Treatment implications of a positive sentinel lymph node biopsy for patients with early-stage breast carcinoma.

BACKGROUND: Sentinel lymph node (SLN) mapping and biopsy is emerging as an alternative to axillary lymph node dissection (ALND) in determining the lymph node status of patients with early-stage breast carcinoma. The hypothesis of the technique is that the SLN is the first lymph node in the regional lymphatic basin that drains the primary tumor. Non-SLN (NSLN) metastasis in the axilla is unlikely if the axillary SLN shows no tumor involvement, and, thus, further axillary interference may be avoided. However, the optimal treatment of the axilla in which an SLN metastasis is found requires ongoing evaluation. The objectives of this study were to evaluate the predictors for NSLN metastasis in the presence of a tumor-involved axillary SLN and to examine the treatment implications for patients with early-stage breast carcinoma. METHODS: Between June 1998 and May 2000, 167 patients participated in the pilot study of SLN mapping and biopsy at Westmead Hospital. SLNs were identified successfully and biopsied in 140 axillae. All study patients also underwent ALND. The incidence of NSLN metastasis in the 51 patients with a SLN metastasis was correlated with clinical and pathologic characteristics. RESULTS: Of 51 patients with a positive SLN, 24 patients (47%) had NSLN metastases. The primary tumor size was the only significant predictor for NSLN involvement. NSLN metastasis occurred in 25% of patients (95% confidence interval [95%CI], 10-47%) with a primary tumor size </= 20 mm and in 67% of patients (95%CI, 46-83%) with a primary tumor size > 20 mm (P = 0.005). The size of the SLN metastasis was not associated significantly with NSLN involvement. Three of 7 patients (43%) with an SLN micrometastasis (< 1 mm) had NSLN involvement compared with 38 of 44 patients (48%) with an SLN macrometastasis (> or = 1 mm). CONCLUSIONS: The current study did not identify a subgroup of SLN positive patients in whom the incidence of NSLN involvement was low enough to warrant no further axillary interference. At present, a full axillary dissection should be performed in patients with a positive SLN.

Probability of axillary node involvement in patients with tubular carcinoma of the breast.

BACKGROUND: The aim of this study was to investigate the frequency of axillary metastasis in women with tubular carcinoma (TC) of the breast. METHODS: Women who underwent axillary dissection for TC in the Western Sydney area (1984--1995) were identified retrospectively through a search of computerized records. A centralized pathology review was performed and tumours were classified as pure tubular (22) or mixed tubular (nine), on the basis of the invasive component containing 90 per cent or more, or 75--90 per cent tubule formation respectively. A Medline search of the literature was undertaken to compile a collective series (20 studies with a total of 680 patients) to address the frequency of nodal involvement in TC. A quantitative meta-analysis was used to combine the results of these studies. RESULTS: The overall frequency of nodal metastasis was five of 31 (16 per cent); one of 22 pure tubular and four of nine mixed tumours (P = 0.019). None of the tumours with a diameter of 10 mm or less (n = 16) had nodal metastasis compared with five of 15 larger tumours (P = 0.018). The meta-analysis of 680 women showed an overall frequency of nodal metastasis in TC of 13.8 (95 per cent confidence interval 9.3-18.3) per cent. The frequency of nodal involvement was 6.6 (1.7--11.4) per cent in pure TC (n = 244) and 25.0 (12.5--37.6) per cent in mixed TC (n = 149). CONCLUSION: A case may be made for observing the clinically negative axilla in women with a small TC (10 mm or less in diameter).

Estimating the benefits of adjuvant systemic therapy for women with early breast cancer.

BACKGROUND: Prognostic factors are commonly used to help identify women with node-negative breast cancer at high risk of recurrence. Although many are available, knowing which risk factor or combination of factors to use to estimate prognosis for an individual woman is often difficult. This study documented the baseline prognoses for a group of women with node-negative breast cancers, and estimated the potential benefits of adjuvant systemic therapy. METHODS: Ten-year, actuarial, cause-specific survival based on tumour size and histological grade using data from the Swedish Two-County Trial of mammographic screening was calculated for 1200 women with node-negative cancers of less than 30 mm diameter. The benefits of adjuvant systemic therapy for these women were then estimated using the published odds reductions in death from adjuvant systemic therapy from the Early Breast Cancer Trialists' Collaborative Group overview. RESULTS: The absolute 10-year survival benefits for subgroups of women based on tumour size and histological grade were estimated for women aged under 50 years by the addition of chemotherapy, and over 50 years by the addition of tamoxifen and/or chemotherapy. CONCLUSION: Decisions about adjuvant systemic therapy in women with node-negative breast cancer need to be individualized, taking into account treatment efficacy and toxicity. The quantitative methods presented in this paper facilitate such decisions.

