Forty-one patients with small cell carcinoma of the uterine cervix were evaluated and treated at the University of Kentucky Medical Center from 1962 to 1974. Eighteen patients (44%) developed widespread metastases and died of recurrent cancer within 2 years of therapy. Common sites of metastases included the lung, liver, and bone. There was a significantly lower incidence of lymphoplasmacytic infiltration in small cell cancers than the keratinizing or nonkeratinizing squanmous cell carcinomas of the cervix. In addition, there was a significant increase in the number of unstimulated regional lymph nodes in patients with small cell cancer when compared with the lymph nodes of patients with the other cell types of cervical cancer. These data suggest that small cell cancer of the cervix is a highly aggressive tumor similar to small cell carcinoma of the lung and behaves quite differently from other types of squamous cell carcinoma of the cervix. Radiation therapy was superior to radical surgery in eradicating pelvic disease, but prospective studies need to be undertaken to determine the effect of adjunctive chemotherapy in patients with this rare tumor.

Most of the symptoms from a malignant tumor are caused by local invasion by the tumor, or obstruction, either at the site of the primary disease or by metastases. However, tumors can produce symptoms at a remote site. Patients with gastrointestinal malignancy may present with symptoms which include dysphagia, nausea, vomiting, abdominal pain, diarrhea, bleeding and ascites. Palliation gastrectomy delays or prevents these symptoms. About 30% of gastric carcinomas are inoperable at the time of presentation. Chemotherapy is rarely effective in the palliation of gastric carcinoma. Laser irradiation can be delivered to assay site accessible to fibreoptic endoscopy, which is an advantage over endocavity irradiation or diathermy fulguration. Ascites is a common and disabling implication in patients with advanced malignant disease. Spironolactone will increase urinary sodium excretion significantly and control their ascites. If spironolactone fails to control, useful control can be achieved by draining the ascites. Patients with carcinoma of the lung may present with symptoms that include cough, bloody sputum and dyspnoea. Pain in the chest wall is usually secondary to invasion of the parietal pleura, ribs or intercostal nerves. Lesions in the medial portion of the right upper lobe, or mediastinal metastases, may invade or compress the superior vena cava, causing venous hypertension with oedema of the head and arms. The patients may complain of dyspnoea, dysphagia, stridor and headaches. Radiotherapy can be expected to improve the quality of life for these patients. Successful palliation of symptoms is almost related to tumor regression. The problems of obstruction and bleeding from malignant tumor is common. Recently, laser techniques have been applied to aid in palliation of these problems. Malignant effusion may occur early and be the first signs of metastases. The aim of therapy is to evacuate the fluid and induce pleural adhesion. One of the sad situations that we have to face is the patient with recurrent cancer which complains of various symptoms. The relief of symptoms is the most important palliative therapy to them.

A 17% frequency of cytologically negative pericardial effusion (CNPE), accompanied in some cases by tamponade, occurred a median of 12.6 months from the onset of treatment for localized small-cell carcinoma of the lung. CNPE was apparently caused by toxicity of radiation/chemotherapy treatment rather than recurrent cancer. The occurrence of CNPE does not appear to represent enhanced toxicity of immediate (as opposed to delayed) concurrent chemoradiotherapy, but may be a consequence of the superior survival status of patients treated in this way. The onset of chest pain and/or dyspnea associated with increase in cardiac silhouette and positive echocardiogram allowed accurate diagnosis. Each instance was relatively easily managed by catheter drainage, and, for some patients, with the addition of nonsteroidal antiinflammatory drugs. It is important to recognize the possibility that a radiation/chemotherapy-related syndrome of pericardial effusion/tamponade may occur so that early diagnosis can be made and the risk of fatal tamponade avoided.

The clinical improvement obtained with combination treatment has modified the therapeutic approach of lung cancer in HIV-positive patients. Aggressive surgical treatment has become a viable option for those patients in whom the CD4(+) cell count was greater than 200 lymphocytes/mm(3). We recently extended our surgical indications to include two HIV-positive patients with lung cancer (stage IIIA and IIB) and low (<200 lymphocytes/mm(3)) CD4(+) count. Both patients underwent a lobectomy and mediastinal nodal dissection. The postoperative course was uneventful. No evidence of recurrent cancer was seen at 12 and 20 months after the operation. Based on this limited experience, we conclude that a low CD4(+) count should not represent, per se, an exclusion criterion for the surgical treatment of pleuropulmonary conditions in HIV-positive patients.
