Extraosseous osteosarcoma: response to treatment and long-term outcome.

PURPOSE: To evaluate the clinicopathologic features of extraosseous osteosarcoma (EOO), a rare soft tissue form of osteosarcoma, and to examine its response to multimodality therapy. PATIENTS AND METHODS: The medical records of all patients with EOO evaluated at The University of Texas M.D. Anderson Cancer Center between 1960 and 1999 were reviewed for clinicopathologic factors, treatment, and outcome. RESULTS: Sixty consecutive patients with EOO were identified, including 38 patients with localized (American Joint Committee on Cancer stages I to III) disease. The majority of patients presented with T2 tumors (n = 35, 58%), and 90% of tumors were located beneath the investing fascia. Twenty-seven patients with measurable and assessable disease were treated with doxorubicin-based chemotherapy (median doxorubicin starting dose, 75 mg/m(2); median number of cycles, four). The overall response rate was 19%, with two complete and three partial responses; one (6%) of 18 doxorubicin-treated patients who underwent subsequent surgery had a pathologic complete response. For the subset of 30 patients with localized disease treated at M.D. Anderson, the 5-year actuarial local recurrence-free, distant recurrence-free, event-free, and disease-specific survival rates were 82% (95% confidence interval [CI], 70% to 98%), 64% (95% CI, 43% to 93%), 47% (95% CI, 30% to 70%), and 46% (95% CI, 26% to 80%), respectively. CONCLUSION: EOO should be considered clinically and therapeutically distinct from osseous osteosarcoma. Radiographic response rates and pathologic complete response rates to doxorubicin-based systemic therapy are low.

A phase II trial of preoperative mitomycin, cisplatin and 5-fluorouracil in adenocarcinoma of the oesophagus.

The effect of neoadjuvant chemotherapy in patients with apparently operable adenocarcinoma of the oesophagus has been investigated. Two courses of mitomycin, cisplatin and 5-fluorouracil (MCF) were given, followed by a radiological evaluation of response. Twenty-two of 25 patients completed both courses. Two showed a complete response and 12 a partial response. There was a pathological complete response of the primary tumour in only one patient (although there was residual secondary tumour in a local lymph node). The main toxicity was myelosuppression, with 9/22 patients having the second chemotherapy course delayed. There were three sudden deaths, one due to a pulmonary embolus and two due to complications of infections. Twenty-one patients underwent surgical exploration; there were 18 resections. Although the radiological response rate of MCF (14/25; 56%; 95% CI 37-75) appeared promising, there were no pathological complete responders. Further Phase II trials are needed to identify more efficacious agents and regimens that will yield a pathological response rate of at least 10%, before proceeding to randomized trials of neoadjuvant chemotherapy for adenocarcinoma of the oesophagus.

Preoperative high-dose cisplatin versus moderate-dose cisplatin combined with ifosfamide and mitomycin in stage IIIA (N2) non small-cell lung cancer: results of a randomized multicenter trial.

Preoperative chemotherapy has become an accepted treatment for stage IIIA (N2) non small-cell lung cancer (NSCLC). The majority of induction regimens employ cisplatin, although the importance of cis-platin dose in combination is unclear. A randomized trial was conducted to address whether higher pre-operative cisplatin doses result in improved survival and increased pathologic complete response in NSCLC. Patients with stage IIIA clinically enlarged and biopsy-proven N2 lesions were randomly assigned to receive either high-dose cisplatin (HDCP) (100 mg/m2) or moderate-dose cisplatin (MDCP) (50 mg/ m2) in combination with ifosfamide (3 g/m2) and mitomycin (6 mg/m2). Disease was restaged after 3 cycles, and those patients with response or stable disease underwent thoracotomy. From March 1993 to February 1997, 83 patients were randomized: 46 received HDCP, and 37 received MDCP. Clinical characteristics were well matched. Radiographic response rate was 59% for HDCP patients and 30% for MDCP patients (P = 0.01). Thoracotomy was performed in 71 patients (86%), 58 of whom had resectable disease. Complete resection rate was 61% in the HDCP group, and 51% in the MDCP group (P = 0.5). Postoperative mortality was 11%. Pathologic complete response was observed in one patient who received MDCP. Median survival in the HDCP and MDCP groups was 13 and 11 months, respectively (P = 0.3). In conclusion, higher radiographic response rate is observed in patients who receive HDCP, but this study fails to show any significant improvement in either overall survival or pathologic complete response in this group of patients.

