    2009-01-01

    Methylenetetrahydrofolate reductase is a pivotal enzyme in folate metabolism and 5-fluorouracil (5-FU) cytotoxicity. Two common single-nucleotide polymorphisms (SNPs), MTHFR 677C>T (rs1801133) and 1298A>C (rs1801131), reduce enzyme activity. Initially, these SNPs were claimed to predict clinical....../leucovorin chemotherapy after intended curative resection between 1997 and 2003. Clinical data, including relapse rates, overall survival, and tumor stage, were collected. DNA was extracted from formalin-fixed tumor tissue and analyzed for the MTHFR 677C>T and 1298A>C SNPs with real-time PCR. Results: The MTHFR 677C...... colorectal cancer after complete resection; however, the 677C>T polymorphism may be associated with lower toxicity in 5-FU treatment. Implementation of SNP analysis for these polymorphisms for individualized treatment is premature....

    p21-Activated kinase 6 (PAK6) has been implicated in radiotherapy and docetaxel resistance. We have further evaluated PAK6 as a predictor of 5-fluorouracil (5-FU) treatment response in colon cancer. Here we report that in colon cancer PAK6 promotes tumor progression and chemoresistance both in vitro and in vivo. In the clinical analysis, PAK6 was overexpressed in 104 of 147 (70.75%) stage II and III patients who received 5-FU based chemotherapy after surgery. Multivariate Cox regression analysis indicated that PAK6 was an independent prognostic factor for overall survival (P < 0.001) and disease-free survival (P < 0.001). Colon cancer cell lines showed increased PAK6 expression upon 5-FU treatment. In PAK6-knockdown cells treated with 5-FU, cell viability and phosphorylation of BAD decreased, and the number of apoptotic cells, levels of cleaved caspase 3 and PARP increased compared to control cells. The opposite was observed in PAK6 overexpressing cells. Short hairpin RNA knockdown of PAK6 blocked cells in G2-M phase. Furthermore, Animal experiments results in vivo are consistent with outcomes in vitro. This study demonstrates that PAK6 is an independent prognostic factor for adjuvant 5-FU-based chemotherapy in patients with stage II and stage III colon cancer. PMID:25426562

  3. Low levels of Caspase-3 predict favourable response to 5FU-based chemotherapy in advanced colorectal cancer: Caspase-3 inhibition as a therapeutic approach.

    Colorectal cancer (CRC) is one of the most common cancers in the Western world. 5-Fluorouracil (5FU)-based chemotherapy (CT) remains the mainstay treatment of CRC in the advanced setting, and activates executioner caspases in target cells. Executioner caspases are key proteins involved in cell disassembly during apoptosis. Activation of executioner caspases also has a role in tissue regeneration and repopulation by stimulating signal transduction and cell proliferation in neighbouring, non-apoptotic cells as reported recently. Tissue microarrays (TMAs) consisting of tumour tissue from 93 stage II and III colon cancer patients were analysed by immunohistochemistry. Surprisingly, patients with low levels of active Caspase-3 had an increased disease-free survival time. This was particularly pronounced in patients who received 5FU-based adjuvant CT. In line with this observation, lower serum levels of active Caspase-3 were found in patients with metastasised CRC who revealed stable disease or tumour regression compared with those with disease progression. The role of Caspase-3 in treatment responses was explored further in primary human tumour explant cultures from fresh patient tumour tissue. Exposure of explant cultures to 5FU-based CT increased the percentage of cells positive for active Caspase-3 and Terminal Deoxynucleotidyl Transferase dUTP Nick end Labelling (TUNEL), but also the expression of regeneration and proliferation markers β-Catenin and Ki-67, as well as cyclooxygenase-2 (COX-2). Of note, selective inhibition of Caspase-3 with Ac-DNLD-CHO, a selective, reversible inhibitor of Caspase-3, significantly reduced the expression of proliferation markers as well as COX-2. Inhibition of COX-2 with aspirin or celecoxib did not affect Caspase-3 levels but also reduced Ki-67 and β-Catenin levels, suggesting that Caspase-3 acted via COX-2 to stimulate cell proliferation and tissue regeneration. This indicates that low levels of active Caspase-3 may represent a

