Instilled bleomycin and thoracostomy were utilized in 38 patients with malignant pleural effusions; the therapy produced a complete or partial response rate of 63%. Toxicity was minimal. In patients with intraperitoneal effusions, bleomycin instillation after drainage produced a complete or partial response in 36%. One patient had severe hypotension and fever. Patients with ovarian and breast carcinoma responded best, among them, effusions were controlled in greater that 70%. Because of its low systemic toxicity, absence of marrow toxicity, and virtual absence of discomfort, we think that the local instillation of bleomycin is indicated in the management of malignant effusions.

Surgery is the modality of choice in curative treatment for cancer of the colon and rectum. Since a majority of the patients present advanced disease where the surgical outlook is poor, adjuvant therapy may be warranted. Clinical and experimental data demonstrate the benefits from preoperative radiation therapy and some clinical reports indicate the beneficial effects of postoperative radiotherapy. Two national studies are underway to determine the effectiveness of preoperative radiation therapy in moderate doses. A similar study is suggested to establish the effectiveness of postoperative radiation therapy.For patients who are poor surgical risks, or for a tumor which is considered to be inoperable, and in a selected group, radiation therapy can be used as a curative procedure. Advantages include eliminating the need for a permanent colostomy. In case of failure, electrocoagulation and abdominal perineal resection are still available alternatives.A modest amount of radiation therapy can afford maximum palliation with minimum discomfort to the patient. About 80-90 percent of patients with pain and bleeding and 50 percent of patients with symptomatic liver metastasis respond favorably.

Pleural and peritoneal effusion secondary to primary malignancy is a significant problem in the management of the cancer patient. Respiratory embarrassment and discomfort associated with the formation and collection of fluid in the chest and abdomen are among the most distressing symptoms encountered as a result of malignant disease. The guidelines for treatment should be based on respiratory symptoms, and with the understanding that the procedure is palliative. Both surgical and medical forms of treatment have been used. These include thoracostomy-tube drainage alone or with the instillation of antimicrobial agents. Pleurectomy is effective but should be reserved for situations in which conservative approaches have failed. Antitumor agents, such as nitrogen mustard, are effective but toxic. The mode of action of antineoplastic agents is related to their ability to cause pleural sclerosis and obliterate the pleural space. Systemic chemotherapy and external beam radiation are rarely effective. The intracavitary application of radioactive colloids has been used since 1945. Colloidal radioactive gold Au 198 has been replaced by the pure beta emitter, colloidal chromic phosphate P 32. Instillation of a colloidal suspension of radioactive phosphorus represents a significant and effective palliative therapeutic modality for malignant effusion.

The use of fine needle aspiration biopsy of solitary osteolytic-type bone metastases in 24 patients is described. A positive diagnosis of malignancy was obtained in 21 patients, as the softness of the osteolytic lesion yielded enough cell material for cytologic examination. No complications were encountered. The procedure can be performed with ease, even on an outpatient basis, without discomfort to the patient.

Peritoneoscopy was carried out in 352 cancer patients with clinical suspicion of liver involvement in most cases. Principally because of patient discomfort, adequate liver biopsy was obtained in only 66% of 240 patients who underwent peritoneoscopy under local anesthesia while, under general anesthesia, biopsies could be taken in 90% of 112 patients. When the liver was macroscopically free of disease, the yield of positive peritoneoscopy was minimal regardless of the number of blind deep biopsies. Peritoneoscopy provided histologic demonstration of hepatic invasion in a total of 55 patients. Seven false-negative examinations out of 19 negative peritoneoscopies (36%) were identified by subsequent laparotomy or autopsy within 2 months. These preliminary data, although difficult to interpret in terms of accuracy of the method, point to the possible contributions of peritoneoscopy in detecting liver metastases.

