Although it is possible to cure many patients with locally advanced cervical cancer using radiation therapy alone, loco-regional relapse continues to be a component of most recurrences. To improve control rates, clinicians have investigated ways of combining chemotherapy and radiation for more than 30 years. Despite encouraging results from phase II trials of neoadjuvant chemotherapy, randomized trials failed to improve on the results with radiation therapy alone. For a number of reasons, early trials of concurrent chemoradiation were inconclusive. However, recent reports of five large prospective randomized trials demonstrated dramatic improvements in survival and local control rates when cisplatin-containing chemotherapy was given during radiation therapy. These results also suggest a number of avenues for future research. 相似文献

Late-onset (LO) toxicities are a serious concern in many phase I trials. Since most dose-limiting toxicities occur soon after therapy begins, most dose-finding methods use a binary indicator of toxicity occurring within a short initial time period. If an agent causes LO toxicities, however, an undesirably large number of patients may be treated at toxic doses before any toxicities are observed. A method addressing this problem is the time-to-event continual reassessment method (TITE-CRM, Cheung and Chappell, 2000). We propose a Bayesian dose-finding method similar to the TITE-CRM in which doses are chosen using time-to-toxicity data. The new aspect of our method is a set of rules, based on predictive probabilities, that temporarily suspend accrual if the risk of toxicity at prospective doses for future patients is unacceptably high. If additional follow-up data reduce the predicted risk of toxicity to an acceptable level, then accrual is restarted, and this process may be repeated several times during the trial. A simulation study shows that the proposed method provides a greater degree of safety than the TITE-CRM, while still reliably choosing the preferred dose. This advantage increases with accrual rate, but the price of this additional safety is that the trial takes longer to complete on average. 相似文献

The authors present a case report of a patient with breast cancer diagnosed in 2005, treated with conservative surgery, adjuvant chemotherapy and radiotherapy, followed by hormonal therapy until 2010, who relapsed under the form of inflammatory breast cancer in 2011. After tumor progression detected during primary systemic therapy, a concurrent radiation and radiosensitizing chemotherapy were proposed. There was a significant clinical response to this treatment, enabling curative chance with total mastectomy. The histological examination of the breast and regional lymph nodes revealed a complete response, since there was no evidence of residual tumor.There are few reports concerning concurrent radiotherapy and chemotherapy in locally advanced breast cancer, but it could be a suitable “loco regional rescue therapy” to further reduce tumor progression and allow curative surgery. Study of this treatment strategy in randomized clinical trials is warranted. 相似文献

Since 1983, a series of experimental and clinical studies have been carried out on the possibility of enhancing the chemotherapy effectiveness in breast cancer by expanding the fraction of cycling cells. Theoretically estrogens should recruit breast cancer cells and this fact should result in a higher killing efficiency of antiproliferative drugs. Actually it has been clearly shown, by means of the thymidine labeling index and primer-dependent -DNA polymerase assay, that low doses of diethylstilbesterol are able to increase the tumor proliferative activity of human breast cancer in vivo (estrogenic recruitment).
Three randomized trials have been carried out (one in locally advanced and two in metastatic breast cancer) comparing conventional polichemotherapy vs chemotherapy with estrogenic recruitment. Only limited advantages have been observed in these trials.
Searching for new modalities of kinetic manipulation of tumors, recombinant human growth hormone has been employed in a pilot study: the preliminary results indicate that it largely enhances tumor proliferative activity, suggesting the possibility of employing a growth factor system to increase chemosensitivity. 相似文献