  4. A prospective evaluation of treatment with Selective Internal Radiation Therapy (SIR-spheres) in patients with unresectable liver metastases from colorectal cancer previously treated with 5-FU based chemotherapy

    To prospectively evaluate the efficacy and safety of selective internal radiation (SIR) spheres in patients with inoperable liver metastases from colorectal cancer who have failed 5FU based chemotherapy. Patients were prospectively enrolled at three Australian centres. All patients had previously received 5-FU based chemotherapy for metastatic colorectal cancer. Patients were ECOG 0–2 and had liver dominant or liver only disease. Concurrent 5-FU was given at investigator discretion. Thirty patients were treated between January 2002 and March 2004. As of July 2004 the median follow-up is 18.3 months. Median patient age was 61.7 years (range 36 – 77). Twenty-nine patients are evaluable for toxicity and response. There were 10 partial responses (33%), with the median duration of response being 8.3 months (range 2–18) and median time to progression of 5.3 mths. Response rates were lower (21%) and progression free survival shorter (3.9 mths) in patients that had received all standard chemotherapy options (n = 14). No responses were seen in patients with a poor performance status (n = 3) or extrahepatic disease (n = 6). Overall treatment related toxicity was acceptable, however significant late toxicity included 4 cases of gastric ulceration. In patients with metastatic colorectal cancer that have previously received treatment with 5-FU based chemotherapy, treatment with SIR-spheres has demonstrated encouraging activity. Further studies are required to better define the subsets of patients most likely to respond

  5. Identification of colorectal cancer patients with tumors carrying the TP53 mutation on the codon 72 proline allele that benefited most from 5-fluorouracil (5-FU) based postoperative chemotherapy

    Although postoperative chemotherapy is widely accepted as the standard modality for Dukes' stage C or earlier stage colorectal cancer (CRC) patients, biomarkers to predict those who may benefit from the therapy have not been identified. Previous in vitro and clinical investigations reported that CRC patients with wild-type p53 gene (TP53)-tumors benefit from 5-fluorouracil (5-FU) based chemotherapy, while those with mutated TP53-tumors do not. However, these studies evaluated the mutation-status of TP53 by immunohistochemistry with or without single-strand conformation polymorphism, and the mutation frequency was different from study to study. In addition, the polymorphic status at p53 codon 72, which results in arginine or proline residues (R72P) and is thought to influence the function of the protein significantly, was not examined. To evaluate the significance of the TP53 mutation as a molecular marker to predict the prognosis of CRC patients, especially those who received postoperative chemotherapy, we examined the mutation by direct sequencing from fresh CRC tumors and evaluated the R72P polymorphism of the mutated TP53 by a combined mutant allele- and polymorphic allele-specific polymerase chain reaction (PCR). The TP53 mutation occurred in 147 (70%) of 211 Japanese CRC tumors. The mutation was observed in 93 (63%) tumors on the R72 allele and in 54 (37%) tumors on the P72 allele. Although the alterations to TP53 have no prognostic significance for CRC patients overall, we found that Dukes' stage C CRC patients who did not receive postoperative chemotherapy and carried the mutated TP53-R72 showed significantly longer survival times than those with the mutated TP53-P72 when evaluated by overall survival (p = 0.012). Using a combined mutant allele- and polymorphic allele-specific PCR, we defined the codon 72 polymorphic status of the TP53 mutated allele in Japanese CRC patients. We raised a possibility that Dukes' stage C colorectal cancer

  7. A retrospective study of cardio toxicities induced by 5-Fluouracil (5-FU) and 5-FU based chemotherapy regimens in Pakistani adult cancer patients at Shaukat Khanum Memorial Cancer Hospital and Research Center

