High-dose epirubicin in locally advanced operable noninflammatory breast cancer: a feasibility trial

AIMS AND BACKGROUND: Anthracyclines are among the most active agents for the treatment of patients with locally advanced breast cancer. The aim of our study was to evaluate the feasibility and activity of a relatively high-dose regimen with 4-epirubicin plus normal doses of cyclophosphamide over a short period of time without the use of hematologic growth factors as adjuvant in resected locally advanced breast cancer. METHODS: Between January 1990 and June 1992, 43 consecutive patients, premenopausal or postmenopausal < 60 yrs, were surgically resected and then treated with epirubicin plus cyclophosphamide for at least 4 cycles (maximum 6). Electron beam (6-10 MeV energy) radiotherapy was delivered on the chest wall in patients with pathological skin infiltration (pT4b). RESULTS: Median age was 46 years (range, 27-59); 37 were premenopausal and 6 postmenopausal. The total number of administered cycles was 202 (6 in 15 patients and 4 in 28 patients); 195/202 (96.5%) were administered at full dose, and 7 (3.5%) were reduced to 75% of the planned dosage. The three-year disease-free survival was 67% for stage IIIa and 61% for stage IIIb patients. The three-year overall survival was 88% and 79%, respectively. Local relapse only was reported in one patient (2%), distant relapse in 11 patients (25%), and local and distant relapse in four patients (9%). Toxicity was acceptable and mainly hematologic. CONCLUSIONS: Our trial showed that the regimen is feasible without the use of hematologic growth factors. In this era of cost containment, the use of this short-term, high-dose induction course instead of repetitive courses of conventional dose regimens merits further evaluation, possibly in a large randomized trial.     

Prospectively randomized trial of postoperative adjuvant chemotherapy in patients with high-risk colon cancer

PURPOSE: This study had two major goals: (1) to assess the effectiveness of a regimen of fluorouracil (5-FU) plus levamisole plus leucovorin as postoperative surgical adjuvant therapy for patients with high-risk colon cancer, and (2) to evaluate 6 months versus 12 months of chemotherapy. PATIENTS AND METHODS: Patients with poor-prognosis stage II or III colon cancer were randomly assigned to receive adjuvant chemotherapy with either intensive-course 5-FU and leucovorin combined with levamisole, or a standard regimen of 5-FU plus levamisole. Patients were also randomly assigned to receive either 12 months or 6 months of chemotherapy, which resulted in four treatment groups. RESULTS: Eight hundred ninety-one of 915 patients entered (97.4%) were eligible. The median follow-up duration is 5.1 years for patients still alive. There was a difference among the four treatment groups with respect to patient survival, and a significant duration-by-regimen interaction was observed. Specifically, standard 5-FU plus levamisole was inferior to 5-FU plus leucovorin plus levamisole when treatment was given for 6 months (5-year survival rate, 60% v 70%; P < .01). CONCLUSION: There was no significant improvement in patient survival when chemotherapy was given for 12 months compared with 6 months. When chemotherapy was given for 6 months, standard 5-FU plus levamisole was associated with inferior patient survival compared with intensive-course 5-FU plus leucovorin plus levamisole. These data suggest that 5-FU plus levamisole for 6 months should not be used in clinical practice, whereas 6 months of treatment with 5-FU plus leucovorin plus levamisole is effective.     

Long-term follow-up of a randomized post-induction therapy trial in acute myelogenous leukemia (a Southeastern Cancer Study Group trial)

A phase III clinical trial was designed to determine if more intensive induction and consolidation therapy for acute myeloblastic leukemia increases the remission rate and prolongs survival. A minor objective was to determine if the use of non-cross resistant drugs was more effective than the same drugs used for induction. Patients with untreated leukemia between the ages of 15 and 50 were given daunorubicin 45 mg/m2 for the first 3 days of a 10-day continuous infusion of cytosine arabinoside, initially at a dose of 2000 mg/m2 but reduced to 100 mg/m2 because of toxicity. Those under 36 achieving a complete remission and with an histocompatible donor were assigned to a transplant arm. The rest were randomized to receive one of three consolidation arms: A, cytosine arabinoside, 200 mg/m2 daily for 7 days and daunorubicin 45 mg/m2 daily for 3 days for three courses; B, one course as in Arm A followed by amsacrine, 120 mg/m2 daily for 5 days followed by a 5-day continuous infusion of azacytidine, 150 mg/m2/day; C, thioguanine and cytosine arabinoside, 100 mg/m2 every 12 h and daunorubicin 10 mg/m2 daily for 5 days for three courses followed by four maintenance courses of cytosine arabinoside, 100 mg/m2 daily for 5 days and daunorubicin, 45 mg/m2 for 2 days every 13 weeks. From 1981 to 1986, 398 eligible patients were enrolled and 219 achieved a complete remission. The initial induction dose of cytosine arabinoside was reduced after five of 29 patients exhibited fatal gastrointestinal toxicity. Only 11 patients were assigned to the transplant arm. There were no significant differences in the consolidation arms. The 5 year disease-free survivals were 38, 31 and 27% in arms A, B, and C respectively. Intensive consolidation therapy with the same or different drugs used in induction was as effective as lower dose consolidation followed by maintenance therapy.     

