Late stage (III and IV) non-small cell cancer of the lung: results of surgical resection at Inova Fairfax Hospital.

One hundred forty-two patients underwent surgery and related treatment for advanced stage (III, IV) non-small cell cancer of the lung. One hundred seventeen patients underwent up-front surgery, with a hospital mortality rate of 1.7% (2/117). Kaplan-Meier 5-year survival in this group was 31% (+/- 5). Twenty-five patients underwent neoadjuvant therapy followed by surgical resection, with respective rates of hospital mortality, complete pathologic response, and major pathologic response of 0%, 16%, and 64%. Kaplan-Meier 5-year survival in this latter group was 34% (+/- 11). Of the 16 patients undergoing neoadjuvant therapy who had complete pathologic response or significant downstaging from stage III disease, Kaplan-Meier 5-year survival was 61% (+/- 15). Three clinical observations of interest emerged regarding survival. First, in those patients with postresection FEV1 < 1.0 L, hospital mortality rate was 20%, and there were no 5-year survivors (P < 0.0001). Second, where neoadjuvant therapy was associated with complete pathologic response or significant downstaging of disease, there was a trend for improved survival in the downstaged group, but it did not reach statistical significance (P = 0.14). Third, adjuvant therapy was associated with improved 5-year survival (P = 0.03), particularly for combination chemotherapy and radiotherapy (P = 0.02).

A pragmatic and successful approach to treating nonsmall-cell lung carcinoma.

Lung cancer is the single leading cause of cancer deaths for men and women combined. Nonsmall-cell lung carcinoma (NSCLC), which results largely from smoking tobacco, accounts for 87% of all lung cancer cases. Methods of patient selection, preoperative and intraoperative care, and postoperative outcomes for patients with NSCLC who were treated from 1991 through 2003 at Inova Fairfax Hospital are discussed. All patients were treated with surgery, some selectively and progressively with a combination of preoperative neoadjuvant therapy, to try to downstage the disease to make complete resection feasible. Outcomes from this data collection period match or exceed the best results for treatment of late-stage (ie, III and IV) disease reported anywhere to date.

Multimodality treatment for esophageal cancer: the role of surgery and neoadjuvant therapy.

Treatment of esophageal cancer has traditionally included surgery as the initial modality. Neoadjuvant chemoradiation therapy has been introduced with the goal of downstaging tumors before surgical resection; however, its role in esophageal cancer remains controversial. We report 116 patients who underwent esophagogastrectomy with reconstruction for carcinoma of the esophagus or esophagogastric junction over a 10-year period (January 1, 1990 to June 1, 2001). Forty patients underwent neoadjuvant radiation and chemotherapy followed by surgery. Hospital mortality in this group was 7.5 per cent, complete pathologic response (CPR) was 37.5 per cent, and overall 3- and 5-year survival rates were 47 and 38 per cent. Five-year survival in the 15 patients with CPR was 85 per cent. Five patients underwent neoadjuvant single-agent therapy (four chemotherapy and one radiation) followed by surgery, and none survived to 3 years. Seventy-one patients underwent surgery without neoadjuvant therapy. Hospital mortality in this group was 1.4 per cent, with 3- and 5-year survival of 21 and 17 per cent--a decreased long-term survival compared with the neoadjuvant therapy group despite the observation that patients who underwent neoadjuvant therapy had a larger tumor size on presentation (5.5 +/- 0.4 cm vs 3.8 +/- 0.2 cm; P = 0.002). Squamous cell carcinomas seemed to be more responsive to neoadjuvant radiation and chemotherapy followed by surgery than were adenocarcinomas, with a CPR of 44.4 versus 35.5 per cent; however, 5-year survival rates in these complete responders were not significantly different (100% and 78%, respectively; P = 0.97). We report that esophagogastrectomy in conjunction with neoadjuvant therapy results in increased survival compared with surgery without neoadjuvant therapy (P < 0.01), although there may be an increased perioperative mortality associated with neoadjuvant therapy. Further studies are needed to evaluate the role of preoperative chemoradiation and to better identify the pretreatment characteristics of patients with a complete pathological response.

Thoracic esophageal perforations.

BACKGROUND: Recognition of the importance of early diagnosis and aggressive, definitive surgical intervention has brought about a dramatic decline in mortality related to distal esophageal perforation. METHODS: We retrospectively analyzed all cases of thoracic esophageal perforation diagnosed at our hospital from September 1, 1979, through April 1, 2001. The study group consisted of 62 patients (43 men) with a mean age of 58.8 years (range, 20-92 yr). RESULTS: In the group of 39 patients with early diagnosis (< or = 24 h), hospital survival was 87%, which increased to 93% when early diagnosis was combined with aggressive surgical treatment Among the 23 patients with late diagnosis (> 24 h), survival approached 70%. Yet, in patients who were treated aggressively with surgery, survival was almost 90% despite delayed diagnosis. CONCLUSION: We recommend aggressive, definitive surgery for thoracic esophageal perforations, whether diagnosed early or late. A variety of options are discussed with regard to complicated presentations.

Mediastinal staging of non-small cell lung carcinoma using computed and positron-emission tomography.

BACKGROUND: We evaluated the accuracy of computed tomography (CT) and positron-emission tomography (PET) in the mediastinal staging of non-small cell lung cancer. METHODS: Between May 14, 1999, and November 28, 2000, computerized tomography (CT) and positron-emission tomography (PET) were used to clinically stage 94 consecutive patients with non-small cell carcinoma of the lung (NSCCL). All patients underwent subsequent surgical staging with mediastinoscopy, anterior mediastinotomy, and/or thoracotomy with mediastinal lymphadenectomy. RESULTS: Overall accuracy was the same for both procedures. False-negative results occurred 3 times more often with CT; false-positive results occurred twice as often with PET. Sensitivity and specificity were 64% and 94%, respectively, for CT, versus 88% and 86%, respectively, for PET. Positive and negative predictive values were 80% and 88%, respectively, for CT, versus 71% and 95%, respectively, for PET. CONCLUSION: In addition to routine use of CT, PET seems to achieve high negative predictive value in the evaluation of mediastinal disease; PET seems particularly helpful in assessing absence of tumor in bulky nodes after neoadjuvant chemotherapy and/or radiotherapy.