    Objective: To study cardio toxicities, especially bradycardia in cancer patients treated with 5-Fluouracil and 5-Fluouracil based chemotherapy regimens in Pakistani population. Methods: Data was extracted from the medical records of all diagnosed cancer patients at Shaukat Khanum Memorial Cancer Hospital and Research Center registered between January 2002 and December 2004 receiving 5- Fluouracil based chemotherapy regimens. The data was analysed retrospectively, including electrocardiogram and cardiac markers. Pearson's Correlation coefficient was calculated to see any possible correlation between 5-Fluouracil alone and 5-Fluouracil based regimens and cardiotoxicity, and other variables. Results: Symptomatic cardiotoxicity was observed in 60 (19.93%) out of 301 patients whose cases were part of the study. Bradycardia was the most common cardiotoxicity and was observed in 36 (11.96%) patients. Nine (2.99%) mortalities were also observed. The incidence of cardiotoxicity was not significantly different between the patients with and without pre-existing cardiovascular disease (p = 0.095) and having negative correlation -0.305. Cardio toxicities were more common with Continuous Infusion (CI) of 5-Fluouracil, radiotherapy concurrent with 5-Fluouracil and when 5-Fluouracil was used in combination with Cisplatinum (CDDP). Conclusion: Cardio toxicities were more prevalent when 5-Fluouracil was used along with concurrent radiotherapy and with Cisplatinum and when administered in continuous infusion pattern. Hence, 5-Fluouracil and 5-Fluouracil based chemotherapy regimens cause cardio toxicities, especially bradycardia, in a significant number of cancer patients in Pakistani population. (author)

  8. Adjuvant chemotherapy and cancer cure

    The use of chemotherapy as an adjuvant to surgery and/or radiotherapy is well founded in experimental tumor systems and appears to be effective in patients in some circumstances. It is clear from both clinical and experimental studies that (1) the dose is important, (2) the earlier chemotherapy is started after primary therapy the better, and (3) combination chemotherapy may be more effective than single-agent treatment. The better the estimation of risk of recurrence, the better the assessment of the risk-benefit ratio with adjuvant therapy. Salvage therapy as well as relative risk of recurrence are considerations in the choice of patients to be treated. Finally, some evidence is presented to indicate that alkylating agents may not be necessary in combination regimens for adjuvant therapy if effective antimetabolite combinations are available

  9. [Adjuvant chemotherapy of adults soft tissue sarcomas].

    Bui-Nguyen, B; Italiano, A; Delva, F; Toulmond, M

    2010-06-01

    The main progress in the management of soft tissue sarcomas have been obtained in the field of local control. Although the main evolutive, vital, risk of these diseases is metastatic dissemination, efficacy of adjuvant chemotherapy remains a controversial issue. Thus, adjuvant chemotherapy cannot be considered as a standard for any situation. The last results of clinical trials, meta-analysis and population studies are presented and discussed in this article. New therapeutic strategies are to be developed to prevent metastases in soft tissue sarcomas. This needs a better understanding of the biology of those tumors, of metastases risk factors and of the determinants of systemic therapies efficacy in these tumors. PMID:20547481

  10. Impact of adjuvant chemotherapy for gliomatosis cerebri

    Gliomatosis cerebri (GC) is characterized by a diffuse infiltration of tumor cells throughout CNS, however, few details are available about the chemotherapeutic effect on GC. The aim of this study was to investigate its clinical course and to determine the efficacy of chemotherapy for GC. Between Jan. 1999 and Dec. 2004, 37 GC patients were diagnosed by biopsy and treated with radiotherapy in a single institution. To determine the efficacy of chemotherapy for GC, we retrospectively reviewed their clinical courses. The study cohort was divided into 2 groups, those with and without receiving post-radiotherapy adjuvant chemotherapy such as temozolomide or nitrosourea-based chemotherapy. Nineteen patients with adjuvant chemotherapy were assigned to the chemotreatment group and 18 with radiotherapy alone were assigned to the control group. Mean survival for chemotreatment group and control group were 24.2 and 13.1 months, respectively (p = 0.045). Time to progression for these groups were 16.0 and 6.0 months, respectively (p = 0.007). Overall review of the clinical course of patients with GC provided that early appearance of new contrast-enhancing lesions within 6 months from the initial diagnosis and higher histological grade were closely associated with poor survival (p < 0.001 and p = 0.008). Adjuvant chemotherapy following radiotherapy could prolong the survival in patients with GC. In addition, newly developed contrast-enhanced lesions on the follow-up MR images indicate the progression of GC

