BACKGROUND AND PURPOSE: While bronchial intraluminal irradiation is valued highly as a useful palliative treatment for lung cancer, its role as a curative treatment is unclear. The treatment results of 40 localized enbobronchial tumors (including tracheal cancer) who underwent external beam irradiation (EBR) and intraluminal irradiation (IR) as a curative treatment is reported, and the role of combined EBR and IR as a curative potential treatment is examined. MATERIALS AND METHODS: Forty patients, including 22 with roentgenographically occult lung cancer (ROLC), 14 (18 lesions) with postoperative recurrent lung cancer (PORLC) and four with tracheal cancer, who underwent EBR and IR from February 1987 to August 1996, were studied. IR was conducted using low dose rate (1.48 GBq) (192)Ir thin wires at a bronchial mucosal dose of 4-6 Gy per fraction, with a total dose of 10-57 Gy (median 28 Gy). All patients were also given combined external Linac X-ray irradiation for a total dose of 30-77 Gy (median 52 Gy). RESULTS: As for the primary effect, complete response (CR) was obtained in all 22 ROLC cases; CR was obtained in 12 (16 lesions), partial response (PR) in one and minor response (MR) in one of the PORLC cases; and CR was obtained in three and PR in one of the tracheal cancer cases. The 3-year and 5-year local control rate by Kaplan-Meier method was 75 and 65%, respectively. Twenty-two patients survived for 3 years or longer. Complications included one case each of fatal tracheal hemorrhage, bronchial mucosal ulcer and bronchial stenosis. CONCLUSIONS: Combined EBR and IR is useful as a curative potential treatment, and long-term survival can be expected in ROLC, tracheal cancer and a portion of PORLC cases.  相似文献

Radiotherapy in the management of cutaneous epidemic Kaposi's sarcoma   总被引:1,自引:0,他引:1  
Between June 1986 and December 1988, we treated 149 patients who had AIDS-related epidemic Kaposi's sarcoma with cutaneous irradiation. According to Mitsayasu's staging, 34 patients (23%) had Stage I disease, 82 (55%) Stage II, 0 Stage III, and 33 (22%) Stage IV. Fifty-eight patients (39%) had previously presented with one or more opportunistic infections. Ninety-four patients (63%) had received previous treatment of their Kaposi's sarcoma: 85 (57%) with interferon and 43 (29%) with vinblastine. Among the 149 patients, we treated 88 (59%) with extended cutaneous irradiation using 4- and/or 8-MeV electron beam energy and 61 patients (41%) with localized irradiation using 45-kVp x-ray energy. The total prescribed dose was 30 Gy: 20 Gy in 2 weeks (2.5 Gy/fraction, 4 times/week), followed by 2 weeks of no irradiation, and then 10 Gy in one week by the same dose schedule. Twenty patients (13%) with edema of the lower limbs were treated using 4-Mv photon therapy with bolus. Of the 131 evaluable patients, 63% achieved a complete remission (CR) and 30% a partial remission (PR) after a mean period of 1.5 months (range: 0.5-3 months). The clinical disease stage, anatomic site, and irradiation technique did not significantly influence the remission rates, although we noticed a higher CR rate when localized irradiation was used (71% vs 55.5% for localized and extended irradiation, respectively; p = 0.08). The overall tolerance was acceptable. Complications were severe epidermitis with skin ulcerations (8% of patients), exudative epidermitis (26%), dry epidermitis (60%), and varying degrees of erythema (6%). Of the 87 patients whose AIDS remained relatively clinically stable during the observation period, recurrences occurred in 56 (64%) after an average of 5.5 months (range: 1.5-12 months). We conclude that radiotherapy is useful and can be recommended as a palliative treatment to relieve pain and physical discomfort or to achieve cosmetic improvements for patients with epidemic Kaposi's sarcoma. We also conclude that radiotherapy is most beneficial in the early stages of disease, when localized treatment is practical.  相似文献

Objective: To study the toxicities and efficacy of concurrent gemcitabine plus cisplatin combined with three-dimensional conformal radiotherapy for stage Ⅲ non-small cell lung cancer (NSCLC). Methods: Thirty-six patients with pathologically diagnosed NSCLC received radiotherapy and concurrent chemotherapy. There were 22 patients with stage llla and 14 patients with lllb. Radiotherapy was given a total of 60-70 Gy in conventional fractionation. Chemotherapy included gemcitabine (600 mg/m2) and cisplatin (20 mg/m2), once per week. Results: Thirty-two patients received a total dose of 60-72 Gy. Two patients received 56 Gy and another two patients received 58 Gy. Thirty-four patients received 4-6 weeks of chemotherapy, while two patients received only 2 weeks of chemotherapy. The overall response rate (CR + PR), complete response rate (CR), partially response rate (PR) were 63.3% (30/36), 11.1% (4/36) and 72.2% (26/36) respectively. The median follow-up duration was 18.4 months. The 1-and 2-year overall survival rates were 77.8% (28/36) and 55.6% (20/36),respectively. Conclusion: Concurrent gemcitabine and cisplatin combined with three-dimensional conformal radiotherapy for stage Ⅲ non-small cell lung cancer is effective and well tolerated. Lone-term results need further study.  相似文献

