Oral clodronate and reduction in loss of bone mineral density in women with operable primary breast cancer.

BACKGROUND: Women with primary breast cancer who receive systemic therapy may experience ovarian failure or early menopause, leading to a loss of bone mineral density (BMD). Loss of BMD may be reduced by use of bisphosphonates, compounds that inhibit the action of osteoclasts (cells that absorb or remove bone tissue). We have conducted a double-blind, randomized, two-center trial to evaluate BMD in women with primary breast cancer who were given the bisphosphonate clodronate (1600 mg/day orally) or placebo for 2 years. METHODS: From August 31, 1990, through March 31, 1996, more than 300 eligible patients had been accrued, randomly assigned to study treatment, given the appropriate primary surgical care and systemic (chemotherapy and/or tamoxifen) therapy, and had completed follow-up for at least 1 year. BMD in the lumbar spine and in the hip, including the trochanteric area, was measured by use of dual-energy x-ray absorptiometry at the beginning of treatment and after 1 and 2 years of treatment. Changes in BMD were calculated as percent changes from the initial readings. Treatment effects for clodronate versus placebo (i.e., mean percent changes in BMD with clodronate minus mean percent changes in BMD with placebo) at 1 and 2 years for individual sites were calculated. RESULTS: After 1 year, the treatment effects for clodronate versus placebo in the lumbar spine, the total hip, and the trochanter, respectively, were as follows: +2.38% (95% confidence interval [CI] = 1.36-3.41), +0.74% (95% CI = -0.13 - 1.60), and +1.29% (95% CI = 0.24-2.34). After 2 years, the corresponding treatment effects were +1.72% (95% CI = 0.12-3.34), +1.85% (95% CI = 0.51-3.20), and +2.30% (95% CI = 0.66-3.94), respectively. CONCLUSIONS: Oral clodronate appears to reduce the loss of BMD in patients who receive treatment for primary breast cancer.

Short intensive primary chemotherapy and radiotherapy in sporadic primary CNS lymphoma (PCL).

PURPOSE: To assess the efficacy and toxicity of combined modality therapy with short intensive primary chemotherapy in the treatment of primary CNS lymphoma (PCL). METHODS AND MATERIALS: Prospective study of 31 nonimmunodeficient patients with PCL treated with initial chemotherapy (13 shortened MACOP-B; and 18 modified MACOP with high dose methotrexate) followed by radiotherapy (whole brain and a boost). Patients were aged 18-72 years (median 51 years). Eight patients had positive CSF cytology of which one had spinal meningeal disease; one patient had vitreous involvement. RESULTS: The overall complete response (CR) rate after chemotherapy and radiotherapy was 69% (95% Confidence Interval: 49-84%). At a median follow-up of 24 months (4 months to 10 years) median survival was 23 months and 5-year survival 34%. Age, sex, performance status, number of lesions, CSF cytology, and extent of surgery were not of prognostic significance for survival on univariate analysis. Eleven patients developed mucositis (Grade 3+) and 21 hematological toxicity (Grade 3+) with 22 septicemic episodes in 15 patients. Three patients developed dementia, one assumed to be treatment related, and two due to recurrent disease. CONCLUSION: The survival results of short intensive primary chemotherapy followed by radiotherapy are similar to the results of chemotherapy in Stage IV aggressive systemic non-Hodgkin's lymphoma, although the treatment was associated with high morbidity. The apparently favorable results when compared to radiotherapy alone may at least in part be due to selection of patients with good prognostic factors. To confirm the benefit of combined chemotherapy and radiotherapy over either of the two modalities alone requires evaluation in large prospective and ideally randomized studies.

Haematological toxicity of cranio-spinal irradiation.

