The use of flexible spiral drains after non-cardiac thoracic surgery. A clinical study.

OBJECTIVE: After an observational study on 50 patients determined the efficacy and safety of a small calibre (19F), flexible, fluted spiral drains with round cross-section after non-cardiac thoracic surgery we undertook a prospective study to compare these drains to standard chest drains also in terms of pain using a Visual Analog Score. METHODS: One hundred consecutive patients who had to undergo non-cardiac chest surgery either by thoracotomy or by VATS were randomly assigned to receive small calibre drains with round cross-section (group A) or the standard chest drains (group B) to drain the pleural space. Drains were connected to a unitized chest drainage system. Pain was assessed using a Visual Analog Scale (VAS) 0-100. RESULTS: The amount of fluid evacuated daily in patients who received the spiral drains was as much as 1150 ml, that of patients who received standard drains was as much as 950 ml. In no case did spiral drains have to be replaced with standard tubes. In group A first drain was removed after a mean of 3.4 days and the second after a mean of 5.9 days; in group B after a mean of 4.1 and 6.1 days, respectively. Patients were discharged after a mean of 8.5 days in group A (SD 4.04) and 8.1 days in group B (SD 4.76). There were no drains-related complications in both groups. The drains-related pain for the patient was significantly less for patients with spiral drains compared to standard drains at rest, during cough induced by respiratory therapists and at the time of removal. CONCLUSIONS: Spiral drains proved to be at least as safe and effective as conventional tubes after lung surgery; they allowed for evacuation of large amounts of blood/fluid as well as air, and were associated with minimal discomfort.

Lung resection for bronchogenic carcinoma after pneumonectomy: a safe and worthwhile procedure.

OBJECTIVES: Patients treated surgically for lung cancer can develop either a metachronous cancer or a recurrence. The appearance of a new cancer on the remaining lung after a pneumonectomy poses unique treatment problems, and surgery is often considered contraindicated. We report on the outcome of resections for lung cancer after pneumonectomy performed for lung cancer. METHODS: We reviewed the records of patients who underwent a resection of bronchogenic carcinoma on the remaining lung from 1990 to 2002. RESULTS: There were 14 patients (13 males and 1 female) with a median age of 64 years (range 51-74). Median preoperative Fev1 was 1.45 (range 1.35-2.23), corresponding to 59% of predicted Fev1 (range 46-80%). Resection was performed between 11 and 264 months after pneumonectomy (median 35.5). The resections performed were: one wedge resection in 11 patients, two wedge resections in two patients and two segmentectomies in two other patients; one patient underwent a third resection. Diagnosis was metachronous cancer in 12 patients and metastasis in two patients. Complications occurred in three patients (21%), while operative mortality was nil. Mean hospital stay was 10.5 days (6-25). Two patients received chemotherapy (one after local recurrence, one after the third resection). Overall 1, 3 and 5 year survivals were 57, 46 and 30%, respectively (median 21 months). For patients with a metachronous cancer they were 69, 55 and 37% (median 57 months), respectively, while neither patient with a metastatic tumor survived 1 year (P=0.03). CONCLUSIONS: Limited lung resection on a single lung is a safe procedure associated with acceptable morbidity and mortality rates. In patients with a metachronous lung cancer, long-term survival with a good quality of life can be obtained with limited resection on the residual lung.

Sleeve lobectomy for non-small cell lung cancer and carcinoids: results in 160 cases.

OBJECTIVE: To assess operative mortality (OM), morbidity and long-term results of sleeve lobectomies performed for non-small cell lung cancer (NSCLC) and carcinoids during a 35-year period. METHODS: A retrospective review of patients who underwent a sleeve lobectomy for NSCLC and carcinoids was undertaken, univariate and multivariate analyses of factors influencing early mortality in NSCLC were performed and for this purpose the series was split into an early and a contemporary phase, the Kaplan-Meier method was used to calculate the cumulative survival rate, and statistical significance was calculated with the log-rank test. Causes of death were evaluated in relation to the stage of the disease. RESULTS: OM for NSCLC was 14.6% in the early phase and 6% in the contemporary one; late stenosis occurred in 7.7% of NSCLC patients in the early phase and in 2% in the contemporary one. No OM or late stenosis occurred in carcinoid patients. Three, 5 and 10-year survival rates excluding carcinoids were 77, 62 and 31% for stage I(A-B), 45, 34 and 27% for stage II(A-B), 33, 22 and 0% for stage III(A-B). The 10-year survival rate for carcinoids was 100%. There was no significant difference in long-term survival between stages II and III, while the difference between stage I and stages II and III was significant (P<0.001). When survival was analyzed in relation to nodal status, 3, 5 and 10-year survival rates were 71, 57 and 33% for N0 disease, 42, 33 and 22% for N1 disease, and 34 and 19% with the last observation at 82 months of 19% for N2 disease; there was no significant difference in survival between N1 and N2 disease. A second primary lung cancer occurred in six patients (3.7%) who underwent resection. Late mortality was not related to cancer in most stage I patients while in stages II and III patients it was related to local and distant recurrences. CONCLUSIONS: Sleeve lobectomy is a valid alternative to pneumonectomy: careful patient selection and surgical technique make it possible to achieve a mortality rate comparable to or lower than that for pneumonectomy along with a better quality of life. In addition, it allows further lung resection, if necessary.