High-dose chemotherapy (HDCT) plus autologous hematopoietic stem-cell transplantation (HSCT) has been explored in several solid tumors in the attempt to prevent and/or overcome tumor-cell chemo-resistance, based on in vitro evidence of a "dose-response" effect. Preliminary encouraging results from non-randomized trials, led to an increased use of this strategy in the 1990s. Since the end of the nineties, the fraudulent nature of initial reports in breast cancer, the failure of positive prospective randomized trials, HDCT-related toxicities, determined a dramatic decline of interest in this approach. Loss of accrual in ongoing randomized studies was the first consequence, causing the current unavailability of optimal information. From the review of available published data, the use of HDCT with autologous HSCT may improve tumor response rates and/or possibly progression-free survival, especially in some selected patient subgroups. However, this strategy did not demonstrate in almost all cases to produce significantly higher cure rates than standard-dose chemotherapy. Well-designed randomized studies and future strategies integrating HDCT with concomitant and/or subsequent anti-tumor therapies targeted against the residual disease might be suggested in clinically and biologically selected patients. 相似文献

We report the first treatment of metastatic breast cancer by systemic radioimmunotherapy. The serial therapy doses were chosen based on quantitative imaging data in a treatment planning approach. A terminally ill patient with aggressive, locally advanced breast cancer who had failed radiation treatment and chemotherapy was injected intravenously with radiolabeled I-131 chimeric L6, a human-mouse chimeric lgG1 monoclonal antibody to adenocarcinoma. Initially, an imaging 10 mCi dose of I-131 chimeric L6 (dose 1) deposited 8.8% of the injected dose in her chest wall tumor at 48 hours. Ten days later the patient was given a 150 mCi I-131 chimeric L6 dose (dose 2) followed three weeks later by a 100 mCi dose (dose 3). Tumor uptake and retention were comparable for doses 1 and 2, and decreased for dose 3. Following dose 3 the patient developed a manageable thrombocytopenia and transient Grade IV granulocytopenia. The tumor was observed to decrease in size with peak tumor regression occurring two weeks after dose 3. This partial response (PR) was achieved by radioimmunotherapy at a time when conventional therapy had been unable to impact the growth of the patient's massive and aggressive tumor. 相似文献

AimTo assess the oncological outcomes of patients with early breast cancer treated with breast-conserving surgery and adjuvant hypofractionated radiation therapy.Methods and MaterialThis retrospective analysis included all patients ≥50 year of age with T1-2 N0 M0 breast cancer treated at our Radiation Oncology Unit between 2008 and 2011. Whole-breast radiation therapy was delivered to a dose of 42.5 Gy in 16 fractions, without boost. The primary outcome was local control.Results212 patients were identified. With a median follow up of 60 months, we found 3% local recurrence and 5.3% regional and/or distant recurrences. At the moment of data analysis, 17 patients had died. Out of 5 local recurrences, 2 had previously had a distant recurrence, both of them died. The other three were still alive at the last follow up. These results are comparable to those observed in Phase III trials that use this fractionation scheme.ConclusionsThe results obtained with this retrospective analysis are comparable to those obtained in large randomized trials. This data also supports the use of hypofractionated radiation therapy in Latin America. Hypofractionated radiation therapy for early breast cancer patients should be the standard adjuvant treatment. 相似文献

The menopause,hormone replacement therapy and breast cancer 总被引:2,自引:0,他引:2

Concern exists that the reduction in breast cancer risk associated with the onset of the menopause will be negated with exposure to hormone replacement therapy (HRT). Evidence from large-scale randomised HRT trials support observational data that have shown a modest increase in breast cancer risk with long-term use (i.e. >15 years) of combined therapy, although this falls following HRT cessation suggesting a growth-promoting effect. Randomised evidence demonstrates that the efficacy of anti-estrogens, aromatase inhibitors and raloxifene in the treatment and chemoprevention of breast cancer are restricted to women with oestrogen receptor positive (ER +ve) disease; however, HRT has not been associated conclusively with a predominance of hormone sensitive breast cancer. Despite stimulating the breast cancer cell growth, HRT has not been shown to increase breast cancer recurrence or mortality when prescribed to breast cancer survivors experiencing oestrogen deficiency symptoms and randomised trials have been recommended and commenced. In conjunction with controlled breast cancer trials demonstrating a therapeutic benefit of high dose estrogens and interest in the use of additive oestrogen therapy in patients developing resistance to oestrogen deprivation, the dogma that HRT is an absolute contra-indication following diagnosis is challenged. 相似文献