BACKGROUND: To assess the frequency and severity of myelosuppression due to cranio-spinal irradiation either alone or in combination with chemotherapy and to identify patients at high risk of haematological toxicity who may require supportive therapy. MATERIALS AND METHODS: Between 1965 and 1994, 210 patients received cranio-spinal axis (CSA) radiotherapy as a component of treatment for primary CNS tumours at the Royal Marsden Hospital. Full blood counts (FBC) were obtained before, during and after radiotherapy in 200 patients. Haematological toxicity was graded according to the WHO criteria and duration was measured from the onset of grades 3 and 4 toxicity until recovery to grade 2. RESULTS: Sixty-six (33%) patients developed grades 3 and 4 haematological toxicity. Nadir occurred during radiotherapy and was most frequent during the second week of spinal radiotherapy. Low haemoglobin and white cell counts prior to radiotherapy increased the likelihood of myelosuppression. Nine patients had febrile episodes requiring antibiotic therapy. Treatment was interrupted in 49 patients but treatment time was extended beyond 12 weeks in only 17 (8%) patients of which nine were due to haematological toxicity. Chemotherapy (vincristine) during radiotherapy did not impact on haematological toxicity. Age and prior chemotherapy were independent predictive factors for haematological toxicity. The relative risk of leukopaenia in children compared to adults was 7.9 (95% CI 3.4-18.6%). Patients who received prior chemotherapy had a relative risk of toxicity of 6.1 (95% CI 2.9-12.8%). CONCLUSION: One-third of patients undergoing CSA radiotherapy develop grades 3 and 4 haematological toxicity. The risk is higher in children and in patients who receive chemotherapy prior to radiation. There was no treatment-related mortality and only nine of 200 patients (9/60 of those with toxicity) required supportive treatment for neutropaenic sepsis. The low incidence severe haematological toxicity does not warrant routine use of haemopoietic growth factors during CSA irradiation and future studies should target high risk subgroups.

A limited role for VEEP (vincristine, etoposide, epirubicin, prednisolone) chemotherapy in childhood Hodgkin's disease.

The VEEP regimen (vincristine, etoposide, epirubicin, prednisolone), with or without involved field radiotherapy, has been shown to be an effective treatment in adult Hodgkin's disease. In an attempt to avoid the late sequelae of both alkylating agents and radiotherapy this regimen has been studied in a series of 54 children and young adults. Early analysis suggested that the relapse rate was higher with VEEP than with standard alkylating agent-based regimens. Sufficient follow-up has now been achieved to evaluate the likelihood of sustained remission following second-line treatment and therefore the overall long term survival with this treatment approach. The 5-year Overall Survival (OS) and 5-year Progression Free Survival (PFS) for patients with stage I-III disease was 93% and 82% respectively. However, the 5-year OS and PFS for stage IV patients was only 44% and 50%, respectively. Of 13 patients who were initial treatment failures on VEEP, 7 of whom had advanced disease, only 6 were salvaged with second-line therapy. 8 of 33 who attained a complete response (CR) relapsed and there were 2 relapses in those achieving a partial response (PR) (n = 8). All those relapsing from CR/PR were salvaged by second-line alkylating agent chemotherapy +/- radiotherapy, +/- high dose chemotherapy. In conclusion, patients with stage I-IIIA, non-bulky disease, the moderately high relapse rate did not adversely affect the overall high cure rate, although VEEP failures were subjected to a high total treatment burden. VEEP alone is inadequate in patients with stage IV disease, bulky mediastinal disease in/or those with B symptoms in whom there is a high primary failure rate and relatively poor results with second line therapy.

Changes in hormone receptors and proliferation markers in tamoxifen treated breast cancer patients and the relationship with response.

