Initial institutional experience with thoracoscopic assisted esophagectomy.

We report our initial experience with thoracoscopic assisted esophagectomy (TAE) in patients with esophageal carcinoma. Clinical outcome measures are reported for 14 consecutive patients who underwent thoracoscopically assisted esophagectomy at our institution between January 2007 and June 2009. These outcomes were compared with 18 patients who underwent open esophagectomy (OE) during this time. All 14 patients were male, with a median age of 63. All had distal esophageal adenocarcinoma: stage I (7), II A (2), II B (3), and III (2). Surgical approaches included laparotomy combined with thoracoscopy and cervical (n=12), or intrathoracic anastomosis (n=2). Compared with an open approach, the thoracoscopic assisted esophagectomies were longer (median time 460 vs. 386 minutes), and they were associated with less blood loss (250 mL vs. 500 mL) and less respiratory complications (14.3% vs. 27.8%). In our TAE group more lymph nodes were removed (median number 12 in TAE vs. 10 in OE). The overall morbidity was similar in both groups (42.8% in TAE vs. 50% in OE group), but the in-hospital mortality was reduced with TAE (7.1% with TAE vs. 16.7% with OE). TAE is feasible with a low conversion rate, acceptable morbidity, and low mortality.

A phase I study of gefitinib with concurrent dose-escalated weekly docetaxel and conformal three-dimensional thoracic radiation followed by consolidative docetaxel and maintenance gefitinib for patients with stage III non-small cell lung cancer.

BACKGROUND: Concurrent radiation and chemotherapy is the standard of care for good performance status patients with stage III non-small cell lung cancer. Locoregional control remains a significant factor relating to poor outcome. Preclinical and early clinical data suggest that docetaxel and gefitinib have radiosensitizing activity. This study sought to define the maximum tolerated dose of weekly docetaxel that could be given with daily gefitinib and concurrent thoracic radiation therapy. PATIENTS AND MATERIALS: Patients with histologically confirmed, inoperable stage III non-small cell lung cancer and good performance status (Eastern Cooperative Oncology Group 0-1) were eligible for this study. Patients received three-dimensional conformal thoracic radiation to a dose of 70 Gy concurrently with oral gefitinib at a dose of 250 mg daily and intravenous, weekly docetaxel at escalating doses from 15 to 30 mg/m2 in cohorts of patients. Patients were given a 2-week rest period after the concurrent therapy, during which they received only gefitinib. After the 2-week rest period, patients received consolidation chemotherapy with docetaxel 75 mg/m2 given every 21 days for two cycles. Maintenance gefitinib was continued until disease progression or study completion. RESULTS: Sixteen patients were enrolled on the study between December 2003 and April 2007 with the following characteristics: median age, 64 years (range 43-79 years); M/F: 9/7; and performance status 0/1, 1/15. Dose-limiting pulmonary toxicity and esophagitis were encountered at a weekly docetaxel dose of 25 mg/m2, resulting in a maximum tolerated dose of 20 mg/m2/wk. Overall, grade 3/4 hematologic toxicity was observed in 27% of patients. Grade 3/4 esophageal and pulmonary toxicities were reported in 27% and 20% of patients, respectively. The overall response rate was 46%, and the median survival for all patients was 21 months. CONCLUSIONS: Concurrent thoracic radiation with weekly docetaxel and daily gefitinib is feasible but results in moderate toxicity. For further studies, the recommended weekly docetaxel dose for this chemoradiation regimen is 20 mg/m2.

Angiofollicular lymph node hyperplasia resembling a spinal nerve sheath tumor: a rare case of Castleman's disease.

BACKGROUND CONTEXT: Angiofollicular lymph node hyperplasia (Castleman's disease) is a lymphoproliferative disorder of unknown etiology. Although uncommon, the localized form of this disease can manifest in the central nervous system, typically as a meningeal-based intracranial lesion. Castleman's disease involving the spine is exceedingly rare. This represents only the second reported case of a patient with Castleman's disease whose presentation mimicked that of a spinal nerve sheath tumor. PURPOSE: We report a rare case of angiofollicular lymph node hyperplasia that mimicked a spinal nerve sheath tumor and was treated with gross total resection. STUDY DESIGN: Case report. PATIENT SAMPLE: A 31-year-old female with angiofollicular lymph node hyperplasia presenting with a paraspinal mass. OUTCOME MEASURES: The patient's outcome was based on clinical history, physical and radiographic examinations. METHODS: A 31-year-old woman with a mediastinal mass previously diagnosed as sarcoid via biopsy presented with the new onset of radicular pain and radiographic enlargement of her mass. Magnetic resonance imaging demonstrated a 4.3x5.7x6.0 cm homogenously enhancing soft-tissue lesion that emanated from and widened the T3/T4 neural foramen on the left. The differential diagnosis based on the location of the lesion and imaging characteristics included schwannoma, neurofibroma, paraganglioma, sarcoid, and lymphoma. Gross total resection was performed via thoracotomy. Histological examination identified angiofollicular lymph node hyperplasia (Castleman's disease) of the hyaline-vascular subtype. The patient did not receive adjuvant chemotherapy or radiation therapy. RESULTS: The patient had resolution of her symptoms without any clinical or radiographic evidence of recurrence at 1-year follow-up using magnetic resonance imaging with and without contrast. CONCLUSIONS: Castleman's disease is a rare pathologic entity that should be considered in the differential diagnosis of a patient with a paraspinal mass. Spine surgeons should be aware of this diagnosis as it has treatment and follow-up implications that differ from the neoplasms it can mimic. Complete surgical excision is an effective treatment for solitary lesions. Screening for concurrent and future malignancies in these patients is prudent.

