Combined pectoralis flap and gastric pull-up for pharyngeal reconstruction.

Background: The gastric transposition flap, "gastric pull-up," is one of the standard techniques of reconstruction after total laryngopharyngectomy. Under certain circumstances, this method may provide insufficient tissue for a tension-free closure. In these circumstances, the surgeon could either close under tension, risking the viability of the flap and probable fistula; create a pharyngostome; or recruit additional tissue.

A universal method for the mutational analysis of K-ras and p53 gene in non-small-cell lung cancer using formalin-fixed paraffin-embedded tissue.

The p53 tumor suppressor gene has been found to be altered in almost all human solid tumors, whereas K-ras gene mutations have been observed in a limited number of human cancers (adenocarcinoma of colon, pancreas, and lung). Studies of mutational inactivation for both genes in the same patient's sample on non-small-cell lung cancer have been limited. In an effort to perform such an analysis, we developed and compared methods (for the mutational detection of p53 and K-ras gene) that represent a modified and universal protocol, in terms of DNA extraction, polymerase chain reaction (PCR) amplification, and nonradioisotopic PCR-single-strand conformation polymorphism (PCR-SSCP) analysis, which is readily applicable to either formalin-fixed, paraffin-embedded tissues or frozen tumor specimens.

Chemoradiotherapy of esophageal carcinoma.

Background: Chemoradiotherapy has demonstrated efficacy in esophageal cancer but rarely is curative. To improve local control and decrease metastases, a 7-month regimen was used with standard-dose radiotherapy (RT), cisplatin (DDP), and continuous infusion (CI) 5-fluorouracil (5-FU) in patients with locoregional squamous/adenocarcinoma of the esophagus.

Methods: Initial treatment consisted of RT to the esophagus (4000-5000 cGy) for 5-6 weeks, CI 5-FU (300 mg/m2/day) concurrent with RT, and DDP (25 mg/m2/day x 3) for Days 1-3 and 21-23.

Diagnosis of acute diffuse pulmonary infiltrates in immunosuppressed patients by open biopsy of the lung.

Herein is a review of the results of open biopsies of the lung performed upon immunosuppressed patients between the years 1982 and 1988. The goal was to assess the safety and value of the procedure on a group of patients who are many times in extremis because of multiorgan failure. Obtaining the correct diagnosis and establishing treatment poses a challenge.
