[Surgical treatment for pulmonary metastases from colorectal cancer].

Blalock first reported pulmonary resection for metastatic colorectal cancer in 1944. Since then, surgical resection of pulmonary metastases has been generally accepted as a standard therapeutic procedure in properly selected cases. Recently, the criteria of eligibility have been progressively expanded according to the development of radiological diagnosis using helical computed tomography (CT), widespread of minimum invasive video-assisted thoracic surgery. In this review summarized the surgical treatment of pulmonary metastases from colorectal cancer based on the recent literatures. Major areas of controversy remain with respect to the following aspects: prognostic factors (i.e., number of metastases, size of tumor, disease free interval, preoperative serum carcinoembryonic antigen level), procedure of operation (i.e., role of video-assisted thoracic surgery, lymphonode dissection), indication of surgical treatment on metastases both lung and liver, role of repeat thoracotomy for recurrence. For all above-mentioned points it appeared reasonable to try to the cooperative multicentric clinical prospective study.

[Cisplatin, 5-FU and preoperative radiotherapy in esophageal epidermoid cancer. Multicenter phase II FFCD 8804 study].

OBJECTIVES: The aim of this study was to analyze the efficacy and tolerance of preoperative radiochemotherapy in esophageal squamous cell carcinoma. Patterns of recurrence and prognostic factors were also studied. PATIENTS AND METHODS: This multicentric phase II trial included patients deemed operable. Preoperative treatment associated 5-FU 800 mg/m2/d by continuous infusion, cisplatin 20 mg/m2/d and radiotherapy 3 Gy/d D 1-5 and D 22-26. Resection was planned 50 to 60 days after the beginning of therapy. RESULTS: Seventeen centers accrued 96 patients, mean age 55.4 years. According to UICC 1978 classification: stage I 13%, stage II 53% and stage III 30%. Mean follow-up was 73 months. Pre-operative treatment was delivered at full dose in half of the patients. Ten percent of the patients did not receive the second cycle. Toxicity reached grade 3 in 23% and grade 4 in 7% of the patients. Two preoperative deaths occurred. Curative resection was performed in 82% of the patients. Operative mortality was 9%. tumors were sterilized on the operative specimen in 20% of the patients and microscopic remnants were observed in 13%. Preoperative clinical work-up overestimated histologic response in 10% of the cases underestimated it in 29%. After 2 years, a recurrence was observed in 56% of the patients: loco-regional in 30%, metastases in 19% and both in 7%. Median survival was 17 months and survival rates were 58% at 1 year and 25% at 5 years. Four prognostic factors influenced survival in multivariate analysis (Cox model): hematological toxicity grade 3 or 4, no complete response, circumferential extension > 2/3 and nodes visible on CT-scan. Factors positively influencing complete response were in multivariate analysis: a fungating tumor, weight loss < 8% and a full dose preoperative treatment. CONCLUSION: In this study, preoperative treatment associating 5-FU-cisplatin and radiotherapy allowed a high resectability rate, with one third of patients achieving complete or nearly complete histologic response. A randomized study is warranted to know whether this combined treatment is better than surgery alone.

Cost-minimisation analysis of pegylated liposomal doxorubicin hydrochloride versus topotecan in the treatment of patients with recurrent epithelial ovarian cancer in Spain.

The study consisted of a cost-minimisation analysis since the findings from a multicentre randomised phase III trial showed that pegylated liposomal doxorubicin hydrochloride was at least as efficacious as topotecan. An economic model from the Spanish hospitals perspective was constructed to compare the costs derived from the treatment using both drugs in patients with recurrent epithelial ovarian cancer who failed a first-line platinum-containing regimen. The cost evaluation included direct medical costs: drug, drug administration and costs of managing adverse events. Estimation of resources used in managing adverse events was made retrospectively through an expert panel. Results obtained per patient were: cost of drug and administration, 8647.70 euros for pegylated liposomal doxorubicin hydrochloride and 8519.94 euros for topotecan, while cost of managing adverse events was 967.02 euros in the pegylated liposomal doxorubicin hydrochloride arm and 3304.75 euros for topotecan. The total cost per patient was therefore estimated to be 9614.72 euros for pegylated liposomal doxorubicin hydrochloride and 11 824.69 euros for topotecan, showing that pegylated liposomal doxorubicin hydrochloride produces a cost saving of 2209.97 euros per patient in comparison to topotecan. Sensitivity analyses verified the robustness of the results. These findings suggest that pegylated liposomal doxorubicin hydrochloride is an efficient therapy and can be used as a cost-saving option for treatment of patients with recurrent epithelial ovarian cancer who have failed a first-line platinum-containing regimen.