A clinical trial of the oral form of VP 16-213 (NSC-141540), a semisynthetic podophyllotoxin, was undertaken. In 20 patients, treatment was started at 200 mg/day p.o. for 5 days; courses were repeated after a rest period of 16 days. Five patients were treated at the same dose, repeated with only 9-day rest periods. Subsequently, 65 patients were given 300-400 mg/day for 5 days, with rest periods of 9 days between courses. The side effects encountered included anorexia, nausea and vomiting, stomatitis, diarrhea, leukopenia, thrombocytopenia, alopecia, and pruritus. Substernal discomfort with or without palpitations was reported by 18 patients; no explanation for this symptom could be found. No complete remissions (CR) were observed. Parital remissions (PR) and improvement (IMP) were seen as follows: small cell carcinoma, lung (10 patients)--2 PR, 3 IMP; adenocarcinoma, lung (4 patients)--1 PR; alveolar cell carcinoma, lung (1 patient)--1 IMP; mesothelioma (4 patients)--1 IMP; ovarian cancer (12 patients)--3 PR, 3 IMP; breast cancer (20 patients)--4 IMP; colon cancer (8 patients)--2 IMP; bladder cancer (4 patients)--2 IMP; histiocytic lymphoma (7 patients)--2 PR, 3 IMP; chronic myeloid leukemia (1 patient)--1 IMP.

Plasma of a patient with metastatic colon carcinoma was perfused over Formalin and heat-killed S. aureus, in an extracorporeal filtration apparatus, in order to nonspecifically remove IgG and its complexes. Twenty ex vivo absorption procedures were done, over a five-month period, with a minimum of discomfort to the patient. Extracorporeal perfusion of plasma on S. aureus effectively reduced the levels of IgG and immune complexes in the perfused plasma. The nonspecific removal of IgG resulted in 1) slight biochemical alterations in the serum, 2) a transient reduction in the serum blocking activity and appearance of complement-dependent serum cytotoxicity, 3) an increase in the serum IgM levels, 4) a transient increase in the Ig surface-bearing lymphocytes and a decrease in "E" rosetting lymphocytes in the first 24-48 hours postperfusion, particularly during the early treatments, 5) an improvement in general condition of the patient and decrease in tumor size, and 6) histological changes in the tumor consistent with tumor destruction. The potential problems and clinical applications of procedures involving ex vivo specific or nonspecific immunoabsorbents are discussed.

The colorectal cancers in greater part grow out of polyps, which can be looked upon as optional precancerosis. Own results together with literature-reports show a distinct increase of the frequency of polyps beyond the age of fortyfive. The only digital palpation of the rectum is insufficient; it leads to the diagnosis of a rectum polyp only in 15.5%, to the diagnosis of a cancer in 13% of cases. With the rectosigmoidoscopy however the diagnosis is successful in 70% of cases. The percentage of precancerous polypous alterations detected by rectosigmoidoscopy is approximately the same in medical check-up as in directed examinations of patients with anorectal discomfort. A restriction of rectosigmoidoscopy to the last-named group of persons is not any longer justified. The polypectomy in the rectum is a real cancer-prevention.

A behavioral observation study of 14 children with cancer treated in a laminar airflow protected environment (PE) unit was done over a period of 2 years. A total of 3629 observations were completed, and results related to perception, sleep, intellectual functioning, physical discomfort, mood, management problems, activity patterns, social-communicative behavior, and sedation are reported. In general, despite evidence from the literature that sensory deprivation and social isolation can cause severe disturbance of the sensory apparatus, no debilitating or long-term psychological effects related to prolonged PE treatment were noted. The differences between PE and deprivation-isolation contexts are discussed, and the need for psychosocial support of these patients is emphasized.

A modified method of catheterization of the umbilical vein differs from other methods, for at the dismissal of the patient from the hospital the peripheral end of the polyvinylchloride catheter filled with maiodil is sealed and inserted under the skin, which permits to keep the catheter in the umbilical vein for several years, taking out its end periodically from under the skin for introduction of necesary drugs in case of cancer and liver cirrhosis. The catheter does not cause any discomfort and prevents the umbilical vein and surrounding tissues against infection. The suggested method has been applied in 64 patients without any related complications.