Frequency and predictors of axillary lymph node metastases in invasive breast cancer.

BACKGROUND: The objectives of the present study were to evaluate the incidence and predictors of axillary lymph node metastases (ALNM) in patients with breast cancer, and to identify if axillary surgery could be safely omitted in selected patients. METHODS: Between January 1996 and May 2000, 492 patients underwent 501 axillary lymph node dissections (ALND). The incidence of ALNM was correlated with clinical and pathological characteristics by univariate and multivariate analyses. RESULTS: Axillary lymph node metastases were found in 41% (207/501) of cases. Univariate analysis showed that palpability of primary and axillary lymph node (ALN), pathological tumour size, grade, lymphovascular invasion (LVI) and multifocality or multicentricity were significant predictors of ALNM. By multivariate analysis, palpability of ALN, pathological tumour size, LVI and multifocality or multicentricity remained as independent predictors. Among the 431 cases without palpable ALN, no ALNM were found if the tumour was < or = 5 mm, non-multifocal or multicentric, and without LVI, or the tumour was a tubular or mucinous carcinoma < or = 15 mm (n = 21). The frequency of ALNM in the absence of the other risk factors was 11% (7/64) if the tumour size was > 5-10 mm, and 17% (19/113) if the tumour was > 10-20 mm. However, the incidence of ALNM was 72% for the 32 clinically node-negative cases with multifocal or multicentric tumour > or = 10 mm and LVI. Those patients with palpable ALN (n = 66) had a greater than 50% risk of ALNM. CONCLUSIONS: Routine ALND could be omitted in clinically node-negative patients with either a < or = 5-mm, LVI-negative tumour, or a < or = 15-mm tubular or mucinous carcinoma. Axillary lymph node dissection is still useful for determining pathological nodal status in all other cases, and in most cases with palpable ALN, as a therapeutic manoeuvre.

Treatment of the axilla in early breast cancer: past, present and future.

BACKGROUND: The optimal treatment of the axilla in early breast cancer is controversial. The present study reviews the pattern and predictors of regional recurrence (RR) and prognosis after RR in patients with early breast cancer treated by conservative surgery and radiotherapy (CS + RT). Implications of the results on current practice and future directions are explored. METHODS: Between 1979 and 1994, 1158 patients with stage I or II breast cancer were treated with CS + RT at Westmead Hospital. Two groups of patients were compared: 782 patients who underwent axillary dissection (axillary surgery group) and 229 patients who received radiotherapy (axillary RT group) as the only axillary treatment. At least 10 lymph nodes were dissected in 82% of the axillary surgery group. Of the women in the RT group, 90% received RT to the axilla and supraclavicular fossa (SCF) only and 10% also received RT to the internal mammary chain (IMC). RESULTS: With a median follow-up period of 79 months for the axillary surgery group and 111 months for the axillary RT group, 27 patients developed a RR (2.8% and 2.2%, respectively). Seven patients (0.9%) in the axillary surgery group and three patients (1.3%) in the axillary RT group developed a RR in the axilla (P, not significant). Of the patients with SCF recurrences, 14 (1.8%) were in the axillary surgery group and one (0.4%) in the axillary RT group (P, not significant). One patient in the axillary surgery group developed concurrent axillary and SCF recurrences, while a patient in the axillary RT group developed an IMC recurrence. Twenty (74%) of the 27 patients with a RR developed a concurrent or subsequent distant relapse (30% and 44%, respectively). In the pathologically node-positive patients, the axillary recurrence rate was higher in those who had less than five nodes removed (17%) than those who had 10 or more nodes removed (0%; P = 0.01). The SCF recurrence rate was higher in patients with four or more positive axillary nodes (9.5%) than in those with 0-3 positive nodes (1.5%; P = 0.003). CONCLUSION: Adequate treatment of the axilla by surgery or RT alone is associated with a low rate of RR. The incidence of distant relapse was substantial in patients who developed a RR, which gives emphasis to the importance of optimizing local-regional control.

Estimating risk of breast cancer from population incidence affected by widespread mammographic screening.

