Pulmonary resection after chemotherapy and concurrent full-dose radiotherapy (>59 Gy) has previously been associated with unacceptably high morbidity and mortality. Subsequently neoadjuvant therapy protocols have used reduced and potentially suboptimal radiotherapy doses of 45 Gy. We report a series of 40 patients with locally advanced non-small-cell lung cancer who successfully underwent pulmonary resection after receiving greater than 59 Gy radiation and concurrent chemotherapy. Operative results and midterm survival follow-up are presented. ⋯ Pulmonary resection may be performed safely after curative intent concurrent chemotherapy and radiotherapy to greater than 59 Gy. High pathologic complete response rates and sterilization of mediastinal lymph nodes were observed accompanied by highly favorable survival rates. This experience, though promising, will require confirmation in a prospective multiinstitutional clinical trial.

We are analyzing our experience with treatment of desmoid tumors of the chest wall and adjacent structures. ⋯ Desmoid tumors involving the chest and adjacent structures are locally aggressive tumors with a high recurrence rate. Wide radical resection should be attempted whenever possible. Positive margins at resection, reoperation and postoperative radiation are associated with a high risk of local recurrence.

We assessed the clinical outcome and conducted an angiographic study of total arterial off-pump coronary artery bypass grafting for revascularization of the total coronary system. ⋯ Total arterial off-pump coronary artery bypass yielded good clinical results and an excellent patency rate of revascularization for the total coronary system.

The number or ratio of lymph node metastases detected by hematoxylin & eosin (H&E) staining is the most important predictor of survival in esophageal cancer. The survival effect of lymph node metastases detected on immunohistochemistry (IHC) is controversial. My colleagues and I hypothesized that the extent of nodal disease determined by both H&E and IHC examination would more accurately predict survival than either technique alone. ⋯ IHC staining techniques can identify nodal metastases missed by routine H&E examination in a large number of patients. The combination of H&E and IHC examination is useful in patients with less than 10% nodal involvement by H&E examination in that IHC detection of micrometastases allows classification into low-risk (> 75% survival) and high-risk (< 15% survival) groups. IHC-detected micrometastases are not of prognostic importance in N0 patients or those with greater than 10% nodal metastases on H&E.
