Background:
We investigated the feasibility of dose-dense neoadjuvant chemotherapy (NACT) with paclitaxel and carboplatin before radical chemoradiation (CRT) and assessed the response rate to such a regimen.Methods:
CxII is a single-arm phase II trial of 46 patients, with locally advanced cervical cancer (stage Ib2-IVa). Patients received dose-dense carboplatin (AUC2) and paclitaxel (80 mg m−2) weekly for six cycles followed by CRT (40 mg m−2 of weekly cisplatin, 50.4 Gy, 28 fractions plus brachytherapy). The primary end point was response rate 12 weeks post-CRT.Results:
Baseline characteristics were: median age at diagnosis 43 years; 72% squamous, 22% adenocarcinoma and 7% adenosquamous histologies; FIGO stage IB2 (11%), II (50%), III (33%), IV (7%). Complete or partial response rate was 70% (95% CI: 54–82) post-NACT and 85% (95% CI: 71–94) post-CRT. The median follow-up was 39.1 months. Overall and progression-free survivals at 3 years were 67% (95% CI: 51–79) and 68% (95% CI: 51–79), respectively. Grade 3/4 toxicities were 20% during NACT (11% haematological, 9% non-haematological) and 52% during CRT (haematological: 41%, non-haematological: 22%).Conclusion:
A good response rate is achieved by dose-dense weekly NACT with carboplatin and paclitaxel followed by radical CRT. This treatment regimen is feasible as evidenced by the acceptable toxicity of NACT and by the high compliance to radiotherapy (98%). 相似文献2.

The objective of this study is to evaluate the efficacy and safety profile of the doxorubicin followed by cisplatin/docetaxel as primary chemotherapy for patients with locally advanced breast cancer (LABC). For this evaluation, 59 patients with LABC (T2–T4, N0–N2, M0) received three cycles of doxorubicin, followed by three cycles of cisplatin/docetaxel and followed by definitive surgery and locoregional radiotherapy with or without tamoxifen. The primary end point was pathologic complete response (pCR) in breast and axilla. Fifty-nine patients were evaluable for analysis: median age: 41 years, premenopausal: 68%, median tumor size: 6.0 cm (4–10), Stage IIB: 32% and IIIA/IIIB: 68%, both ER/PR positive: 53%, Her2/neu (3+) by IHC staining: 29%. Clinical complete response was seen in 44%, and clinical partial response was seen in 56%. Breast conserving surgery was performed in 44%, and MRM in 56%. pCR in the breast was 30.5%, in axilla was 37%, and pCR in both breast and axilla was 24%. Overall at follow-up of 60 months, the disease-free (DFS) and overall survival (OS) were 70 and 82%, respectively. The DFS and OS of patients who achieved complete pathologic response in breast and axilla were 78 and 100%, respectively, while 14 patients relapsed of which 46% were Her2 positive. Sequential combination of doxorubicin followed by docetaxel/cisplatin is a safe, feasible, and active combination, which offers the possibility of conservative surgery and is associated with high clinical and pathologic response rates, with promising and encouraging survival outcomes. 相似文献

PURPOSE: This study evaluated the toxicity and efficacy of docetaxel/capecitabine as neoadjuvant treatment for stage 2/3 breast cancer. EXPERIMENTAL DESIGN: Subjects with newly diagnosed invasive stage 2 and 3 breast cancer were eligible. The first cohort of patients was treated at dose A with neoadjuvant docetaxel (75 mg/m(2) i.v. day 1) and capecitabine (1000 mg/m(2) orally twice daily days 2-15) for four cycles. A second cohort of subjects was treated with a reduced dose, dose B, of docetaxel (60 mg/m(2) i.v. day 1) and capecitabine (937.5 mg/m(2) orally twice daily days 2-15). RESULTS: Thirty patients were enrolled. Eight of 10 patients treated at dose A required dose reductions of either docetaxel or capecitabine secondary to grade 3 or 4 toxicities: mucositis (1), hand-foot syndrome (3), diarrhea (2), perirectal abscess (1), and neutropenia (2). Because of a high rate of dose reductions, the next 20 patients were treated at dose B. The mean cumulative administered dose of docetaxel was 285 and 231 mg/m(2) at dose A and dose B, respectively. For capecitabine, the mean cumulative dose at dose A and B were similar at 1585 and 1627 mg/m(2)/day, respectively. The overall clinical response rate was 90% with 31% of patients having a complete response and 59% having a partial response. A pathological complete response in the breast was achieved in 10% of patients after four cycles of docetaxel/capecitabine. CONCLUSIONS: Docetaxel/capecitabine is a highly active regimen in the neoadjuvant setting. Neoadjuvant therapy with 75 mg/m(2) docetaxel and 1600 mg/m(2)/day days 2-15 is recommended. 相似文献