Completion pneumonectomy for non-small cell lung cancer: experience with 59 cases.

OBJECTIVE: The objective of this study was to assess the results of completion pneumonectomy performed for non-small cell lung cancer, classified as second primary or recurrence/metastasis. METHODS: From 1982 to 2000, 59 patients underwent completion pneumonectomy for lung cancer, classified second primary or recurrence/metastasis according to a modified form of Martini's criteria, after a mean interval from first resection of 60 months for second primary lung cancers and 19 months for recurrences/metastases. RESULTS: Operative mortality was 3.4% and complications occurred in 30% of patients. Five-year survival rate for completely resected patients was 25% (median 20 months). No significant difference in long-term survival was detected between second primary and recurrent tumors; survival was not adversely affected by a resection interval of less than 2 years or less than 12 months. CONCLUSIONS: Completion pneumonectomy for non-small cell lung cancer is a safe surgical procedure in experienced hands; long-term survival is acceptable and the best results are obtained for stage I lung cancer. Distinction between second primary lung cancer and recurrence failed to demonstrate a prognostic value.

Chemotherapy with an every-2-week regimen of gemcitabine and paclitaxel in patients with transitional cell carcinoma who have received prior cisplatin-based therapy.

BACKGROUND: An every-2-week regimen of gemcitabine and paclitaxel was adapted for patients with advanced transitional cell carcinoma (TCC) who had received prior cisplatin-based chemotherapy. METHODS: Forty-one patients with advanced or metastatic TCC who had received prior cisplatin-based systemic chemotherapy were treated with an outpatient regimen of gemcitabine 2500-3000 mg/m(2) and paclitaxel 150 mg/m(2) every 2 weeks. RESULTS: Forty of 41 patients had measurable disease. Response was observed in 24 patients (60%; 95% confidence interval [CI], 45-75%). Eleven (28%) achieved complete response, and 13 (33%) obtained partial response. Twenty of 25 patients (80%; 95% CI, 64-96%) who had been previously treated in the neoadjuvant or adjuvant setting responded versus 4 of 15 (27%; 95% CI, 5-49%) in patients who received prior methotrexate, vinblastine, doxorubicin, cisplatin (M-VAC) for metastatic disease. The median duration of survival for patients given gemcitabine and paclitaxel after failing neoadjuvant or adjuvant M-VAC was 12 months (range, 2-43+), as compared with only 8 months (range, 2-28) for patients who had been treated after failure of prior therapy for metastatic disease. For all patients, the median duration of response was 6.4 months (range, 2-43.3+ months), and the median survival was 14.4 months (range, 2-43+). Thirteen patients (32%) developed World Health Organization Grade 3-4 neutropenia, with febrile neutropenia in 3 (7%) patients. Granulocyte colony-stimulating factor was given to 10 (24%) patients. There was no Grade 3-4 anemia or thrombocytopenia. CONCLUSIONS: The combination of gemcitabine and taxol in previously treated patients with recurrent TCC is highly effective and produces objective durable responses. This every-2-week schedule is a well tolerated outpatient regimen with minimal toxicity.

Neo-adjuvant chemotherapy in invasive bladder cancer.