Sialomucins at resection margin and likelihood of recurrence in colorectal carcinoma.

Oncogenic transformation of colonic epithelium is accompanied by changes in surface carbohydrate, notably an increased secretion of sialomucins at the expense of the normally predominant sulphomucins. In a multicentre prospective trial the correlation between the presence of sialomucins at the resection margin and the subsequent development of local recurrence was studied in 250 patients who had undergone "curative" resection for colorectal carcinoma with a mean follow up period of 14 months. Nineteen of 70 patients (27.1%) with a sialomucin predominant pattern at either resection margin developed local recurrence compared with 15 of 180 patients (8.3%) with a mixed or sulphomucin predominant pattern (p less than 0.01). Increased sialomucin staining at the resection margins was associated with reduced survival in these patients (p less than 0.01). At a mean of 14 months of follow up 153 patients (85%) were alive in the sulphomucin group and 53 patients (76%) were alive in the sialomucin group. Regression analysis predicted five year survivals of 32.8% and 18.9% for the sulphomucin and sialomucin groups respectively. Abnormal mucus production at the resection margin in patients treated for colorectal carcinoma appears to identify those with a higher risk of local recurrence and reduced survival.

[Recurrent ejection of aortic valve prostheses. Apropos of 22 case reports].

Twenty two cases of recurrent perivalvular leaks in aortic valve prostheses were reviewed in a multicentre cooperative study. From 1963 to 1978, 22 patients, mean age 39 years, underwent aortic valve replacement; 18 patients had aortic regurgitation, 6 due to infective endocarditis, and 4 patients had calcific aortic stenosis. Eight Starr-Edwards, 6 Smeloff-Cutter, 2 Braunwald-Cutter, 3 Björk, 1 Lillehei-Kaster and 2 bioprostheses were inserted. All 22 patients had to be reoperated for perivalvular leaks due to active or previous infective endocarditis in 7 cases. The prostheses implanted (3 reinsertions, 19 valve replacements) were 10 Starr-Edwards, 4 Smeloff-Cutter, 5 Björk, 1 Lillehei-Kaster, 1 Magovern and 1 bioprosthesis. All 22 patients had further perivalvular leaks, 6 caused by infective endocarditis, and 15 patients underwent a third operation. The prostheses implanted this time (2 reinsertions, 13 valve replacements) were 4 Starr-Edwards, 3 Smeloff-Cutter, 7 Björk and 1 bioprosthesis. Four patients had a third perivalvular leak, and 2 patients a fourth perivalvular leak. The first and second episodes of perivalvular leak were detected early in over half the cases. They were associated with cardiac failure, angina and hemolysis in 20 to 45% of cases. The average period between the first and second operations, and the 2nd and 3rd operations were 15 months and 9 months respectively. Overall, 11 patients died (50%), 4 due to cardiac failure and 3 of sudden death; 3 patients have been lost to follow-up (14%), and there are 8 survivors (36%) with a mean follow-up period of 5 years. However, the mortality rate when the cause of perivalvular leak was infective, was 82%, and only 18% when the cause was mechanical. The factors which favour recurrent perivalvular leaks are infection (30% of cases) and technical difficulties related to the poor quality of the aortic ring (calcification, dystrophy or dilatation). The prevention of this complication depends on careful peroperative technique, the use of certain surgical bypass techniques, a constant battle against infection, and regular examination of operated patients.

[Recurrent cerebrovascular insult--manifestation of POEMS syndrome?].

The POEMS syndrome is a multisystem disorder characterised by polyneuropathy, organomegaly endocrinopathy, plasma cell dyscrasia and skin changes. Along with many further manifestations this rare syndrome may also include macroangiopathy and acute vascular obliteration. In the literature such vascular problems have received only little attention and most case reports refer to involvement of the coronary and lower limb arteries. To our knowledge, the association with recurrent strokes has not been described. We report on a 59-year-old male with a complete form of POEMS syndrome associated with multicentric Castleman's disease. Despite absence of vascular risk factors, myocardial infarctions and ischemic necroses of toes occurred, and recurrent ischemic strokes appeared during oral anticoagulation. Recurrent strokes may therefore represent a further complication of the POEMS syndrome.