Background and purpose
We conducted a phase II study combining induction chemotherapy with continuous hyperfractionated accelerated radiotherapy (CHART) in locally advanced non-small-cell lung cancer (NSCLC).Materials and methods
A total of 40 patients with stage III NSCLC were enrolled. All patients received 3 cycles of chemotherapy followed by CHART (56 Gy in 36 fractions over 12 days). The primary outcome measure was radiation toxicity. Secondary endpoints were response rate, overall survival, disease-free survival and loco-regional progression-free survival.Results
Acute radiation toxicity was minimal and there were no significant late toxicities. The response rate after completion of chemoradiation was 65%. The median and 2-year overall survival, progression-free survival and loco-regional progression-free survivals were 15.7 months, 28%; 12.1 months, 23%; and 26.4 months, 51%, respectively.Conclusions
Induction chemotherapy can be safely combined with CHART. The survival results are consistent with previous studies of chemotherapy followed by accelerated radiotherapy. This approach should be compared with synchronous chemoradiation to determine if it represents a less toxic alternative. 相似文献6.

Purpose
Paclitaxel–cisplatin (TC) combination is effective and well tolerated in patients with unresectable gastric cancer. We investigated the efficacy and safety of TC for locally advanced gastric cancers in a neoadjuvant setting.Methods
Patients received 2–4 courses of paclitaxel (80 mg/m2) and cisplatin (25 mg/m2) on days 1, 8, and 15 in a 4-weekly schedule, followed by radical gastrectomy. Primary endpoint was the pathological response rate: percentage of tumors in which one-third or more parts were affected.Results
All 52 patients enrolled were eligible. Thirty-six (69.7 %) patients completed two or more courses of chemotherapy. Forty-three patients (82.7 %) underwent surgery, 33 (63.5 %) had R0 resection, and there was no treatment-related death. The pathological response was 34.6 % (95 % CI 22.0–49.1) for all registered patients; the null hypothesis of tumor response ≤10 % was rejected (p < 0.0001). The 3-year overall survival was 41.5 % (95 % CI 27.4–55.0).Conclusions
The neoadjuvant chemotherapy with TC was safe and effective for patients with locally advanced gastric cancer, and further study is needed to confirm the effectiveness of this regimen. 相似文献7.

BACKGROUND:
Prostate cancer trials investigating neoadjuvant hormonal therapy, followed by surgery, have demonstrated that elimination of all tumor cells from the primary site is rare. The authors report a phase 2 trial assessing the efficacy and toxicity of docetaxel and gefitinib in patients with high‐risk localized prostate cancer as neoadjuvant therapy before radical prostatectomy (RP).METHODS:
Thirty‐one patients with high‐risk prostate cancer were treated with docetaxel and gefitinib for 2 months before RP. All patients met the criteria of clinical stage T2b‐3 or serum prostate‐specific antigen (PSA) level >20 ng/mL, or Gleason score of 8 to 10. The primary endpoint was pathologic complete response. Secondary objectives included clinical response. When available, endorectal coil magnetic resonance imaging (eMRI) was performed as part of clinical response evaluation. Immunohistochemical staining of epidermal growth factor receptor and HER‐2/neu was performed on prechemotherapy and postchemotherapy prostate tissue.RESULTS:
The median age of the patients was 60 years, the median pretreatment PSA level was 7.43 ng/mL, and the median Gleason score was 8. Clinical staging prior to treatment consisted of: T1 in 4 patients, T2 in 17 patients, and T3 in 10 patients. One patient with enlarged pelvic adenopathy and T4 disease did not undergo RP. Thirty patients received all scheduled therapies including RP. Grade 3 toxicities included asymptomatic liver function test elevation in 4 (13%) patients, diarrhea in 1 (3%) patient, and fatigue in 1 (3%) patient. One patient experienced grade 4 toxicity with elevated alanine aminotransferase. RP specimen pathology demonstrated residual carcinoma in all cases. Twenty‐nine (94%) patients achieved a clinical partial response, including 35% of patients who demonstrated radiographic improvement on eMRI.CONCLUSIONS:
No pathologic complete response was noted in 31 patients treated with docetaxel and gefitinib. This combination was well tolerated, and did not result in increased surgical morbidity. Cancer 2009. © 2009 American Cancer Society. 相似文献8.

