This study investigated the maximum tolerated dose (MTD) of S-1 with concurrent radiotherapy in patients with head and neck cancer, based on the frequency of dose-limiting toxicities (DLT). S-1 was administered orally at escalating doses from 40 mg/m2 b.i.d. on the days of delivering radiotherapy, which was given at a total dose of 64–70 Gy in 32–35 fractions over 6–7 weeks. A total of 12 patients (3 patients at 40 mg/m2, 6 patients at 60 mg/m2, and 3 patients at 80 mg/m2) were enrolled in this trial. At the dose of 80 mg/m2, two of the three patients developed DLT (Grade 3 anorexia and rhabdomyolysis) due to S-1, so the MTD was determined to be 80 mg/m2. Among the 12 enrolled patients, 9 (75%) showed a complete response and 3 (25%) showed a partial response. The overall response rate was 100%. The recommended dose of S-1 with concurrent radiotherapy is 60 mg/m2.  相似文献

In Japan, cetuximab with concurrent bioradiotherapy (BRT) for squamous cell carcinoma of head and neck (SCCHN) was approved in December 2012. We herein report our initial experience of BRT, with special emphasis on acute toxicities of this combination therapy. Thirty-one non-metastatic SCCHN patients who underwent BRT using cetuximab between July 2013 and June 2014 were retrospectively evaluated. All patients received cetuximab with a loading dose of 400 mg/m2 one week before the start of radiotherapy, followed by 250 mg/m2 per week during radiotherapy. The median cycle of cetuximab was seven cycles and the median dose of radiotherapy was 70 Gy. Twenty-five patients (80.6%) accomplished planned radiotherapy and six cycles or more cetuximab administration. Six patients (19.4%) discontinued cetuximab. Grade 3 dermatitis, mucositis and infusion reaction occurred in 19.4%, 48.3% and 3.2%, respectively. One patient experienced Grade 3 gastrointestinal bleeding caused by diverticular hemorrhage during BRT. Grade 3 drug-induced pneumonitis occurred in two patients. The response rate was 74%, including 55% with a complete response. BRT using cetuximab for Japanese patients with SCCHN was feasible as an alternative for cisplatin-based concurrent chemoradiation, although longer follow-up is necessary to evaluate late toxicities.  相似文献

PURPOSE: Cough is a common symptom in advanced cancer. The use of hydrocodone as an antitussive has not been studied previously in this setting. This study evaluates hydrocodone for cough in advanced cancer METHODS: The results presented are from a phase II study with dose titration. Setting: Palliative medicine program in a tertiary referral center PATIENTS: 25 consecutive patients with cough from irreversible causes, on a stable opioid regimen for the prior 24 hours, and no previous or current use of hydrocodone for cough. INTERVENTION: 5 mg hydrocodone was administered twice daily. The dose was then titrated daily (maximum: 60 mg/24 h), if needed, until a > or = 50 percent improvement of the frequency of cough was achieved and then maintained for three consecutive days. MEASUREMENTS: Cough severity, frequency, complications, and hydrocodone side effects. RESULTS: 20 persons (10 women and 10 men) completed study evaluation. Median age was 63 years (range: 42-82). Nine patients had lung cancer and seven had lung or pleura metastases; 19 patients had at least 50 percent improvement of their cough frequency. The median best response was 70 percent improvement in the cough frequency (range: 50-90 percent). Median hydrocodone dose associated with the best response was 10 mg/day (range: 5-30 mg/day). Cough severity, frequency, associated symptoms and complications, and activities of daily living improved significantly. Side effects of hydrocodone (dry mouth, nausea, and drowsiness) were tolerable and rated as mild. CONCLUSIONS: Hydrocodone is effective and safe to treat cough in advanced cancer A starting dose of 10 mg per day in divided doses seems effective. Dose escalation may be required. Most improved within one day.  相似文献