A comparative study of 4 sequential first-line chemotherapy protocols in locally advanced breast cancer]

The toxic effect of Silesian air pollutants to mouse organs was examined. Histological changes were found in the examined lymphoid organs (thymus, spleen) as well nonlymphoid organs (liver, kidneys). The alterations in weight indexes of lymphoid organs were also observed. Considerable changes in cellularity, weight index, and histology of the thymus in the mice exposed to air pollutants suggest the atrophy of this organ, which may lead to extrathymic T-cell differentiation and even acceleration of thymocytes maturation, which may lead to certain allergic or auto-immune pollutants of all investigated mouse organs in the following order: thymus, liver, kidneys, and spleen.     

A cooperative randomized controlled study of adjuvant chemoendocrine therapy for breast cancer in Japan

Social competence in subjects at risk for schizophrenia and affective disorder and in normal-comparison subjects was examined in childhood and adolescence. Based on interviews with the parents of the subjects and with the children and adolescents themselves, subjects at risk for schizophrenia had poorer overall social competence than subjects at risk for affective disorder and comparison subjects in early adolescence and adolescence but not in childhood. In analyses of specific aspects of social competence, the adolescents at risk for schizophrenia had significantly poorer peer relationships and decreased hobbies/interests than the adolescents at risk for affective disorder and the normal-comparison adolescents. With respect to school adjustment, however, the two groups of adolescent offspring of parents with psychiatric disorders had significantly poorer adjustment than the comparison adolescents but did not differ from each other on this measure. These results suggest that various aspects of poor social competence may precede the onset of schizophrenia and play an important role in its development.     

Feasibility of adjuvant chemotherapy for breast cancer patients

The prevalence and natural history of severe proteinuria in mild to moderate hypertension are not completely defined. We screened 1635 men with a history of hypertension and randomized 1292 with untreated diastolic blood pressure (DBP) 95-109 mmHg to single-drug treatment with either hydrochlorothiazide, atenolol, captopril, clonidine, diltiazem-SR, prazosin, or placebo in a double-blind prospective trial. Twenty-seven of 1635 patients (1.7%) satisfying clinical criteria for primary hypertension were found to have developed proteinuria > 1000 mg/24 hours and were removed from the study. Follow-up data were obtained on 19 of these 27 patients. One patient was found to have focal segmental sclerosis and progressed to end-stage renal disease. Three other patients developed severe (serum creatinine > 3.5 mg/dl) chronic renal failure (one with diabetic nephropathy), one progressed from serum creatinine 1.4 to 2.2 mg/dl, but 14 of the 19 remained with stable serum creatinine < 2.0 mg/dl on follow-up for 6-9 years. Data were available for 1076 of 1155 (93%) treated study patients at end titration, 522/600 (87%) at one year and 322/444 (73%) at two years. There were significant associations for proteinuria with obesity and higher systolic blood pressure. There was a trend toward significant difference in mean 24-hour protein excretion rates at baseline between black (127 mg) and white (139 mg) patients (p = 0.07). There were no statistically significant changes in urinary protein excretion/24 hours between or within the different treatment groups (including placebo). Eighteen patients were removed from the study during the active treatment phase for proteinuria > 1000 mg/24 hours: hydrochlorothiazide 4, placebo 3, diltiazem 3, prazosin 3, atenolol 2, clonidine 2, and captopril 1. We conclude: (1) the prevalence of severe (> 1 g/24 hours) proteinuria in the hypertensive population is significant but does not necessarily imply a poor prognosis; (2) mean 24-hour urinary protein excretion rates did not vary in response to the different classes of antihypertensive drugs; and (3) there was no drug-specific increase in proteinuria detected in this study.     