In patients with locally advanced muscle-invasive bladder cancer, neo-adjuvant chemotherapy was designed to treat micrometastatic disease present in up to 50% of patients at the time of diagnosis. Early chemotherapy has been combined with local therapy based on the reasoning that treatment of small volume disease would result in a better outcome. Another reason for giving neo-adjuvant chemotherapy is in an attempt to save the bladder. In selected patients, bladder preservation can be achieved with the use of chemotherapy plus radiotherapy, partial cystectomy, or transurethral resection of the bladder (TURB). Neo-adjuvant chemotherapy and bladder preservation remain controversial topics, as radical cystectomy is still considered to be the gold standard of treatment for muscle-invasive bladder cancer. The true success of bladder-preserving treatment by chemotherapy with or without RT will require validation in prospective randomized trials.

A phase II study of induction chemotherapy with gemcitabine (G) and cisplatin (P) in locally advanced non-small cell lung cancer: interim analysis.

BACKGROUND: Gemcitabine-cisplatin (GP) combination is one of the most active and well tolerated regimens in advanced non-small cell lung cancer (NSCLC). The aim of this study is to evaluate the activity and toxicity of the GP regimen as a 21-day schedule in patients (pts) with stage IIIAN2-IIIB NSCLC. PATIENTS AND METHODS: From October 1997 to July 2000, 47 pts entered the study: 43 were eligible (40 men and three women); median age was 61 years (range 45-73); ECOG PS 0-1; histology was squamous (20 pts), adenocarcinoma (12 pts), large cell (five pts), and undifferentiated (six pts); stage was IIIAN2 (14 pts, 32.56%), and IIIB (29 pts, 67.44%). Malignant pleural effusion or superior vena cava syndrome was criteria of exclusion. Induction treatment consisted of three cycles of GP (G 1250 mg/m(2) i.v. on days 1 and 8, and P 100 mg/m(2) on day 8 every 3 weeks). Responding and stable pts underwent surgery (S) and/or radiotherapy (RT). RESULTS: Following a minimum of two cycles, 39 pts were evaluable for response and 42 for toxicity. Two pts had complete responses (CR; 5.2%), 24 had partial response (PR; 61.5%), eight had stable disease (SD; 20.5%), and five had progressive disease (PRO; 12.8%). WHO grades 3 and 4 anaemia, neutropenia and thrombocytopenia were observed in two, four and two pts, respectively; non-haematological toxicity was moderate. After induction, stable and responding pts received either RT (18 pts) or S+RT (13 pts). Among the 16 resected pts, a radical complete resection was possible in 13 cases (81.3%), whereas tumour down-staging was observed in nine pts (56.2%). CONCLUSION: GP, as a 3-week neoadjuvant schedule, appears a safe and active regimen.

Differences in gene expression in muscle-invasive bladder cancer: a comparison of Italian and American patients.

OBJECTIVE: To seek differences in gene expression in the primary muscle-invasive bladder cancers of two cohorts of patients having different survival rates. An Italian group treated by transurethral resection of the bladder tumor (TURBT) and neo-adjuvant chemotherapy using methotrexate, vinblastine, adriamycin and cisplatin (M-VAC) followed by TURBT, partial cystectomy or radical cystectomy (75% 3-year survival) was compared to an American cohort treated by radical cystectomy (51% 3-year survival). METHODS: Immunohistochemistry was used to examine the protein expression levels of three genes that act at the G1/S cell cycle checkpoint, p53, p21/waf-1/cip1 (a downstream effector gene in the p53 pathway) and Rb, plus a major inhibitor of apoptosis, Bcl-2. RESULTS: For the bladder cancers of the Italian patient cohort, there was a significantly higher rate of p53 immunopositivity (93 vs. 63%, p = 0.002) and a significantly lower rate of Rb loss (25 vs. 54%, p = 0.009). In bivariate analysis, 72% of Italian tumors were immunopositive for both p53 and p21 (p53+/p21+) vs. 49% for the American tumors. The subset of Italian patients with p53+/p21+ tumors were more frequently disease-free (stage pT0) following chemotherapy and were less likely to fail therapy than those with p53+/p21- tumors (p = 0.0357). Loss of Rb staining was associated with a decreased 5-year survival in the Italian, but not in the American patients. CONCLUSIONS: (1) Significant differences in the expression of the p53, p21 and Rb genes were found between the 2 groups of patients. (2) Italian patients with p53+/p21+ tumors had significantly lower recurrence rates after TURBT and chemotherapy than those having p53+/p21- tumors. (3) Absence of p21 immunopositivity in the Italian tumors may identify alterations in the p53 pathway that predict poor outcome.

Rupture of spinal dermoid tumors with spread of fatty droplets in the cerebrospinal fluid pathways.