The third-generation aromatase inhibitors are an important class of drugs for use in adjuvant therapy for postmenopausal women with resected estrogen receptor positive breast cancer. Multiple large prospective randomized trials have established their value in this setting and provided guidance for their use in clinical management. This review will outline the trials that have provided evidence on the value of the aromatase inhibitors in the adjuvant setting as well as the ongoing trials that will expand our knowledge of how to use them most effectively. 相似文献

Increasingly, bone marrow transplant (BMT) is the treatment of choice for certain hematologic diseases. BMT is, however, a risky procedure with many potentially serious complications. Some complications are the result of the conditioning regimen, a stage of transplantation that includes large doses of chemotherapy and/or radiation therapy. Conditioning-induced neutropenia and thrombocytopenia often result in infection, bleeding, and mucositis. Veno-occlusive disease (VOD), a chemotherapy-induced hepatotoxicity, can cause a mild to severe form of liver disease. Other complications are directly attributable to the engrafted new marrow. Graft-versus-host disease, a rejection process initiated by immunocompetent donor T lymphocytes, is a complication frequently observed in allogeneic BMT. Approximately 14-28 days after the day of transplant, signs of engraftment begin to appear. When specific discharge criteria are met, the BMT patient is discharged from the hospital. Specific follow-up medical care is ongoing for about one year after BMT. 相似文献

Successful treatment of cancer patients with a combination of monoclonal antibodies (mAb) and chemotherapeutic drugs has spawned
various other forms of additional combination therapies, including vaccines or adoptive lymphocyte transfer combined with
chemotherapeutics. These therapies were effective against established tumors in animal models and showed promising results
in initial clinical trials in cancer patients, awaiting testing in larger randomized controlled studies. Although combination
between immunotherapy and chemotherapy has long been viewed as incompatible as chemotherapy, especially in high doses meant
to increase anti-tumor efficacy, has induced immunosuppression, various mechanisms may explain the reported synergistic effects
of the two types of therapies. Thus direct effects of chemotherapy on tumor or host environment, such as induction of tumor
cell death, elimination of regulatory T cells, and/or enhancement of tumor cell sensitivity to lysis by CTL may account for
enhancement of immunotherapy by chemotherapy. Furthermore, induction of lymphopenia by chemotherapy has increased the efficacy
of adoptive lymphocyte transfer in cancer patients. On the other hand, immunotherapy may directly modulate the tumor’s sensitivity
to chemotherapy. Thus, anti-tumor mAb can increase the sensitivity of tumor cells to chemotherapeutic drugs and patients treated
first with immunotherapy followed by chemotherapy showed higher clinical response rates than patients that had received chemotherapy
alone. In conclusion, combination of active specific immunotherapy or adoptive mAb or lymphocyte immunotherapy with chemotherapy
has great potential for the treatment of cancer patients which needs to be confirmed in larger controlled and randomized Phase
III trials. 相似文献

The pharmacologic inhibition of aromatase activity has been the focus of clinical trials in patients with advanced stage breast cancer. Recent developments with imidazole compounds that inhibit aromatase activity suggest their clinical use as potent inhibitors of estrogen biosynthesis in postmenopausal breast cancer patients. In this Phase I, open-label, dose-range finding study, we examined the inhibitory potency of CGS 20267 on blood and urine levels of estradiol, estrone and estrone sulfate in 8 patients with metastatic breast cancer. Studies included evaluation of adrenal and thyroid function to look for evidence of general hydroxylase inhibition at dose levels effective for aromatase blockade. Patients were administered CGS 20267 at doses of 0.1 and 0.25 mg, once a day in ascending doses over a 12-week period. Preliminary data reveal that CGS 20267 elicits a striking suppression in plasma estradiol, estrone and estrone sulphate which was observed in some patients as quickly as within 24 h of the first dose. Estrogen suppression of over 90% was achieved within 2 weeks of therapy. No alterations in either baseline or ACTH (cortrosyn) stimulated cortisol and aldosterone levels were observed through the 12 weeks of therapy. In addition, 24 h urine sodium and potassium values were not appreciably altered during therapy. We conclude that CGS 20267 is a potent, specific inhibitor of estrogen biosynthesis in postmenopausal patients with metastatic breast cancer and effectively reduces blood and urine estrogens to undetectable levels. 相似文献

