The use of short segment free jejunal transfer as salvage surgery for cervical esophageal and hypopharyngeal cancer

Surgical outcomes of reconstruction using the gastric tube and free jejunum for cervical esophageal cancer: analysis using the National Clinical Database of Japan

BACKGROUND

Cervical esophageal cancer accounts for a small proportion of all esophageal cancers. Therefore, studies examining this cancer include a small patient cohort. Most patients with cervical esophageal cancer undergo reconstruction using a gastric tube or free jejunum after esophagectomy. We examined the current status of postoperative morbidity and mortality of cervical esophageal cancer based on big data.

METHODS

Based on the Japan National Clinical Database, 807 surgically treated patients with cervical esophageal cancer were enrolled between January 1, 2016, and December 31, 2019. Surgical outcomes were retrospectively reviewed for each reconstructed organ using gastric tubes and free jejunum.

RESULTS

The incidence of postoperative complications related to reconstructed organs was higher in the gastric tube reconstruction (17.9%) than in the free jejunum (6.7%) for anastomotic leakage (p < 0.01), but not significantly different for reconstructed organ necrosis (0.4% and 0.3%, respectively). The incidence rates of overall morbidity, pneumonia, 30-day reoperation, tracheal necrosis, and 30-day mortality using these reconstruction methods were 64.7% and 59.7%, 16.7% and 11.1%, 9.3% and 11.4%, 2.2% and 1.6%, and 1.2% and 0.0%, respectively. Only pneumonia was more common in the gastric tube reconstruction group (p = 0.03), but was not significantly different for any other complication.

CONCLUSIONS

The incidence of overall morbidities and reoperation, especially anastomotic leakage after gastric tube reconstruction, suggested a necessity for further improvement. However, the incidence of fatal complications, such as tracheal necrosis or reconstructed organ necrosis, was low for both reconstruction methods, and the mortality rate was acceptable as a means of radical treatment.

Induction chemotherapy for the individualised treatment of hypopharyngeal carcinoma with cervical oesophageal invasion: a retrospective cohort study

Background

This study aimed to evaluate the potential of induction chemotherapy as an indicator of the management of advanced hypopharyngeal carcinoma with cervical oesophageal invasion.

Methods

Sixty-eight patients admitted to our hospital between February 2003 and November 2016 with stage IVB hypopharyngeal carcinoma with cervical oesophageal invasion were retrospectively analysed. Patients were divided into two groups according to the treatment they selected following an explanation of the different treatments available. Patients in group A received induction chemotherapy and had (1) complete/partial remission following chemotherapy and radiotherapy/concurrent chemoradiotherapy or (2) stable disease following chemotherapy and surgery. Patients in group B underwent surgery followed by adjuvant radiotherapy/concurrent chemoradiotherapy. Survival analyses were performed using the Kaplan–Meier method, and differences between the groups were evaluated using the log-rank test. Laryngeal and oesophageal retention rates were compared using the cross-tabulation test.

Results

The 3- and 5-year overall survival rates were 22.86% and 11.43% in group A and 24.25% and 6.06% in group B, respectively (all P > 0.05). The laryngeal and oesophageal retention rates were 40.0% and 74.3% in group A and 0.0% and 27.3% in group B, respectively (all P < 0.01). There was no statistically significant difference in the incidence of post-operative complications between the two groups (group A 8.6%, group B 12.1%; P > 0.05).

Conclusions

Induction chemotherapy may be an appropriate first choice to ensure laryngeal and oesophageal preservation in the individualised treatment of advanced hypopharyngeal carcinoma with cervical oesophageal invasion.

Oncological results of salvage treatment in patients with hypopharyngeal carcinoma

INTRODUCTION AND OBJECTIVE

The aim of this study is to analyse the variables related to the feasibility of salvage surgery with radical intention in patients with a local recurrence of hypopharyngeal carcinoma, and to evaluate the oncological performance of this type of surgery.

METHODS

Retrospective study of 96 patients with hypopharyngeal carcinoma with local tumour recurrence RESULT: Only 27 patients (28.1%) were considered for surgical salvage treatment. The variables related to feasibility of salvage surgery were non-surgical initial treatment of the tumour and a disease-free interval greater than 6 months. All 69 patients non-candidates for salvage surgery died as a result of tumour progression in a period of less than 2.5 years. The 5-year disease-specific survival rate for the patients treated with salvage surgery was 39.5%. The only variable significantly related to disease-specific survival was the status of the resection margins. Patients with extensive tumour recurrence (rT3-T4) or with simultaneous nodal involvement had a lower survival rate, but the differences did not reach statistical significance.

CONCLUSION

Only 28% of the patients with hypopharyngeal carcinoma with local recurrence of the tumour were eligible for salvage surgery with radical intention. The patients treated with salvage surgery had a 5 -year disease-specific survival of 39.5%.

Comparison of curative surgery and definitive chemoradiotherapy as initial treatment for patients with cervical esophageal cancer

Esophagectomy and definitive chemoradiotherapy are recognized standard initial treatment modalities for cervical esophageal cancer. The goal of this study was to compare the treatment outcomes of curative surgery with those of chemoradiotherapy in patients who had potentially resectable tumor and who were candidates for surgery. We evaluated the data from 49 consecutive patients who were diagnosed with potentially resectable cervical esophageal cancer and who were deemed candidates for surgery. Thirteen patients were included in the surgery group, and 36 patients were included in chemoradiotherapy group. Baseline characteristics were balanced between the two groups. In the chemoradiotherapy group, the complete response rate was 58.3%. There was no significant difference in 5-year overall survival when comparing the surgery group and the chemoradiotherapy group (surgery, 60.6%; chemoradiotherapy, 51.4%; P = 0.89). In the chemoradiotherapy group, of the 15 patients who failed to respond to initial treatment, 11 patients subsequently underwent salvage surgery. In conclusion, curative surgery and chemoradiotherapy as initial treatment for cervical esophageal cancer have comparable survival outcomes. Chemoradiotherapy should be selected as the initial larynx-preserving treatment for patients with cervical esophageal cancer although chemoradiotherapy non-responders require additional treatment, including salvage surgery.

Comparison of Salvage Total Pharyngolaryngectomy and Cervical Esophagectomy Between Hypopharyngeal Cancer and Cervical Esophageal Cancer

BACKGROUND

Total pharyngolaryngectomy and cervical esophagectomy (TPLCE) after chemoradiotherapy remains a challenge because of the high rate of complications and few available data on outcomes and safety. The purpose of this study was to evaluate the clinical significance of salvage TPLCE and to compare treatment outcomes between hypopharyngeal cancer and cervical esophageal cancer.

METHODS

Data from 37 consecutive patients who were diagnosed with potentially resectable hypopharyngeal and cervical esophageal cancer after chemoradiotherapy were retrospectively analyzed. The survival and surgical outcomes were investigated between the hypopharyngeal cancer and cervical esophageal cancer groups.

RESULTS

Twenty-six patients were included in hypopharyngeal cancer group and 11 patients were included in cervical esophageal cancer group. The baseline characteristics were balanced between the two groups. Compared to the hypopharyngeal cancer group, the cervical esophageal cancer group had significantly more frequent tracheal-related complications (p < 0.05) and stronger association of distal margin of the cervical esophagus and radiation field with tracheal ischemia after salvage surgery.

CONCLUSIONS

Salvage TPLCE can offer the exclusive chance of prolonged survival. Association of tracheal ischemia with salvage TPLCE was seen more frequently for cervical esophageal cancer. Therefore, the indication for salvage TPLCE must be carefully considered to maintain the balance between curability and safety.