Purpose We designed this phase I/II study of docetaxel–oxaliplatin combination chemotherapy to determine the dose-limiting toxicity
(DLT), maximum tolerated dose and efficacy as a first-line treatment in patients with advanced gastric cancer.
Methods Patients with histologically proven, chemo-naive gastric adenocarcinoma were eligible. For the phase I part, three dose levels
of oxaliplatin and docetaxel every 3 weeks were tested in a cohort of three patients for each level (respectively, 100 and
60 mg/m2, 100 and 75 mg/m2, 130 and 75 mg/m2). Patients were treated up to a maximum of nine cycles of oxaliplatin and docetaxel unless there was documented disease progression,
an unacceptable adverse event, or withdrawal of consent.
Results No DLT was observed at any of the three levels tested in the phase I portion. Therefore, oxaliplatin 130 mg/m2 and docetaxel 75 mg/m2 were recommended for the phase II study. All 47 patients were evaluable for toxicity and treatment response. The overall
response rate was 55.3% (95% CI, 40.6–70.1%) and median duration of response was 4.2 months (range 0.9–9.5 months). After
a median follow-up duration of 13.3 months, median overall survival was 12.7 months (95% CI: 10.4–14.9). The median time to
progression was 5.0 months (95% CI, 3.4–6.5 months). The main toxicities (grade 3 or 4) were febrile neutropenia (14.9%),
neutropenia (23.4%), diarrhea (10.6%) and neurotoxicity (8.5%).
Conclusion The combination of docetaxel and oxaliplatin was feasible with favorable toxicity profile and showed a promising anti-tumor
activity in unresectable, metastatic gastric cancer patients. 相似文献

Purpose
To evaluate the feasibility and efficacy of neoadjuvant chemotherapy involving docetaxel and cisplatin followed by intensity-modulated radiotherapy (IMRT) with concurrent cisplatin in patients with newly diagnosed stage III to IVB nasopharyngeal carcinoma (NPC).Methods
Docetaxel (75 mg/m2 on day 1) and cisplatin (75 mg/m2 on day 1) were administered on a 3-week cycle for 2 courses, followed by radical IMRT (72 Gy/33F/6.5–7 W) with concurrent cisplatin (75 mg/m2, on day 1) every 3 weeks for 2 cycles.Results
From June 2008 to October 2010, forty-six patients were recruited in this trial. Forty-five patients completed neoadjuvant setting, and all patients completed planned concurrent chemoradiotherapy (CCRT). The complete and partial response rates were 28.3 and 56.5 % after neoadjuvant chemotherapy, and 91.3, 8.7 % after CCRT, respectively. After median follow-up of 26 months (range 12–39 months), one patient experienced local recurrence and 4 patients developed distant metastasis. The 3-year overall survival and progression-free survival rate were 94.1 and 72.7 %, respectively. Neutropenia (37.0 %) and vomiting (28.3 %) were the most common Grade 3–4 adverse effects during neoadjuvant course, while mucositis (30.4 %), xerostomia (30.4 %) and radiodermatitis (21.7 %) were the most common Grades 3 acute toxicities during CCRT. Xerostomia (73.9 %), dysphagia (56.5 %), hear loss (30.4 %) and skin reaction (21.7 %) were the common Grade 1–2 late effects. There were no Grades 3–4 late toxicities.Conclusions
The protocol of neoadjuvant docetaxel and cisplatin followed by IMRT with concurrent cisplatin was well tolerated, with outstanding compliance and efficacy in locally advanced NPC, which deserved further follow-up. 相似文献13.