Estrogens and women's health: interrelation of coronary heart disease, breast cancer and osteoporosis 总被引:1,自引:0,他引:1

The determinants of blood levels of estrogen, estrogen metabolites, and relation to receptors and post-transitional effects are the likely primary cause of breast cancer. Very high risk women for breast cancer can now be identified by measuring bone mineral density and hormone levels. These high risk women have rates of breast cancer similar to risk of myocardial infarction. They are candidates for SERM therapies to reduce risk of breast cancer. The completion of the Women's Health Initiative and other such trials will likely provide a definite association of risk and benefit of both estrogen alone and estrogen-progesterone therapy, coronary heart disease, osteoporotic fracture, and breast cancer. The potential intervention of hormone replacement therapy, obesity, or weight gain and increased atherogenic lipoproteinemia may be of concern and confound the results of clinical trials. Estrogens, clearly, are important in the risk of bone loss and osteoporotic fracture. Obesity is the primary determinant of postmenopausal estrogen levels and reduced risk of fracture. Weight reduction may increase rates of bone loss and fracture. Clinical trials that evaluate weight loss should monitor effects on bone. The beneficial addition of increased physical activity, higher dose of calcium or vitamin D, or use of bone reabsorption drugs in coordination with weight loss should be evaluated. Any therapy that raises blood estrogen or metabolite activity and decreases bone loss may increase risk of breast cancer. Future clinical trials must evaluate multiple endpoints such as CHD, osteoporosis, and breast cancer within the study. The use of surrogate markers such as bone mineral density, coronary calcium, carotid intimal medial thickness and plaque, endothelial function, breast density, hormone levels and metabolites could enhance the evaluation of risk factors, genetic-environmental intervention, and new therapies. 相似文献

There have been significant improvements in the radiotherapeutic management of patients with high risk prostate cancer. Randomized trials have clearly demonstrated improved outcomes with the combination of radiotherapy in conjunction with androgen deprivation. While these trials have utilized low doses of radiotherapy in the range of 70 Gy, recent studies have suggested that significant benefits of combined androgen deprivation therapy with dose escalated radiotherapy are also observed. The use of high radiation dose levels in the setting of high risk prostate cancer is important, and strategies which combine external beam radiotherapy with a brachytherapy boost may provide an opportunity for even greater intensification of the radiation dose to the prostate target. Systemic therapies, second generation anti-androgen therapy and novel targeted agents integrated with radiotherapy will open up new vistas and challenges for further improved outcomes in patients with high-risk disease. 相似文献

In order to evaluate the role of inherited BRCA2 mutations in American families--particularly the appearance in America of European founder mutations--the BRCA2 coding sequence, 5' UTR, and 3' UTR were screened in 22 Caucasian American kindreds with four or more cases of breast or ovarian cancer. Six mutations were found that cause a premature-termination codon; four of them have been reported elsewhere, and two are novel. In the four families with previously seen mutations, the distinct lineages at high risk of cancer were of Dutch, German, Irish, and Ashkenazi Jewish ancestry; mutations in Europe reflect these ancestries. The families with novel mutations were Puerto Rican Hispanic (exon 9 deletion 995delCAAAT) and Ashkenazi Jewish (exon 11 deletion 6425delTT). Among female BRCA2-mutation carriers, risks of breast cancer were 32% by age 50 years, 67% by age 70 years, and 80% by age 90 years, yielding a lifetime risk similar to that for BRCA1 but an older distribution of ages at onset. BRCA2 families also included multiple cases of cancers of the male breast (six cases), ovary (three cases), fallopian tube (two cases), pancreas (three cases), bladder (two cases), and prostate (two cases). Among 17 Ashkenazi Jewish families with four or more breast or ovarian cancers, 9 families (including 3 with ovarian cancer and 1 with male breast cancer) carried none of the three ancient mutations in BRCA1 or BRCA2. To date, both BRCA2 and BRCA1 have been screened by SSCA, supplemented by the protein-truncation test, in 48 families with four or more breast or ovarian cancers. Mutations have been detected in BRCA1 in 33 families, in BRCA2 in 6 families, and in neither gene in 9 families, suggesting both the probable cryptic nature of some mutations and the likelihood of at least one other BRCA gene. 相似文献

