486. FOR SYNCHRONOUS ESOPHAGEAL CARCINOMA AND PULMONARY LESION: IS IT APPROPRIATE TO PERFORM COMBINED RESECTION?

Abstract Background Reports on esophageal cancer with concurrent lung lesion cases are rare and mostly individual cases. Furthermore, the safety and feasibility of combined resection for patients with synchronous pulmonary lesions and esophageal cancer had always been a controversial topic. In the current study, we retrospectively analyzed the clinical data of patients who underwent simultaneous surgical resection for esophageal cancer with concurrent lung lesions, and explored their clinical characteristics, treatment outcomes, especially postoperative complications and prognosis. Method Patients who underwent esophagectomy between February 2009 and December 2022 were retrospectively reviewed at our center, and those with combined lung resection at the same setting were matched in a 1:1 propensity score matched (PSM) ratio to esophagectomy-alone patients. The main postoperative complications (including pneumonia, anastomotic leakage, pleural effusion, and other complications) and overall survival were compared. Results Of the 7152 esophagectomies, 222 cases of combined resection for synchronous pulmonary lesion (including 105 pneumatoceles, 71 benign nodules, and 46 malignant nodules) were eligible, and 1:1 ratio PSM esophagectomy-alone patients were matched. Wedge resection was the most frequent procedures (181, 81.5%). No significant differences were found in the incidence of postoperative complication between combined resection and esophagectomy-alone: pneumonia (21.2% vs. 20.7%), anastomotic leakage (7.2% vs. 6.3%), pleural effusion (15.3% vs. 13.1%). Moreover, different type of pulmonary lesions and extent of pulmonary resection also unaffected the incidence of postoperative complications. Survival analysis showed no significant difference for combined surgery or esophagectomy-alone. Conclusion In this large sample size study, combined resection dose not elevate the incidence of postoperative complications and weaken the overall survival for patients with synchronous esophageal carcinoma and pulmonary lesion. Therefore, for patients with clinically diagnosed esophageal cancer combined with lung lesions requiring surgery, the risk of concurrent resection may be acceptable.

Risk factors and survival analysis for synchronous esophageal carcinoma in patients with hypopharyngeal carcinoma

Objective: To investigate the risk factors and survival status of hypopharyngeal carcinoma with synchronous second primary carcinoma of the esophagus. Methods: One hundred and sixty patients with newly diagnosed hypopharyngeal carcinoma from January 2009 to December 2012 were retrospectively reviewed. The clinical data, tumor-related information and follow-up results were collected and analyzed. Results: Forty-three synchronous esophageal carcinomas (27%) were detected in 160 patients with hypopharyngeal carcinoma, and most patients (72%) were at an early stage. On univariate analysis, the median age of less than 55 years old (χ(2)=4.525, P=0.033), excessive alcohol consumption (χ(2)=6.942, P=0.008) and invasion site more than 3 anatomical regions (χ(2)=21.503, P=0.000) had a significant correlation with the occurrence of synchronous esophageal carcinomas. Multivariate analysis showed that excessive alcohol consumption (OR=4.787, P=0.029) and invasion site more than 3 anatomical regions (OR=14.391, P=0.000) were independent risk factors. The median survival time was 26 months in 43 patients with synchronous esophageal carcinomas, which was significantly lower than that (58 months) in patients without secondary primary esophageal carcinomas (χ(2)=11.981, P=0.001). Conclusions: There is a high incidence of synchronous esophageal carcinoma in hypopharyngeal carcinoma patients, affecting the prognosis of hypopharyngeal carcinoma. Surveillance for esophageal carcinomas in patients with hypopharyngeal carcinoma, especially in excessive alcohol drinkers, is warranted.

A rare case of esophageal metastasis from pancreatic ductal adenocarcinoma: a case report and literature review.

PurposeWe report a very unique case of an esophageal metastasis from a pancreatic ductal adenocarcinoma (PDAC) primary.MethodsAfter obtaining consent from the patient, all relevant records of the case were obtained and retrospectively reviewed.ResultsAt presentation, the patient was diagnosed with synchronous pancreatic and esophageal cancer. He received six months of neoadjuvant therapy including FOLFIRINOX (5-fluorouracil, leucovorin, irinotecan, and oxaliplatin) and stereotactic body radiation therapy (SBRT) to the pancreatic tumor followed by a combined pancreaticoduodenectomy and Ivor Lewis esophagectomy. Review of the final esophageal specimen revealed normal overlying squamous mucosa with an underlying focus of metastatic PDAC. The patient remains alive with no evidence of disease 17 months from surgery and 25 months from diagnosis.ConclusionsDifferentiating an esophageal metastasis from a PDAC primary versus a synchronous esophageal carcinoma is very difficult despite state-of-the-art diagnostic techniques performed at a high-volume tertiary cancer center. Extensive evaluation and continued follow-up of PDAC patients presenting with a synchronous esophageal lesion in a multidisciplinary setting may help ensure efficient and accurate management. In our case, neoadjuvant FOLFIRINOX and SBRT to the primary PDAC tumor followed by surgery has been an effective approach for this patient.

Is routine triple endoscopy for head and neck carcinoma patients necessary in light of a negative chest computed tomography scan?