Background
The aim of this study was to evaluate the efficacy and feasibility of preoperative chemotherapy with S-1 plus cisplatin in patients with initially unresectable locally advanced gastric cancer.Methods
We enrolled patients with initially unresectable locally advanced gastric cancer because of severe lymph node metastases or invasion of adjacent structures. Preoperative chemotherapy consisted of S-1 at 80 mg/m2 divided in two daily doses for 21 days and cisplatin at 60 mg/m2 intravenously on day 8, repeated every 35 days. If a tumor decreased in size, patients received 1 or 2 more courses. Surgery involved radical resection with D2 lymphadenectomy.Results
Between December 2000 and December 2007, 27 patients were enrolled on the study. No CR was obtained, but PR was seen in 17 cases, and the response rate was 63.0%. Thirteen patients (48.1%) had R0 resections. There were no treatment related deaths. The median overall survival time (MST) and the 3-year overall survival (OS) of all patients were 31.4 months and 31.0%, respectively. Among the 13 patients who underwent curative resection, the median disease-free survival (DFS) and the 3-year DFS were 17.4 months and 23.1%, respectively. The MST and the 3-year OS were 50.1 months and 53.8%, respectively. The most common site of initial recurrence after the R0 resection was the para-aortic lymph nodes.Conclusions
Preoperative S-1 plus cisplatin can be safely delivered to patients undergoing radical gastrectomy. This regimen is promising as neoadjuvant chemotherapy for resectable gastric cancer. For initially unresectable locally advanced gastric cancer, new trials using more effective regimens along with extended lymph node dissection are necessary. 相似文献16.

BackgroundEpidermal growth factor receptor (EGFR) is overexpressed in pancreatic cancer. EGFR expression plays a potentially important role in modulation of tumor sensitivity to either chemotherapy or radiotherapy. Erlotinib is a receptor tyrosine kinase inhibitor with specificity for EGFR/HER1. A phase II trial was conducted to explore the efficacy of a regimen utilizing erlotinib and proton therapy.MethodsPatients with unresectable or borderline resectable non-metastatic adenocarcinoma of the pancreas were included. Patients received 8-week systemic treatment with gemcitabine 1,000 mg/m2 and erlotinib 100 mg (GE). If there was no evidence of metastatic disease after GE, then patients preceded with proton therapy to 50.4 Gy in 28 fractions with concurrent capecitabine 825 mg/m2 (CPT). This was followed with oxaliplatin 130 mg/m2 and capecitabine 1,000 mg/m2 (CapOx) for 4 cycles. The primary study objective was 1-year overall survival (OS). The benchmark was 43% 1-year survival as demonstrated in RTOG/NRG 98-12. The Kaplan-Meier method was used to estimate the one-year OS and the median OS and progression-free survival (PFS).ResultsThe study enrolled 9 patients ages 47–81 years old (median 62) between January 2013 and March 2016, when the trial was closed due to low patient accrual. The 1-year OS rate was 55.6% (95% CI: 31% to 99%). The median OS was 14.1 months (95% CI: 11.4–NE) and the median PFS was 10.8 months (95% CI: 7.44–NE). A majority of patients completed CPT and GE, but only 33.3% completed the four cycles of CapOx. A third of patients experienced grade 3 toxicities, which were all hepatic along with one patient who also had grade 3 diarrhea. There were no grade 4 or 5 toxicities. Four patients were enrolled with borderline resectable disease, three of which were eligible for pancreaticoduodenectomy after GE and CPT treatment. One of two patients who underwent resection had a negative margin.ConclusionsThis regimen for locally advanced pancreatic cancer (LAPC) exceeded the pre-specified benchmark and was safe and well tolerated. Additional investigations utilizing more current systemic treatment regimens with proton therapy are warranted.Trial RegistrationClinicalTrials.gov identifier (NCTNCT01683422). 相似文献