OBJECTIVES: To estimate the absolute risk of breast cancer in women, allowing for the effect on incidence of the introduction of widespread mammographic screening. DESIGN: Annual breast cancer incidences were compared with numbers of annual mammograms in the population for 1980-96 to identify periods most likely to be affected by screening. Age specific breast cancer incidences 1972-96 were modelled by Poisson regression with an age, period, and cohort analysis. The 1996 age specific incidence was recalculated with the stable period effect 1972-89, and the age and cohort effects. Age specific incidence was converted to cumulative risk of breast cancer to age 79. SETTING: Population based data from all women in New South Wales (NSW), Australia. PATIENTS OR PARTICIPANTS: Breast cancer incidence in women 1972-96 obtained from the NSW Central Cancer Registry and female populations derived from successive censuses. Mammographic data from private sector mammograms (1985-96), and the mammographic screening service (1988-96) for NSW women. INTERVENTIONS: Introduction of population mammographic screening. MAIN OUTCOME MEASURES: Recorded age specific incidence and absolute risk of breast cancer to age 79 was compared with underlying incidence and cumulative absolute risk, adjusted for recent period effects, most likely due to mammographic screening in the population. RESULTS: The age, period, and cohort model showed an increasing effect for birth cohorts 1910-44 then a plateau, and prominent period effects in 1991 and 1994-6. Increased incidence of breast cancer coincided with an increase in mammographic examinations in the private sector (1991), and prevalent rounds of mammographic screening in the population (1994-6) after introduction of a statewide mammographic screening service. Recorded incidence produced a breast cancer risk to age 79 of 9.9% (1 in 10) for 1996, whereas estimation of underlying incidence yielded a risk of 8.5% (1 in 12). CONCLUSIONS: The introduction of mammographic screening in a population inflates the incidence of breast cancer because of diagnosis of prevalent cases. For the purpose of public and clinical communication, it is more reasonable and responsible to adjust for period effects (due to screening) rather than produce risk estimates based on recorded incidence, which may show an alarming increase in risk of breast cancer over a short period.

Three-dimensional dose distribution of tangential breast irradiation: results of a multicentre phantom dosimetry study.

BACKGROUND AND PURPOSE: One aspect of good radiotherapeutic practice is to achieve dose homogeneity. Dose inhomogeneities occur with breast tangent irradiation, particularly in women with large breasts. MATERIALS AND METHODS: Ten Australian radiation oncology centres agreed to participate in this multicentre phantom dosimetry study. An Alderson radiation therapy anthropomorphic phantom with attachable breasts of two different cup sizes (B and DD) was used. The entire phantom was capable of having thermoluminescent dosimeters (TLD) material inserted at various locations. Nine TLD positions were distributed throughout the left breast phantom including the superior and inferior planes. The ten centres were asked to simulate, plan and treat (with a prescription of 100 cGy) the breast phantoms according to their standard practice. Point doses from resultant computer plans were calculated for each TLD position. Measured and calculated (planning computer) doses were compared. RESULTS: The dose planning predictability between departments did not appear to be significantly different for both the small and large breast phantoms. The median dose deviation (calculated dose minus measured dose) for all centres ranged from 2. 3 to 5.3 cGy on the central axis and from 2.1 to 7.5 cGy for the off-axis planes. The highest absolute dose was measured in the inferior plane of the large breast (128.7 cGy). The greatest dose inhomogeneity occurred in the small breast phantom volume (median range 93.2-105 cGy) compared with the large breast phantom volume (median range, 100.1-107.7 cGy). There was considerable variation in the use (or not) of wedges to obtain optimized dosimetry. No department used 3D compensators. CONCLUSION: The results highlight areas of potential improvement in the delivery of breast tangent radiotherapy. Despite reasonable dose predictability, the greatest dose deviation and highest measured doses occurred in the inferior aspects of both the small and large breast phantoms.

Quality of life three months and one year after first treatment for early stage breast cancer: influence of treatment and patient characteristics.

This paper reports the quality of life (QoL) of a large cohort of Australian women three and twelve months after surgery for early stage breast cancer (ESBC), and shows that the impact of disease and treatment on QoL differed by age, education and marital status. Eighty-three percent of eligible patients were recruited; 86% had breast conserving surgery and 14% mastectomy. Response rates were 93% (n = 305) at three months and 88% (n = 291) at one year. Quality of life was measured with the EORTC core questionnaire (QLQ-C30) and an ESBC-specific questionnaire. Multilevel analysis was used to estimate the effects and interactions of time, treatment and patient characteristics. Most symptoms declined between three months and one year, but arm and menopausal symptoms persisted. Emotional, social and role functioning improved over time, and fear of disease recurrence diminished. Younger women faired worse than older women on a broad range of QoL dimensions. Single women and those with less education faired worse on a number of dimensions. The negative impact of mastectomy on body image was greatest among married women, particularly young married women. These sociodemographic distinctions are relevant when discussing treatment options with women facing a diagnosis of ESBC.