AIM: To determine the effects of tamoxifen on the levels of hormone receptors and proliferation markers in the early phase of treatment and the relationship of the changes with tumor response in patients with primary breast cancer. METHODS: Twenty-one women with primary, operable breast carcinomas were treated with tamoxifen 20 mg daily. Fine needle aspiration (FNA) was used to obtain samples prior to the start and at 14 days and 8-weeks post-treatment. From these samples estrogen receptor (ER), progesterone receptor (PgR), and Ki67 levels were determined using immunocytochemistry and ploidy and S-phase fraction (SPF) using flow cytometry. Tumor response was measured clinically according to UICC criteria. RESULTS: There were 12 responders (2 CR, 10 PR) and 9 non-responders (2 NC, 7 PD). Responders were more likely to be ER+ (p = 0.002), PgR+ (p = 0.006), and low SPF (p = 0.06). At 14 days post-tamoxifen, the median decrease in Ki67 (% cells staining) for responders was -4.8 and for non-responders -0.15 (p = 0.005). This decrease was seen predominantly in ER+ tumours. The difference in SPF was not significant. A decrease in ER was seen in 3/15 patients all of whom were responders. A rise in PgR was seen in 7/17 patients and all but one were responders. Similar changes for ER and PgR were seen at 8-weeks post-tamoxifen, although the reductions in Ki67 and SPF at that time point were not related to response. CONCLUSION: We have observed a decrease in Ki67 and ER and a rise in PgR after 14 days of treatment with tamoxifen that was related to subsequent response. This is the first study in which an early decrease in a proliferation marker has been shown to relate to subsequent clinical response.

Good symptom relief with palliative MVP (mitomycin-C, vinblastine and cisplatin) chemotherapy in malignant mesothelioma.

PURPOSE: To evaluate the therapeutic impact of a simple combination chemotherapy regimen on symptoms related to malignant mesothelioma. MATERIALS AND METHODS: Between October 1986 and June 1997, 39 patients with advanced inoperable malignant mesothelioma were treated with palliative MVP (mitomycin-C 8 mg/m2 q. six weeks, vinblastine 6 mg/m2 q. three weeks and cisplatin 50 mg/m2 q. three weeks) chemotherapy and assessed for objective response and relief of symptoms. RESULTS: Eight of 39 patients (20%) achieved an objective partial response with a median duration of nine months: only five patients had progression of disease during chemotherapy. Twenty-four of 39 (62%) had an overall improvement in their symptomology with particularly good responses for pain (79%). These benefits were independent of performance status. Resolution of symptoms was achieved in all responding patients within two treatment cycles. There was no statistically significant difference in duration and incidence of symptom response in those patients achieving radiological PR compared with those with no change and more than 60% of patients with radiological no change obtained useful symptom control. The treatment was well tolerated with only four patients developing grade 3 leucopenia and three with grade 3 nausea. CONCLUSIONS: MVP is a well tolerated regimen and its use in malignant mesothelioma provides useful symptomatic benefit. These results should be the basis for further trials of MVP in the management of mesothelioma with symptom control as a principal endpoint.

A pilot study of MVP (mitomycin-C, vinblastine and cisplatin) chemotherapy in small-cell lung cancer.

MVP chemotherapy (mitomycin C 8 mg m(-2), courses 1, 2, 4 and 6, vinblastine 6 mg m(-2), cisplatin 50 mg m(-2)) is an active low-toxicity regimen in non-small-cell lung cancer (NSCLC). Based on the single-agent activity of these agents in SCLC, we have conducted a phase II trial of MVP in SCLC. Fifty chemo-naive patients with SCLC were entered in this trial. There were 33 men and 17 women with median age 66 years (range 46-83 years); 18 patients had limited disease (LD) and 32 extensive disease (ED). WHO performance status (PS) was: three patients PS 0, 33 patients PS 1, ten patients PS 2, four patients PS 3. A maximum of six cycles was given in responding patients. On completion of chemotherapy, patients with LD obtaining complete response (CR)/good partial response (PR) received thoracic irradiation and those obtaining CR were offered entry into the ongoing MRC Prophylactic Cranial Irradiation Trial. The overall response was 79% with 17% CR and 62% PR. For LD patients, 38% obtained CR but for ED only one patient achieved CR. Median response duration for LD patients was 8 months and for ED patients 5 months. Median survival was 10 months for LD patients and 6 months for ED patients. There was complete resolution of symptoms in 24%, partial improvement in 68%, no change in 2% and progressive symptoms in 6%. As regards toxicity, 24% developed WHO grade 3/4 neutropenia, 16% grade 3/4 thrombocytopenia and 6% significant hair loss. Two patients died during the first week of treatment with neutropenic infection. Quality of life using the EORTC questionnaire (QLC-C30) with lung cancer module demonstrated significant improvements from baseline levels in emotional and cognitive functioning, global QOL, of pain, dyspnoea and cough. MVP, an effective palliative regimen for NSCLC, is also active against SCLC with low toxicity and merits comparison with more toxic conventional schedules.

