Effectiveness of preoperative chemotherapy in the treatment of Wilms tumor with vena caval and intracardiac extension.
Surgical treatment of Wilms tumor with vena caval and intracardiac extension is challenging, often requiring cardiopulmonary bypass. We report the response to preoperative chemotherapy in 3 patients following a protocol at our hospital. The tumor thrombus was limited to the inferior vena cava in 2 patients and extended to the right atrium in 1. All 3 patients had marked reduction or complete eradication of the venous thrombus, facilitating the final surgical procedure. The patients are disease-free 18 months to 7 years after the initial treatment. Our protocol involves initial radiographic staging followed by needle biopsy, chemotherapy, repeat radiographic staging, definitive resection and additional chemotherapy. Our results confirm the effectiveness of this approach, which appears to decrease morbidity associated with intracaval and intra-atrial tumor extension.

Carcinoma of the maxillary antrum treated by pre-operative radiotherapy or radical radiotherapy alone.
The results of pre-operative radical radiotherapy and subsequent maxillary resection are reported in 54 consecutive patients with carcinoma of the maxillary antrum treated at The Royal London Hospital from 1965 to 1989. The actuarial two and five year survivals were 50.3 per cent and 38.5 per cent respectively. Patients with adenocarcinomas fared better when compared with squamous and undifferentiated carcinomas (log rank p = < 0.01). Undifferentiated carcinoma and involved regional lymph nodes were both very poor prognostic factors. In those patients who were either unfit for or refused maxillary resection, radical radiotherapy alone was still an effective treatment, with only a slight disadvantage in terms of local control and survival.

The use of a specific hypofractionated radiation therapy regimen versus classical fractionation in the treatment of breast cancer: a randomized study of 230 patients.
An ongoing randomized study of a specific regimen of hypofractionated radiation therapy (IHF) versus classical or standard radiation therapy (IC) for breast cancer was begun in the Department of Radiation Therapy of the Necker Hospital, Paris France, in January 1982. Breast cancer patients entered into this study received either IC to deliver 45 Gy in 25 fractions over 33 days or a specific IHF regimen to deliver 23 Gy in 4 fractions over 17 days. As of June 1989, 525 patients had been entered into the study. The first 230 patients treated from 1982 through December 1984 had a minimum follow-up of 4 years (range: 4 to 7 years). Preliminary analysis of the results in these first 230 patients are presented. The distribution of patients in this initial group according to clinical staging, associated treatments, and pathological nodes is as follows: T1 = 22%, T2 = 61%, T3 + T4 = 17%, palpable nodes = 28%, inflammatory signs = 7%, surgical treatment = 79% (mastectomy = 35%, tumorectomy + Ir.192 = 44%), radiation alone + neoadjuvant chemotherapy = 21%, N+ = 50% of patients undergoing surgery. Loco-regional recurrences developed in 7% (9/125) of patients in the IHF group and in 5% (5/105) of patients in the IC group. Complications were minor. The addition of the percentage of each complication noted results in a total of 23% for the IHF group and 19% for the IC group (one patient could present several complications). As we had previously observed when comparing these two fractionation regimens in other studies with other tumors, these preliminary results showed no evident difference in the effectiveness and rate of complications whether IHF or IC was used to treat patients with breast cancer.

A comparative immunogenicity-reactogenicity dose-response study of influenza vaccine.
This study examined the immunogenic and reactogenic responses of influenza vaccine in 29 healthy nonallergic adults at three vaccine dosages: 0.5 mL, 0.1 mL, and 0.05 mL. After immunization a 7-day assessment of adverse reactions was made and serial serum hemagglutination-inhibition (HAI) antibody responses were measured during a 28-day period. The incidence of adverse reactions was significantly decreased in the group receiving 0.1 mL and 0.05 mL compared with the group receiving 0.5 mL of vaccine. After immunization with 0.1 mL or 0.05 mL vaccine increases in serum HAI antibody to A/Leningrad, A/Taiwan, and B/Ann Arbor influenza antigens were seen comparable to those observed after 0.5 mL. However the magnitude of these rises were lower and were directly correlated with the dose of vaccine. Since immunization of egg-sensitive allergic patients with influenza vaccine poses a risk of localized and systemic reactions, a common clinical practice is to prevent such reactions by vaccine dilution. Although the results of the present study suggest that vaccine dilution results in a decrease in adverse reactions, there is also the risk of decrease protective immunity with this procedure and therefore the practice should not be condoned.

New lumps in the breast following conservation treatment for early breast cancer.
A new lump in the breast following conservation treatment for early breast cancer may represent a recurrence of the disease or may be a benign lesion. Clinical evaluation of these lumps is often extremely difficult and, potentially, mammography would seem to be of great importance in the assessment. Between November 1981 and March 1986, 214 patients with operable breast cancers of 4 cm or less in diameter underwent conservative treatment. The conservation technique comprised synchronous excision of the primary tumour without a wide margin, axillary clearance, interstitial irradiation with iridium 192 (2000 cGy), and subsequent external beam radiotherapy to the breast (4600 cGy). After an average follow-up of 26 months, 17 patients developed a new lump in the treated breast necessitating further biopsy. Seven of these were malignant and 10 benign. In the latter category the most frequent finding was fat necrosis. Clinically, the lesions were indistinguishable from each other. The mammographic signs, which best predicted malignancy, were either of a mass or of a malignant type of microcalcification. This study illustrates the problems associated with deciding the nature of a new lump in the breast following conservation treatment. Mammography is complementary to physical examination, and a base-line mammogram six months after completion of therapy is helpful. Despite the use of mammography, biopsy is the only definitive way of excluding recurrence.

Sensory changes after treatment of operable breast cancer.
A study has been conducted to compare the nature and severity of post-operative sensory changes (sensory loss, paraesthesiae, and pain) among patients with breast cancer treated by either modified radical mastectomy or a conservative procedure (tumourectomy, axillary clearance, iridium implant, and external radiotherapy). There was a similar incidence of post-operative sensory loss in the two groups, reported by 82% of the mastectomy group and 77% of the iridium group, and an equivalent rate of improvement (76 and 80% respectively). Post-operative paraesthesiae occurred in 61% of the mastectomy group and 63% of the iridium group; maximum severity of paraesthesiae was similar as was the percentage improving. Among the mastectomy group 55% reported phantom breast sensation and 61% of the iridium group had post-operative breast pain. Improvement occurred in 58% of those with breast pain. These findings may have implications for the counseling of patients with breast cancer who are going to be treated by certain conservative procedures.

Male factors in infertility--a preliminary report.
Findings in 325 consecutive primary seminal analysis done at the Infertility Treatment Centre of IPGMR, are discussed. The clinical profile of the infertile couples was recorded. Semen was examined for quantity, sperm density, motility and morphology. An attempt was also made to correlate past illnesses with the quality of semen. 65 patients (20%) showed azoospermia, while 29 (8.9%) showed sperm count of less than 10 million/ml. History of past illnesses which contribute to azoospermia/oligospermia was obtained in 46% of azoospermia cases compared to only 10% in subjects showing sperm count of over 10 million/ml. Commonest association between azoospermia and past illness was found in the case of small-pox, where out of 31 subjects with past history of small-pox, 15 showed complete azoospermia, one showed sperm density of less then 10 million/ml.