Objective: To observe the recently therapeutic effects and toxicity of three-dimensional conformal radiotherapy combined with whole brain irradiation for patients with brain metastasis. Methods: 33 cases were treated by whole brain irradiation at first, the dose of which was 36-40 Gy (18-20 f). Then three-dimensional conformal radiotherapy was added to the focus with a total dose of 20-25 Gy, whose fractionated dose was 2-5 Gy/time, 5 times/week or 3 times/week. Results: Within 1 month after radiotherapy, according to imaging of the brain, the CR of all patients was 45.5%, PR 36.4%, NC 15.1%, and PD 3%. For the 32 cases with neural symptoms before radiation, the CR of the symptoms was 40.6% and PR 59.4%. All patients gained different increases in KPS grade. By the end of the follow-up period, there were 22 deaths with the mean survival time up to 9.3 months. Conclusion: Three-dimensional conformal radiotherapy combined with whole brain irradiation can not only effectively control brain metastases and improve life quality, but also tends to prolong survival time.  相似文献

5-FU increased the effect of irradiation therapy for cancer. TS-1 is an induced type of 5-FU, so it is also thought to enhance the effect of irradiation therapy for cancer patients. We conducted initial irradiation and TS-1 therapy for stage II to IV for 21 patients. 18 patients were clear this therapy. TS-1 was given at 80 to 100 mg/body/day for 4 weeks. The results were stage II CR 100%, stage III CR 100%, stage IV CR 14% and PR 86%. It was thought that irradiation with TS-1 combination therapy was effective and taking TS-1 was better than injecting patients with anticancer drug for quality of life (QOL).  相似文献

A total of 166 patients with non-small cell lung cancer (NSCLC) were included in two multicenter trials testing different treatment regimens. In study I, 116 patients received 4 cycles of aggressive polychemotherapy consisting of cis-platinum 100 mg/m2 (day 1), etoposide 100 mg/m2 (days 4-6), and vindesine 3 mg/m2 (day 1) (CEV); patients without distant metastases subsequently received chest irradiation with 50 Gy. In study II, 50 patients were treated with monochemotherapy consisting of etoposide 250 mg/m2 (days 1-3), and ifosfamide 5 g/m2 as 24-h infusion (day 29). While this program was repeated in responders with extensive disease (ED), patients with limited disease (LD) subsequently received chest irradiation with 50 Gy using 20 mg/m2 cis-platinum weekly as a radiosensitizer. Response rates (CR + PR) to chemotherapy were higher in study I than in study II, and were 26% (CR 3%) vs. 8% (CR 0%) for all patients, 18% (CR 0%) vs. 4% (CR 0%) for ED, and 45% (CR 11%) vs. 13% (CR 0%) for LD. The increase in response rates by radiotherapy was marginal in study I (CR + PR 47%, CR 18%), but remarkable in study II (CR + PR 42%, CR 29%). While median survival was slightly longer in study I than in study II for ED (7.7 vs. 6.6 months) and LD (14.4 vs. 12.0 months), the 2-year survival rate was in favor of study II (10% vs. 25%). Toxicity was clearly more pronounced in study I, including 3 lethal complications and 16 discontinuations of therapy due to side effects or refusal. Thus, while in ED the efficacy of both treatment regimens was very restricted, in LD radiotherapy with cis-platinum as a radiosensitizer achieved a relatively high 2-year survival rate which justifies further testing of this treatment strategy.  相似文献

OBJECTIVE: To evaluate radiotherapy dose and length of treatment in the control of early stage nasopharyngeal carcinoma (NPC) treated with a combination of external radiotherapy and brachytherapy, MATERIALS & METHODS: We reviewed the records of 133 patients with early stage nasopharyngeal carcinoma (stage I or II, AJC/UICC staging system) who received definitive radiotherapy in Chang Gung Memorial Hospital from 1979 to 1991. The median follow-up time was 7.1 years with a minimum of 2 years. All patients were treated with megavoltage external radiotherapy to the nasopharynx area (63-72 Gy) followed by high dose rate intracavitary brachytherapy (5-16.5 Gy in one to three fractions, spaced 1-2 weeks apart). The median total dose and time of irradiation was 75 Gy (69.8-81.4 Gy) and 11.6 weeks (7.8-20 weeks) respectively. Survival analysis was used to examine the effect of several variables on prognosis. RESULTS: The 5-year rates were 86.4% for local control, 84.7% for disease free survival, 88.5% for actuarial survival and 84.2% for overall survival. The treatment group (combination of time and dose of irradiation) was the most important prognostic factor according to Cox's proportional hazard model. Patients receiving radiation at a total dose of < or = 75 Gy completed in < 12 weeks showed the best prognosis. CONCLUSION: Treatment time and total treatment dose are both important factors in treating early stage NPC. Decreasing the total radiation time to < 12 weeks and not exceeding a radiation dose of 75 Gy gave the best results.   相似文献