Improved cure rate in children with B-cell acute lymphoblastic leukaemia (B-ALL) and stage IV B-cell non-Hodgkin's lymphoma (B-NHL)--results of the UKCCSG 9003 protocol.

From June 1990 to February 1996, 35 patients with B-cell acute lymphoblastic leukaemia (B-ALL) 13 of whom had CNS disease and 28 patients with stage IV B-cell non-Hodgkin's lymphoma (B-NHL) 22 of whom had CNS involvement were treated with a short, intensive multiagent chemotherapy regimen (UKCCSG 9003 protocol) based on the French LMB 86 regimen. Fifty-five were boys. The age range was 11 months to 16.5 years (median 8.4 years). Chemotherapy included cyclophosphamide, vincristine, daunorubicin, high-dose methotrexate (COPADM) and etoposide/high-dose cytarabine (CYVE) with frequent intrathecal (i.t.) triple therapy (methotrexate, cytarabine and hydrocortisone). Cranial irradiation (24 Gy in 15 fractions) was recommended in patients with overt CNS disease. One patient with Wiskott-Aldrich syndrome was withdrawn after entry and has been excluded from the analysis. Ten patients (16%) have relapsed (CNS, four; BM, two; combined CNS and BM, three; and jaw, one) 4-11 months after diagnosis and two patients never achieved complete remission (CR). All have died. In seven of the patients who relapsed, treatment had been modified or delayed because of poor clinical condition. Seven patients (11%) died of toxicity 11 days to 4 months after diagnosis. The cause of death was sepsis (n = 5) or sepsis with renal failure (n = 2). With a median follow-up of 3.1 years from diagnosis (range 9 months to 6.3 years), 43 patients (69%) survive in CR. This study confirms the effectiveness of this regimen with regard to the relapse rate (16%), although the rate of toxic death is of concern.

Clinical benefit from palliative chemotherapy in non-small-cell lung cancer extends to the elderly and those with poor prognostic factors.

The intention of this study was to identify the pretreatment characteristics predicting for the survival, objective response and symptom relief in patients with non-resectable, non-small-cell lung cancer (NSCLC) managed in the Lung Unit at the Royal Marsden Hospital. This analysis included 290 patients with advanced NSCLC generally treated with a cisplatin-based chemotherapy regimen in one of a series of trials. Thirty-seven pretreatment variables, response and survival data were collected prospectively and analysed using univariate and multivariate methods. By multivariate analysis performance status, disease extent and pattern of metastases along with certain biochemical features were influential independent variables for survival, objective and symptom response. Older age was positively associated with objective response (P = 0.04). When the independent factors for symptom response were used to group patients into prognostic categories, 30-48% of patients with an adverse set of factors had symptom relief. Similarly using the relative risk of death to subgroup the patient population, 54% of patients at high risk of death (greater than 8.0), with a median survival of 2.5 months, had symptom relief. The data are consistent with other studies in identifying the pretreatment factors predicting for survival and objective response. Additionally, older age is positively associated with objective response and the majority of patients with the worst prognosis have symptom relief from treatment with chemotherapy.

The effects of norethisterone on endometrial abnormalities identified by transvaginal ultrasound screening of healthy post-menopausal women on tamoxifen or placebo.