  11. Adjuvant Bidirectional Chemotherapy Using an Intraperitoneal Port

    Full Text Available Cytoreductive surgery (CRS and hyperthermic intraperitoneal chemotherapy (HIPEC have been established as treatment options for patients with peritoneal metastases or peritoneal mesothelioma. However, this novel treatment strategy remains associated with a large percentage of local-regional treatment failures. These treatment failures are attributed to the inadequacy of HIPEC to maintain a surgical complete response. Management strategies to supplement CRS and HIPEC are indicated. A simplified approach to the intraoperative placement of an intraperitoneal port for adjuvant bidirectional chemotherapy (ABC was devised. Four different chemotherapy treatment plans were utilized depending upon the primary site of the malignancy. Thirty-one consecutive patients with an intraoperative placement of the intraperitoneal port were available for study. The incidence of adverse events that caused an early discontinuation of the bidirectional chemotherapy occurred in 75% of the 8 patients who had an incomplete cytoreduction and in 0% of patients who had a complete cytoreduction. All of the patients who had complete cytoreduction completed at least 5 of the scheduled 6 bidirectional chemotherapy treatments. Adjuvant bidirectional chemotherapy is possible following a major cytoreductive surgical procedure using a simplified method of intraoperative intraperitoneal port placement.

  12. Neoadjuvant and Adjuvant Chemotherapy of Cervical Cancer.

    Mallmann, Peter; Mallmann, Christoph

    2016-01-01

    Neoadjuvant chemotherapy is indicated in patients who can tolerate the side effects of a chemotherapy and with preoperative presentation of one of the following clinical risk situations: bulky disease with a maximal tumor diameter of > 4 cm, suspicious lymph nodes in magnetic resonance imaging (MRI), computed tomography (CT) scan or endosonography, histopathologically confirmed lymph node metastasis, or histopathologically documented risk factors such as G3 and L1V1. A neoadjuvant chemotherapy followed by surgery should be performed with cisplatin at a dosage of > 25 mg/m2 per week and an application interval of < 14 days. The previously published data suggests an improved rate of complete resection and reduced incidences of positive lymph nodes and parametric infiltration. Accordingly, the percentage of patients in need for adjuvant radiochemotherapy after operation can be significantly reduced. Some studies demonstrated a prolongation of progression-free and overall survival. Following the previously published studies, adjuvant chemotherapy after operation or after radiochemotherapy has no significant effect on the overall survival and, following the current guidelines, should be avoided.

  13. Adjuvant chemotherapy for soft tissue sarcoma.

    Casali, Paolo G

    2015-01-01

    Adjuvant chemotherapy is not standard treatment in soft tissue sarcoma (STS). However, when the risk of relapse is high, it is an option for shared decision making with the patient in conditions of uncertainty. This is because available evidence is conflicting, even if several randomized clinical trials have been performed for 4 decades and also have been pooled into meta-analyses. Indeed, available meta-analyses point to a benefit in the 5% to 10% range in terms of survival and distant relapse rate. Some local benefit also was suggested by some trials. Placing chemotherapy in the preoperative setting may help gain a local advantage in terms of the quality of surgical margins or decreased sequelae. This may be done within a personalized approach according to the clinical presentation. Attempts to personalize treatment on the basis of the variegated pathology and molecular biology of STS subgroups are ongoing as well, according to what is done in the medical treatment of advanced STS. Thus, decision making for adjuvant and neoadjuvant indications deserves personalization in clinical research and in clinical practice, taking profit from all multidisciplinary clinical skills available at a sarcoma reference center, though with a degree of subjectivity because of the limitations of available evidence.