Local recurrence after mastectomy and adjuvant CMF: implications for adjuvant radiation therapy.

BACKGROUND: The purpose of the present study was to evaluate the patterns of failure in a series of patients with node-positive breast cancer that was treated by total mastectomy and adjuvant chemotherapy. METHODS: A retrospective review was undertaken of 217 patients with node-positive breast cancer who were referred to the oncology departments of Westmead and Nepean Hospitals following total mastectomy between January 1980 and December 1991. The majority of patients (82%) were pre- or peri-menopausal and all underwent chemotherapy with cyclophosphamide, methotrexate and 5-fluorouracil (CMF) by either an oral or intravenous regimen. No patient received adjuvant radiation therapy. RESULTS: After a median follow up of 8.7 years, 19% of patients had developed a loco-regional recurrence (LRR). The majority of LRR (79%) occurred within the initial 3 years after mastectomy. The risk of LRR was positively associated with the size of the tumour (11% for T1 vs 53% for T3, P < 0.001) and axillary nodal status (16% for three or fewer positive nodes vs 31% for four or more positive nodes, P = 0.017). Patients with T1 or T2 tumours and 1-3 positive nodes had the lowest rate of LRR (11%) while those with T3 tumours or 4-10 positive nodes had the highest rates, ranging from 23 to 75%. Relapse at the chest wall and supraclavicular fossa (SCF) accounted for 46 and 35%, respectively, of all LRR; relapse at the internal mammary chain and axilla was uncommon. CONCLUSION: The data suggest that patients with T3 tumours (> 5 cm) and any nodal involvement or patients with four or more involved axillary nodes, regardless of T stage, are at a high risk of LRR and will benefit from adjuvant radiation therapy to the chest wall and SCF.

Absolute risk of breast cancer for Australian women with a family history.

BACKGROUND: The purpose of the present paper was to estimate the absolute risk of breast cancer over the remainder of a lifetime in Australian women with different categories of family history. METHODS: Age-specific breast cancer incidence rates were adjusted for screening effects, and rates in those with no family history were estimated using the attributable fraction (AF). Relative risks from a published meta-analysis were applied to obtain incidence rates for different categories of family history, and age-specific incidence was converted to cumulative risk of breast cancer. The risk estimates were based upon Australian population statistics and published relative risks. Breast cancer incidence was from New South Wales women for 1996. The AF was calculated using prevalence of a family history of breast cancer from data on Queensland women. The cumulative absolute risk of breast cancer was calculated from decade and mid-decade ages to age 79 years, not adjusted for competing causes of death. RESULTS: Lifetime risk is approximately 8.6% (1 in 12) for the general population and 7.8% (1 in 13) for those without a family history. Women with one relative affected have lifetime risks of 1 in 6-8 and those with two relatives affected have lifetime risks of 1 in 4-6. The cumulative residual lifetime risk decreases with advancing age; by age 60 years all groups with only one relative affected have well above a 90% probability of not developing breast cancer to age 79 years. CONCLUSIONS: These Australian risk statistics are useful for public information and in the clinical setting. Risks given here apply to women with average breast cancer risk from other risk factors.

Projecting mammographic screens.

OBJECTIVE: The purpose of mammographic screening is to reduce mortality from breast cancer. This study describes a method for projecting the number of screens to be performed by a mammographic screening programme, and applies this method in the context of New South Wales, Australia. METHOD: The total number of mammographic screens was projected as the sum of initial screens and re-screens, and is based on projections of the population, rates of new recruitment, rates of attrition within the programme, and the mix of screening intervals. The baseline scenario involved: 70% participation of women aged 50-69 years, 90% return rate for the second and subsequent re-screens, 5% annual screens (95% biennial screens), and a specified population projection. The results were assessed with respect to variations in these assumptions. RESULTS: The projections were strongly influenced by: the rate of screening of the target age group; the proportion of women re-screened annually; and the rates of attrition within the programme. Although demographic change had a notable effect, there was little difference between different population projections. Standard assumptions about attrition within the programme suggest that the current target participation rates in NSW may not be achieved in the long term. CONCLUSIONS: A practical model for projecting mammographic screens for populations is described which is capable of forecasting the number of screens under different scenarios. IMPLICATIONS: Projections of mammographic screens provide important information for the planning and financing of equipment and personnel, and for testing the effects of variations in important operational parameters. Re-screening attrition is an important contributor to screening viability.