Twenty-eight patients with oropharyngeal or hypopharyngeal carcinoma received concurrent chemoradiotherapy with CDDP or CDGP plus 5-FU between January 2001 and April 2006. The numbers of patients according to clinical stage were stage II:2; stage III:5; stage IVa:19 ; and stage IVb:2. Total radiation dose was 60-73.8 Gy (median 66 Gy) and overall treatment time was 41-57 days (median 47 days). Two courses of 5-FU 700 mg/m(2) on days 1-5 and CDDP or CDGP 70 mg/m(2) on day 4 were administered concurrently with radiotherapy. Median follow-up period was 26 months (range, 8-64 months).The incidences of grade 3 or greater acute toxicity were leukopenia 29%, anemia 21%, thrombocytopenia 7%, pharyngeal mucositis 43% and nausea 14%. No severe late toxicity was observed. Treatment responses of primary lesions were CR in 24 patients (86%) and PR in 4 patients (14%). The two-year local control rate was 87% and the 2-year overall survival rate was 72%. Concurrent chemoradiotherapy with CDDP or CDGP plus 5-FU seemed to be effective for advanced carcinomas of the oropharynx and hypopharynx.  相似文献

We have investigated the usefulness of combination therapy with radiation and HCFU for advanced and recurrent breast cancer according to a clinical controlled multicenter trial from 1982 to 1984. One hundred cases were registered and 82 of them were available. Treatment sites were the lymph nodes, skin, bone and lung, and the overall response rate was 58% in CR and 19% in PR, while the duration of remission was 18 weeks in CR. Side effects were found in 10% of the patients. Combination therapy with radiation and HCFU may be useful in multimodal treatment for advanced recurrent breast cancer.  相似文献

The survival and rate of chest infield relapse was examined in 48 patients with limited disease small cell lung cancer (LSCLC) who had achieved complete (CR) or partial response (PR) following three courses of chemotherapy. During 1985-1986 chemotherapy consisted of carboplatin and etoposide and during 1986-1987, of etoposide, carboplatin, cyclophosphamide, and vincristine (ECCO). After three courses of chemotherapy, chest irradiation (50 Gy in 25 fractions over 5 weeks) was given to encompass the original tumor volume. Complete responders were also given prophylactic cranial irradiation, 30 Gy in 10 fractions over 2 weeks. Overall median survival of all patients receiving chest irradiation was 17 months from commencement of radiotherapy. The infield relapse-free survival at 24 months was 49% (95% confidence interval: 32-66%). Patients who had only achieved a PR at the time of irradiation were more likely to relapse in the chest than complete responders (p = 0.09). We conclude that local relapse remains a major cause of failure in patients with LSCLC in spite of sequential high dose radiotherapy given to patients who have responded to chemotherapy.  相似文献

The increasing number of HIV-infected patients makes palliative treatment of HIV-associated Kaposi's sarcoma more common. We retrospectively evaluated a reduced fractionated radiotherapy with 20 Gy in respect to response rates and acute side-effects. From January 1992 to January 1995, 52 patients with HIV-associated Kaposi's sarcoma were treated with 133 single portals. Six weeks after the end of radiotherapy 42 patients with 124 portals were evaluable with respect to response rates and side-effects. Of the treated portals 32% were judged as complete responses (CR), 55% as partial responses (PR) and 12% as no change (NC). Skin reactions RTOG, grade I were seen in 74% of the patients. Compared with literature data the reduced overall dose of 20 Gy in 10 fractions led to a reduction of CRs by approximately 50% while the overall response rate remained equal. The success of radiotherapy for the nodular component of Kaposi's sarcoma can be improved, if a dose exceeding 20 Gy in 10 fractions is applied but at the cost of increasing side-effects in case that non-conventional fractionation schemes are used.  相似文献

PURPOSE: Therapeutic results were analyzed in 39 patients with roentgenographically occult lung cancer (ROLC), and the significance and optimal dose of this therapy were evaluated. METHODS AND MATERIALS: The subjects were 39 patients who underwent intraluminal irradiation between May 1987 and August 1999. Radiotherapy was performed by combining external irradiation with intraluminal irradiation using middle-dose-rate iridium (four 370-MBq wires) through a catheter with a spacer, which held the source in the center of the bronchus. The doses of radiation were 22-66 Gy (median value 45 Gy) by external irradiation and 10-46 Gy (median value 28 Gy) by intraluminal irradiation. RESULTS: The therapeutic effect was CR in 38 patients and PR in 1, and local recurrence was observed in a PR case and 3 of the 38 patients who showed CR. The 3-year and 5-year relapse-free survival rates were both 87%. No severe radiation injury was observed. CONCLUSIONS: Considering that ROLC often occurs as multiple cancers and that many patients with ROLC have reduced lung function, radiation therapy by a combination of intraluminal irradiation and external irradiation is expected to replace surgery as the first choice for the treatment of this disease in the twenty-first century.  相似文献