Long-term survival after epirubicin, cisplatin and fluorouracil for gastric cancer: results of a randomized trial.

We report the final results of a prospectively randomized study that compared the combination of epirubicin, cisplatin and protracted venous infusion fluorouracil (5-FU) (ECF regimen) with the standard combination of 5-FU, doxorubicin and methotrexate (FAMTX) in previously untreated patients with advanced oesophagogastric cancer. Between 1992 and 1995, 274 patients with adenocarcinoma or undifferentiated carcinoma were randomized from eight oncology centres in the UK and analysed for response and survival. The overall response rate was 46% (95% confidence interval (CI), 37-55%) with ECF, and 21% (95% CI, 13-28%) with FAMTX (P = 0.00003). The median survival was 8.7 months with ECF and 6.1 months with FAMTX (P = 0.0005). The 2-year survival rates were 14% (95% CI, 8-20%) for the ECF arm, and 5% (95% CI, 2-10%) for the FAMTX arm (P = 0.03). Histologically complete surgical resection following chemotherapy was achieved in ten patients in the ECF arm (three pathological complete responses to chemotherapy) and three patients in the FAMTX arm (no pathological complete responses). The ECF regimen resulted in a response and survival advantage compared with FAMTX chemotherapy. The probability of long-term survival following surgical resection of residual disease is increased by this treatment. The high response rates seen with ECF support its use in the neoadjuvant setting.

Induction therapy for esophageal cancer with paclitaxel and hyperfractionated radiotherapy: a phase I and II study.

OBJECTIVE: Induction chemoradiotherapy followed by surgery may improve survival rates among patients with esophageal carcinoma. We designed a novel intense induction regimen with paclitaxel and high-dose hyperfractionated radiotherapy to maximize complete response rates. METHODS: Forty patients with esophageal cancer were treated in a phase I and II trial of induction chemotherapy (cisplatin, 5-fluorouracil, and paclitaxel) at three dosage levels (75, 125, and 100 mg/m2) and concurrent hyperfractionated radiotherapy (45 Gy to the mediastinum, 58.5 Gy to the tumor). The mean age was 62 years, and 32 patients (80%) had adenocarcinoma. Twenty-eight of 40 (70%) patients had locally advanced tumors (T3, or stage IIB or greater). RESULTS: The average hospitalization for induction treatment was 17 days. Toxicity was substantial, with esophagitis necessitating nutritional support the most common complication. The maximum tolerated dose of paclitaxel was 100 mg/m2. Two patients died during induction treatment. Thirty-six patients (90%) underwent resection. The median length of stay was 10 days, and two patients died after the operation. Fourteen of 36 patients (39%) had a pathologic complete response. Patients who received all prescribed chemotherapy had a higher pathologic complete response rate (50%) than did patients who required dose reduction (17%; p = 0.076). The 2-year survival rate was 61% (95% CI 35% to 86%) with a median follow-up of 11.9 months. CONCLUSIONS: Paclitaxel at a dose of 100 mg/m2 appears to have acceptable toxicity. The high pathologic complete response rate in this regimen is encouraging, but it is associated with substantial toxicity. The toxicity of this regimen is not acceptable and will require substantial reduction in the radiation component. Survival data are too short-term to confirm enhanced survival.

Ten-year outcome after combined modality therapy for inflammatory breast cancer.

PURPOSE: To evaluate the long-term outcome of combined modality therapy for inflammatory breast cancer. METHODS AND MATERIALS: The data from 54 women treated between 1983 and 1996 for inflammatory breast cancer were analyzed. Patients with metastatic disease or disease progression on induction chemotherapy were excluded. Induction chemotherapy was given to 52 patients. Mastectomy was performed in 52 patients. Radiotherapy was delivered to the breast or chest wall and regional lymph nodes in all patients. The median follow-up for all patients was 5.1 years. RESULTS: The 5- and 10-year overall survival rate was 56% and 35%, respectively; the corresponding relapse-free survival rates were 49% and 34%. Patients with a pathologic complete response after chemotherapy with or without preoperative radiotherapy had better 5- and 10-year overall survival rates (65% and 46%, respectively) and 5- and 10-year relapse-free survival rates (59% and 50%, respectively) compared with patients without a pathologic complete response. Those patients had a 5- and 10-year relapse-free survival rate of 45% and 27%, respectively. Locoregional failure at 5 and 10 years was 8% and 19%, respectively. CONCLUSION: The outcomes for patients completing multimodality therapy compare favorably with published data; however, the exclusion of patients with progression during induction chemotherapy may account in part for these results. The pathologic complete response rate was found to be an important prognostic factor. Selected patients with inflammatory breast cancer have the potential for long-term survival.