Breast conservation and prolonged chemotherapy for locally advanced breast cancer: the University of Michigan experience

PURPOSE: To determine whether breast conservation and prolonged neoadjuvant chemotherapy have efficacy in locally advanced breast cancer (LABC), as measured by survival and rate of breast conservation. MATERIALS AND METHODS: Eighty-nine patients with stage III disease were enrolled at the University of Michigan (UM) onto a prospective nonrandomized trial. Patients received nine 21-day cycles of neoadjuvant chemohormonal therapy that consisted of doxorubicin 30 mg/m2 and cyclophosphamide 750 mg/m2 intravenously on day 1, conjugated estrogens 0.625 mg orally twice daily on days 6 to 8, methotrexate 40 mg/m2 and fluorouracil 500 mg/m2 intravenously on day 8, and tamoxifen 10 mg orally twice daily on days 9 to 14. Patients with a negative biopsy received radiation only, while those with residual disease underwent mastectomy and postoperative radiotherapy. Eight more cycles of chemohormonal therapy were administered after local-regional therapy. RESULTS: The clinical response rate to neoadjuvant therapy was 97%, 28% of patients had a complete pathologic response evaluated at biopsy. Five-year overall and disease-free survival probabilities were 54% and 44%, respectively. The median disease-free survival time was 2.4 years. The 5-year actuarial rates of local-regional control with local failure as only first failure were 82% and 78% following radiotherapy, and mastectomy and radiotherapy, respectively (P = .99). CONCLUSION: Prolonged neoadjuvant chemohormonal therapy and biopsy-driven local therapy have efficacy in LABC, with 28% of patients being candidates for breast conservation and a 5-year overall survival rate of 54%.     

Successful multimodal therapy of a locally advanced non-small-cell bronchial cancer

HISTORY AND CLINICAL FINDINGS: A chest radiogram, performed on a 60-year-old man with unproductive cough for 3 months, showed a space-occupying lesion in the right upper lobe, and breath sounds were diminished in this area. He had been a heavy smoker. His general condition and nutritional state were good. INVESTIGATIONS: Computed tomography, skeletal scintigraphy, bronchoscopy with biopsy and mediastinoscopy established the diagnosis of a locally advanced non-small-cell bronchial carcinoma (stage IIIB or T2N3M0). TREATMENT AND COURSE: Combined adjuvant treatment was begun in the hope of improving the median survival time of 8 months predicted for this tumour stage. After two cycles of a combined chemotherapy scheme (ifosfamide, carboplatin, etoposide) he received hyperfractionated-accelerated radiotherapy (total dose 45 Gy; 1.5 Gy twice daily) together with carboplatin and vindesine. This was followed by a right upper lobectomy with lymphadenectomy. Full remission was confirmed in both the resected specimen and the lymph nodes. The patients remains free of tumour 30 months after the diagnosis. CONCLUSION: Neoadjuvant treatment can significantly improve the prognosis of non-small-cell bronchial carcinoma in stage III. Such patients should therefore be treated according to the appropriate study protocol, if possible.     

Accelerated-interrupted radiation therapy given concurrently with chemotherapy for locally advanced non-small cell lung cancer

PURPOSE: To evaluate the efficacy of multidrug chemotherapy combined with accelerated radiation therapy in the treatment of localized but unresectable non-small cell lung cancer. PATIENTS AND METHODS: Between September 1990 and February 1993, 35 patients with Stage III (15 IIIA & 20 IIIB) non-small cell lung cancer were entered on a protocol using combined accelerated radiation therapy and chemotherapy. Radiation therapy consisted of 55.6 Gy in 30 fractions (1.8 Gy bid for 5 consecutive days given in 3 weeks [total of 15 days], every other week). Chemotherapy consisted of cisplatin (10 mg/m2), vinblastine (4 mg/m2), 6-thioguanine (40 mg bid), and 5-fluorouracil (400 mg/m2 as continuous infusion) given concomitantly with radiation therapy. Approximately 3 weeks following completion of radiation therapy, two cycles of consolidation chemotherapy were given, consisting of two doses of cisplatin (120 mg/m2) 4 weeks apart and six doses of vinblastine (4 mg/m2) given on two consecutive days every other week for 3 weeks. RESULTS: Six patients were still alive at last follow-up; for them the median follow-up time is 47 months (range, 39-55.8). The median survival time is 17.5 months. The 1-, 2-, 3- and 4.5-year survival rates are 69%, 37%, 20% and 17%, respectively. Overall response rate is 63%, with 51.5% partial response and 11.5% complete response rates. Esophagitis occurred as follows: Grade 4 = 0, Grade 3 = 1, Grade 2 = 6, and Grade 1 = 13. No patient developed Grade 3 or 4 acute respiratory toxicity. Significant hematologic toxicity occurred as follows: 37% Grade 3 and 31% Grade 4 leukopenia. Radiation pneumonitis occurred in two patients. DISCUSSION: The regimen tested in this protocol appears to be very well tolerated with minimal pulmonary or esophageal toxicity. This, coupled with the shortened course of radiation therapy and the ability to deliver the combined radiation and chemotherapy portion of the treatment on an outpatient basis most of the time, has made multi-modality treatment for this malignancy much easier and more convenient for patients. In addition, the favorable survival in this group of patients with locally advanced disease is very encouraging and warrants further study.     