The objective of the current study was to analyze the results obtained by triple endoscopy during the initial evaluation of a primary carcinoma of the head and neck. A total of 487 patients with a squamous cell carcinoma of the head and neck was studied. None of the patients had evidence of metastasis or a second primary tumor on the thoracic computed tomography (CT) scan or chest X-ray. All patients underwent a triple endoscopy including nasopharyngoscopy, laryngoscopy, pharyngoscopy, bronchoscopy, and esophagoscopy. A synchronous primary invasive carcinoma of the lung and esophagus was diagnosed in 5 patients (1%) and 10 patients (2%), respectively. In addition, nine lesions were considered to be a regional extension of the primary tumor to the esophagus, and nine in situ carcinomas were observed. It is interesting to note that a significant correlation was found between the risk of a second synchronous esophageal carcinoma and the initial location of the primary head and neck carcinoma (P = 0.002, chi-square test). Esophageal carcinoma was observed in 1.3% of the patients with an oropharyngeal tumor, 2% of the patients with a laryngeal tumor, none of the patients with a tumor of the oral cavity, and 9.2% of the patients with a hypopharyngeal tumor. The role of bronchoscopy and esophagoscopy in the presence of a normal thoracic CT scan has been questioned because of the relatively low incidence of a second esophageal and/or lung primary tumor. Nonetheless, based on the same incidence criterion, it appears reasonable to schedule a routine esophagoscopy for those patients with a squamous cell carcinoma of the hypopharynx.

Circumferential pharyngolaryngectomy with total esophagectomy for locally advanced carcinomas.

Forty-nine cases of circumferential pharyngolaryngectomy with total esophagectomy (PLTE) done between 1982 and 1996 were studied retrospectively. These procedures were performed for advanced squamous cell tumors of the superior esophageal sphincter (n = 23), for hypopharyngeal tumors with synchronous esophageal carcinoma (n = 15), and for hypopharyngeal tumors extensively invading the cervical esophagus (n = 11). Ninety-six percent of the patients had T3-4 lesions, and it was impossible to use a free jejunal graft reconstruction. Patients underwent primary surgery in 70% of the cases, and salvage surgery (after failure of chemoradiotherapy) in 30%. In most patients, esophagectomy was performed without thoracotomy (n = 45). Resection was curative (R0) in 70% of the cases, in spite of lymph node invasion in 94%. Reconstruction of the digestive tract was achieved with the stomach in 33 patients (67%) or with the colon in 16 patients (33%). Before 1989, postoperative mortality was high, was correlated with the high frequency of palliative surgery, and resulted in unsatisfactory survival results (overall 5-year survival rate of 7%). After 1989, as a result of better selection of patients and appropriate training of our team, postoperative mortality decreased from 33% to 10%, R1-2 resections decreased from 39% to 26%, and a 3-year overall survival rate of 28% was obtained for the last 25 patients, all of whom were able to eat without difficulty. These results are superior to the survival rates and functional results obtained with radiochemotherapy alone for such advanced tumors, even though the voice is preserved with radiochemotherapy alone. PLTE for advanced pharyngeal or cervical esophageal tumors is the best treatment currently available, but it is indicated only in very selected cases: when it is technically impossible to perform reconstruction with a free jejunal graft after circumferential pharyngolaryngectomy; as primary surgery, rather than as salvage surgery following chemoradiotherapy; after careful preoperative morphologic and endoscopic assessment of the extent of the tumor; and in patients able to tolerate a thoracotomy for an esophagectomy with lymphadenectomy. Selection according to these guidelines should improve results.

A PRIMARY RESECTED CASE OF SYNCHRONOUS SQUAMOUS CARCINOMA OF THE THORACIC ESOPHAGUS AND HEPATOCELLULAR CARCINOMA

The simultaneous occurrence of esophageal and hepatic tumors is rare. The operative procedure and timing are controversial. Recently we experienced a case of such double cancer which was successfully cured by simultaneous resection. A 70-year-old man was pointed out of an esophageal abnormality by UGI at a periodic examination, and was admitted to the hospital with an esophageal carcinoma in the distal esophagus which was diagnosed by endoscopic examination. There were previous histories of hemothor-ax, bronchoectasia and liver cirrhosis (HCV). On admission abdominal ultrasonography and computed tomography revealed a hepatic tumor, 3cm in diameter, at the lateral segment (S3). His serum alpha-fetoprotein (AFP) level was elevated (37.6ng/ml). The patient was diagnosed as synchronous esophageal carcinoma and HCC. After the severity of his respiratory and liver functions was assessed, transthoracic subtotal esophagectomy and partial resection of the liver were primarily performed. Histopathologic examination confirmed the relative curative resection of the esophageal carcinoma and curative resection of HCC. The increased serum AFP level was normalized after the operation. No recurrent sign has been found as of 15 months after this surgical management.

Prevalence and clinicopathologic features of multiple squamous cell carcinoma of the esophagus.

The occurrence of independent synchronous esophageal carcinoma in patients with grossly invasive esophageal cancer (GEC) is well known. Although multiple primary carcinoma of the esophagus is not uncommon, the exact prevalence is controversial, and its clinicopathologic features remain relatively unknown. Fifty-four patients with squamous cell GEC who underwent transthoracic esophagectomy with systematic lymphadenectomy between 1987 and 1991 at the Institute for Digestive Diseases, Belgrade University Clinical Center, were included in the study. Detailed histopathologic examination of the esophagus resected for squamous cell carcinoma was performed in 54 patients and revealed 17 patients (31%) with associated cancer independent of the main tumor. The second lesion was significantly less invasive than the main tumor. There was no significant difference (P = 0.06) in sex, age, main tumor site, tumor differentiation, tumor diameter, lymph node involvement, or tumor stage between patients with multiple cancer and patients with solitary cancer, but there was a significant difference in the depth of invasion (P < 0.01). The tumor stage in patients with multiple cancer was determined by the main tumor stage and was not influenced by the associated lesion. The prevalence of multiple primary cancer of the esophagus is lower in other reports than in this series. The patients in this study had significantly more invasive main tumors. It seems likely that a higher prevalence of multiple cancer may be expected in patients with advanced main tumor penetration. These results support the concept that the entire esophagus may be considered as one entity of field cancerogenesis.
