[Oesophageal squamous cell carcinoma stade III. State of surgery after radiochemotherapy (RCT)].

Neoadjuvant chemoradiotherapy is the gold standard of the treatment of advanced oesophageal squamous cell carcinoma. The role of surgery after chemoradiotherapy is still debated. Feasibility of curative resection depends on dose of radiotherapy, morbimortality rates, and nutrition status at the end of the protocol especially for non-responders patients. Adding surgery to radiochemotherapy improves local tumour control but does not increase overall survival of patients with advanced oesophageal squamous cell carcinoma. According to the two randomised trials published on the subject, surgery is not recommended after chemoradiotherapy for responders. Recommendations of French National Thesaurus are: exclusive chemoradiotherapy as reference, esophagectomy for residual tumour as alternative for operable patients. Surgery may be proposed for selected non-responders patients and some complete pathology response in expert center.

A comparative longitudinal quality of life study using the Spitzer quality of life index in a randomized multicenter phase III trial (FFCD 9102): chemoradiation followed by surgery compared with chemoradiation alone in locally advanced squamous resectable thoracic esophageal cancer.

BACKGROUND: The aim of the study was to compare the longitudinal quality of life (QoL) between chemoradiation with or without surgery in patients with locally advanced squamous resectable esophageal cancer included in a randomized multicenter phase III trial (FFCD 9102). MATERIALS AND METHODS: All patients with locally advanced resectable (T3-4 N0-1 M0) epidermoid or glandular esophageal cancer (n = 451) received induction chemoradiation. Responders (n = 259) were randomized between surgery (arm A) and continuation of chemoradiation (arm B). The Spitzer QoL Index was scored (0-10) at inclusion and at each follow-up, every 3 months during 2 years. QoL at baseline and longitudinal changes were respectively compared with univariate ANOVA and mixed-model analysis of variance for repeated measurements. The time interval between the follow-up was assessed and the same analyses were performed among survivors with 2 years of follow-up. RESULTS: The squamous histology was predominant in both arms. The mean QoL score decreased between baseline and the first follow-up and between the first and the second follow-ups. QoL scores at the first follow-up were comparatively worse in arm A than in arm B (7.52 versus 8.45, P < 0.01), whereas the longitudinal QoL study showed no difference between treatments (adjusted P = 0.26). Furthermore, the longitudinal QoL was not different (adjusted P = 0.23) among survivors with 2 years of follow-up. CONCLUSIONS: Among patients responding to induction chemoradiation, surgery and continuation of chemoradiation had the same impact on QoL in patients with locally advanced, resectable esophageal cancer although a significantly greater decrease in the Spitzer Index was observed in the postoperative period.

[Type I neurofibromatosis, pheochromocytoma and somatostatinoma of the ampulla. Literature review].

Gastrointestinal involvement in Von Recklinghausen's neurofibromatosis (autosomal dominant disease) is observed in 25% of patients and is frequently represented by duodenal carcinoids. We report a case of somatostatinoma of the ampulla in a 42-year-old female with neurofibromatosis and pheochromocytoma and show a literature review about the association of neurofibromatosis and somatostatinoma. This pathological association appears non hasardous and surgical ampullectomy offers a good alternative to pancreaticoduodenectomy in localised tumors treatment.

Impact of preoperative radiochemotherapy on postoperative course and survival in patients with locally advanced squamous cell oesophageal carcinoma.

BACKGROUND: The aim of this study was to determine the effect of neoadjuvant radiochemotherapy (RCT) on postoperative complications and survival after surgery for locally advanced oesophageal squamous cell carcinoma. METHODS: Postoperative course and survival were compared in 144 patients who had neoadjuvant RCT and 80 control patients who had surgery alone for locally advanced oesophageal squamous cell carcinoma (radiological stage T3, N0 or N1, M0). RESULTS: The two groups were comparable in terms of American Society of Anesthesiologists grade, age, sex, weight loss, tumour location, presence of lymph node metastasis and surgical approach. Postoperative mortality rates were 6.3 and 9 per cent (P=0.481), with morbidity rates of 40.3 and 41 percent (P=0.887) in the RCT and control group respectively. Complete resection (R0) rates were 74.3 and 48 percent respectively (P<0.001). Significant downstaging was observed in the RCT group (P<0.001), with 16.0 percent of patients having a complete pathological response. Median survival was 29 versus 15 months, and the 5-year survival rate 37 versus 17 percent (P=0.002) in RCT and control groups respectively. CONCLUSION: Neoadjuvant RCT significantly enhanced R0 resection and survival rates in patients with stage T3 oesophageal squamous cell carcinoma, with no increase in postoperative mortality and morbidity rates.

[Mesenteric panniculitis].