Induction cisplatin and paclitaxel followed by combination chemoradiotherapy with 5-fluorouracil, cisplatin, and paclitaxel before resection in localized esophageal cancer: a phase II report.

BACKGROUND: Multimodality therapy for esophageal cancer holds promise for improving outcome in this lethal disease. On the basis of encouraging data from a phase I trial, we conducted a phase II study of preoperative chemotherapy, followed by concurrent chemoradiotherapy and surgery. METHODS: Patients with clinically staged resectable esophageal cancer were treated with induction cisplatin and paclitaxel, followed by 45 Gy of external beam radiation with concurrent infusional 5-fluorouracil and weekly cisplatin and paclitaxel. Four to eight weeks after multimodality induction, esophagectomy was performed in suitable patients. Study end points were survival, pathologic complete response, and toxicity. RESULTS: Twenty-one patients were enrolled with a median age of 58 years, and all patients were clinically staged II or III. Sixteen (76.2%) patients completed the trial, of whom four (25%) had a pathologic complete response. One patient died from postoperative complications. Grade 3 or 4 toxicity was observed in 76% of patients, and dose-limiting toxicity was seen in 6 of the first 14 patients, thus necessitating a planned dose reduction of paclitaxel. At a median follow-up of 30 months, 13 patients remain alive. The 2-year disease-specific survival for the study population was 78%. CONCLUSIONS: This regimen of multimodality therapy before resection resulted in an encouraging 2-year survival rate but a disappointing rate of pathologic complete response and was toxic, necessitating a predetermined paclitaxel dose reduction. The incorporation of taxanes into induction strategies for esophageal cancer seems promising, but the optimal schedule remains undefined.

Primary chemotherapy with epirubicin and vinorelbine in women with locally advanced breast cancer.

BACKGROUND: To assess the activity and toxicity of primary chemotherapy with epirubicin (60 mg/m2 every other week) and vinorelbine (25 mg/m2, weekly) plus granulocyte colony-stimulating factor (G-CSF) for 12 weeks, in patients with locally advanced breast cancer in a multicenter setting. PATIENTS AND METHODS: Patients with stage IIIA or IIIB breast cancer, not older than 70, were eligible. A two-stage phase II design was applied. Response was assessed clinically, instrumentally and pathologically. RESULTS: Out of 48 enrolled patients, 87.5% received all planned cycles, with a median dose-intensity of 30 mg/m2/week for epirubicin and 23.8 mg/m2/week for vinorelbine. A clinical or instrumental objective response was reached in 42 patients (87.5%, exact 95% CI: 74.7-95.3); significant downstaging was reached in all but one patient; 6 cases had a pathological complete response in the breast, and 2 cases in the lymph nodes too (pathological complete response rate 4.2%, exact 95% CI: 0.5-14.2); a further 2 patients had only microscopic cancer foci at pathological examination of the breast. Radiological tests underestimated the treatment effect on the breast. Toxicity was mild, neutropenia being the most frequent (grade 3-4 in 47% of patients), but never complicated with fever or sepsis. Mild constipation (< or =grade 2) occurred in 35% of patients. Moderate to severe asthenia occurred in 12% of 6 patients. No cardiac toxicity was reported. At 3 years, disease-free survival was 68% and overall survival 81%. CONCLUSION: Primary chemotherapy with epirubicin every other week, weekly vinorelbine and G-CSF support is highly active and well tolerated in patients with locally advanced breast cancer.

Induction chemoradiation and surgical resection for non-small cell lung carcinomas of the superior sulcus: Initial results of Southwest Oncology Group Trial 9416 (Intergroup Trial 0160).

