A case of long-term survival after surgical resection for solitary adrenal recurrence of esophageal squamous carcinoma

Oesophageal cancer metastases: An observational study of a more aggressive approach

BACKGROUND

The prognosis for oesophageal carcinoma is poor, but once distant metastases emerge the prognosis is considered hopeless. There is no consistent protocol for the early identification and aggressive management of metastases.

AIM

To examine the outcome of a policy of active postoperative surveillance with aggressive treatment of confirmed metastases.

METHODS

A prospectively maintained database of 205 patients diagnosed with oesophageal carcinoma between 1998 and 2019 and treated with curative intent was interrogated for patients with metastases, either at diagnosis or on follow-up surveillance and treated for cure. This cohort was compared with incomplete clinical responders to neoadjuvant chemoradiotherapy (nCRT) who subsequently underwent surgery on their primary tumour. Overall survival was estimated using the Kaplan-Meier method, and the log-rank test was used to compare survival differences between groups.

RESULTS

Of 205 patients, 11 (5.4%) had metastases treated for cure (82% male; median age 60 years; 9 adenocarcinoma and 2 squamous cell carcinomas). All had undergone neoadjuvant chemotherapy or chemoradiotherapy, followed by surgery in all but 1 case. Of the 11 patients, 4 had metastatic disease at diagnosis, of whom 3 were successfully downstaged with nCRT before definitive surgery; 2 of these 4 also developed oligometastatic recurrence and were treated with curative intent. Following definitive treatment, 7 had treatment for metachronous oligometastatic disease; 5 of whom underwent metastasectomy (adrenal × 2; lung × 2; liver × 1). The median overall survival was 10.9 years [95% confidence interval (CI): 0.7-21.0 years], which was statistically significantly longer than incomplete clinical responders undergoing surgery on the primary tumour without metastatic intervention [n = 62; median overall survival = 1.9 (95%CI: 1.1-2.7; P = 0.012]. The cumulative proportion surviving 1, 3, and 5 years was 100%, 91%, and 61%, respectively compared to 71%, 36%, and 25% for incomplete clinical responders undergoing surgery on the primary tumour who did not undergo treatment for metastatic disease.

CONCLUSION

Metastatic oesophageal cancer represents a unique challenge, but aggressive treatment can be rewarded with impressive survival data. In view of recent advances in targeted therapies, intensive follow-up may yield a greater number of patients with curative potential and thus improved long-term survival.

Laparoscopic management of isolated metachronous adrenal metastases in a patient with esophageal cancer: a case report

Background

The presence of isolated metachronous adrenal metastasis in patients with esophageal cancer is rare. There is significant controversy regarding the management of such patients. Adrenal metastasectomy has been shown to be of benefit in some reports. Minimally invasive approach, although the gold standard for adrenalectomy, has not been used commonly in a postesophagectomy setting owing to the anticipated technical difficulties. We describe one such case wherein this approach helped in early recovery and long-term survival.

Case presentation

A 59-year-old male of Asian ethnicity presented with an isolated left adrenal nodule, 3 years after an Ivor Lewis esophagectomy for a lower esophageal adenocarcinoma. The biopsy of the nodule was suggestive of metastatic adenocarcinoma. The patient underwent laparoscopic excision of the left adrenal gland.

Conclusion

Adrenal metastasectomy, in postesophagectomy patients can provide good oncological control. Laparoscopic approach, though technically challenging, can provide results equivalent to those of open surgery, albeit with less morbidity.

Solitary recurrence at intercostal drain site in oesophageal adenocarcinoma

56 year old gentleman was evaluated for dysphagia and diagnosed with oesophageal adenocarcinoma and had undergone Transhiatal Oesophagectomy elsewhere, pT3N0, but had defaulted adjuvant treatment. He presented 15 months later to us with nodule at left intercostal drain (ICD) drain site. Positron Emission Tomography (PET) scan showed it to be single site metastasis and he underwent wide excision, followed by six cycles of chemotherapy. He is symptom free and on regular follow up for a period of ten months. Oesophageal cancer although with poor prognosis can be considered for metastatectomy after considering the disease free interval, site of recurrence and histological factors in carefully selected patient.

Oligometastatic recurrence of an oesophageal adenocarcinoma at a chest drain site following radical treatment: palliative treatment or resection?

A 62-year-old female patient diagnosed with oesophageal adenocarcinoma underwent radical treatment consisting of neoadjuvant chemotherapy and oesophagectomy with no major complications. Eleven months later, she re-presented with a mass at one of the chest drain sites. A PET-CT scan and biopsy demonstrated this to be a single recurrence of the oesophageal adenocarcinoma. Excision of the metastatic lesion was considered as per metachronous single site metastasis. However, the operation was postponed due to acute kidney injury. Restaging after 6 weeks revealed progressive metastatic disease. The patient underwent palliative therapy and passed away soon after. Oesophageal cancer recurrence has a very poor prognosis, and factors such as the disease-free interval, site of recurrence and tumour pathological factors must be considered when stratifying for suitability for metastasectomy. A period of watchful waiting followed by restaging is essential to rule out patients with indolent metastatic disease.