The purpose of this study was to analyze the clinical outcomes of simultaneous modulated accelerated radiotherapy (SMART) in patients with nasopharyngeal carcinoma (NPC). A total of 97 patients who underwent SMART for NPC between August 2005 and November 2011 were evaluated. The prescribed dose was 69.9 Gy/30 fractions at 2.33 Gy/fraction to the primary gross tumor volume (PGTV) including the nasopharynx gross target volume and the positive neck lymph nodes, and 60 Gy/30 fraction at 2.0 Gy/fraction to the PCTV1; 54 Gy/30 fractions at 1.8 Gy/fraction was given to the PCTV2. Among 59 patients with local advanced disease, 31 patients received concurrent chemoradiotherapy (chemo-RT) with a regimen consisting of 135 mg/m2 paclitaxel on Day 1 and 25 mg/m2 cisplatin on Days 1–3. The median follow-up period was 42 months. The local control rate (LCR), distant metastases-free survival (DMFS) and overall survival (OS) rates were 93.3%, 90.3% and 91.6% at 3 years, and 87.6%, 87.9% and 85.7% at 5 years, respectively. There was no significant difference in outcome with respect to these three indicators for Stage III and IV disease treated with/without concurrent chemoradiotherapy (P > 0.05). Acute toxicities included Grade 3 mucositis, skin desquamation, and leucopenia, which occurred in 78 (80.4%), 8 (8.2%), and 45 (46.4%) patients, respectively. No patient had a Grade 3–4 late toxicity. SMART was associated with a favorable outcome for NPC with acceptable toxicity. The local-regional control was excellent but distant metastasis remains the main risk. The combination of SMART and chemotherapy needs to be optimized through further studies to enhance outcomes for locally advanced diseases.  相似文献

Rectal lymphogranuloma venereum (LGV) has reemerged as a sexually transmitted infection among men who have sex with men (MSM), particularly those who are HIV-positive. We undertook a systematic review and meta-analysis to determine the efficacy of doxycycline (100 mg 2×/d for 21 days) for rectal LGV in MSM. Nine studies were included: 4 prospective, 4 retrospective, and 1 combined retrospective and prospective. In total, 282 MSM with rectal LGV were included in the studies. All studies reported using nucleic acid amplification tests to assess microbial cure. Most patients (>80%) had symptomatic rectal infection. The fixed-effects pooled efficacy for doxycycline was 98.5% (95% CI 96.3%–100%, I2 = 0%; p = 0.993). Doxycycline at 100 mg twice daily for 21 days demonstrated a high microbial cure rate. These data support doxycycline at this dosage and duration as first-line therapy for rectal LGV in MSM.  相似文献

Preoperative chemoradiotherapy with capecitabine or 5-fluorouracil is a standard treatment for locally advanced rectal cancer (LARC). S-1, a prodrug of 5-fluorouracil, is a candidate for this chemoradiotherapy regimen in Japan; however, treatment outcomes after S-1 treatment alone are not clear. This study aimed to assess the efficacy and tolerability of preoperative chemoradiotherapy with S-1 alone for LARC. We retrospectively evaluated 54 LARC patients who underwent preoperative chemoradiotherapy with S-1 alone in our institution between 2005 and 2017. The clinical tumor stage was cT2–3 in 31 patients and cT4 in 23 patients, and lymph node metastases were clinically evident in 31 patients. S-1, at a dose of 80 mg/m2/day, was orally administered during radiotherapy. A total dose of 45–50.4 Gy was delivered in 25–28 fractions (median: 50.4 Gy). Surgical resections were scheduled 6–10 weeks after chemoradiotherapy completion. The 3- and 5-year overall survival rates were 92.4 and 72.8%, respectively, with a median follow-up time of 51 months. The 3- and 5-year local control rates were 96.2 and 85.9%, respectively. A pathological complete response was observed in 7 patients (13.0%) at the time of surgery. Ten patients (18.5%) had grade 3 acute toxicities and 5 patients (9.3%) had grade 3 late toxicities. No grade 4 or 5 toxicities were observed. Preoperative chemoradiotherapy with S-1 alone followed by total mesorectal excision resulted in a low incidence of toxicities and comparable clinical results. Therefore, S-1 alone can be a treatment option for preoperative chemoradiotherapy in LARC patients.  相似文献

