Survival following intensive preoperative combined modality therapy with paclitaxel, cisplatin, 5-fluorouracil, and radiation in resectable esophageal carcinoma: a phase I report.

PURPOSE: To assess the benefits of aggressive chemoradiation therapy followed by surgery in resectable esophageal carcinoma. METHOD: Twenty-nine patients with resectable carcinoma were treated with 60 Gy of radiation (2 Gy daily for 6 weeks) and concurrent chemotherapy consisting of continuous infusion of 5-fluorouracil (200-225 mg/m(2)/d), paclitaxel (25, 40, 50, or 60 mg/m(2)) weekly over 1 hour, and cisplatin (25 mg/m(2)) weekly immediately following paclitaxel throughout radiation. Patients received either 4 cycles of postoperative paclitaxel 175 mg/m(2) over 3 hours and cisplatin 75 mg/m(2) every 3 weeks or paclitaxel 175 mg/m(2) over 3 hours and cisplatin 75 mg/m(2) every 3 weeks prior to the initiation of chemoradiation. After induction therapy and restaging, esophagectomy was performed 4 to 6 weeks later. RESULTS: Twenty-seven patients were eligible for study (26 men, 23 with adenocarcinoma). Median age was 58 years (range 30-73). The maximum tolerated dose combination was paclitaxel 50 mg/m(2) over 1 hour weekly, cisplatin 25 mg/m(2) over 1 hour weekly, 5-fluorouracil 200 mg/m(2)/d by continuous infusion throughout radiotherapy and radiation to 60 Gy. Twenty-two patients completed therapy and underwent surgical resection. Four patients had complete pathological responses and 18 had partial responses with no mortality. The commonest dose-limiting toxicity was mucositis and esophagitis (n = 7). Median follow-up of 27 patients was 150 weeks (range 7-303). At 2-year follow-up 16/27 (59%) were alive and 15/27 (56%) were free of disease. At 4-year follow-up 12/27 (44%) were alive and free of disease. Median follow-up of 22 patients undergoing esophagectomy was 205 weeks (range 26-303). At 4-year follow-up 10/22 (45%) were alive and free of disease. For the 18 patients treated at or above the maximum tolerated dose, median follow-up was 151 weeks (range 35-206) and at 3-year follow-up 9/18 (50%) were alive and free of disease. CONCLUSION: Aggressive combined modality therapy of esophageal carcinoma was associated with excellent long-term survival in this phase I trial.

Combined modality therapy in non-small cell lung cancer.

Lung cancer kills more Americans annually than the next four most frequently diagnosed malignancies combined. Single-modality therapy is the standard for most cases of limited and metastatic non-small cell lung cancer, but treatment of locally advanced disease remains controversial. Historically, radiotherapy alone was used; more recent approaches include single-agent or combination chemotherapy. The combined chemoradiotherapy approach, versus single-modality chemotherapy or irradiation, has improved on survival. Investigators have also recently shown an advantage to adding chemotherapy with or without radiotherapy to definitive surgery. Better staging systems and definitions of biologic prognostic factors may help determine the optimal therapy for locally advanced non-small cell lung cancer patients.

Long-term follow-up of Ewing's sarcoma of bone treated with combined modality therapy.

Between 1968 and 1980, 107 consecutive patients with Ewing's sarcoma of bone were entered on three sequential combined modality treatment protocols (S2, S3, S4) at the National Cancer Institute (NCI). Protocol treatment involved 4 cycles of two drug [cyclophosphamide (CTX) and vincristine (VCR)] or three drug [CTX and VCR with either actinomycin-D (ACT-D) or doxorubicin (ADR)] regimens and local irradiation (50 Gy) to the involved bone. Eighty patients presented with localized disease and 27 patients had metastatic disease at presentation, including 11 patients with multiple metastatic sites. With a median potential follow-up of greater than 15 yrs (range 8-20 yrs), 28 pts (27%) remain alive. Disease-free (DFS) and overall survival (OS) decreased most rapidly during the initial 5 yrs of follow-up with 5-yr DFS of 29% and 5-yr OS of 39%. Only two patients with metastases at presentation are long term (greater than 5 yr) survivors. For localized disease patients, the 2, 5, 10, and 15 yr DFS and OS are 52%, 37%, 35%, and 33% DFS and 68%, 51%, 39%, and 34% OS, respectively. Eleven patients relapsed locally as the first site of failure. Using the Cox proportional hazards model, four significant variables for both DFS and OS were recognized, including metastatic disease at presentation, age greater than 25 yrs, high LDH in localized disease patients, and central primary tumor in localized disease patients in decreasing order of significance. We conclude that a majority of these patients with Ewing's sarcoma of bone relapsed within 5 yrs of presentation although late relapse (5-15 yrs) did occur. Local failure occurred in 20% of patients using these combined modality treatments but had no impact on overall survival.

Intensive combined-modality therapy in small cell lung cancer.