Induction chemotherapy followed by breast conservation for locally advanced carcinoma of the breast

BACKGROUND: Few women with locally advanced breast cancer remain disease-free, even for 2 years. Response to induction chemotherapy may be associated with longer disease-free and overall survival rates. The role of breast conservation in selected patients with response to induction chemotherapy was evaluated. METHODS: Since 1979, patients with Stages IIB and III breast cancer have undergone induction chemotherapy; patients with response continued chemotherapy until a plateau of regression was achieved. Before 1983, all patients having a response to chemotherapy underwent mastectomy; since 1983, selected patients have undergone breast conservation. Outcomes were tallied comparing these two groups of patients. RESULTS: The study group included 189 women, who were followed up for 12-159 months (median, 46 months) after diagnosis. Of the patients, 85% had a response to induction chemotherapy. Patients with no response were excluded from additional consideration in this study. One hundred three (64%) women underwent mastectomy; 55 (36%) were treated with breast conservation. The disease-free 5-year survival rate was 61% for all patients with a response to chemotherapy; 56% for those having mastectomy and 77% for those having breast conservation. The overall 5-year survival rate was 69% for all patients with a response to chemotherapy, 67% for those undergoing mastectomy and 80% for those having breast conservation. CONCLUSIONS: Induction chemotherapy achieves significant tumor regression in most women with locally advanced breast cancer, permitting subsequent breast conservation or mastectomy with a greater expectation of long-term success. Breast conservation is used more frequently with the same expectation of success as mastectomy, presuming careful selection based on response to chemotherapy.     

Adjuvant systemic chemotherapy and hormonal therapy. Effect on local recurrence in the conservatively treated breast cancer patient

BACKGROUND: The purpose of this study is to determine the impact of adjuvant systemic chemotherapy and adjuvant hormonal therapy on local relapse in the conservatively treated breast. MATERIALS AND METHODS: Before December 1989, 548 patients underwent lumpectomy with axillary dissection followed by radiation therapy to the intact breast. Adjuvant systemic therapy was administered as clinically indicated. The majority of patients with pathologically involved lymph nodes received adjuvant systemic therapy, whereas those with pathologically negative lymph nodes received no adjuvant systemic therapy. The majority of patients received a course of radiation therapy either concomitant with or before systemic therapy. In only nine cases was radiation therapy delayed more than 16 weeks after surgery. RESULTS: As of June 1992, the 548 patients had a median follow-up of 6.4 years. In univariate and multivariate Cox regression analysis, patient age and adjuvant systemic chemotherapy were statistically significant independent prognostic factors relating to breast relapse. Those patients who received adjuvant systemic chemotherapy had a lower breast relapse than those who did not. Among patients who received tamoxifen, there was a statistically insignificant trend toward a lower relapse rate compared with those who did not receive tamoxifen. CONCLUSIONS: It appears from this retrospective analysis that patients who received adjuvant systemic therapy, either concomitantly or after their course of radiation therapy, had a lower relapse rate in the conservatively treated breast than those patients who received no adjuvant systemic therapy.     

