Occult alveolar haemorrhage in bronchopulmonary Kaposi's sarcoma.

Evidence of occult alveolar haemorrhage was sought by Perls's staining of bronchoalveolar lavage fluid to detect haemosiderin laden macrophages in 63 human immunodeficiency virus positive (HIV-1) men who underwent bronchoscopy. Twenty three patients had bronchopulmonary Kaposi's sarcoma; occult alveolar haemorrhage was present in 16 of these (including two in whom no tracheobronchial lesions were evident at bronchoscopy, but in whom the diagnosis was confirmed at necropsy). Forty patients had other diagnoses including Pneumocystis carinii pneumonia and bacterial pneumonia; 18 had occult haemorrhage. Occult alveolar haemorrhage seems to be a non-specific finding in HIV-1 positive men undergoing bronchoscopy.

Bronchopulmonary Kaposi's sarcoma in patients with AIDS.

BACKGROUND: Kaposi's sarcoma in HIV antibody positive patients may affect the lungs. This study describes the presentation, chest radiographic appearances, and pulmonary function test abnormalities in patients with AIDS who had tracheobronchial Kaposi's sarcoma. METHODS AND RESULTS: Twenty nine (8%) of 361 consecutive HIV antibody positive patients undergoing bronchoscopy for respiratory symptoms had tracheobronchial Kaposi's sarcoma. Eight patients had intercurrent infections and one had previously received chemotherapy for cutaneous Kaposi's sarcoma; these patients were excluded. Seven of the remaining 20 patients had localised Kaposi's sarcoma (lesions confined to the trachea or the subsegments of one lobe) and 13 had widespread Kaposi's sarcoma (affecting the trachea and one lobe or the subsegments of more than one lobe); 19 patients also had cutaneous and palatal Kaposi's sarcoma. Seven patients, four with widespread disease, had a normal radiograph. All patients had reduced transfer factor (TLCO) and transfer coefficient (KCO) but only those with widespread disease had reductions in forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and peak expiratory flow (PEF). Follow up pulmonary function testing in seven patients (median three months later) showed further reductions in TLCO. All four patients who received no treatment had progressive radiographic abnormalities; bronchoscopy in two patients showed progressive tracheobronchial disease, and two patients had further reductions in FEV1 and FVC. In three patients treated with chemotherapy palliation of symptoms was achieved but two had further reductions in FEV1 and FVC and the radiograph deteriorated. Bronchoscopy showed regression of disease in only one patient. CONCLUSION: Pulmonary Kaposi's sarcoma produces abnormalities of TLCO even in patients with localised disease; airflow obstruction may occur in patients with widespread disease. Bronchoscopic reassessment of the extent of disease may not accurately reflect response to chemotherapy.

Olfactory sensations produced by high-energy photon irradiation of the olfactory receptor mucosa in humans.

During irradiation of volumes that incorporate the olfactory system, a proportion of patients have complained of a pungent smell. A retrospective study was carried out to determine the prevalence of this side-effect. A questionnaire was sent to 40 patients whose treatment volumes included the olfactory region and also to a control group treated away from this region. The irradiated tumor volumes included the frontal lobe, whole brain, nasopharynx, pituitary fossa, and maxillary antrum. Of the 25 patients who replied, 60% experienced odorous symptoms during irradiation. They described the odor as unpleasant and consistent with ozone. Stimulation of olfactory receptors is considered to be caused by the radiochemical formation of ozone and free radicals in the mucus overlying the olfactory mucosa.

A Medical Research Council phase II trial of alternating chemotherapy and radiotherapy in small-cell lung cancer. The Medical Research Council Lung Cancer Working Party.

In a non-randomised study in six centres in the UK, 24 patients with previously untreated small-cell lung cancer of limited extent were treated with a regimen of alternating chemotherapy and radiotherapy to assess response, toxicity, and the feasibility of applying such a regimen on a multicentre basis in the UK. The intention was to give six courses of chemotherapy on five consecutive days at 4-week intervals: etoposide 75 mg m-2 on days 1, 2, and 3; doxorubicin 40 mg m-2 on day 1; cisplatin 100 mg m-2 on day 2; and cyclophosphamide 300 mg m-2 on days 2, 3, 4 and 5. A dose of 20 Gy thoracic radiotherapy was to be given following the 2nd and the 3rd courses, and one of 15 Gy following the 4th course. After 12 patients had been admitted, the cisplatin dosage was reduced to 80 mg m-2 because of unacceptable toxicity. Two patients were withdrawn during treatment on review of their histology because their diagnosis was found to be incorrect. Only one patient of the 12 treated with cisplatin 100 mg m-2 was able to complete treatment, compared with five of the eligible ten given the lower dosage. Among the 22 patients with confirmed small-cell disease, a complete response was reported in 14 (64%) and a partial response in a further three (total response rate 77%). Myelosuppression was the commonest serious adverse effect. It occurred in 19 of the 24 patients and gave rise to septicaemia in five, four of whom were receiving the higher cisplatin dose. Sixteen patients required blood transfusion and ten platelet transfusion. Vomiting, oesophagitis, and peripheral neuropathy occurred in 12, four and four patients, respectively, and radiation pneumonitis developed in two. Treatment was considered a contributory cause of death in four. The working party concluded that the alternating regimen was feasible in only a small proportion of centres in the UK, and decided not to embark on a multicentre randomised trial comparing alternating with conventional scheduling.