OBJECTIVE: The rate of complete resection (50%) and the 5-year survival (30%) for non-small cell lung carcinomas of the superior sulcus have not changed for 40 years. Recently, combined modality therapy has improved outcome in other subsets of locally advanced non-small cell lung carcinoma. This trial tested the feasibility of induction chemoradiation and surgical resection in non-small cell lung carcinoma of the superior sulcus with the ultimate aim of improving resectability and survival. METHODS: Patients with mediastinoscopy-negative T3-4 N0-1 superior sulcus non-small cell lung carcinoma received 2 cycles of cisplatin and etoposide chemotherapy concurrent with 45 Gy of radiation. Patients with stable or responding disease underwent thoracotomy 3 to 5 weeks later. All patients received 2 more cycles of chemotherapy and were followed up by serial radiographs and scans. Survival was calculated by the Kaplan-Meier method and prognostic factors were assessed for significance by Cox regression analysis. RESULTS: From April 1995 to September 1999, 111 eligible patients (77 men, 34 women) were entered in the study, including 80 (72.1%) with T3 and 31 with T4 tumors. Induction therapy was completed as planned in 102 (92%) patients. There were 3 treatment-related deaths (2.7%). Cytopenia was the main grade 3 to 4 toxicity. Of 95 patients eligible for surgery, 83 underwent thoracotomy, 2 (2.4%) died postoperatively, and 76 (92%) had a complete resection. Fifty-four (65%) thoracotomy specimens showed either a pathologic complete response or minimal microscopic disease. The 2-year survival was 55% for all eligible patients and 70% for patients who had a complete resection. To date, survival is not significantly influenced by patient sex, T status, or pathologic response. CONCLUSIONS: (1) This combined modality treatment is feasible in a multi-institutional setting; (2) the pathologic complete response rates were high; and (3) resectability and overall survival were improved compared with historical experience, especially for T4 tumors, which usually have a grim prognosis.

Multidisciplinary Management of Locally Advanced Breast Cancer.

The treatment of locally advanced breast cancer is aimed at achieving long-term local control with local surgery and/or radiation therapy and at improving disease-free and overall survival through the application of systemic cytotoxic chemotherapy and hormonal therapy. Studies of local therapy alone with surgery or radiotherapy have demonstrated high rates of local recurrence and low rates of long-term survival. The application of anthracycline-based neoadjuvant chemotherapy has resulted in rates of response ranging from 72% to 97%, clinical complete responses of 12-52%, and pathologic complete responses of 4-33%. Multidisciplinary treatment with neoadjuvant therapy, followed by local surgery and/or radiation therapy, followed by additional chemotherapy, has resulted in rates of local control that exceed 80%, and 5-year survival rates exceeding 50% are not unusual. The use of anthracycline-based neoadjuvant chemotherapy in the treatment of locally advanced breast cancer is thus now firmly established. Research in the treatment of locally advanced breast cancer is needed to further define the optimal method of local therapy and the role of new agents such as the taxanes.

[Clinical evaluation of effects from neoadjuvant chemotherapy with epirubicin plus paclitaxel in cases of locally advanced breast cancer--comparative study of treatment with 2 and 4 cycles].

Neoadjuvant chemotherapy of epirubicin plus paclitaxel was administered to 75 patients (including a 2-cycle group of 39 patients and a 4-cycle group of 36 patients) with locally advanced breast cancer (35 cases of stage IIb, 28 of stage IIIa, 12 of stage IIIb) to compare efficacy and toxicity of 2 cycle and 4 cycle regimens. All patients were female. They were treated with epirubicin 60 mg/m2, on day 1, by i.v., followed by paclitaxel 150 mg/m2, by 3 hour continuous infusion on day 2 repeated every 3 weeks. Premedication with dexamethasone, ondansetron, diphenhydramine and cimetidine were administered to prevent gastroenteritic and allergic reactions before chemotherapy. Thirty-nine patients were given 2 cycles and thirty-six were given 4 cycles of this regimen. One of 39 patients had complete response, 28 had partial response and 10 had no change in the 2-cycle group. In addition, 21 of 36 patients had complete response (including 9 who had pathologic complete response), 13 had partial response and 2 had no change. The response rates were 74% (29/39) in the 2-cycle group and 94% (34/36) in the 4-cycle group. There were no progressive disease in these 2 groups. However a higher proportion of PR was observed in stage II patients than in stage III patients. Twelve of 36 patients underwent breast conserving surgery, as tumor size had become smaller and down-staging was realized after neoadjuvant chemotherapy. In addition, axillary lymph nodes were palpable in all 75 patients before neoadjuvant chemotherapy with the ET regimen. But 46% (18/39) in the 2-cycle group and 75% (27/36) in the 4-cycle group became impalpable. Conversely, major toxicities (including leukopenia and gastroenteric reactions) were similar in both groups, but myalgia, arthralgia, neurotoxicity and alopecia were more severe in the 4-cycle group than in the 2-cycle group. In the present study, neoadjuvant chemotherapy with a 4-cycle ET regimen was more effective than with a 2-cycle regimen in down staging locally advanced breast cancer. Although major toxicities were more severe in the 4-cycle group than in the 2-cycle group, the regimen was tolerable and safe.