Cranial and spinal MRI was carried out at 0.5 or 1.5 T in five patients with spinal dermoid tumours. Free fatty material was appreciated within the normally communicating cerebrospinal fluid pathways in all five cases and in one case fat droplets were also observed within a dilated central canal of the spinal cord. While dissemination of lipid within the subarachnoid space and ventricles is easily understandable, the presence of lipid droplets within the central canal is more difficult to explain, since the central canal is only potential in the adult. When a dermoid tumor is suspected, we recommend MRI of the entire central nervous system, to detect possible leakage of fat from rupture of a cystic portion of the tumour.

Blake's pouch cyst: an entity within the Dandy-Walker continuum.

Abnormal cerebrospinal fluid (CSF) collections within the posterior fossa are defined by the Dandy-Walker complex (DWC) and by arachnoid cysts (AC). The DWC includes the Dandy-Walker malformation (DWM), the Dandy-Walker variant (DWV) and the mega-cisterna magna (MCM). In addition, Tortori-Donati et al. added persistent Blake's pouch cyst (BPC) as an independent entity within the DWC. BPC represents a posterior ballooning of the superior medullary velum into the cisterna magna. All of these malformations are overlapping developmental anomalies characterized by varying degrees of malformation of the medullary vela, the cerebellar vermis and hemispheres, the fourth ventricle choroid plexus, the posterior fossa subarachnoid cisterns and the enveloping meningeal structures. We present two cases of persistent BPC detected in two adult women without history of gestational or subsequent growth problems. They underwent neuroradiological investigation because of headache and because of recurrent episodes of loss of consciousness, respectively. The MRI findings included tetraventricular hydrocephalus, wide communication of the fourth ventricle and the cystic posterior fossa (i.e. BPC), inferior posterior fossa mass effect with or without hypoplasia of both the cerebellar vermis and the medial aspects of the cerebellar hemispheres, and absence of communication between fourth ventricle and the basal subarachnoid space in the midline posteriorly. Persistent BPC is defined by a failure of embryonic assimilation of the area membranacea anterior within the tela choroidea associated with imperforation of the foramen of Magendie. Typically this condition becomes symptomatic early in life. In the current cases the normal function of the laterally positioned foramina of Luschka probably helped to maintain some CSF flow between intraventricular and subarachnoid spaces, with the establishment of a precarious equilibrium characterized by a compensatory enlargement of the cerebral ventricular system (i.e. hydrocephalus).

MRI of radiation myelitis: a report of a case treated with hyperbaric oxygen.

Radiation therapy is commonly applied as a primary or adjuvant therapy for malignancies. One of the major complications following radiation therapy is the necrosis of the otherwise normal surrounding soft tissues and/or bone. Post-radiation myelopathy rarely occurs when the spinal cord is included within the radiation field, in cases of high total radiation doses or for high radiation doses per fractionation. Up until the present, no tolerance dose for the spinal cord has accurately been defined and no treatment has proved satisfactory. Hyperbaric oxygen therapy is already currently used as adjuvant treatment for osteoradionecrosis and for radionecrosis of soft tissues with satisfactory results, whereas results for the treatment of post-attinic myelitis were contradictory. The aim of our report is to describe a case of radiation myelitis with a progressive improvement in the clinicoradiologic picture following hyperbaric oxygen treatment.

Early hilar lung cancer--clinical aspects and long term survival. Identification of a subgroup of stage IA patients with more favorable prognosis.

Twenty-nine patients out of 2018 operated on for a non-small-cell lung cancer from 1987 to February 1998 met the criteria proposed by the Japan Lung Cancer Society (JLCS) for the definition of early hilar lung cancer (EHLC). Twenty-six patients were symptomatic and 20 had a radiologically visible lesion. All cancers were located and diagnosed by bronchoscopy and all patients were resected. At histology, all tumors were squamous in nature. The five-year cumulative survival rate was 96%--a second primary lung cancer (2nd Pr.) developed in 4 patients (13.8%). The definition of EHLC proposed by the JLCS allows the selection of a subgroup of stage I patients with a very good prognosis. Nevertheless, a close follow-up is mandatory because more than 10% of these patients develop a 2nd Pr.

Lung resection on single residual lung after pneumonectomy for bronchogenic carcinoma.