PURPOSE: Preoperative chemotherapy is the conventional primary treatment in locally advanced breast cancer (LABC). We investigated the safety and efficacy of primary twice-weekly paclitaxel and concurrent radiation (RT) before modified radical mastectomy followed by adjuvant doxorubicin-based chemotherapy. PATIENTS AND METHODS: Stage IIB (T3N0) to III LABC patients were eligible. Primary chemoradiation consisted of paclitaxel, 30 mg/m(2) delivered intravenously for 1 hour twice weekly for a total of 8 to 10 weeks, and concurrent RT (45 Gy at 1.8 Gy/fraction). Modified radical mastectomy was performed at least 2 weeks after completion of chemoradiation or on recovery of skin toxicity. Postoperatively, patients who responded to paclitaxel and RT received four cycles of doxorubicin/paclitaxel, whereas patients who did not respond received doxorubicin/cytoxan. RESULTS: Forty-four patients were accrued. Toxicity from paclitaxel/RT included grade 3 skin desquamation (7%), hypersensitivity (2%), and stomatitis (2%). Postsurgery complications occurred in six patients (14%). The only grade 4 toxicity of postmastectomy chemotherapy was hematologic (10%). Grade 3 toxicities were leukopenia (24%), infection (22%), peripheral neuropathy (17%), arthralgia and pain (17%), stomatitis (12%), fatigue (10%), esophagitis (5%), and nausea (2%). Overall clinical response rate to preoperative paclitaxel and RT was 91%. Thirty-four percent of patients achieved a pathologic response in the mastectomy specimen: 16% pathologic complete responses (clearance of invasive cancer in the breast and axillary contents) and 18% pathologic partial responses (< 10 residual microscopic foci of invasive breast cancer). CONCLUSION: Twice-weekly paclitaxel with concurrent RT is a feasible and effective primary treatment for LABC. Future studies should compare primary chemoradiation to chemotherapy in LABC. 相似文献

In Western countries, the standard treatment for locally advanced rectal cancer is preoperative chemoradiotherapy followed by total mesorectal excision. On the other hand, in Japan, treatment results without radiotherapy are by no means inferior; therefore, extrapolation of results of preoperative treatment in Western countries to Japan is controversial. We consider that survival may be improved by preoperative treatment with new anticancer agents as they are expected not only to decrease the local recurrence rate but also to prevent distant metastases. We are conducting a multicentre Phase II study to evaluate the safety and efficacy of neoadjuvant chemotherapy using XELOX plus bevacizumab without radiotherapy in patients with locally advanced rectal cancer. The primary endpoint of the study is treatment compliance. Secondary endpoints are overall survival, disease-free survival, local recurrence-free survival, objective response rate, R0 resection rate and adverse events. Thirty patients are required for this study. 相似文献

Background
Neoadjuvant chemoradiotherapy (CRT) reduces local tumor recurrence in locally advanced rectal cancer (LARC). This phase II study assessed neoadjuvant cetuximab with capecitabine-based CRT in LARC.Methods
Patients with stage II/III LARC received capecitabine 1250 mg/m2 twice daily for 2 weeks followed by intravenous cetuximab 400 mg/m2 at week 3, then weekly intravenous 250 mg/m2 cetuximab plus CRT including capecitabine 825 mg/m2 twice daily (including weekends during radiotherapy) with radiotherapy of 45 Gy (25 × 1.8 Gy), 5 days a week for 5 weeks. Total mesorectal excision was scheduled 4–6 weeks following completion of CRT. The primary endpoint was pathological complete response (pCR).Results
Thirty-seven patients were eligible for safety and efficacy. TMN staging at baseline was: T4N2, 11%; T3N2, 40%; T2N2, 3%; T3N1, 35%; T2N1, 3% and T3N0 8%. The most common adverse events included, grade 1/2 acneiform skin rash (86%), and grade 3 radiodermatitis, (16%), diarrhea (11%) and hypersensitivity (5%). pCR was achieved in 3 patients (8%). Overall-, T- and N-downstaging rates were 73%, 57% and 81% respectively. Total sphincter preservation rate was 76%, and 53% in 17 patients whose tumors were located within 5 cm from the anal verge. Non-fatal perioperative complications occurred in 13 patients (35%) with delayed wound healing occurring in 6 patients (16%). One death was recorded due to sepsis following colonic necrosis.Conclusion
Neoadjuvant cetuximab with capecitabine-based CRT is tolerable in patients with resectable LARC. Whilst the pCR rate was similar to recent reports, a high pathological downstaging rate was achieved. 相似文献20.