A case of locally advanced breast cancer successfully treated with intra-arterial infusion chemotherapy of high-dose epirubicin

A case of locally advanced breast cancer was treated with intra-arterial infusion chemotherapy using high-dose epirubicin. The 1st and 2nd cycle consisted of 210 mg (day 1, 4, 7) and 150 mg (day 1, 4, 7), respectively. After completion of 2 cycles of the regimen, remarkable loco-regional control and improved QOL were obtained. Leucopenia (nadir; 1,000/mm3) was the dose limiting factor, but well-tolerated with supportive therapy. The patient underwent salvage surgery and maintenance intra-venous chemotherapy (epirubicin; 30 mg/3 weeks). At this writing, the patient is enjoying favorable QOL. These findings suggested that this modality was effective for cases with exctensive loco-regional involvement.     

An evaluation of early or delayed adjuvant chemotherapy in premenopausal patients with advanced breast cancer undergoing oophorectomy

We treated randomly 75 premenopausal patients with advanced breast cancer with combination chemotherapy (5-fluorouracil, cyclophosphamide and prednisone), either as an early adjunct to oophorectomy or as a delayed treatment upon appearance of progressive metastatic disease after operation. The group receiving early systemic chemotherapy enjoyed an improved response rate, an improved survival rate and, most importantly, an improved progression-free interval (median of 53 versus 17 weeks). With the exclusion of the group with early (within three weeks after oophorectomy) progression, the progression-free intervals had a median duration of 77 weeks in the early-treatment group versus 33 weeks in the control group. The early-progression group did exceedingly poorly, although systemic chemotherapy was employed at that juncture, having a median survival of 22 weeks as compared to 144 weeks in the immediate-treatment group and 105 weeks in the control group.     

Tumor clearance of technetium 99m-sestamibi as a predictor of response to neoadjuvant chemotherapy for locally advanced breast cancer

PURPOSE: Since we have previously shown that the efflux rate of technetium 99m (99mTc) sestamibi, a transport substrate of P-glycoprotein (Pgp), is directly correlated with Pgp levels in untreated breast carcinoma, we tested whether tumor clearance of 9mTc-sestamibi may be predictive of therapeutic response to neoadjuvant chemotherapy in patients with locally advanced breast cancer. PATIENTS AND METHODS: Thirty-nine patients with stage III disease, median tumor diameter 5.8 cm (range, 3 to 10) were enrolled onto this prospective clinical trial and underwent 99mTc-sestamibi scan before neoadjuvant chemotherapy. Patients were injected intravenously (i.v.) with 740 MBq of 99mTc-sestamibi; a 15-minute dynamic study was performed, and static planar images were obtained at 0.5, 1, 2, and 4 hours. The time to half clearance of 99mTc-sestamibi was calculated in each patient from decay corrected time-activity curves using a monoexponential fitting. Patients were treated with epirubicin 150 mg/m2 i.v. every 2 weeks for three courses and then underwent surgery within 3 weeks from the completion of chemotherapy. Residual tumor was assessed by pathologic examination of mastectomy specimens. RESULTS: Seventeen of 39 patients showed a rapid tumor clearance of 9mTc-sestamibi (time to half clearance [t1/2] < or = 204 minutes) and 15 of these 17 (88%) showed a highly cellular macroscopic residual tumor at histology that indicated lack of tumor response to neoadjuvant chemotherapy. In contrast, only eight of 22 (36%) with prolonged retention of 99mTc-sestamibi (t1/2 > 204 minutes) showed residual macroscopic tumor at histology (Fisher's exact test, P < .01). CONCLUSION: A rapid tumor clearance of 99mTc-sestamibi may predict lack of tumor response to neoadjuvant chemotherapy with drugs affected by the multidrug-resistant phenotype in patients with locally advanced breast carcinoma.     

Preoperative chemotherapy followed by concurrent chemoradiation therapy based on hyperfractionated accelerated radiotherapy and definitive surgery in locally advanced non-small-cell lung cancer: mature results of a phase II trial

The ability of rats to learn the location of a hidden platform in a swim maze was compared in animals with excitotoxic lesions of the anterior or posterior (retrosplenial) cingulate cortex or radiofrequency lesions of the cingulum bundle or fimbria-fornix. Performance of this allocentric spatial task was unaffected by the posterior cingulate cortex lesions, while anterior cingulate cortex damage produced only a mild acquisition deficit. Transection of the fornix and lesions of the cingulum bundle produced similar patterns of impairment on initial acquisition, but the cingulum bundle lesions had less effect on reversal of the task. The results from the water maze, and from a subsequent T-maze alternation task, indicate that cingulum bundle lesions can produce a spatial deficit that is similar, but milder, to that observed after fornix transection. The results of the excitotoxic lesions suggest that previous studies examining conventional cingulate lesions may have been influenced by damage to adjacent fibre tracts, such as the cingulum bundle.     

