack of knowledge and different perspectives among specialists about screening to detect SPTs in ESCC and HNSCC patients. Adequate education seems essential to increase awareness among specialists and improve SPT detection, independent of the need for implementation of screening for SPTs in ESCC and HNSCC patients.

Endoscopic Screening for Second Primary Tumors of the Esophagus Among Head and Neck Cancer Patients

Malignancies of the head and neck (HN) region and esophagus are among the most common cancers worldwide. Due to exposure to common carcinogens and the theory of field cancerization, HN cancer patients have a high risk of developing second primary tumors (SPTs). In our review of 28 studies with 51,454 HN cancer patients, the prevalence of SPTs was 12%. The HN area is the most common site of SPTs, followed by the lungs and esophagus, and 13% of HN cancer patients have been reported to have esophageal high-grade dysplasia or invasive carcinoma. The prognosis of HN cancer patients with concomitant esophageal SPTs is poor, and therefore identifying esophageal SPTs as early as possible is of paramount importance for risk stratification and to guide the treatment strategy. Image-enhanced endoscopy, especially using narrow-band imaging endoscopy and Lugol’s chromoendoscopy, has been shown to improve the diagnostic performance in detecting esophageal neoplasms at an early stage. Moreover, the early detection and minimally invasive endoscopic treatment of early esophageal neoplasm has been shown to improve the prognosis. Well-designed prospective studies are warranted to establish appropriate treatment and surveillance programs for HN cancer patients with esophageal SPTs.