  15. Adjuvant chemotherapy in early breast cancer.

    these CMF regimens has not been compared within the context of a randomised trial. Shifting from the 77B's classic CMF regimen to the 82B four-weekly IV regimen or the 89B three-weekly IV regimen was associated with a 30% increased risk of a DFS event in a multivariate analysis of a population-based cohort study. Furthermore, the four-weekly regimen used in 82B was associated with a 40% increase in mortality. The strengths of the design include identical selection criteria, uniform and prospective registration of treatment, tumour and patient characteristics. Caution is still required due to the non-experimental design of the comparison. Another finding was a substantial difference in the risk of amenorrhoea; and while 15% of patients aged 40 or younger in 77B had regular menses throughout chemotherapy, the corresponding percentage was 37 in 82B and 47 in 89B. The DBCG in collaboration with a Swedish and a Dutch centre participating in the DBCG trial 89B compared CMF with ovarian ablation in premenopausal high-risk breast cancer patients with ER-positive tumours. No significant differences were found in DFS or OS in the preplanned analysis, suggesting that the benefits of CMF may, at least in part, be explained by ovarian suppression in premenopausal patients with ER-positive tumours. However, these results are not clinically useful by themselves as other chemotherapy regimens have been more efficacious, and knowledge is still lacking regarding the benefits from adding ovarian suppression to chemotherapy plus tamoxifen. The results from the DBCG 77B and 82C are in accordance with other large adjuvant trials and the EBCTCG meta-analyses. The benefits obtained with any individual anticancer drug are largely determined by the cancer (somatic) genome; and by being a molecular target of anthracyclines, TOP2A aberrations could obviously be associated with cancer drug benefits. In the DBCG 89D, a significant heterogeneity was observed between a beneficial effect on DFS and OS

  17. Adjuvant endocrine and chemotherapy for early breast cancer

    Objective: Present the results of the 1995 World Overview which will be held in Oxford England two weeks before ASTRO. Discuss the interpretation and application of these results. Review current research topics on the use of adjuvant endocrine and chemotherapy for early breast cancer. The survival benefits from adjuvant chemotherapy in premenopausal women and adjuvant tamoxifen in postmenopausal women are well established. Each will reduce the annual odds of death by about 25% resulting in a 10 year survival difference of 8-10%. By the time of this presentation, the results of the 1995 Adjuvant Therapy Overview should be with 10+ years of follow-up, and if possible these will be summarized. Current efforts to improve on previous results are focused on the following areas: Optimal chemotherapy dose. Decreasing dose will compromise patient survival. It is not as certain that increasing dose will have as much impact in improving survival. The NSABP was unable to demonstrate an improvement in survival by modestly increasing the dose of cyclophosphamide alone. However, recent results of a Canadian study of CEF (cyclophosphamide, epidoxorubicin, and 5-fluorouracil) and an Intergroup trial of an intense 16 week polychemotherapy program keep alive the possibility that dose escalation is still a very important question. An NSABP trial evaluating even greater cyclophosphamide dose escalation, an Intergroup evaluation of different doxorubicin doses, and two Intergroup trials evaluating very high dose chemotherapy and bone marrow transplantation should provide definitive evidence regarding the importance of dose. Drug sequence. A study from Milan suggests that initial treatment with single agent doxorubicin followed by CMF will be superior to alternating doxorubicin and CMF. This has not been confirmed yet, and the reason for increased benefit from such a sequence is not entirely clear. This concept is being explored further in an Intergroup trial comparing four cycles of

  20. Postoperative adjuvant radiotherapy and 5-fluorouracil chemotherapy for rectal carcinoma

    Postoperative combined modality therapy with radiotherapy and 5-fluorouracil (5FU) chemotherapy is an effective adjuvant approach that reduces locoregional and distant metastatic disease in patients with high-risk rectal carcinoma. However, this approach results in a treatment regimen of at least 6 months' duration. The present prospective study investigates the integration of radiotherapy and 5FU chemotherapy in a protocol designed to minimize toxicity and reduce the overall treatment time. A total of 40 patients with TNM stage 11 or 111 disease receives postoperative radiotherapy at four fractions per week with weekly 5FU bolus injections delivered on the fifth non radiotherapy day. Patients also received systemic chemotherapy with leucovorin both before and after pelvic irradiation, with the total treatment duration extending for only 18 weeks. Patients were able to complete radiotherapy in 90% of cases, while the delivery of full-dose chemotherapy was achievable in the vast majority. The incidence of haematologic and gastrointestinal toxicities requiring the cessation of treatment was acceptable. With a median follow-up of 20.9 months among surviving patients, the estimated progression-free and overall survival at 2 years were 71% and 79%, respectively.

  2. [Recent Status of Postoperative Adjuvant Chemotherapy after Completely Resected Lung Cancer].