Mesenteric panniculitis also named retractile mesenterite is a rare tumor-like lesion that thickens and shortens the mesentery. It is characterized by the association of inflammation, necrosis or fibrosis involving the adipose tissue of the bowel mesentery. The pathophysiology of this disease remains unclear despite associations with inflammatory diseases or malignancies, especially lymphomas that have been described. When symptomatic, patients may present with abdominal pain, palpable abdominal mass or intestinal obstruction. The disease remains asymptomatic in 30 to 50% of cases. Abdominal CT plays an important role in suggesting the diagnosis and can be useful in distinguishing the several conditions that can mimic mesenteric panniculitis. Nevertheless, pathologic examination of surgical excisional biopsies or sometimes percutaneous biopsies remains necessary to confirm the diagnosis and exclude an underlying infection or malignancy. Medical treatment may consist of therapy with anti inflammatory or immunosuppressive agents and can be proposed in highly symptomatic diseases. Surgical treatment should be exclusively attempted when intestinal obstruction or ischemia occur. Most of the time, it consists in intestinal derivation or segmental resection because complete excision of the lesions is often not possible. Mesenteric panniculitis usually has an uneventful clinical course and resolves spontaneously in a variable delay.

Photodynamic therapy for early oesophageal cancer.

BACKGROUND: Photodynamic therapy is an endoscopic treatment of early cancers based on the photosensitisation of neoplasms following the administration of a photosensitiser prior to laser light-induced tissue destruction. AIM: To assess the results of photodynamic therapy using Photofrin(Axcan Pharma Inc., Quebec, Canada) in patients with an early oesophageal cancer. PATIENTS: Twenty-four patients with early oesophageal cancer presenting as a not well-demarcated irregular dyschromic area of mucosa and unsuitable for any other treatment underwent photodynamic therapy. RESULTS.: Seventy-five per cent were successfully treated; three of them recurred and two died from head and neck cancer. To date, 54% of patients are alive without recurrence; the average follow-up is 21 months. There were one oesophageal lethal perforation and six stenosis. Results of photodynamic therapy were limited in this series by three failures, three recurrences and three deaths from previous head and neck cancers. CONCLUSION: This study provides some promising data for photodynamic therapy of oesophageal carcinomas in selected patients. It also emphasises the need for a best delivery device of laser light.

[Cervical and upper-third thoracic oesophageal carcinoma: a single pathological entity?].

AIM OF THE STUDY: Cervical and upper-third thoracic oesophageal carcinomas are considered as a single pathological entity. The aim of this study was to compare postoperative and oncological results after surgical resection in these two locations. MATERIAL AND METHODS: Postoperative and oncological results were compared retrospectively in 155 patients who underwent surgery for carcinoma of the cervical (C group, n = 21) or upper-third thoracic (TS group, n = 134) oesophagus. RESULTS: The two groups were comparable regarding the pre-, peroperative and histological data. Postoperative mortality and morbidity rates in the C and TS groups were 4.8% and 10.4% (P= 0.413) and 57.1 and 50.7% (P= 0.585), respectively. R0 resection and recurrence rates were 61.9% and 73.1% (P= 0.289) and 50.0% and 51.1% (P= 0.941), respectively. Five-year survival rates were 0% and 35% in the overall population (P= 0.098) and 0 and 49% in the R0 population (P= 0.047), respectively. By multivariate analysis, cervical location of the tumour was found to be an independent factor of poor prognosis (relative risk= 3.1, 95% confidence interval= 1.3-7.8, P= 0.014). CONCLUSION: Prognosis after surgical resection of cervical oesophagus carcinoma is very poor. Surgery in this location should be proposed in case of chemoradiation failure.

[Radiotherapy and chemotherapy in the treatment of oesophageal carcinoma].

Surgery, chemotherapy and radiotherapy are the three major arms of treatment for cancer of the oesophagus, and combined modality therapy is required to treat advanced disease. Exclusive chemoradiotherapy is a feasible option for locoregionally advanced disease in responder patients. Elective surgery as a palliative procedure should not be regarded as a standard option in patients with metastatic or non-resectable oesophageal cancer. Surgery appears more and more as an adjuvant therapy in the curative treatment of oesophageal cancer, especially for advanced tumours.

Surgery alone in the curative treatment of localised oesophageal carcinoma.

AIM: To document the results of surgery alone in patients with localised oesophageal carcinoma. METHODS: Between January 1982 and 2002, 179 consecutive patients who underwent curative oesophagectomy for stage 0, I or II oesophageal carcinoma, without neo-adjuvant treatment, were analysed retrospectively. RESULTS: Postoperative mortality and morbidity rates were 2.8 and 30.7%, respectively. The overall actuarial survival rate at 5 years was 59%. No patients with more than four invaded lymph nodes survived 5 years. A lymph node ratio more than 0.2, more than four invaded lymph nodes and an advanced pTNM stage were predictors of poor prognosis. CONCLUSION: Long-term survival after surgery alone for localised oesophageal carcinoma can be achieved in some 2/3rds of patients. These results should be considered before designing neo-adjuvant therapeutic regimen or embarking into exclusive treatment alternate to oesophagectomy.

[Post-traumatic endocapsular blood effusion].