Tamoxifen (tam) is used extensively for treatment of patients with breast cancer and is being evaluated for chemoprevention in healthy women. It has, however, been reported to increase the risk of endometrial cancer in post-menopausal women, probably by an oestrogenic effect on the endometrium. It also causes endometrial cysts and polyps. The aims of this study were to identify the incidence of endometrial thickening, polyps and cysts by transvaginal ultrasound (TVUS) screening of a population of post-menopausal healthy women in the Royal Marsden tamoxifen chemoprevention trial and to evaluate the possible benefit from the use of intermittent norethisterone (NE) in women with persistent changes. Since 1990, we have undertaken regular TVUS, using an endovaginal B mode probe, of the 463 post-menopausal women in the trial randomized to tam (20 mg day(-1)) or placebo (plac), without breaking the randomization code. Endometrial thickening (ET) was defined as > or = 8 mm at the widest point across the myometrial cavity in the longitudinal plane, including any stromal changes. Cystic changes were defined as more than one hypoechogenic area > 1 mm. Polyps were identified using saline hydrosonography. Oral NE (2.5 mg day(-1)) was used for 21 days out of 28 for three consecutive cycles by women with persistent endometrium > or = 8 mm, including cystic and polypoid changes. TVUS was repeated after the three courses to evaluate any change caused by NE and endometrial biopsies, including hysteroscopy, was performed on those women with persistent abnormalities. A persistent ET > or = 8 mm was identified in 56 (24%) of the 235 women on tamoxifen compared with only 5 (2%) of 228 women on placebo (P <0.0005). Stromal changes, including cysts, were detected in 36 (15%) and polyps in 26 (11%) of the women on tamoxifen compared with only two (< 1%) of the women on placebo (P << 0.0005). After 3 months of cyclical norethisterone, 39 of 47 women (83%) on tamoxifen had persistent ultrasound changes. However, 45 (96%) had a progesterone withdrawal bleed. Hysteroscopy was performed in 39 women on tamoxifen (28 endometrial biopsy, 15 polypectomy), five of whom had histological evidence of a proliferative endometrium and a further three had an atypical hyperplastic endometrium (one of whom had a focus of invasive carcinoma). The cysts and polyps which were detected in women on tam could not be reversed by NE and were presumably stromal and not of malignant risk. However, 96% of the women had withdrawal NE bleeding, indicating an oestrogenically primed endometrium which could be a mechanism for an increased risk of endometrial cancer. Further studies are required to ascertain whether a progestin would protect against this risk. As in other studies, these results indicate that any increased risk of endometrial cancer caused by tamoxifen is low, and that TVUS screening is probably not justified for asymptomatic women on tamoxifen.

Family history of breast cancer: what do women understand and recall about their genetic risk?

The current study has two aims: (1) to look at people's recall of risk information after genetic counselling and (2) to determine the impact of receiving an audiotape of the genetic consultation on level of recall, cancer related worry, and women's uptake of risk management methods. Using a prospective randomised controlled design, subjects receiving an audiotape were compared with a standard consultation group. Participants were drawn from attenders at the genetic clinics of two London hospitals and included 115 women with a family history of breast cancer. Assessment of perceived genetic risk, mental health, cancer worry, and health behaviour was made before counselling at the clinic (baseline) and by postal follow up. Usefulness of audiotapes and satisfaction with the clinical service was assessed by study specific measures. The data indicate that cancer worry is reduced by provision of an audiotape of the genetic consultation. Recall of the genetic risk figure, however, is not affected by provision of an audiotape and neither is it related to women's overall perception of being more or less at risk of breast cancer than the average woman. Forty-one percent of women accurately recalled their personal risk of breast cancer at one month follow up; however, 25% overestimated, 11% underestimated, and 23% could not remember or did not know their breast cancer risk. Recall of the risk figure is more accurate when the clinical geneticist has given this to the woman as an odds ratio rather than in other formats. Subsequent health behaviour is unaffected by whether women have an audiotape record of their genetic consultation. Results suggest that having a precise risk figure may be less important than women taking away from the consultation an impression that something can be offered to help them manage that risk. Provision of an audiotape of the consultation is of limited usefulness. The need for psychological care to be better integrated into genetic counselling at cancer family clinics was highlighted by the study. The results are discussed in terms of future service development.

Clinical prognostic and predictive factors for primary chemotherapy in operable breast cancer.