    Naito, Masahito; Tsuboi, Masahiro

    2016-02-01

    Several landmark study elucidated that adjuvant cisplatin-based chemotherapy for stage II-IIIA non-small cell lung cancer (NSCLC)patients after appropriate surgical resection can significantly improve 5-year survival rate. Meta-analysis of modern cisplatin based adjuvant chemotherapy trial confirmed this benefit. Furthermore, in Japan, large randomized trial and metaanalysis assessing the efficacy of uracil-tegafur(UFT)for stage I patients with completely resected NSCLC reported that UFT can significantly improve 5-year survival rate. Meta-analysis of subgroup assessed that effectiveness of UFT for stage I NSCLC patients with a tumor lager than 2 cm. According to these evidence, cisplatin-based adjuvant chemotherapy for stage II-III A NSCLC and UFT for stage I NSCLC patients with a tumor lager than 2 cm are used standard postoperative adjuvant chemotherapy in Japan. In recent year, it is presumed that personalized care will be necessary to re-evaluate strategies for postoperative adjuvant chemotherapy of lung cancer. Considering histological subtype of lung cancer, several randomize trial for postoperative adjuvant chemotherapy with non-squamous NSCLC or high neuroendocrine tumor of lung are ongoing. In addition, recent studies of biological research indicate that some tumor marker such as ERCC1 may had a predictive value for selecting patients who will derive the benefit from adjuvant chemotherapy.

  3. Induction chemotherapy followed by radiotherapy and adjuvant chemotherapy for locally advanced nasopharyngeal carcinoma treated

    Objective: To summarize the efficacy and toxicities of induction chemotherapy followed by radiotherapy and adjuvant chemotherapy in the treatment of locally advanced nasopharyngeal carcinoma (NPC). Methods: From Oct. 1997 to Nov. 2000, 77 patients with histologically proven locally advanced NPC, staged according to the Fuzhou stage classification, were retrospectively studied. Before radical radio- therapy, the patients received 1-3 cycles cisplatin(PDD) 20 mg/m2 on Days 1-3 and fluorouracil(5-Fu) 500 nag/ma on Days 1-3 repeated every two weeks. Sixty-two patients also received calcium folinate (CF) 100 mg/m2 on Days 1-3. Two to four cycles of adjuvant chemotherapy was given 21 days after the completion of radiotherapy. All patients received radical radiotherapy by 60 Co to the nasopharynx and neck with a total dose of 64-78 Gy at 1.8-2.0 Gy per fraction over 7.0-7. 5 weeks to the primary site. The dose to the lymph nodes was 60-68 Gy. After-loading radiotherapy was given to the residual disease in 1 patient (20 Gy in 2 fractions). Results: The median follow-up was 60 months (ranged from 3 to 103 months). The 5-year overall urvival rate (OS), disease-free survival rate (DFS), relapse-free survival rate (RFS) and distant metastasis-free survival rate (DMSF) were 68%, 58%, 81% and 75%. The patients who received more than 3 cycles of chemotherapy or not had no significant effects on the OS (χ2=0.05, P=0.831). The incidence of grade 3 or 4 acute side-effects of radiotherapy was vomiting 1%, leukopenia 3%, mucositis 23% and skin reaction 5%, all of which eventually resolved. The most frequent late toxicities were hearing impairment (51% ). Patients with more than 3 cycles chemotherapy were more likely to have late hearing loss (z=2.06, P=0.039). Only one patient had radiation-induced brain damage. Conclusions: Induction chemo- therapy, radiotherapy and adjuvant chemotherapy for locally advanced nasopharyngeal carcinoma would result in a comparable outcome, but may