Constrictive pericarditis after cardiac transplantation: a case report and literature review.

We present a patient who was found to have constrictive pericarditis 6 months after cardiac allograft transplantation. The many invasive and non-invasive diagnostic procedures that were undertaken are reviewed, as is the gross pathology seen during surgery. In addition, the entity of constriction in the transplant patient is placed in context by an examination of the previous literature.

Coronary artery bypass grafting with single cross-clamp results in fewer persistent neuropsychological deficits than multiple clamp or off-pump coronary artery bypass grafting.

BACKGROUND: In coronary artery bypass grafting (CABG) patients, neuropsychological deficits that are present from the time of the operation through 6 months postoperatively are considered permanent and represent organic brain damage related to the operation. We hypothesized that changes in our surgical method would reduce persistent deficits. METHODS: From 1999 to 2004, consenting CABG patients were randomly assigned to multiple aortic cross-clamp or single aortic cross-clamp technique. An additional contemporary group of patients treated with off-pump CABG was studied. All patients underwent an 11-part neuropsychologic examination preoperatively, and at 1 week, 6 weeks, and 6 months postoperatively. One hundred seven patients with no postoperative neurologic deficits had neuropsychologic examinations at all four testing periods. RESULTS: Off-pump CABG patients were significantly younger (60 +/- 11 years) than multiple aortic cross-clamp (66 +/- 8 years) and single aortic cross-clamp (64 +/- 9 years; p < 0.05) patients. At 6 months, 26% of 27 multiple aortic cross-clamp patients had neuropsychological deficits, 27% of 26 off-pump CABG patients had neuropsychological deficits, and only 9% of 54 single aortic cross-clamp patients had neuropsychological deficits (p = 0.067 versus multiple aortic cross-clamp and off-pump CABG). CONCLUSIONS: These results suggest that surgical technique is very important in determining cognitive outcome after CABG. Cardiopulmonary bypass is not the most important factor in determining outcome and when carefully performed with single cross-clamp and minimal aortic manipulation is equal or may be superior to off-pump operation. We suspect that mild hypothermia in on-pump surgery is additionally neuroprotective, a factor that should be taken into account when planning an operation.

The risk of death from heart disease in patients with nonsmall cell lung cancer who receive postoperative radiotherapy: analysis of the Surveillance, Epidemiology, and End Results database.

BACKGROUND: This study was designed to investigate whether the mortality from heart disease, a manifestation of intercurrent disease after postoperative radiotherapy (PORT), has decreased over time for patients with nonsmall cell lung cancer (NSCLC). METHODS: The 17-registry 1973 to 2003 dataset from the National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) Program was used to create a cohort of patients with NSCLC who had evidence of ipsilateral lymph node involvement diagnosed from 1983 to 1993 and who underwent pnuemonectomy/lobectomy (n = 6148 patients). Heart disease mortality was the primary endpoint: Deaths from other causes were censored, and surviving patients were censored at 10 years. The independent variable was PORT use, and adjustment variables included age at diagnosis, sex, race, year of diagnosis, laterality, location, histology, and the operation performed. RESULTS: Multivariate analysis revealed that PORT use was associated with an increase in heart disease mortality (hazards ratio [HR], 1.30; 95% confidence interval [95% CI], 1.04-1.61; P = .0193) along with older age, male sex, African-American race, and earlier year of diagnosis. The association was confirmed in the cohort that was diagnosed from 1983 to 1988 (HR, 1.49; 95% CI, 1.11-2.01 [P = .0090]) but not for the cohort that was diagnosed from 1989 to 1993 (HR, 1.08; 95% CI, 0.79-1.48 [P = .6394]). CONCLUSIONS: The results from this study demonstrated that the risk of heart disease mortality associated with PORT has declined in more recent years. This may be secondary to improvements in the treatment planning and delivery of thoracic radiotherapy. Properly designed, prospective, adjuvant trials will be needed to verify these findings.

Single crossclamp improves 6-month cognitive outcome in high-risk coronary bypass patients: the effect of reduced aortic manipulation.