PURPOSE: This study aimed to identify clinical factors that are of prognostic significance or that predict for subsequent treatment outcome in patients with large operable breast cancer treated with primary chemotherapy (PCT) at our institution. METHODS: One hundred eighty-five patients received the following regimens: CMF or MMM (76 patients), ECF (75 patients), AC or FEC (34 patients), followed by surgery, with radiotherapy (RT) given to those with breast conservation. A number of common clinical variables were assessed in relation to local recurrence-free survival (LRFS), disease-free survival (DFS), and overall survival (OS). RESULTS: Clinical responders had improved DFS (P = .009) and OS (P = .08) compared with nonresponders. There was no association between clinical or pathologic complete remission (CR) and survival. Pretreatment clinical axillary node positivity was a significant predictor of worsened DFS (P = .0001), OS (P = .0001), and LRFS (P = .03). Patients remaining clinically node-positive postchemotherapy had an inferior outcome compared with those becoming node-negative (DFS, P = .03; OS, P = .03) but pathologic axillary node status was not shown to predict for survival. Twenty-nine patients in clinical CR following PCT who electively did not have surgery and were treated with RT alone had significantly increased local recurrence rate compared with partial responders having surgery and RT (P = .02). There were no differences in DFS or OS between these groups. On multivariate analysis, clinical axillary node status was the only independent predictor of OS and DFS, and LRFS. CONCLUSION: Pretreatment and posttreatment clinical axillary node status is a major predictor of outcome following PCT. Complete clinical response does not define a more favorable subgroup compared with those not obtaining CR.

Randomized phase II trial of infusional fluorouracil, epirubicin, and cyclophosphamide versus infusional fluorouracil, epirubicin, and cisplatin in patients with advanced breast cancer.

PURPOSE: We previously developed an inpatient regimen that consisted of infusional fluorouracil (5-FU), epirubicin, and cisplatin (ECisF), with a response rate of 86% in advanced breast cancer. The current phase II 2:1 randomized study investigated whether cyclophosphamide can be substituted for cisplatin (ECycloF) to reduce toxicity and allow the regimen to be administered on an outpatient basis without loss of efficacy. PATIENTS AND METHODS: Ninety-six women (median age, 49 years; range, 28 to 73) with breast cancer (59 metastatic, 37 locally advanced) received continuous infusional 5-FU (200 mg/m2/d via Hickman line) and six cycles of epirubicin (60 mg/m2 every 21 days) with either cyclophosphamide 600 mg/m2 every 21 days (38 metastatic, 24 locally advanced) or cisplatin 60 mg/m2 every 21 days (21 metastatic, 13 locally advanced). There were no significant differences in patient characteristics between these groups. RESULTS: ECycloF was better tolerated than ECisF in terms of lethargy (P = .005), stomatitis (P = .008), plantar palmar erythema (P = .02), constipation (P < .001), thrombosis (P = .0014), and nausea and vomiting (P = .05). Although there was a trend toward more anemia and leukopenia with ECisF (P =. 1), there was no significant difference in the rates of infection. Efficacy was comparable in terms of overall response (69% v 68%), complete response (CR; 13% v 15%), and median progression-free survival (9 v 8 months). CONCLUSION: ECycloF is an outpatient regimen with a lower incidence of severe nonhematologic toxicity than inpatient ECisF; it has comparable efficacy and is considerably more economical.

Safety of completion thyroidectomy for multicentric carcinoma.

The role of completion thyroidectomy after lobectomy for well-differentiated thyroid carcinoma remains controversial. The purpose of the present study is to compare the relative safety of a one-stage versus a two-stage approach in the management of thyroid cancer. Thirty consecutive patients with thyroid carcinoma were studied. In 14 patients, frozen-section diagnosis of carcinoma allowed total thyroidectomy at the initial operation. In 16 patients, carcinoma was found only on permanent section; thus, completion thyroidectomy was undertaken as a second stage. Transient hypocalcemia occurred in one patient in each group (one-stage, 7%; two-stage, 6%). There was one unilateral recurrent nerve paresis in the one-stage group and none in the two-stage group. We conclude that a two-stage procedure is a safe and effective approach for the treatment of thyroid cancer and can be employed in those instances in which the diagnosis of malignancy is insecure at the initial operation.