Combination ifosfamide/carboplatin/etoposide (ICE) chemotherapy and ICE plus mid-cycle vincristine (VICE) are reviewed. Thoracic radiotherapy and prophylactic cranial irradiation given as single fractions in the majority of patients have been intercalated with VICE in the later studies. The patient populations have not been intensively staged with computed tomography, etc, but do have reasonable Karnofsky performance status ratings and biochemical screens. A policy of no dose reduction over six courses of VICE chemotherapy has been followed in three consecutive studies of 166 patients. The minimum length of follow-up is 26 months and the 2-year survival rate is > or = 30%. Hematopoietic growth factor support in an attempt to overcome the considerable myelosuppression with VICE therapy is currently being evaluated.

Combined-modality therapy with inhaled nitric oxide and exogenous surfactant in term infants with acute respiratory failure.

OBJECTIVE: To report cases of neonates successfully treated with both exogenous surfactant and inhaled nitric oxide (INO). DESIGN: Retrospective chart review of full term infants treated between January and May 1999 in the neonatal intensive care unit of The Children's Hospital at Strong, University of Rochester, Rochester, New York. PATIENTS: Three full-term infants treated with surfactant and INO were identified. Each infant had severe acute respiratory failure (as a result of severe aspiration syndromes) and a clinical diagnosis of pulmonary hypertension and parenchymal lung disease in the absence of congenital malformations. INTERVENTIONS: One infant received INO (20-40 ppm) followed by exogenous surfactant (100mg/kg); the other two received surfactant followed by INO. MAIN RESULTS: All three infants exhibited a favorable response to treatment with these agents in terms of improved arterial oxygenation as summarized by oxygenation index and all survived to discharge home without referral for extracorporeal membrane oxygenation. CONCLUSIONS: No adverse interactions were observed related to INO plus surfactant therapy. The responses of these critically ill infants were consistent with the hypothesis that the actions of INO in dilating the pulmonary microvasculature and of exogenous surfactant in stabilizing and recruiting alveoli are complementary and may lead to additive clinical benefits. These case results suggest that more extensive clinical studies are warranted for combined-modality therapy with INO and exogenous surfactant in patients with the acute respiratory distress syndrome.

Chemotherapy for recurrent disease and combined modality therapies for head and neck cancer.

The identification and development of new agents and innovative treatment approaches remain a priority. The prognosis for patients with recurrent or metastatic head and neck cancer remains poor; thus participation in trials of promising investigational agents is an important option for these individuals. For patients with locally advanced tumors, combined modality treatment is undergoing rapid evolution. The optimal combination and sequence of therapies have yet to be determined. However, available data support an increasing role for chemotherapy especially as part of strategies to preserve organ function and treat unresectable disease.

Intensive combined modality therapy including low-dose TBI in high-risk Ewing's Sarcoma Patients.

Twenty-four high-risk Ewing's sarcoma patients were treatedf on an intensive combined modality protocol including low-dose fractionated total body irradiation (TBI) and autologous bone marrow infusion (ABMI). Twenty patients (83%) achieved a complete clinical response to the primary and/or metastatic sites following induction therapy. The median disease-free interval was 18 months, and nine patients remain disease-free with a follow-up of 22 to 72 months. Local failure as a manifestation of initial relapse occurred in only three patients (15%), each having synchronous distant failure. Eight patients failed initially with only distant metastases, usually within 1-2 years following a complete clinical response. Two patients with a single metastasis were again rendered disease-free and remain free from second relapse with 18 and 30 months follow-up. No other relapsed patient was able to be rendered disease-free, and most died of progressive disease within 6 to 12 months of relapse. Two patterns of granulocyte recovery following consolidative therapy (include TBI) and ABMI were recognized. Seventeen patients reached a total granulocyte count of >500 cells/mm3 within 4 weeks of ABMI (early graulocyte recovery), while seven patients required >4 weeks from ABMI (late granulocyte recovery). The time of platelet recovery (>50,000/mm3) was different for the groups with early and late granulocyte recovery (25 days vs. 54 days, p <.001). Six of seven patients with late granulocyte recovery received locl high-dose irratiation to >1/2 pelvis prior to bone marrow storage. Patients with late recovery did not tolerate maintenance chemotherapy. However, there was no difference in disease-free and overall survival, when compaing the groups with early and late granulocyte recovery. We conclude that these high-risk Ewing's sarcoma patients remain a poor-prognosis group in spite of intensive combined modality therapy include low-dose TBI. The control of microscopic systemic disease remains the major challenge to improving the cure rate. A new combined modality protocol with high-dose 'therapeutic' TBI (800 rad/2 fractions) is being used and the protocol design is outlined.

A phase II trial of preoperative combined-modality therapy for localized esophageal carcinoma: initial results.