A possible role for ultrasound of the axilla in staging primary breast cancer.

The axillae of 30 patients with primary breast cancer (Stage I and II) were prospectively examined in this pilot study using ultrasound. No patient had palpable axillary lymph nodes on clinical examination. Treatment had involved wide local excision, but no prior form of surgical dissection had been performed on the axilla. Using the contralateral axilla as an internal control, lymph nodes were observed in the ipsilateral axilla alone on ultrasound in 8/30 patients (27%). Following radical irradiation of the breast and local lymph drainage areas, 2/8 patients of the group with observed lymph nodes have relapsed, one with systemic disease and the other with local recurrence in the breast, after a minimum follow-up of 12 months. No patient without observed nodes has recurred. This difference does not reach statistical significance. This technique merits further investigation as an adjunct to current staging procedures for early breast cancer.

Non-Hodgkin's lymphoma associated with the acquired immune deficiency syndrome: a report of five cases.

We report a series of five HIV positive patients with histologically proven non-Hodgkin's lymphoma. The paper illustrates the difficulties experienced in both the clinical diagnosis and its histological confirmation. In this series we have confirmed the predominance of aggressive histological variants and the high frequency of extra-nodal involvement. The prognosis despite treatment was poor; only one patient entered complete remission and the mean survival was only 4.3 months.

Diagnosis and treatment of Kaposi's sarcoma.

Kaposi's sarcoma occurs in the non-classical form in immunosuppressed patients in non-HIV patients in Africa and in patients infected with HIV. The latter group are now the most common. The treatment of Kaposi's sarcoma in AIDS patients must be seen in the context of their general condition. Symptomatic treatment by radiotherapy and low dose chemotherapy is often all that is appropriate. Immunotherapy has a small treatment role at present.

Kaposi's sarcoma in a homosexual--10 years on.

Kaposi's sarcoma is seen in one of several clinical settings. Before the recognition of the acquired immune deficiency syndrome (AIDS) in the early 1980s, the most frequent presentation of Kaposi's sarcoma in the UK was the so-called 'classical' form of the disease. The most common form of Kaposi's sarcoma in this country is now that associated with AIDS, which particularly affects young male homosexuals. Here we describe a homosexual man who has developed many Kaposi's sarcoma tumours during the past 10 years. The disease has run a benign course and there is no evidence of infection with human immunodeficiency virus (HIV).

Angiosarcoma of the face and scalp, prognosis and treatment.

72 patients with angiosarcoma (AS) of the face and scalp have been analyzed with respect of various prognostic factors and the effects of different treatment regimes. This disease predominantly occurs in the elderly (age range, 56-92 years), and affects men rather more frequently than women (men: 44, women: 28). The clinical presentation varied, and included bruise-like lesions, dusky plaques, chronic edema or cellulitis, ulcerated nodules, pyoderma, and infected conditions. Due to lack of clinical awareness and problems with histologic assessment, delays in diagnosis were frequent. The majority of the tumors arose in the upper part of the face or scalp. Less commonly, the central part of the face was affected while only three tumors developed in the mandibular region. Overall the prognosis was poor; one half of the patients died within 15 months of presentation. Only 12% of the patients survived 5 years or more. Patients with lesions that were less than 10 cm in diameter responded better to treatment and statistically survived longer than those with larger lesions, emphasizing the crucial importance of early diagnosis. There is some indication that men, younger patients, patients with lesions on the central part of the face survived longer, but this was not of statistical significance. The histologic differentiation of the tumors at presentation also was of doubtful prognostic significance. Despite the overall poor prognosis, radical radiotherapy (mostly wide-field electron-beam therapy) in seven patients resulted in the apparent eradication of the local skin disease and prolonged survival of the patients. Pulmonary metastases developed 10 years later in two of those patients, however, but the face and scalp remained tumor-free.