Predictors of local recurrence after treatment of ductal carcinoma in situ: a meta-analysis.

BACKGROUND: Management of patients with ductal carcinoma in situ (DCIS) is a dilemma, as mastectomy provides nearly a 100% cure rate but at the expense of physical and psychologic morbidity. It would be helpful if we could predict which patients with DCIS are at sufficiently high risk of local recurrence after conservative surgery (CS) alone to warrant postoperative radiotherapy (RT) and which patients are at sufficient risk of local recurrence after CS + RT to warrant mastectomy. The authors reviewed the published studies and identified the factors that may be predictive of local recurrence after management by mastectomy, CS alone, or CS + RT. METHODS: The authors examined patient, tumor, and treatment factors as potential predictors for local recurrence and estimated the risks of recurrence based on a review of published studies. They examined the effects of patient factors (age at diagnosis and family history), tumor factors (sub-type of DCIS, grade, tumor size, necrosis, and margins), and treatment (mastectomy, CS alone, and CS + RT). The 95% confidence intervals (CI) of the recurrence rates for each of the studies were calculated for subtype, grade, and necrosis, using the exact binomial; the summary recurrence rate and 95% CI for each treatment category were calculated by quantitative meta-analysis using the fixed and random effects models applied to proportions. RESULTS: Meta-analysis yielded a summary recurrence rate of 22.5% (95% CI = 16.9-28.2) for studies employing CS alone, 8.9% (95% CI = 6.8-11.0) for CS + RT, and 1.4% (95% CI = 0.7-2.1) for studies involving mastectomy alone. These summary figures indicate a clear and statistically significant separation, and therefore outcome, between the recurrence rates of each treatment category, despite the likelihood that the patients who underwent CS alone were likely to have had smaller, possibly low grade lesions with clear margins. The patients with risk factors of presence of necrosis, high grade cytologic features, or comedo subtype were found to derive the greatest improvement in local control with the addition of RT to CS. Local recurrence among patients treated by CS alone is approximately 20%, and one-half of the recurrences are invasive cancers. For most patients, RT reduces the risk of recurrence after CS alone by at least 50%. The differences in local recurrence between CS alone and CS + RT are most apparent for those patients with high grade tumors or DCIS with necrosis, or of the "comedo" subtype, or DCIS with close or positive surgical margins. CONCLUSIONS: The authors recommend that radiation be added to CS if patients with DCIS who also have the risk factors for local recurrence choose breast conservation over mastectomy. The patients who may be suitable for CS alone outside of a clinical trial may be those who have low grade lesions with little or no necrosis, and with clear surgical margins. Use of the summary statistics when discussing outcomes with patients may help the patient make treatment decisions.

Prognosis after breast recurrence following conservative surgery and radiotherapy in patients with node-negative breast cancer.

BACKGROUND: Breast conservation surgery with radiotherapy is a safe and effective alternative to mastectomy for early-stage breast cancer. This retrospective study examined the outcome of patients with isolated local recurrence following conservative surgery and radiotherapy in node-negative breast cancer. METHODS: Between November 1979 and December 1994, 503 women with node-negative breast cancer were treated by conservation surgery and radiotherapy without adjuvant systemic therapy. RESULTS: After a median follow-up of 73 months the 5-year rate of freedom from local recurrence was 94 per cent. Thirty-five patients developed an isolated local recurrence within the breast as a first event. Thirty-three patients were treated with salvage mastectomy and two patients were treated with systemic therapy alone. The 5-year rate of freedom from second relapse was 46 per cent and the overall 5-year survival rate was 59 per cent for patients who had salvage mastectomy. Patients who developed breast recurrence as a first event had a 3.25 greater risk of developing distant metastasis (P < 0.001) than those who did not have breast recurrence as a first event. CONCLUSION: Salvage mastectomy after local recurrence was an appropriate treatment if there was no evidence of distant metastasis. Breast recurrence after conservative surgery and radiotherapy in node-negative breast cancer predicted an increased risk of distant relapse.

Conservative surgery and radiation therapy for invasive lobular carcinoma of the breast.