Background: Sodium selenite at high dose exerts antitumor effects and increases efficacy of cytostatic drugs in multiple preclinical malignancy models. We assessed the safety and efficacy of intravenous administered sodium selenite in cancer patients’ refractory to cytostatic drugs in a phase I trial. Patients received first line of chemotherapy following selenite treatment to investigate altered sensitivity to these drugs and preliminary assessment of any clinical benefits. Materials and Methods: Thirty-four patients with different therapy resistant tumors received iv sodium selenite daily for consecutive five days either for two weeks or four weeks. Each cohort consisted of at least three patients who received the same daily dose of selenite throughout the whole treatment. If 0/3 patients had dose-limiting toxicities (DLTs), the study proceeded to the next dose-level. If 2/3 had DLT, the dose was considered too high and if 1/3 had DLT, three more patients were included. Dose-escalation continued until the maximum tolerated dose (MTD) was reached. MTD was defined as the highest dose-level on which 0/3 or 1/6 patients experienced DLT. The primary endpoint was safety, dose-limiting toxic effects and the MTD of sodium selenite. The secondary endpoint was primary response evaluation. Results and Conclusion: MTD was defined as 10.2 mg/m2, with a calculated median plasma half-life of 18.25 h. The maximum plasma concentration of selenium from a single dose of selenite increased in a nonlinear pattern. The most common adverse events were fatigue, nausea, and cramps in fingers and legs. DLTs were acute, of short duration and reversible. Biomarkers for organ functions indicated no major systemic toxicity. In conclusion, sodium selenite is safe and tolerable when administered up to 10.2 mg/m2 under current protocol. Further development of the study is underway to determine if prolonged infusions might be a more effective treatment strategy.  相似文献

Forty-eight patients successfully completed a six-week, double blind, placebo controlled trial of ranitidine hydrochloride 200mg twice daily for active duodenal ulceration. Following endoscopy 68% of the patients taking ranitidine had healed, compared to 35% of those who were taking placebo. Nineteen of the patients who had not healed then took a further six weeks of open active treatment; of these, 14 were successfully treated. Thirty-one of the patients who had healed duodenal ulcers then took ranitidine hydrochloride 100mg at night as a maintenance treatment for one year: 71% remained endoscopically and symptomatically in remission. No serious side effects were encountered.  相似文献

Ovulation inhibition by estetrol in an in vivo model   总被引:1,自引:0,他引:1  
BACKGROUND: Currently, the synthetic steroid ethinylestradiol (EE) is the preferred estrogen in combined oral contraceptives. The aim of the present study was to evaluate the effectiveness of the natural steroid estetrol (E(4)) as an ovulation inhibitor in rats when compared to EE. STUDY DESIGN: Regularly cycling female rats were treated orally twice daily for four consecutive days, starting on the day of estrus, with E(4) (0.03, 0.1, 0.3, 1.0 or 3.0 mg/kg), EE (0.0003, 0.001, 0.003, 0.01 or 0.03 mg/kg) or vehicle control (eight animals per group). In a second experiment conducted under the same experimental protocol, 2.0 mg/kg of E(4) was administered as a single daily dose or as a dose of 1.0 mg/kg twice daily. In both studies, the primary end point was the number of ovulated oocytes in the genital tract. RESULTS: Estetrol at the twice daily dose of 0.3 mg/kg and above inhibited ovulation. This effect was statistically significant (p<.05). The comparator, EE, significantly inhibited ovulation (p<.05) at the highest dose (0.03 mg/kg) administered twice daily. An E4 dose of 2.0 mg/kg administered once daily for four consecutive days inhibited ovulation in four of eight rats. In contrast, when the same dose was administered in two separate doses, that is, 1.0 mg/kg twice daily, ovulation was inhibited in eight of eight rats. The ED(50) for the EE and the E(4) dose response curves shows that EE is 18 times more potent than E(4). CONCLUSION: Twice daily administration of E(4) effectively inhibits ovulation in cycling rats. The effect is dose-dependent. The relative potency of E(4) is about 18 times less compared to that of EE. We conclude that based on these data, combined with available pharmacological and clinical data on the safety and efficacy of E(4), the human fetal estrogenic steroid estetrol is a potential candidate to replace EE in combined oral contraceptives.  相似文献

The purpose of this study was to examine the safety and feasibility of a novel protocol of neoadjuvant short-course hyperfractionated accelerated radiotherapy (SC-HART) combined with S-1 for locally advanced rectal cancer. A total of 56 patients with lower rectal cancer of cT3N1M0 (Stage III b) was treated with SC-HART followed by radical surgery, and were analyzed in the present study. SC-HART was performed with a dose of 2.5 Gy twice daily, with an interval of at least 6 hours between fractions, up to a total dose of 25 Gy (25 Gy in 10 fractions for 5 days) combined with S-1 for 10 days. Radical surgery was performed within three weeks following the end of the SC-HART. The median age was 64.6 (range, 39–85) years. The median follow-up term was 16.3 (range, 2–53) months. Of the 56 patients, 53 (94.4%) had no apparent adverse events before surgery; 55 (98.2%) completed the full course of neoadjuvant therapy, while one patient stopped chemotherapy because of Grade 3 gastrointestinal toxicity (CTCAE v.3). The sphincter preservation rate was 94.6%. Downstaging was observed in 45 patients (80.4%). Adjuvant chemotherapy was administered to 43 patients (76.8%). The local control rate, disease-free survival rate and disease-specific survival rate were 100%, 91.1% and 100%, respectively. To conclude, SC-HART combined with S-1 for locally advanced rectal cancer was well tolerated and produced good short-term outcomes. SC-HART therefore appeared to have a good feasibility for use in further clinical trials.  相似文献