OBJECTIVE: We hypothesized that a strategy that reduced aortic manipulation would reduce the incidence of cognitive deficits in patients undergoing coronary artery bypass grafting compared with the "traditional" approach and that neurobehavioral outcomes with the reduced aortic manipulation strategy would approach those obtained with off-pump coronary artery bypass surgery. METHODS: Consenting high-risk patients (those with older age, diabetes, or hypertension) scheduled for coronary artery bypass grafting and cardiopulmonary bypass were randomly assigned to 1 of 2 aortic management protocols: (1) a traditional approach in which distal anastomoses were accomplished while the aorta was crossclamped but in which proximal anastomoses were sewn while a partial occlusion clamp was applied to the aorta (multiple aortic clamping group) or (2) a reduced aortic manipulation approach in which the aorta was clamped a single time with a reduced-pressure clamp (single aortic clamping group) and the partial occlusion clamp was not used. A contemporaneous group of patients undergoing off-pump coronary artery bypass surgery without cardiopulmonary bypass was also enrolled. Subjects in all 3 groups underwent neurologic and neuropsychological testing before and after surgery. After randomization, patients assigned to either approach could be changed to another strategy if the attending surgeon determined that patient safety demanded this change. The study design anticipated that surgical techniques would evolve over the course of patient enrollment and anticipated that some patients would have intraoperative echocardiographic findings that would demand that the traditional approach (eg, severe aortic atherosclerosis) or the reduced manipulation protocol (eg, severe ischemia or poor left ventricular function) be abandoned. Thus, an unequal distribution of patients was expected. By surgeon decision, 20 of 84 multiple aortic clamping patients crossed over to single aortic clamping, and 3 of 85 single aortic clamping patients switched to multiple aortic clamping. Eligible patients had a battery of neuropsychological tests before surgery and at 6 months after surgery. A 20% decrement in 2 or more tests was defined as a neuropsychological deficit. RESULTS: [table: see text]. CONCLUSIONS: A surgical strategy designed to minimize aortic manipulation can significantly reduce the incidence of cognitive deficits in coronary artery bypass grafting patients compared with traditional techniques. In this series, the results of the reduced aortic manipulation strategy were not significantly different from those in patients having off-pump coronary artery bypass surgery, thus emphasizing surgical technique as the primary cause of brain damage in coronary artery bypass grafting patients.

A prospective evaluation of the impact of 18-F-fluoro-deoxy-D-glucose positron emission tomography staging on survival for patients with locally advanced esophageal cancer.

PURPOSE: To determine the impact of 18-F-fluoro-deoxy-D-glucose positron emission tomography (FDG-PET) in the staging and prognosis of patients with locally advanced esophageal cancer (LAEC). METHODS AND MATERIALS: Between January 2000 and October 2004, all patients with LAEC evaluated in the Department of Radiation Oncology were considered for enrollment into a Phase II trial of preoperative chemoradiation. Entry required a staging whole-body FDG-PET scan. RESULTS: One hundred ten consecutive patients were evaluated; 38 were ineligible for reasons including treatment elsewhere, prior malignancy, or refusal of treatment. After conventional staging (clinical examination, endoscopic ultrasound, and chest/abdominal computerized tomography), 33 patients were ineligible because of metastatic disease or poor performance status. Of the remaining 39 patients, 23 were confirmed to have LAEC after FDG-PET staging and were treated in the Phase II trial (Cohort I). Sixteen patients, however, had FDG-PET findings consistent with occult metastatic disease and were deemed ineligible for the trial but were treated with curative intent (Cohort II). The 2-year survival rate for the 23 patients in Cohort I was 64%, compared with 17% (p=0.003) for patients in Cohort II (FDG-PET positive). CONCLUSIONS: More than one-third of patients determined to have LAEC with conventional staging were upstaged with the use of FDG-PET. Despite comparable therapy, upstaging with FDG-PET predicts poor 2-year survival.

Pathologic complete response may not represent the optimal surrogate for survival after preoperative therapy for esophageal cancer.

BACKGROUND: We designed a phase II trial to examine the benefit of preoperative hyperfractionated radiation therapy (XRT) and concurrent chemotherapy for patients with locally advanced esophageal cancer (LAEC). AIM OF STUDY: The pathologic complete response (pCR) was the primary endpoint to estimate efficacy. METHODS: Twenty-three patients with LAEC received twice-daily XRT during wk 1 and 5 and once-daily XRT during wk 2-4 (59 Gy). Cisplatin (100 mg/m(2)) was given on d 1, while 5-fluorouracil (1000 mg/m(2)) was given by continuous infusion the first and fifth weeks of the XRT. RESULTS: The pCR for the 19 patients undergoing esophagectomy was 16%. The study was closed at the interim analysis having not met the required minimum pCR rate of 20%. Hematologic toxicities consisted of grades III and IV neutropenia observed in 33% and 14% of patients, respectively. Grade III nausea and vomiting was seen in 38% of patients. One grade V pulmonary toxicity occurred. The median survival was 44.6 mo with 65% of patients alive at 2 yr. CONCLUSIONS: The pCR rate in this trial did not meet the predetermined statistical minimum. With the encouraging 2-yr survival, it is not clear that pCR is a reliable surrogate endpoint to discern treatment efficacy.

Polypoid hyperplasia of the larynx misdiagnosed as a malpositioned laryngeal mask airway.

Polypoid hyperplasia of the vocal cords, associated with smoking, reflux, and vocal cord abuse, results in inflammation and edema. This condition can produce partial airway obstruction during positive pressure ventilation.
