Inoperable nonmetastatic squamous cell carcinoma of the esophagus managed by concomitant chemotherapy (5-fluorouracil and cisplatin) and radiation therapy.

Thirty-five patients with nonmetastatic squamous cell carcinoma of the esophagus were treated with chemotherapy (5-fluorouracil, cisplatin) and concomitant split-course radiation therapy. All of the patients presented with dysphagia. Treatment consisted of two courses of chemotherapy with 5-FU (1 g/m2/day in continuous infusion for 5 days [days 1 to 5 and days 29 to 33] ) and cisplatin (70 mg/m2 intravenous bolus at days 2 and 30). Radiation therapy was concomitant in two courses delivering 20 Gy in 5 days (days 1 to 5 and days 29 to 33). On the first day of treatment, endoscopic peroral dilation or Nd-YAG laser therapy was usually carried out. At the end of the treatment, all of the patients were capable of oral nutrition. Histoendoscopic confirmation was made 8 weeks after the beginning of the therapy. Twenty-five of the 35 patients had a complete response with negative biopsy findings. There was only one serious complication (fatal myelosuppression) in the only patient who received more than two courses of chemotherapy. Sixteen patients died and 19 were still alive at 3 to 42 months after the beginning of treatment. Overall median survival for the 35 patients is 17 months. Actuarial survival was 55 +/- 18% at 1 year and 41 +/- 21% at 2 years. The median survival of the Stage I and II patients is 28 months. These results confirm that concomitant chemoradiotherapy is capable of producing a very high histoendoscopic complete response rate and improved 1-year and 2-year survival. The use of concentrated split-course radiotherapy enabled the authors to reduce the total length of the treatment to two periods of 5 days, with results that are similar to previous studies using classic radiotherapy for a 5-week to 7-week period.

[Approaching the posterior wall of the aortic arch. Temporary division of the innominate artery].

Two cases of wound affecting the posterior wall of the aortic arch are reported. One wound occurred during mediastinoscopy, the other was caused by a bullet. During surgery under extracorporeal circulation, the approach and repair of the wounds was greatly facilitated by temporary division of the innominate artery: the ascending and horizontal portions of the aorta could be tilted to the left, giving a very satisfactory access to the posterior wall of the arch. The innominate artery was easily repaired, without neurological complications. The authors insist on the convenience of this technique to approach not only the aortic arch but also various mediastinal organs, such as the tracheal bifurcation, the right branch of the pulmonary artery and the roof of the left atrium.

[Gastric esophagoplasty in the treatment of cancer of the esophagus].

Between March 1982 and December 1987, 112 patients with oesophageal cancer were treated by gastroplasty following oesophagectomy to restore gastrointestinal continuity. This technique was used in all oesophageal cancers regardless of their site, with the exception of paryngo-oesophageal and oesophago-cardio-fundal cancers. The overall mortality of 12.5% fell to below 6% during the last two years. The postoperative course was straightforward in 54.5% of cases. The most frequent complications were respiratory tract complications (19 cases of ARDS out of 112 patients, i.e. 17%) and fistulae at the oesophago-gastric anastomosis (9 cases out of 112, i.e. 8%). The secondary complications were dominated by anastomotic stenoses (19/98, i.e. 19.3%).

[Gastroesophageal reflux and respiratory manifestations: diagnostic approach, therapeutic indications and results].

The authors report a study of 140 patients presenting with a non-allergic respiratory tract disease (121 cases of asthma--19 cases of spasmodic cough). Gastro-oesophageal reflux was detected by 24-hour pHmetry in 86 of these patients. In 34 of them (i.e. 40% of cases), the gastro-oesophageal reflux appeared to be responsible for the initial respiratory tract symptoms. These 34 patients were submitted to a therapeutic trial of high dose anti-H2 therapy for at least two months. Only those patients in whom a marked improvement or even complete resolution of the respiratory tracts symptoms was observed underwent anti-reflux surgery. Out of the 13 patients undergoing surgery, there were two failures and 11 good results after a follow-up of more than 18 months.

[Surgical treatment of benign laryngotracheal stenosis. Apropos of 12 cases].

The authors report a series of twelve benign laryngotracheal strictures. In almost every case, these lesions were secondary to tracheal intubation and consisted of extensive, circumferential and almost complete stenosis. All were treated surgically. The authors obtained enlargement of the airway be means of an interposed cartilaginous graft and an intraluminal prosthesis which was left in place. In nine cases, this procedure was combined with posterior cricotomy. One eight month old infant died during the postoperative period. Ten patients had an uneventful postoperative course with a satisfactory anatomical and functional result.