Calcium and fibre supplementation in prevention of colorectal adenoma recurrence: a randomised intervention trial. European Cancer Prevention Organisation Study Group.

BACKGROUND: Some epidemiological studies have suggested that high dietary intake of calcium and fibre reduces colorectal carcinogenesis. Available data are not sufficient to serve as a basis for firm dietary advice. We undertook a multicentre randomised trial to test the effect of diet supplementation with calcium and fibre on adenoma recurrence. METHODS: We randomly assigned 665 patients with a history of colorectal adenomas to three treatment groups, in a parallel design: calcium gluconolactate and carbonate (2 g elemental calcium daily), fibre (3.5 g ispaghula husk), or placebo. Participants had colonoscopy after 3 years of follow-up. The primary endpoint was adenoma recurrence. Analyses were by intention to treat. FINDINGS: 23 patients died, 15 were lost to follow-up, 45 refused repeat colonoscopy, and five developed severe contraindications to colonoscopy. Among the 552 participants who completed the follow-up examination, 94 stopped treatment early. At least one adenoma developed in 28 (15.9%) of 176 patients in the calcium group, 58 (29.3%) of 198 in the fibre group, and 36 (20.2%) of 178 in the placebo group. The adjusted odds ratio for recurrence was 0.66 (95% CI 0.38-1.17; p=0.16) for calcium treatment and 1.67 (1.01-2.76, p=0.042) for the fibre treatment. The odds ratio associated with the fibre treatment was significantly higher in participants with baseline dietary calcium intake above the median than in those with intake below the median (interaction test, p=0.028) INTERPRETATION: Supplementation with fibre as ispaghula husk may have adverse effects on colorectal adenoma recurrence, especially in patients with high dietary calcium intake. Calcium supplementation was associated with a modest but not significant reduction in the risk of adenoma recurrence.

Immediate versus deferred antiepileptic drug treatment for early epilepsy and single seizures: a randomised controlled trial.

BACKGROUND: The relative risks and benefits of starting or withholding antiepileptic drug treatment in patients with few or infrequent seizures are unclear. We sought to compare policies of immediate versus deferred treatment in such patients and to assess the effects of these policies on short-term recurrence and long-term outcomes. METHODS: We undertook an unmasked, multicentre, randomised study of immediate and deferred antiepileptic drug treatment in 1847 patients with single seizures and early epilepsy. Outcomes comprised time to first, second, and fifth seizures; time to 2-year remission; no seizures between years 1 and 3 and between years 3 and 5 after randomisation; and quality of life. Analysis was by intention to treat. FINDINGS: 404 patients invited to join the trial did not consent to randomisation; 722 were subsequently assigned immediate treatment with antiepileptic drugs and 721 were assigned deferred treatment. Immediate treatment increased time to first seizure (hazard ratio 1.4 [95% CI 1.2 to 1.7]), second seizure (1.3 [1.1 to 1.6]), and first tonic-clonic seizure (1.5 [1.2 to 1.8]). It also reduced the time to achieve 2-year remission of seizures (p=0.023). At 5-years follow-up, 76% of patients in the immediate treatment group and 77% of those in the deferred treatment group were seizure free between 3 and 5 years after randomisation (difference -0.2% [95% CI -5.8% to 5.5%]). The two policies did not differ with respect to quality of life outcomes or serious complications. INTERPRETATION: Immediate antiepileptic drug treatment reduces the occurrence of seizures in the next 1-2 years, but does not affect long-term remission in individuals with single or infrequent seizures.

Evaluation of different treatment modalities for vulvar intraepithelial neoplasia (VIN): CO(2) laser vaporization, photodynamic therapy, excision and vulvectomy.

OBJECTIVES: To evaluate various treatment modalities for vulvar intraepithelial neoplasia (VIN) in relation to possible risk factors for recurrence. METHODS: Retrospective review of 93 patients with VIN treated by CO(2) laser vaporization, photodynamic therapy with aminolevulinic acid (PDT), excision or vulvectomy. RESULTS: 40.4% of the 47 patients with laser vaporization, 48.1% of 27 patients with PDT, 42% of 12 patients with local excision and none of the 7 patients treated by vulvectomy experienced a relapse within a mean follow-up of 53.7 months. The risk for recurrence significantly increased with VIN grade (P = 0.02), multifocal VIN disease (P = 0.01), multicentric intraepithelial neoplasia (P = 0.05) and high-risk HPV infection (P < 0.001). In multivariate analysis, only HPV status remained significant (P = 0.012) and, if HPV testing is not available, multifocality (P = 0.03). The lowest rate of postoperative side effects was noted in patients after PDT. There was one (1%) case of progression to vulvar cancer. CONCLUSIONS: Vulva preserving treatment methods for VIN have high recurrence rates, especially in patients with HPV infection and multifocal disease. Therefore, careful long-term surveillance is mandatory.