Seven patients who had undergone a pneumonectomy for lung cancer developed a second tumor in the remaining lung after a mean time of 28.5 months and underwent a further resection. Preoperative evaluation was based on standard functional tests and on the "stair climbing test". Three patients were operated on using an extracorporeal oxygenator to work on a collapsed lung, three using standard anesthesiologic techniques, and one using high-frequency jet ventilation. There was no operative mortality. Complications occurred in two patients, requiring a temporary tracheostomy in one case. No patient required home oxygen supplementation. Four patients died of metastatic disease after 4, 8, 10, and 12 months, while two patients are alive and free of disease after 83 and 9 months, one is alive and free of symptoms but with a local recurrence after 29 months. Lung resection for bronchogenic carcinoma on a single lung can be safely performed provided that careful clinical judgment is used; long-term survival can be achieved with the resection of the new tumor.

Isotonic smooth muscle response in human bronchi exposed in vitro to nitrogen dioxide.

Exposure to nitrogen dioxide (NO2), a common oxidant airborne pollutant, has been shown to cause reversible effects on lung function and airway responsiveness, in addition to airways inflammation. However, there have been conflicting reports concerning NO2-induced airway hyperresponsiveness. In the present study, we investigated the isotonic smooth muscle response in isolated human bronchi previously exposed in vitro to NO2. Bronchial segments were obtained from 12 patients who had undergone thoracotomy for lung cancer. Bronchial segments from each patient were exposed to air and to 2.5 parts per million (ppm) NO2 for 4 h. The contractile response of bronchial rings to acetylcholine, neurokinin A (NKA), and substance P was then studied under isotonic conditions. The response to NKA was also studied in rings, with or without epithelium, exposed either to air or 7 ppm NO2. No NO2-induced alteration of the bronchial smooth muscle isotonic response was found under any of the experimental conditions. We conclude that in vitro exposure to up to 7 ppm nitrogen dioxide does not cause alterations of the human bronchial smooth muscle shortening capacity.

[Indications for and results of video-assisted thoracic surgery].

Between January 1991 and February 1996, and February 1996, 222 videothoracoscopic operations were conducted in 215 patients. Indications for video-assisted thoracic surgery (Vats) have included management of pneumothorax, (91), pleural effusion (59), lung nodules (41), mediastinal biopsy (8), need for lung biopsy (10), small endothoracic masses (6), haemothorax (4), gangliectomy in Raynaud syndrome (1), the removal of jugular vein catheter (1), and middle lobectomy for A-V fistula (1). Fifteen procedures were converted to thoracotomy; nine conversions were made for more extensive resection after a diagnosis of primary lung malignancy. Other reasons for conversion were adhesions (6). There was one complication (haemothorax). There were no intraoperative deaths. Mean operative time was 60 min. (median line); the median chest tube duration was three days and hospital stay five days. The video-assisted thoracic surgery procedures were safe, and for patients the advantages included less pain and earlier post-operative mobilization.

The effects of toluene diisocyanate and of capsaicin on human bronchial smooth muscle in vitro.

Toluene diisocyanate contracts guinea-pig bronchial smooth muscle through a mechanism involving capsaicin-sensitive sensory nerves. In the present study, we investigated the effects of toluene diisocyanate, capsaicin and tachykinins on isolated human bronchi. In 44 rings, toluene diisocyanate (0.3 mM) produced a relaxation which averaged 16.9 +/- 1.1%, in ten rings it produced a shortening that was 15.1 +/- 3.3% and in ten preparations it gave no response. A second administration of toluene diisocyanate (0.3 mM) always produced a relaxation (n = 13, 18.1 +/- 3.9%). Capsaicin (0.03 mM) produced shortening in 15 (35 +/- 6.6%) and relaxation in 11 preparations (41 +/- 6.8%), whereas a second administration caused shortening in nine (25.1 +/- 6.1%) and relaxation in 16 rings (36.4 +/- 4.9%). When toluene diisocyanate was given after two consecutive capsaicin administrations, we observed shortening in two rings (10.0 +/- 3.6%), relaxation in ten rings (15.9 +/- 3.6%), and no response in four preparations. To test the role of NK1 and NK2 receptors in these conflicting responses, we performed concentration-response curves to different tachykinins. Substance P, neurokinin A and neurokinin A-(4-10), a specific NK2 receptor agonist, gave a concentration-dependent shortening, with neurokinin A being the most effective and neurokinin A-(4-10) the least. The specific NK1 receptor agonist, [Sar9, Met(O2)11]substance P, produced both shortening and relaxation. We conclude that toluene diisocyanate and capsaicin may produce both shortening and relaxation in isolated human bronchi through NK1 receptors.
