Adjuvant chemotherapy with cyclophosphamide or CMF in premenopausal women with stage II breast cancer

Summary After total mastectomy and partial axillary dissection, 805 premenopausal women with stage II breast cancer were randomized to receive postoperative radiotherapy (RT) alone, RT + cyclophosphamide (C) for 12 monthly cycles, or RT + cyclophosphamide/methotrexate/5-fluorouracil (CMF) for 12 monthly cycles. At 3 years actuarial relapse-free survival for RT + C and RT + CMF was significantly better than for RT alone (p = 0.0009 and 0.0001, respectively). There was no significant difference in relapse-free survival between RT + C and RT + CMF.C resulted in more pronounced haematologic toxicity and a higher frequency of amenorrhoea and of alopecia than CMF, while CMF resulted in more pronounced nausea and stomatitis than C.In the preliminary results, C alone may be as effective as CMF in prolonging relapse-free survival in premenopausal women with stage II breast cancer.     

Menopausal hot flushes after breast cancer

The study aimed to improve understanding of the natural history and impact of hot flushes after breast cancer. Data were collected from women participating in an RCT of relaxation to reduce the incidence of flushes from breast cancer follow-up clinics from two hospitals in South-East England. Repondents were 150 women experiencing hot flushes following completion of primary treatment for breast cancer. This study utilized a flush diary, the Hot Flushes and Night Sweats Questionnaire (HFNSQ), Functional Assessment of Cancer Therapy with Endocrine Subscale (FACT-ES) and Spielberger State/Trait Anxiety Index (STAI) as the main outcome measures. The study found that in this sample, 51 (34%) women experienced flushes more than five years after diagnosis and 75 (50%) more than 5 years after menopause. Sleep disruption occurred in 90 women (72% of those that returned diaries), affecting half of the nights they recorded. The mean problem rating on the HFNSQ was 4.85 out of 10. A peak incidence of flushes was apparent around 10 a.m. in women taking tamoxifen. It was concluded that hot flushes after breast cancer may be long-lasting and cause sleeping difficulties for many women. Tamoxifen may affect the diurnal pattern of flushes. After breast cancer, the duration of flushes, potential distress and disruption to women's lives should not be underestimated and appropriate interventions should be offered.     

The occurrence of symptoms of possibly chronic airway diseases in toddlers

323 toddlers were examined by a group of G.P.'s who used a modified Medical Research Council questionnaire on respiratory symptoms. In 26.3% of these children one or more of the following symptoms were found on examination: chronic cough, “full chest”, wheezing or whistling, shortness of breath, asthma, or rhonchi. By and large, the frequency of symptoms is in accordance with the results of other investigators who examined older children. There was a higher percentage of symptomatic boys than girls. The difference was almost statistically significant and agreed with the sparse data in the literature. For the sake of comparison, 80 originally symptom-free toddlers were randomly selected and the children of both groups were examined by physicians 3 times a year over a 3- to 4-year period (a total of 944 examinations). In a double-blind trial, the symptomatic children were given a syrup of either phenergan/promethazine or a placebo. During this time they were visited twice a month by a nurse who questioned each mother as to the frequency of the symptoms in their children. A total of 1247 such house visits were carried out. A statistically significant decrease of some symptoms could be found in the “phenergan children”.     

Prednisolone withdrawal therapy enhances the effect of human lymphoblastoid interferon in chronic hepatitis B

Background/Aims: The aim of this multicentre, randomised, controlled, clinical trial was to evaluate the effect of prednisolone followed by lymphoblastoid interferon treatment in chronic hepatitis B.Methods: Two hundred and thirteen patients with chronic hepatitis B were randomised to either prednisolone (2 weeks of 0.6 mg/kg/day, 1 week of 0.45 mg/kg/day and 1 week of 0.25 mg/kg/day) or matching placebo followed by a 2-week rest phase and then human lymphoblastoid interferon 10 MU daily for 5 days followed by 10 MU thrice weekly for 11 weeks. Of 200 evaluable patients, 33 (16.5%) were females, and 50 (25%) were male homosexuals. Thirty three patients (16.5%) had chronic persistent hepatitis, 145 (72.5%) had chronic active hepatitis and 22 (11%) had active cirrhosis.Results: Survival analysis disclosed statistically significant effects of prednisolone pre-treatment on both HBeAg disappearance and HBeAg to anti-HBe seroconversion (log-rank test statistics 5.43; p=0.02 and 4.75; p=0.03). Observed HBeAg disappearance and HBeAg to anti-HBe seroconversion rates (placebo vs. prednisolone patients) were 28% vs. 44% and 23% vs. 38%. Six months after stopping interferon, HBV DNA was negative in 51% of prednisolone patients vs. 28% of placebo patients (Chi-square test statistic 6.13; p=0.013). Prednisolone pre-treatment tended to be more effective in patients with higher transaminase levels and in patients with low levels of HBV DNA. Fifteen patients (7.5%) (13 within 1 year of follow-up) eventually lost HBsAg; 14 of these subsequently developed anti-HBs. Interferon treatment was modified in 102 patients (51%). Three out of 22 patients with cirrhosis (14%), one of whom received prednisolone pre-treatment, developed hepatic decompensation with a fatal outcome while on interferon treatment.Conclusions: Prednisolone pre-treatment significantly enhanced the treatment effect of lymphoblastoid interferon in terms of HBeAg clearance and seroconversion to anti-HBe. Treatment should be used with caution in patients with cirrhosis and avoided in patients showing signs, or with a history, of decompensated cirrhosis.