Gemcitabine combined with cisplatin as first-line treatment in patients with epithelial ovarian cancer: a phase II study.

OBJECTIVE: This phase II study was performed to evaluate the activity and toxicity of gemcitabine plus cisplatin as first-line treatment of advanced epithelial ovarian cancer. METHODS: Chemonaive patients with histologically or cytologically confirmed FIGO stage III or IV epithelial ovarian carcinoma were enrolled. Patients received cisplatin 75 mg/m(2) on Day 1 and gemcitabine 1250 mg/m(2) on Days 1 (after cisplatin) and 8 of a 21-day cycle. RESULTS: Of the 42 female patients (median age 60 years) enrolled, 81% had a Zubrod performance status of 0 or 1. Among the 37 response-evaluable patients, there were 5 (13.5%) pathological complete responses (CRs), 16 (43.2%) pathological partial responses (PRs), and 3 (8.1%) clinical PRs, for an overall response rate of 64.9% (95% CI: 47.4-79.8%) and a pathological response rate of 56.8%. Per an intent-to-treat analysis, the overall response rate was 57.1% (95% CI: 41.0-72.3%). After a median follow-up time of 15.8 months, the median survival was 24.0 months and median progression-free survival was 13.4 months. Grade 3/4 neutropenia and thrombocytopenia occurred in 69.0 and 33.3% of patients, respectively, with no febrile neutropenia or hemorrhage. Grade 3/4 nausea and vomiting occurred in 35.7% and grade 3 alopecia in 21.4% of the patients. One patient died due to a toxicity-related death (dyspnea). CONCLUSIONS: Gemcitabine plus cisplatin is active and feasible as first-line treatment of advanced epithelial ovarian cancer. Further clinical trials adding gemcitabine to first-line treatment seem warranted.

Intensive chemoradiation followed by esophagectomy for squamous cell and adenocarcinoma of the esophagus.

PURPOSE: To determine the pathologic complete response rate, toxicity, and survival of patients with resectable squamous cell or adenocarcinoma of the esophagus treated with a 30-day preoperative chemoradiation regimen and surgical resection. PATIENTS AND METHODS: Fifty patients (16 squamous, 33 adeno, one undifferentiated) who had carcinoma of the esophagus (limited to the primary tumor and regional or celiac nodes) were treated with cisplatin 26 mg/m2/day continuous infusion days 1 through 5 and 26 through 30, 5-fluorouracil (5-FU) 300 mg/m2/day continuous infusion days 1 through 30, and radiation 44 Gy, 2 Gy/fx in 22 daily fractions, days 1 through 30, followed by esophagectomy. RESULTS: Forty-seven patients underwent esophagectomy (94% operability rate), and 45 had total gross removal of disease and negative margins of resection (90% resectability rate). Nineteen patients (40%) had a pathologic complete response (CR). Forty (80%) received 100% of the planned cisplatin dose, 29 (58%) received 100% of the planned 5-FU dose, and 40 (80%) received > or = 80% of the planned 5-FU dose. Forty-five (90%) received the planned 44-Gy radiation dose. Grade 3 or 4 neutropenia occurred in 60% of patients. The incidence of febrile neutropenia was 34%. There was one septic death during chemoradiation and no operative deaths. Weight loss requiring nutritional support occurred in 50% of patients, secondary to anorexia, dysphagia, and/or esophagitis. The survival of all registered patients at a median follow-up of 43 months was 2-year survival 58%, median 31.3 months. Survival analysis by histology showed no difference between the two histologic types (squamous vs adenocarcinoma). However, survival by pathologic response was significantly different: pathologic CR, 19 patients, 2-year survival 78%, median survival 58 months; and pathology positive, 28 patients, 2-year survival 46%, median survival 22.4 months. A Cox proportional hazards model and logistic regression analysis demonstrated a significant survival advantage for pathologic CRs and stage I disease versus higher-stage disease and a correlation between chemotherapy dose received and pathologic staging. DISCUSSION: This 30-day chemoradiation regimen followed by surgery resulted in a high pathologic complete response rate, 40%, and apparent survival advantage for this group. The median survival rate of 31.3 months and 2-year survival rate of 58% suggest that this regimen may improve survival over surgical treatment alone. Randomized trials with large accrual and statistical power are necessary to confirm our results and to determine optimal treatment.