Role of axillary lymph node dissection after tumor downstaging with induction chemotherapy for locally advanced breast cancer

BACKGROUND: Induction chemotherapy has become the standard of care for patients with locally advanced breast cancer (LABC) and currently is being evaluated in prospective clinical trials in patients with earlier-stage disease. To better gauge the role of axillary lymph node dissection in patients with LABC this study was performed to assess initial axillary status on physical and ultrasound examination, axillary tumor downstaging following induction chemotherapy, and the accuracy of physical examination compared with axillary sonography in predicting which patients will have axillary lymph node metastases found on pathologic examination. METHODS: Between 1992 and 1996, 147 consecutive patients with LABC were registered in a prospective trial of induction chemotherapy using 5-fluorouracil, doxorubicin, and cyclophosphamide. Physical and ultrasound examinations of the axilla were performed at diagnosis and after induction chemotherapy. Segmental resection with axillary lymph node dissection or modified radical mastectomy was performed, followed by postoperative chemotherapy and irradiation of the breast or chest wall and regional lymphatics. RESULTS: Following induction chemotherapy, 43 (32%) of the 133 patients with clinically positive lymph nodes on initial examination had axillary tumor downstaging as assessed by physical and ultrasound examination. The sensitivity of axillary sonography in identifying axillary metastases was significantly higher than that of physical examination (62% vs. 45%, P=.012). The specificity of physical examination (84%) was higher than that of sonography (70%), but the difference did not reach statistical significance. Among the 55 patients in whom the findings of both physical and ultrasound examination of the axilla were negative following induction chemotherapy, 29 patients (53%) were found to have axillary lymph node metastases on pathologic examination of the axillary contents. However, 28 (97%) of these patients had either 1 to 3 positive lymph nodes or only micrometastases 2 to 5 mm in diameter. CONCLUSIONS: Preoperative clinical assessment of the axilla by physical examination combined with ultrasound examination is not completely accurate in predicting metastases in patients with LABC following tumor downstaging. However, patients with negative findings on both physical and ultrasound examinations of the axilla may be potential candidates for omission of axillary dissection if the axilla will be irradiated because minimal axillary disease remains. Patients who have positive findings on preoperative physical or ultrasound examinations should receive axillary dissection to ensure local control. A prospective randomized trial of axillary dissection versus axillary radiotherapy in patients with a clinically negative axilla following induction chemotherapy is currently underway.     

Phase II trial of weekly paclitaxel and concurrent radiation therapy for locally advanced non-small cell lung cancer

We conducted a prospective Phase II study to determine the response rate, toxicity, and 2-year survival rate of concurrent weekly paclitaxel and radiation therapy (RT) for locally advanced unresectable non-small cell lung cancer. The weekly paclitaxel regimen was designed to optimize the radiosensitizing properties of paclitaxel. Thirty-three patients with unresectable stage IIIA and IIIB non-small cell lung cancer from six institutions were entered into the study between March 1994 and February 1995. Weekly i.v. paclitaxel (60 mg/m2; 3-h infusion) plus concurrent chest RT (60 Gy over 6 weeks) was delivered for 6 weeks. Twenty-nine patients were evaluable for response. Three patients achieved a complete response (10%), and 22 patients (76%) achieved a partial response, for an overall response rate of 86% (95% confidence interval, 68-96%). One patient progressed during the therapy, and three patients had stable disease. Esophagitis was the principal toxicity. Grade 3 or 4 esophagitis occurred in 11 patients (37%). One patient died of pneumonia after completion of therapy. Additional grade > or =3 toxicities included pneumonitis (12%) and neutropenia (6%). One patient had a grade 3 hypersensitivity reaction. The median overall survival duration for all 33 patients who entered the study was 20 months, and 1-, 2-, and 3-year overall survival rates were 60.6%, 33.3%, and 18.2%, respectively. The median progression-free survival duration for all 33 patients was 10.7 months, and 1-, 2-, and 3-year progression-free survival rates were 39.4%, 12.1%, and 6.1%, respectively. Weekly paclitaxel plus concurrent RT is a well-tolerated outpatient regimen. The survival outcome from this regimen is encouraging and seems to be at least equivalent to that of other chemotherapy/radiation trials. These findings warrant further clinical evaluation of weekly paclitaxel/RT in Phase II trials in the neoadjuvant setting and in combination with other cytotoxic agents.
