Pneumoperitoneum increased implantation of free intra-abdominal cancer cells at wound sites on the abdominal wall or within the abdominal cavity in this animal model. The use of pneumoperitoneum during laparoscopy in patients with colon cancer should only be performed in a protocol setting to evaluate the effect of pneumoperitoneum on the treatment of cancer.

FDG-PET is more sensitive than CT in the clinical assessment of patients with recurrent or metastatic CRC, and provides an accurate means of selecting appropriate treatment for these patients.

Although some patients with Paget's disease might be well treated by breast conservation therapy, many patients have underlying multifocal carcinoma (including invasive cancer), which can be inapparent by examination and mammography. Selecting candidates with disease amenable to complete excision without mastectomy is problematic.

One hundred thirty‐three patients with 154 treated malignant pleural effusions were reviewed. Carcinoma of the breast, bronchogenic carcinoma, and lymphomas were the most frequent tumors causing malignant pleural effusion. Cytologies were positive in 67% of the 125 effusions examined. Local treatment consisted of thoracentesis, tube thoracostomy with or without nitrogen mustard instillation, irradiation, or pleurectomy. Patients were followed for recurrence of effusion and return of symptoms for an average of 6 1/2 months. Statistical analysis showed that 37% of 66 hemithoraces (60 patients) treated with tube thoracostomy and nitrogen mustard were free of effusion 3 months after treatment, and 29% 6 months after therapy. Fifty‐three percent of these patients were asymptomatic at 6 months, and 39% at 1 year after treatment. Thoracentesis with or without nitrogen mustard instillation was distinctly inferior to the tube and nitrogen mustard method. Pleurectomy in selected cases proved worthwhile.