Epithelial-myoepithelial carcinoma of the parotid gland. An unusual cause of ear canal stenosis.

Epithelial-myoepithelial carcinoma (EMC) accounts for approximately one per cent of salivary gland tumours. This tumour is gaining wider recognition following inclusion into the WHO histological classification of salivary gland tumours in 1990. Salivary gland tumours characteristically present with an enlarging mass. We describe an unusual presentation of a salivary gland tumour with stenosis of the external ear canal in the absence of a palpable mass. EMC usually arises from the salivary glands but isolated cases have been described arising primarily from the paranasal sinuses, trachea and lacrimal gland. The management of this tumour is still evolving with surgical excision being the main-stay of treatment. The efficacy of radiotherapy has not yet been established but high local recurrence rates despite apparently adequate excision and the possibility of a multicentric origin of the tumour may herald an increasing role for radiotherapy in the future. We stress the importance of awareness of adjacent structures when considering the cause of cartilaginous canal stenosis.

Subtotal maxillectomy for melanotic neuroectodermal tumor of infancy.

Melanotic neuroectodermal tumor of infancy is a rare pigmented neoplasm occurring in infants before 1 year of age. It is a rapidly growing tumor that most frequently affects the craniofacial skeleton. Although melanotic neuroectodermal tumor of infancy is benign in the vast majority of cases, inadequate excision, occasional multicentricity, and a small malignant potential result in a fairly high recurrence rate. On the basis of data obtained from the literature and our clinical experience, we advocate an aggressive surgical approach consisting of complete surgical excision when vital structures are not involved. Histopathologic confirmation of complete excision is mandatory to minimize the risk of recurrence and provide the patient with curative treatment and minimal morbidity.

Omeprazole versus famotidine in the short-term treatment of duodenal ulcer disease.

The efficacy and safety of omeprazole, in 241 patients with active recurrent duodenal ulcer from 21 Italian centres, was studied in a multicentre double-blind randomized trial comparing 20 mg omeprazole o.m. or 40 mg famotidine nocte with endoscopic examination, symptom recording, laboratory screening and gastrin assay. In a per protocol analysis, the duodenal ulcer healing rates for omeprazole and famotidine, documented by endoscopy, were 62% (68/109) and 33% (39/117) after 2 weeks of treatment (P less than 0.001), 92% (96/104) and 80% (86/108) cumulative after 4 weeks (P less than 0.05), and 99% (102/103) and 92% (96/104) after 6 weeks (P less than 0.05), respectively. The results of this trial demonstrate that 20 mg omeprazole o.m. is superior to 40 mg famotidine nocte in duodenal ulcer healing.

Breast cancer: do histopathology reports provide adequate information for patient care?

INTRODUCTION: Many studies have shown that certain pathologic features correlate with risk of recurrence, development of nodal and distant metastases, long term survival and multicentricity of breast carcinoma. Such information is useful in selection of appropriate therapy and prognostication. OBJECTIVE: To determine the proportion of histopathology reports of breast carcinoma that provide essential pathologic prognostic information. METHOD: All (110 mastectomy and 25 lumpectomy) cases of breast carcinoma reported during 79-month period from January 1992 were assessed for inclusion of tumour size, information on excision margins and 8 microscopic features. Mastectomy reports were evaluated for information on axillary lymph node status. RESULTS: 9.6% of reports assessed included all relevant features. All 110 mastectomy reports gave information on axillary lymph node status. Tumour size was included in 91.1% of reports. Excision margins were commented on in 36% of lumpectomy reports. Of the microscopic features assessed, tumour type was included in 98.5% and histologic grade in 66.7%. In formation on other features ranged from 28.1% for inflammatory infiltrate at the tumour-host interface to 69.1% for nipple invasion. CONCLUSION: Reporting on basic prognostic information falls short of the ideal. Provision of guidelines will help to ensure the inclusion of relevant histopathologic prognostic information.

Bilateral Warthin's tumors in a Chinese--literature review and case report.