Feasibility and toxicity of weekly Paclitaxel-Carboplatin in 131 patients with pretreated and non-pretreated solid tumors.

BACKGROUND: Chemotherapy with paclitaxel and carboplatin 3-weekly is active in many tumors. Major toxicities are myelosuppression and neurotoxicity. Weekly administration of taxanes allows high dose intensity with reduced toxicity. PATIENTS AND METHODS: 131 patients with solid tumors were treated as outpatients with paclitaxel 75 mg/m(2) and carboplatin AUC 2-3 days 1, 8, 15 every 4 weeks irrespective of pretreatment and partly in neoadjuvant and multimodal concepts. RESULTS: 125 patients (median age 58 years) were evaluable for response and toxicity, of whom 45 suffered esophageal carcinoma (19 patients in neoadjuvant treatment) and 31 non-small cell lung cancer. 49 patients were pretreated. 23 patients received concomitant radiotherapy of esophagus or lung in doses ranging from 40 to 60 Gy. We observed a low hematologic toxicity with 15.2% grade-III/IV leukopenia/granulocytopenia and 3.2% thrombocytopenia grade III/IV. Neurotoxicity grade II was reported in 14 patients. Main toxicity with radiotherapy was esophagitis grade II or III in 7 out of 23 patients. Overall response rate was 54.2%. 5 out of 19 patients treated neoadjuvantly for esophageal cancer reached a pathological complete response. CONCLUSIONS: Weekly paclitaxel and carboplatin is safe and feasible in outpatients and a high dose intensity can be achieved. The favorable toxicity profile allows treatment of elderly and pretreated patients. Response rate is high including pathological complete responses and responses appear quickly, making this therapy most suitable for multimodal and neoadjuvant treatments.

Neoadjuvant therapy with gemcitabine in breast cancer.

Primary systemic therapy (ie, preoperative or neoadjuvant) increases the possibility for breast-conserving surgery in patients with primary breast cancer. Patients with pathologic complete response to primary systemic therapy have improved survival compared with those with persistent tumors. Several phase II trials have evaluated gemcitabine-containing doublet or triplet regimens as primary systemic therapy for breast cancer, results of which have shown promising clinical and pathologic response rates with manageable toxicity. Results of a phase I/II study of gemcitabine (Gemzar)/epirubicin (Ellence)/docetaxel (Taxotere), or GEDoc, with prophylactic filgrastim (Neupogen), as primary systemic therapy in 77 evaluable patients with primary breast cancer are reported herein. Dose-limiting toxicities were grade 3 febrile neutropenia (n = 1) and grade 3 diarrhea (n = 2) at the fourth dose level of GEDoc tested (gemcitabine at 800 mg/m2 days 1 and 8, epirubicin at 90 mg/m2 day 1, and docetaxel at 75 mg/m2 day 1). As assessed by ultrasound, 92% of patients responded overall (22% complete response), and 79% of patients could undergo breast-conserving surgery. The pathologic complete response rate in resected breast tissue was 26%.

Paclitaxel, carboplatin, and long-term continuous 5-fluorouracil infusion in the treatment of upper aerodigestive malignancies: preliminary results of phase II trial.