Craniopharyngioma: improving outcome by early recognition and treatment of acute complications.

PURPOSE: To assess the frequency, mode of presentation, treatment, and outcome of acute complications in patients with craniopharyngioma around the time of radiotherapy. METHODS AND MATERIALS: A review was made of 188 patients with craniopharyngioma treated with conservative surgery and external beam radiotherapy at the Royal Marsden Hospital between 1950 and 1992. RESULTS: Twenty six (14%) (95% confidence interval: 9-19%) patients with craniopharyngioma developed acute deterioration immediately before, during and 2 months after radiotherapy with visual deterioration (19 patients), hydrocephalus (7 patients), and global deficit (7 patients). Cystic enlargement with or without hydrocephalus was the most common cause of deterioration. No patient or disease characteristics were predictive of deterioration on univariate or multivariate analysis. Eighteen patients had surgical intervention at the time of deterioration and survived the immediate period. Six of seven patients who did not have surgical intervention died. All patients who survived the postcomplication period completed the full course of external beam radiotherapy. The 10-year progression-free survival of 162 patients without deterioration was 86%, and of 18 patients with acute deterioration who recovered after surgery, 77%. CONCLUSION: Patients with craniopharyngioma develop acute deterioration around the time of radiotherapy owing to cystic enlargement and/or hydrocephalus which does not represent tumor progression. Early recognition and appropriate surgical treatment followed by conventional full-dose radiotherapy are associated with good long-term outcome.

Survival analysis of patients with clinical stages I or II Hodgkin's disease who have relapsed after initial treatment with radiotherapy alone.

To aid treatment choice in early stage of Hodgkin's disease, we analysed patients registered in the IDHD Database with clinical stages I or II Hodgkin's disease who were not staged with laparotomy and whose initial treatment was with radiotherapy alone. The factors analysed for outcome after first relapse included initial stage, age, sex, histology, number of involved areas, mediastinal involvement, E-lesions, B-symptoms, erythrocyte sedimentation rate, alkaline phosphatase, serum albumin and haemoglobin. As well as presentation variables, we analysed the disease-free interval after initial radiotherapy and the extent of disease at relapse. A total of 1364 patients with clinical stage I or II Hodgkin's disease were treated with initial radiotherapy, of whom 473 relapsed. The probability of survival 10 years after relapse was 63%. For cause-specific survival (CSS), both multivariate and univariate analysis identified the importance of age at presentation and histological subtypes. When all causes of death were considered, the multivariate analysis identified age as the only significant factor. The length of initial disease-free interval had no influence on prognosis after relapse, but the 169 patients with nodal relapse had a higher cause-specific survival than those with an extranodal component of relapse (74% versus 51% at 10 years, P < 0.005). Thus, the important factors for outcome after initial treatment with radiotherapy are those factors predicting the risk of relapse after initial treatment together with those predicting outcome after relapse, namely age, histologic subtype and extent of disease at relapse.

A randomised trial of six versus twelve courses of chemotherapy in metastatic carcinoma of the breast.

Chemotherapy given to patients with metastatic carcinoma of the breast is palliative in intent. Longer regimens would be justified if there was a proven prolongation of symptom response or survival. We conducted a randomised trial to assess the survival of patients receiving up to six extra courses of chemotherapy compared with our conventional regimen of six courses. The patients received either VAC, VEC (vincristine, doxorubicin or epirubicin and cyclophosphamide) or MMM (mitozantrone, methotrexate and mitomycin C) therapy. Patients who had stable disease or were responding after six courses of chemotherapy were randomised to either stop or continue treatment for another six courses. Those patients receiving maintenance therapy had a significantly longer duration of response (P < 0.02) and a significantly longer progression-free survival (P < 0.01). However, there was no survival difference between the two groups. Furthermore, treatment toxicity, which was similar in the two groups, persisted for longer in the maintenance group. These results indicate no clinical advantage for giving maintenance chemotherapy in order to prolong survival of patients with metastatic breast cancer.