[Inoperable cancer of the esophagus: preliminary results of combined chemotherapy (5-fluorouracil-cisplatin) and radiotherapy].

The aim of this study was to appreciate the tolerance and efficacy of a new nonoperative therapy for inoperable esophageal squamous cell carcinoma based on chemotherapy (5FU-cisplatinum) and concomitant splitcourse radiation therapy. Twenty five symptomatic patients (24 males, 1 female, mean age: 59 yrs, range: 41-72 yrs) were included. Five had 2 esophageal carcinoma, 5 an associated upper respiratory tract tumor and 2, relapse after surgery. Nine patients had a tumor limited to the esophagus (stage I or II) but were considered at high surgical risk. Sixteen had stage III disease with mediastinal involvement in 13 cases, nodal involvement in 4 and distant metastasis in 7. Treatment consisted of 2 cycles of chemotherapy with 5-FU (1 g/m2/24 h by continuous infusion for 5 days, D1-D5 and D29-D33) and cisplatinum (70 mg/m2 IV bolus on D2 and D30). Radiation therapy was concomitant in 2 courses delivering 20 grays in 5 days (D1-D5 and D29-D33). On the first day of the treatment, peroral endoscopic dilation or Nd-YAG laser therapy was applied. At the end of treatment all the patients could eat. Histoendoscopic control was performed 8 weeks after the beginning of therapy. Seventeen of the 24 patients had a complete response with negative biopsies. Of the 7 patients with metastatic disease, only 4 were evaluable for response to chemotherapy: one with hepatic metastasis had a complete response for 12 months, 2 had stable disease and one progressive disease.(ABSTRACT TRUNCATED AT 250 WORDS)

[Chemoprevention with intravenous doxycycline in 40 cases of colonic esophagoplasty].

Doxycycline was used to prevent infection in 40 patients undergoing oesophageal surgery (for carcinoma in 35 and for benign lesions in 5). Treatment began with induction of anaesthesia and continued in doses of at least 200 mg/day for a mean period of 10 days. Concentrations of the antibiotic were measured in the serum and colonic tissue of 20 patients, 2 hours on average after the first injection. Mean serum and tissue levels were 4.1 +/- 0.8 mcg.ml-1 and 2.9 +/- mcg.ml-1 respectively, with a tissue to serum ratio of 0.7. This ratio remained practically unchanged between the first and fourth hours post-injection. Doxycycline was successful in preventing post-operative infection in 75% of the cases. No infection due to anaerobic organisms was observed.

[Azygography in pre-operative investigation of cancer of the esophagus : a report on 24 cases (author's transl)].

The value of azygography for detecting extension of cancer of the middle third of the esophagus was assessed in 24 patients. The examination was conducted using the retrograde approach, and results were compared with those obtained by the esophagogram and on tracheobronchial fibroscopy. Compression of the azygos vein is a good indicator of the size of the tumor, which can also be evaluated from esophageal transit examinations. The vein can be invaded or even thrombosed due to severe regional spread but this does not mean that excision of the tumor is impossible. The results of azygography alone, therefore, are not a valid reason for contra-indicating esophagectomy. In case of doubt, tracheobronchial fibroscopy appears to be more suitable for deciding whether the tumor is operable, but azygography can assist in making this decision.

[Surgery for carcinoma of the esophagus. Methods and techniques].

Given the poor prognosis in carcinoma of the oesophagus, and with the aid of advances in anaesthesia and postoperative care, surgery has progressively evolved towards wider excision and a reduction in the number of operative stages. Partial oesophagectomy, with gastrolysis and gastro-oesophageal anastomosis, via a left thoracotomy, is favoured by large number of authors. However, it involves a certain number of disadvantages: by definition a limited excision, unsuitable for carcinomas in the cervical region and a marked risk of postoperative gastro-oesophageal reflux. Total oesophagectomy offers a hope of better results from an oncological standpoint, the more so since excision may be extended superiorly (laryngectomy) or inferiorly (total gastrectomy with lymph node excision). Continuity is re-established using a colonic transplant. The operation may be performed in two stages, though a single stage procedure with two teams would appear to be preferable, overall mortality and morbidity being reduced. Finally, colonic oesophagoplasty may be used alone, as a simply palliative measure, without associated tumour excision. By short-circuiting the oesophageal stenosis, it permits continued alimentation per os and the patient's period of survival is more comfortable.