The author summarizes the progress of adjuvant chemotherapy of breast cancer from the classical Bonadonna-type CMF over the anthracyclines to the taxanes. The CMF regimen represented the prototype of combination chemotherapy which significantly improved early and long term results. After 20 years the patients given adjuvant combination chemotherapy with CMF had significantly better rates of relapse-free survival (p<0.001) and overall survival (p=0.03) compared with no chemotherapy. 6 cycles of CMF was the gold standard of adjuvant chemotherapy in breast cancer for decades. The Milan research group decided in the early 1980s to challange this popular CMF combination by introducing doxorubicin within the adjuvant program. Compared with standard CMF, anthracyclin-containing regimens reduced the annual risk of recurrence by 12% and the annual risk of death by 11%, equating to a 3.2% absolute reduction in recurrence and a 2.7% absolute reduction in mortality at 5 years. This small but real difference seen with regimens containing three or more agents (e.g. CEF and CAF, FAC, FEC, etc.), whereas 4 cycles of 2-drug regimens (e.g. AC or EC) appears to be equivalent to 6 cycles of CMF. Among the novel chemotherapeutic drugs introduced in the 1990s the taxanes have emerged as the most powerful compounds in breast cancer. Several large, adjuvant clinical trials are currently ongoing or have recently completed accrual. The available results from innumerable clinical studies are still inconclusive and do not support the routine use of taxanes in the adjuvant setting - with the exception of the BCIRG 001 docetaxel trial, in which significant improvement was documented in disease free survival with 6 x TAC compared with 6 x FAC (82% vs 74%). Studies on the effect of the new trastuzumab (an antibody against the extracellular domain of the HER2) in adjuvant setting was initiated in early 2000. The Herceptin adjuvant trial programme is extensive, involving more than 12,000 patients worldwide. This trials will potentially offer many women with HER2-positive disease the chance of improved survival. 相似文献

Menopausal hormone therapy with estrogen plus progestin or estrogen alone (for women with prior hysterectomy) is still used by millions of women for climacteric symptom management throughout the world. Until 2002, hormone therapy influence on cancer risk and other chronic diseases was determined through observational study reports. Since then, results from the Women’s Health Initiative randomized, placebo-controlled hormone therapy trials have substantially changed concepts regarding estrogen plus progestin and estrogen alone influence on the most common cancers in postmenopausal women. In these trials, estrogen plus progestin significantly increased breast cancer incidence and deaths from breast cancer, significantly increased deaths from lung cancer, significantly decreased endometrial cancer, and did not have a clinically significant influence on colorectal cancer. In contrast, estrogen alone use in women with prior hysterectomy significantly reduced breast cancer incidence and deaths from breast cancer without significant influence on colorectal cancer or lung cancer. These complex results are discussed in the context of known potential mediating mechanisms of action involved in interaction with steroid hormone receptors. 相似文献