Warthin's tumor is an unusual benign salivary gland tumor. It is predominantly found in Caucasians and is rare in non-Caucasians. The chief affected area of the tumor is the parotid gland. Of all salivary gland neoplasms, Warthin's tumor is the only lesion which is truly multicentric so it may have a second primary lesion, not a recurrence. The peak incidence is in the sixth decade of life. In sexual distribution, there is a male predominance but the incidence of female is progressively increasing. According to Lemelas's study, the increase in female incidence may relate to the increasing population of cigarette smoking of women. Bilateral parotid gland involvement is uncommon. The chief treatment of the tumor is surgical excision. The surgical methods include enucleation, superficial parotidectomy, total parotidectomy. It is very important to protect the facial nerves from injury during surgery. In this paper, we report a case of bilateral metachronous Warthin's tumors with cystic degeneration of parotid glands in a Chinese. Other than literature review and case report, four different methods to protect facial nerves from injury were briefly described.

[Diagnostic laparoscopy within the scope of appendicitis treatment. East German Working Group "Outcome Assessment and Quality Assurance in Surgery" of the CAQ of the German Society of Surgery].

The diagnostic laparoscopy represents a special technique with high impact for differential diagnosis especially in patients with chronic recurrent pain in the right lower abdomen. The East-German multicentric trial confirmed the actual trend of increasing importance of the laparoscopic method especially in patients with unclear abdominal findings. In case of surgical treatment because of chronic appendicitis in 61.7% (n = 370) of all these cases an laparoscopic procedure was preferred. Unclear abdominal findings were treated in 73.7% (n = 205) laparoscopically. In case of acute appendicitis in 72.2% (n = 2934) the open procedure was preferred. The diagnostic laparoscopy can avoid the overlook of findings requiring therapy. The consequent laparoscopic approach allows to achieve a decreased rate of non necessary laparotomies as well as non detected findings requiring surgery. The rate of gynaecological findings was 16.2% (n = 184) of all women who underwent diagnostic laparoscopy versus 6.4% who underwent open appendectomy (n = 116).

Influence of failure of primary wound healing on subsequent recurrence of pilonidal sinus. combined prospective study and randomised controlled trial.

OBJECTIVE: To find out whether failure of primary wound healing after excision and primary suture for chronic pilonidal sinus predicts recurrence. DESIGN: Follow-up of one prospective study and one subsequent randomised, multicentre study. SETTING: Three teaching hospitals in WesternNorway. SUBJECTS: A total of 197 consecutive patients operated on for chronic pilonidal sinus. INTERVENTIONS: Fifty two patients in the prospective group were given cloxacillin perioperatively. In the randomised study, 145 patients were randomised to have either a single preoperative dose of cefoxitin 2 g intravenously (n = 73) or no prophylaxis (n = 72). Patients were followed up for a median of 7 years. MAIN OUTCOME MEASURES: Recurrence of pilonidal sinus. RESULTS: In the prospective group there were 10 recurrences (19%). In the randomised study 6 patients (8%) who had been given antibiotic prophylaxis had a recurrence compared with 14 patients (19%) who had not been given prophylaxis (p = 0.09). In both groups, failure of primary normal healing was significantly associated with early recurrence (p = 0.0002). Neither the use of antibiotics nor sex had any significant influence on the incidence of recurrences. Most recurrences occurred within the first year. CONCLUSION: Wound complications significantly influenced the recurrence rate whereas antibiotics did not. Most recurrences were seen early.

[Risk factors for recurrence of vulvar intraepithelial neoplasia III (VIN III)].

OBJECTIVE: The incidence of vulvar intraepithelial neoplasia (VIN) has increased in the last decades. The therapy of VIN is the in toto resection. Still some patients develop VIN recurrence. The aim of this retrospective study is the identification of risk factors for VIN recurrence. MATERIAL AND METHODS: 68 Patients with VIN III has been examined in an univariate and multivariate analysis for the following parameters (follow-up: median 27 months): age, HPV, HIV, multicentricity, resection margins (1-4 mm, 5-9 mm, > or = 10 mm). RESULTS: In the univariate analysis positive HPV and HIV status correlated with VIN recurrence. Also resection margins < 5 mm showed a significant correlation with VIN recurrence. Multivariate analysis demonstrated that HPV, HIV and resection margins < 5 mm are independent risk factors. No statistically association was found for age and multicentricity. CONCLUSION: The aim of VIN therapy must be the total resection with a negative resection margin of > or = 5 mm. HPV- and/or HIV-positive patients have a significantly higher risk for VIN recurrence and need therefore an intensive follow up.