OBJECTIVE: To evaluate the efficacy and safety of topiramate (TPM) for weight loss in healthy obese subjects. RESEARCH METHODS AND PROCEDURES: A randomized, double-blind, placebo-controlled, dose-ranging trial was conducted. Three hundred eighty-five subjects, 18 and 75 years of age, were randomized to receive either placebo or TPM at 64, 96, 192, or 384 mg daily. Dosing began at 16 mg once daily. In week 2, the dose was increased to 16 mg twice daily. Thereafter, the dose was raised every week by 32 mg/d (16 mg twice daily) until subjects reached their target dose. Twenty-four weeks after beginning treatment, all subjects were tapered off treatment by a dose reduction of 50% per week. All participants received the same lifestyle program. RESULTS: Mean percent weight loss from baseline to week 24 was -2.6% in placebo-treated patients vs. -5.0%, -4.8%, -6.3%, and -6.3% in the 64, 96, 192, and 384 mg/d TPM groups, respectively. Greater percentages of TPM-treated patients lost at least 5% or 10% of body weight compared with placebo. The most frequent adverse events were related to the central or peripheral nervous system, including paresthesia, somnolence, and difficulty with memory, concentration, and attention. Most events were dose-related, occurred early in treatment, and usually resolved spontaneously; only 21% receiving TPM withdrew due to adverse events compared with 11% on placebo. DISCUSSION: TPM produced significantly greater weight loss than placebo at all doses.  相似文献

The purpose of this study is to examine risk factors for late rectal toxicity for localized prostate cancer patients treated with helical tomotherapy (HT). The patient cohort of this retrospective study was composed of 241 patients treated with HT and followed up regularly. Toxicity levels were scored according to the Radiation Therapy Oncology Group grading scale. The clinical and dosimetric potential factors increasing the risk of late rectal toxicity, such as age, diabetes, anticoagulants, prior abdominal surgery, prescribed dose, maximum dose of the rectum, and the percentage of the rectum covered by 70 Gy (V70), 60 Gy (V60), 40 Gy (V40) and 20 Gy (V20) were compared between ≤ Grade 1 and ≥ Grade 2 toxicity groups using the Student''s t-test. Multivariable logistic regression analysis of the factors that appeared to be associated with the risk of late rectal toxicity (as determined by the Student''s t-test) was performed. The median follow-up time was 35 months. Late Grade 2–3 rectal toxicity was observed in 18 patients (7.4%). Age, the maximum dose of the rectum, V70 and V60 of the ≥ Grade 2 toxicity group were significantly higher than in those of the ≤ Grade 1 toxicity group (P = 0.00093, 0.048, 0.0030 and 0.0021, respectively). No factor was significant in the multivariable analysis. The result of this study indicates that the risk of late rectal toxicity correlates with the rectal volume exposed to high doses of HT for localized prostate cancer. Further follow-up and data accumulation may establish dose–volume modeling to predict rectal complications after HT.  相似文献

Curcumin has a potent antiproliferative activity and can also potentiate the antitumor effect of gemcitabine. This study was undertaken to evaluate the activity and feasibility of gemcitabine in combination with curcumin in patients with advanced pancreatic cancer. Seventeen patients were enrolled in the study and received 8,000 mg of curcumin by mouth daily, concurrently with gemcitabine 1,000 mg/m2 IV weekly × 3 of 4 wk; 5 patients (29%) discontinued curcumin after a few days to 2 wk due to intractable abdominal fullness or pain, and the dose of curcumin was reduced to 4,000 mg/day because of abdominal complaints in 2 other patients. One of 11 evaluable patients (9%) had partial response, 4 (36%) had stable disease, and 6 (55%) had tumor progression. Time to tumor progression was 1–12 mo (median 2½), and overall survival was 1–24 mo (median 5). Low compliance for curcumin at a dose of 8,000 mg/day, when taken together with systemic gemcitabine, may prevent the use of high doses of oral curcumin needed to achieve systemic effect. Further studies should be conducted to evaluate the ability of other formulations of curcumin to enhance the effect of chemotherapy in cancer patients.  相似文献