Background
Capecitabine has proven effective as a chemotherapy for metastatic breast cancer. Though several Phase II/III studies of capecitabine as neoadjuvant chemotherapy have been conducted, the results still remain inconsistent. Therefore, we performed a meta-analysis to obtain more precise understanding of the role of capecitabine in neoadjuvant chemotherapy for breast cancer patients.Methods
The electronic database PubMed and online abstracts from ASCO and SABCS were searched to identify randomized clinical trials comparing neoadjuvant chemotherapy with or without capecitabine in early/operable breast cancer patients without distant metastasis. Risk ratios were used to estimate the association between capecitabine in neoadjuvant chemotherapy and various efficacy outcomes. Fixed- or random-effect models were adopted to pool data in RevMan 5.1.Results
Five studies were included in the meta-analysis. Neoadjuvant use of capecitabine with anthracycline and/or taxane based therapy was not associated with significant improvement in clinical outcomes including: pathologic complete response in breast (pCR; RR = 1.10, 95% CI 0.87–1.40, p = 0.43), pCR in breast tumor and nodes (tnpCR RR = 0.99, 95% CI 0.83–1.18, p = 0.90), overall response rate (ORR; RR = 1.00, 95% CI 0.94–1.07, p = 0.93), or breast-conserving surgery (BCS; RR = 0.98, 95% CI 0.93–1.04, p = 0.49).Conclusions
Neoadjuvant treatment of breast cancer involving capecitabine did not significantly improve pCR, tnpCR, BCS or ORR. Thus adding capecitabine to neoadjuvant chemotherapy regimes is unlikely to improve outcomes in breast cancer patients without distant metastasis. Further research is required to establish the condition that capecitabine may be useful in breast cancer neoadjuvant chemotherapy. 相似文献19.

The pathophysiologies of osteoporosis, cardiovascular disease, and breast cancer are briefly reviewed within the context of the relevance and safety of long-term estrogen therapy (ET). Extrapolation of data from the known underlying biology of these diseases and the results of randomized controlled clinical trials suggest that selective ET is appropriate and safe for the majority of postmenopausal women. A key element to this clinical practice is individualization of ET, which includes timing of the initiation of therapy, selection of the route and possibly the type of estrogen prescribed, adjustment of the dose of estrogen over time to compensate for local tissue estrogen synthesis, and annual monitoring and reassessment of the indication for continuing therapy. Established disease requires disease-specific therapy but does not exclude ET cotherapy provided there is an indication for its use. Estrogen-dependent cancer is an absolute contraindication to systemic ET. 相似文献

Reporting of gender-related information in clinical trials of drug therapy for myocardial infarction
BACKGROUND: Concern has been expressed that women are not adequately represented in clinical trials evaluating treatments for medical conditions they commonly experience. This study was designed to assess the reporting of data on women in recently published trials of drug therapy for myocardial infarction, including those funded by an agency with a gender-related policy. METHODS: All randomized controlled trials and meta-analyses of drug therapies for myocardial infarction published in The New England Journal of Medicine, The Lancet, The Journal of the American Medical Association, the Annals of Internal Medicine and the British Medical Journal from January 1992 to December 1996 were evaluated. On preliminary review 102 articles met the inclusion criteria; these were reviewed in detail, and 59 were excluded. Two reviewers independently extracted gender-related information from the 43 articles; discrepancies were resolved by consensus. RESULTS: Women presented up to 48% of the trial participants (mean 24.1%). In the trials funded by an agency with a gender-related policy, only 16.8% of participants, on average, were women. Of the 43 articles in the sample, only 14 (32%) provided gender-related results. Funding from an agency with gender-related policy did not affect the reporting of gender-related information. Subgroup analyses were provided for 14 (32%) of the 43 trials, including 2 (29%) of 7 trials funded by an agency with a gender-related policy. Of the 12 trials that included interaction analyses (excluding the 2 trials in which secondary analyses were conducted specifically to identify differences between women and men), 7 (58%) conducted an interaction analysis to determine if women responded differently than men; for one of these the interaction analysis was for a secondary outcome measure (drug safety). Only 5 (12%) of the 43 articles mentioned the differences between men and women in the Discussion section; 2 of these were studies that used secondary analyses to examine sex differences. Of the 5, only 1 was funded by an agency with a gender-related policy. INTERPRETATION: Women were poorly represented in the randomized controlled trials in this sample, regardless of whether the trials were funded by an agency with a gender-related policy. Structured reporting of gender-related information for clinical trials may improve the quality of information available about women and therefore facilitate the application of research findings to the care of women. 相似文献