A rare complication after extracapsular surgery of the cataract, blood effusion is often a fortuitous discovery when a drop in visual acuity occurs. The subject reported herein is a 76-Year-old patient who presented an endocapsular blood effusion with no liquid level 1 Year after the extracapsular surgery of the cataract, discovered while examining a decrease in visual acuity. Questioning led to the discovery of eye trauma due to Nd: YAG laser posterior capsulotomy 3 Months before, which had progressed spontaneously and favorably for 2 Months, with a reduction of the effusion and better visual acuity. The bleeding seems to have come from a vascular injury due to a direct contusion, with blood possibly coming from the ciliary body, the iridocorneal angle, or the vitreous. The liquid effusion may have been caught at the back by the implant and enclosed in the area located between the capsular bag and the anterior hyaloid, without intravitreous diffusion. Most of reported cases in the literature discuss observations made on an intact posterior capsule, which appeared during or after close surgery. The treatment was simple supervision. Some Authors propose a Nd: YAG laser capsulotomy in case resorption is too slow.

Value of endoscopic ultrasonography as a predictor of long-term survival in oesophageal carcinoma.

BACKGROUND: : Endoscopic ultrasonography (EUS) is considered to be the best locoregional staging technique for cancer of the oesophagus. This study evaluated the relationship between preoperative EUS findings, completeness of surgical resection and survival. METHODS: : Between January 1995 and July 2002, 150 patients who underwent EUS for staging of tumours of the oesophagus were analysed prospectively. All underwent surgical resection with curative intent without neoadjuvant treatment. RESULTS: : Patient survival was significantly related to tumour (EUS T), node (EUS N) and Union Internacional Contra la Cancrum classification (EUS UICC) stage according to sonographic findings (P = 0.003, P = 0.009 and P = 0.004 respectively), and the presence of stenosis determined by EUS (P = 0.004). EUS T stage was a prognostic factor for survival (relative risk 1.7 (95 per cent confidence interval (c.i.) 1.1 to 3.0); P = 0.046). Complete surgical resection (R0) was also significantly related to EUS T, N and UICC classification (P < 0.001). EUS UICC stage was a factor predictive of R0 resection (relative risk 2.6 (95 per cent c.i. 1.4 to 4.8); P = 0.003). CONCLUSION: : R0 resection and survival of patients with tumours of the oesophagus were strongly related to endosonographic findings. These results support the proposal that EUS should be performed in all patients with oesophageal cancer, not only for staging patients before therapy but also to determine prognosis.

[Patients surviving 5 years after curative oesophagectomy for oesophageal cancer].

AIM OF THE STUDY: To analyse the clinical and pathological parameters of 5-year survival patients after curative oesophageal resection for cancer and to identify factors predictive of long-term survival. METHODS: The data of 370 patients who underwent oesophagectomy with curative intent from January 1982 for oesophageal squamous cell carcinoma (n = 320) or adenocarcinoma (n = 50) were reviewed. After excluding postoperative deaths (n = 20), these patients were surviving (S group, n = 113) or dead (NS group, n = 237) with a 60-month follow-up. Uni- and multivariate analysis allowed comparison between the two groups. RESULTS: Postoperative mortality and morbidity rates were 4.0% and 37.6%, respectively. Parameters related to 5-year survival were: absence of preoperative malnutrition or dysphagia, transhiatal resection, no reoperation, limited tumour, histological response to neoadjuvant treatment, absence of lymph node capsular invasion, number of invaded lymph nodes < or = 4, invaded lymph node ratio < or = 0.1, absence of tumour recurrence or metachronous primary cancer. On multivariate analysis, factors predictive of 5-year survival were: absence of preoperative dysphagia (P < 0.001), stage 0-I-IIA tumour (P<0.001) and absence of metachronous cancer (P = 0.016). CONCLUSION: Complete surgical resection allows 5-year survival. Factors predictive of long-term survival assessed in preoperative evaluation, dysphagia and tumour stage, should be useful to select patients for neoadjuvant treatment.

Extent of oesophageal resection for adenocarcinoma of the oesophagogastric junction.

AIMS: The optimal extent of oesophageal resection and surgical approach in patients treated for adenocarcinomas of the oesophagogastric junction (OGJ) are still uncertain. We report the correlations between resection margin involvement and outcome. METHODS: Patients with positive proximal resection margin (PPRM) and those with negative proximal resection margin (NPRM) were compared. RESULTS: Of 94 patients with macroscopically complete resection, eight were PPRM. There was no difference between the two groups in postoperative mortality or morbidity rates, in anastomotic leakage or in recurrence rates. The median survival in the PPRM group was 11.1 months compared with 36.3 months in the NPRM group (P=0.02). No infiltration was observed in patients whose proximal margin exceeded 7 cm. The extended transthoracic approach was the only prognostic factor for tumours type II (P=0.03, RR=1.4, 95% CI: 1.1-1.8). CONCLUSION: Histologic infiltration of oesophageal resection margin influences 5-year survival rate. In adenocarcinomas of the OGJ that can be treated curatively, a transection with a 8 cm oesophagectomy above the tumour in fresh specimen should be performed, and by thoracoabdominal approach for tumours type I and II.