OBJECTIVE: We sought to evaluate treatment response to a novel combined-modality treatment regimen for localized esophageal carcinoma. METHODS: Localized esophageal carcinoma was confirmed with endoscopic ultrasonography, computed tomography, and positron emission tomography before induction therapy. This therapy consisted of combined cisplatin/paclitaxel (cisplatin, 75 mg/m(2); paclitaxel, 175 mg/m(2); 2 cycles, 3-hour infusion) for weeks 1 and 4, combined cisplatin (30 mg. m(-2). wk(-1)) and paclitaxel (30-80 mg. m(-2). wk(-1), 96-hour infusion) with concurrent radiation (external beam, 1.8 Gy/d; total, 50.4 Gy) for weeks 7 to 12, and esophagectomy for week 16 after restaging confirmed resectability. RESULTS: Forty-one patients (36 men) with adenocarcinoma (n = 25) or squamous cell carcinoma (n = 16) were enrolled. Thirty-six patients completed treatment, of whom 34 (85%) had locally advanced disease of clinical stage T3-4 N0-1. Symptoms resolved or improved in 35 (92%) of 38 patients after induction chemotherapy. Fourteen (35%) and 10 (24%) patients experienced grade III/IV myelosuppression during induction chemotherapy and chemoradiation, respectively. Two (5%) had grade III and none had grade IV esophagitis during chemoradiation. Only 2 (5%) patients required enteral feeding-tube support during therapy. Of 33 R0 resections, 9 (26%) had complete pathologic disease, and 4 (12%) had microscopic residual disease. Major (eg, anastomotic response, delayed stricture, and respiratory failure) postoperative morbidity occurred in 13 (36%) of 36 patients. Operative mortality was 5.5% (2/36). CONCLUSION: This regimen of induction concurrent chemoradiation followed by surgical intervention for esophageal carcinoma produces rapid dysphagia relief with initial chemotherapy, has a high overall response rate, and has acceptable toxicity levels.

Therapeutic strategies for combined-modality therapy of locally advanced non-small-cell lung cancer: rationale for consolidation docetaxel therapy.

Currently, there is no accepted standard of care for locally advanced and surgically unresectable non-small-cell lung cancer. Typically, treatment for patients with good performance status consists of a combination of chemotherapy and thoracic radiation therapy (RT), but the integration of these modalities and the respective dose schedules vary considerably. Herein, we review the rationale for a treatment paradigm employing consolidation docetaxel therapy after concurrent chemotherapy/RT and the results of recent clinical trials using this approach.

Combined modality therapy with bleomycin, hyperthermia, and radiation.

In an attempt to develop better combination therapies for use with local radiation, the interaction between bleomycin and hyperthermia +/- radiation was studied in the FSaIIC tumor system. In cells exposed in vitro to bleomycin at 37 degrees C and at pH 7.40, the drug was substantially more toxic toward normally oxygenated than hypoxic cells. At hyperthermic temperatures (42 degrees or 43 degrees C), however, the differential killing between the normally oxygenated and hypoxic cells disappeared and bleomycin became significantly more toxic. Exposure to bleomycin at pH 6.45 did not substantially alter the cytotoxicity of the drug at 42 degrees or 43 degrees C. In tumor growth delay experiments, combining bleomycin, hyperthermia, and radiation induced long delays, and the more successful sequences were bleomycin----radiation----hyperthermia or bleomycin----hyperthermia----radiation. If radiation was given prior to drug and hyperthermia, however, the sequence was significantly less effective. In tumor excision experiments performed 24 h after treatment, increasing doses of bleomycin produced a shallow, log-linear increase in tumor cell kill at 37 degrees C, but bleomycin followed by hyperthermia (43 degrees C, 30 min) led to about 1 log more cell killing. Administration of bleomycin just prior to treatment with a single dose of radiation was cytotoxically additive. In this assay the most effective trimodality treatment sequence was bleomycin----hyperthermia----radiation. In tumor subpopulations defined by Hoechst 33342 dye staining, bleomycin at 37 degrees C was about two-fold more toxic toward the bright (presumably well-oxygenated) cells than toward the dim (presumably hypoxic) cell subpopulation. The addition of hyperthermia following bleomycin produced nearly a log more tumor cell killing in both the bright and dim tumor cells. The combination of bleomycin followed by hyperthermia and then radiation was at least additive in the bright cells and caused a large cell kill, but in comparison, there was marked sparing of the dim cells. These results indicate that treatment with bleomycin and hyperthermia in conjunction with radiation can add substantially to tumor cell killing. This combination is significantly less effective in the hypoxic than oxic tumor regions, however, in spite of in vitro data which demonstrate that the cytotoxicity of bleomycin at hyperthermic temperatures is not oxygen-dependent.

Combined modality therapy of locally advanced breast cancer. One institution's experience and a review of the literature.

Fourteen patients with locally advanced breast cancer were treated at Stanford University Medical Center with a combined modality approach. Treatment consisted of an initial 5 day course of cyclophosphamide followed by three cycles of combination chemotherapy (CAF or CMF). Patients subsequently received radiation therapy to the involved breast and regional nodal areas, followed by mastectomy if resistant disease was present following irradiation. Additional chemotherapy (CMF) was administered for 6 cycles. With a median follow up of 42 months, all fourteen patients are free of local disease. Five out of the fourteen patients have experienced distant relapses and two patients died. We conclude that an aggressive combined modality approach to treatment of locally advanced breast cancer can result in excellent local control and survival even in poor prognosis patients. A review of pertinent studies on multimodality treatment for locally advanced breast cancer confirms our findings.