We evaluated the efficacy and toxicity of a novel chemotherapy regimen that included paclitaxel (Taxol; Bristol-Myers Squibb Company, Princeton, NJ), carboplatin, and long-term, continuous-infusion 5-fluorouracil in the treatment of cancers of the upper aerodigestive tract. In the preoperative treatment of patients with localized esophageal cancer, we administered this regimen concurrently with radiation therapy. Thirty-eight patients with biopsy-proven cancers of the head and neck or esophagus entered this trial between January 1996 and November 1996. Patients with head and neck cancers considered curable with local treatment modalities were excluded. All patients received the following chemotherapy regimen: paclitaxel 200 mg/m2 via 1-hour intravenous infusion on days 1 and 21, carboplatin at an area under the concentration-time curve of 6.0 intravenously on days 1 and 21, and 5-fluorouracil 225 mg/m2/d via continuous infusion on days 1 to 42. Patients with localized esophageal cancer also received radiation therapy beginning on day 1 (1.8 Gy/d; total dose, 45 Gy). Patients were re-evaluated at week 6; responding patients received a repeat course of treatment, except for those with localized esophageal cancer, who underwent resection at week 10. Twenty-five of 29 evaluable patients had major responses to treatment. Four of five patients with locally advanced head and neck cancer had complete clinical responses, while eight of 11 patients with metastatic disease responded. All 13 evaluable patients with localized esophageal cancer underwent resection, and nine (69%) had a pathologic complete response. Toxicity was moderate, with brief grade 3/4 leukopenia occurring in 19 patients (66%). Esophagitis occurred in five of 13 patients receiving concurrent chemotherapy and radiation therapy, but was reversible and generally occurred during the last week of radiation therapy. Other grade 3/4 toxicity was uncommon. This novel regimen of paclitaxel, carboplatin, and long-term 5-fluorouracil infusion is feasible and highly active in patients with cancers of the upper aerodigestive tract. It can be used concurrently with radiation therapy before resection for localized esophageal cancer. The high overall response rates, and particularly the high pathologic complete response rates in resected patients with esophageal cancer, are encouraging and warrant further evaluation of this regimen.

Local excision of T2 and T3 rectal cancers after downstaging chemoradiation.

OBJECTIVE: To evaluate the safety and efficacy of local excision in patients with T2 and T3 distal rectal cancers that have been downstaged by preoperative chemoradiation. SUMMARY BACKGROUND DATA: T2 and T3 cancers treated by local excision alone are associated with unacceptably high recurrence rates. The authors hypothesized that preoperative chemoradiation might downstage both T2 and T3 lesions and significantly expand the indications for local excision. METHODS: Local excision was performed after preoperative chemoradiation on patients with a complete clinical response or on patients who were either ineligible for or refused to undergo abdominoperineal resection. Local excision was approached transanally by removing full-thickness rectal wall and the underlying mesorectum. RESULTS: From 1994 to 2000, 95 patients with rectal cancers underwent preoperative chemoradiation and surgical resection for curative intent. Of these, 26 patients (28%), 19 men and 7 women, with a mean age of 63 years (range 44-90), underwent local excision. Pretreatment endoscopic ultrasound classifications included 5 T2N0, 13 T3N0, 7 T3N1, and 1 not done. Pathologic partial and complete responses were achieved in 9 of 26 (35%) and 17 of 26 (65%) patients, respectively. Two of nine partial responders underwent immediate abdominoperineal resection. The mean follow-up was 24 months (median 19, range 6-77). The only recurrence was in a patient who refused to undergo abdominoperineal resection after a partial response. There was one postoperative death from a stroke. This treatment was associated with a low rate of complications. CONCLUSION: Local excision appears to be an effective alternative treatment to radical surgical resection for a highly select subset of patients with T2 and T3 adenocarcinomas of the distal rectum who show a complete pathologic response to preoperative chemoradiation.

Induction chemoradiotherapy for advanced stage III non-small cell lung cancer: long-term follow-up in 42 patients.

This multi-institutional phase II study was designed to assess the feasibility, efficacy, toxicity, and long-term survival of induction chemoradiotherapy followed by surgery in previously untreated patients with advanced stage III non-small cell lung cancer. Chemotherapy regimen included cisplatin 20 mg/m2 on days 1-5 and 29-33, and VP-16 40 mg/m2 on days 1-5 and 29-33. Radiotherapy (50 Gy in 25 fractions) began on day 1. Clinically downstaged patients underwent thoracotomy 3-5 weeks after the completion of radiotherapy. Forty-two eligible patients (ten stage IIIA and 32 IIIB) were followed for a median period of 64 months. The response rate was 81%, and 20 patients had a clinically good response. Twenty-one patients underwent thoracotomy. Nineteen patients had complete resections and there were seven pathologic complete responses. There were four treatment related deaths (all stage IIIBs). There were significant survival differences between stage IIIA versus IIIB patients (P = 0.028; median survivals, 24.9 vs. 11.1 months; 5-year survival rates, 20% vs. 8.3%), and patients that achieved pathologic complete response (CR) versus those that did not (P = 0.045; median survivals 30.1 vs. 11.1 months; 5-year survival rates, 28.6% vs. 8.3%). Although the induction chemoradiotherapy employed in this study was not appropriate for stage IIIB patients, it proved feasible in stage IIIA patients in whom it resulted in good 5-year survival rates. It also provided good survival rates in patients achieving pathologic CR.