BACKGROUND: There is debate as to whether infiltrating lobular carcinoma (ILC) can be effectively treated with breast conservative surgery (CS) and radiotherapy (RT) because of a perceived high risk of local recurrence. This retrospective study examined the outcome of patients with ILC treated by CS and RT. METHODS: Between November 1979 and December 1994, 57 women with UICC Stage I or II ILC were treated by CS and RT at Westmead Hospital, New South Wales, Australia. The median age was 55 years (range 28-79). Twelve patients (21%) underwent a re-excision after initial CS. The final margins were clear for 43 patients (75.4%), positive (invasive or in situ) for nine patients (15.8%), and indeterminate for five patients (8.8%). All patients received whole-breast irradiation (45-50.4 Gy) usually supplemented by a boost (10-30 Gy). Fifty-three of 57 patients (93%) had their pathology reviewed at Westmead Hospital. RESULTS: After a median follow up of 69 months (range 36-162) three patients (5.3%) developed a local recurrence. One of 43 patients (2.3%) with known clear margins developed a local recurrence compared with two of 14 patients (14.3%) with positive or indeterminate margins (P = NS). The 5- and 10-year rates of freedom from local recurrence were 96 and 93%, respectively. The 5-year disease-free survival was 85% (node-negative, 92%; node-positive, 66%). Overall survival was 94% at 5 years. No patient developed a contralateral breast cancer. CONCLUSION: Patients with ILC can be effectively treated with CS and RT.

The value of S-phase and DNA ploidy analysis as prognostic markers for node-negative breast cancer in the Australian setting.

This study aimed to determine the prognostic significance of DNA ploidy and S-phase fraction (SPF) measurements in our laboratory for patients with node-negative breast cancer. Frozen tumors from axillary node-negative breast cancer patients (n = 50) treated at Westmead Hospital, NSW, between 1988 and 1991 were analysed by flow cytometry. The median duration of follow-up for all patients was 8.4 years. Forty-six specimens provided evaluable DNA histograms with 43% (n = 20) diploid and 56% (n = 26) aneuploid tumors identified. Comparisons of DNA ploidy status and SPF were made with traditional prognostic variables, which included age, menopausal status, tumor size, histologic grade and hormone receptor status. Our results showed that there was no significant difference in disease-free or overall survival between patients with diploid and aneuploid tumors. Histologic grade 3 tumors were more likely to be aneuploid and had higher SPF than grade 1 or 2 tumors. Patients with grade 3 tumors and a high SPF were four times more likely to relapse than the rest of the population. These results indicate that DNA flow cytometric analysis in our laboratory provides additional prognostic data that could be utilised alongside traditional clinical and histopathologic indicators for predicting outcome for patients.

Inflammatory breast cancer: enhanced local control with hyperfractionated radiotherapy and infusional vincristine, ifosfamide and epirubicin.

Local control rate for inflammatory breast cancer (IBC) is < 50% with standard chemotherapy-radiotherapy regimen. Nineteen women (age range 40-65, median 50 years) with IBC (18 patients) or with a primary tumour of > 10 cm (one patient) received a novel treatment comprising hyperfractionated radiotherapy (HFRT) sandwiched between two cycles of infusional chemotherapy using vincristine, ifosfamide and epirubicin (VIE). The primary endpoint was local control. VIE was continuously infused for six weeks via a Hickman's line using a Deltec CADD-1 ambulatory pump. Ifosfamide (3 gm/m2) mixed with equi-dose mesna was infused for seven days and alternated every week with an infusion of epirubicin (50 mg/m2) mixed with vincristine (1.5 mg/m2). HFRT consisted of 1.5 Gy twice daily for 34 frct (51 Gy) followed by a boost of 15 Gy in 10 frct. The total treatment time was less than 22 weeks. Median follow-up was 37 months. Local control rate was 58%. Three patients failed to respond initially and five relapsed in the breast at a median time of 36.8 months. Median overall and disease-free survival was 18 and 25.3 months respectively. Toxicity from VIE was minimal (WHO gd 3 emesis--two patients, gd 3 mucositis--one patient, neutropenic sepsis--three patients). Radiotherapy caused moist desquamation in 17/19 patients. Twenty-four central lines were complicated by seven line infections, three thromboses, and one extravasation. The local control rate of 58% with VIE + HFRT appears similar to reported chemoradiotherapy regimen, although the treatment time of 22 weeks is much shorter than other regimens which take up to 12 months. Toxicity is acceptable. Hickman-related complications need to be reduced. The study is ongoing.