  7. Magnetic nanoparticle hyperthermia as an adjuvant cancer therapy with chemotherapy

    Petryk, Alicia Ailie

    Magnetic nanoparticle hyperthermia (mNPH) is an emerging cancer therapy which has shown to be most effective when applied in the adjuvant setting with chemotherapy, radiation or surgery. Although mNPH employs heat as a primary therapeutic modality, conventional heat may not be the only cytotoxic effect. As such, my studies have focused on the mechanism and use of mNPH alone and in conjunction with cisplatinum chemotherapy in murine breast cancer cells and a related in vivo model. MNPH was compared to conventional microwave tumor heating, with results suggesting that mNPH (mNP directly injected into the tumor and immediately activated) and 915 MHz microwave hyperthermia, at the same thermal dose, result in similar tumor regrowth delay kinetics. However, mNPH shows significantly less peri-tumor normal tissue damage. MNPH combined with cisplatinum also demonstrated significant improvements in regrowth delay over either modality applied as a monotherapy. Additional studies demonstrated that a relatively short tumor incubation time prior to AMF exposure (less than 10 minutes) as compared to a 4-hour incubation time, resulted in faster heating rates, but similar regrowth delays when treated to the same thermal dose. The reduction of heating rate correlated well with the observed reduction in mNP concentration in the tumor observed with 4 hour incubation. The ability to effectively deliver cytotoxic mNPs to metastatic tumors is the hope and goal of systemic mNP therapy. However, delivering relevant levels of mNP is proving to be a formidable challenge. To address this issue, I assessed the ability of cisplatinum to simultaneously treat a tumor and improve the uptake of systemically delivered mNPs. Following a cisplatinum pretreatment, systemic mNPs uptake was increased by 3.1 X, in implanted murine breast tumors. Additional in vitro studies showed the necessity of a specific mNP/ Fe architecture and spatial relation for heat-based cytotoxicity in cultured cells.

    Adjuvant chemotherapy is often needed to achieve adequate breast cancer control. The increasing popularity of immediate breast reconstruction (IBR) raises concerns that this procedure may delay the time to adjuvant chemotherapy (TTC), which may negatively impact oncological outcome. The current systematic review aims to investigate this effect. During October 2014, a systematic search for clinical studies was performed in six databases with keywords related to breast reconstruction and chemot...

  9. Adjuvant chemotherapy in stage I breast cancer. More harm than benefit.

    Mueller, C B

    1993-01-01

    Clinical trials of adjuvant chemotherapy for breast cancer have shown a prolonged disease-free interval but no improvement in survival. This review of the evidence indicates that adjuvant therapy induces an antineoplastic drug resistance that makes "salvage" therapy less effective. The benefit that is seen only in group statistics, not in an individual, must be weighed against the harm an individual incurs from the chemotherapy.

    1999-01-01

    Objective: To evaluate the efficacy of adjuvant chemotherapy after radical surgery for non-small cell lung cancer (NSCLC). Methods: Seventy patients with NSCLC (stage Ⅰ-Ⅲ) undergone radical surgery were randomized into two groups: 35 patients received adjuvant chemotherapy with cyclophosphamide (CTX)300 mg/m2, vincristine (VCR) 1.4% mg/m2, adriamycin (ADM) 50 mg/m2, lomustine (CCNU) 50 mg/m2 d1,cisplatin (DDP) 20 mg/m2, d1-5, for 4 cycles, and followed by oral Ftorafur (FT-207) 600-900 mg/d for 1year (adjuvant chemotherapy group). The other 35patients received surgical treatment only (surgery group). Results: The overall 5-year survival rate was 48.6% in the adjuvant chemotherapy group, and 31.4%in the surgery group, respectively. The difference between the two groups was not statistically significant (P>0.05). The 5-year survival rate of patients in stage Ⅲwas 44.0% and 20.8% received surgery with and without adjuvant chemotherapy, respectively. The difference between the two groups was statistically significant (P<0.025). The 5-year survival rate of patients in stage Ⅰ-Ⅱ in the two groups was 60.0% and 54.5%, respectively (P>0.75). Conclusion: Postoperative adjuvant chemotherapy in NSCLC can improve survival, for those patients in stage Ⅲ, it suggests significantly 5-year survival rate in the adjuvant chemotherapy group was higher than that in the surgery alone group.

  15. ERCC1 as a biomarker for bladder cancer patients likely to benefit from adjuvant chemotherapy

    The role of adjuvant chemotherapy and the value of molecular biomarkers in bladder cancer have not been determined. We aimed to assess the predictive and prognostic values of excision repair cross-complementation 1 (ERCC1) in identifying appropriate patients who may potentially benefit from adjuvant chemotherapy for bladder cancer. A retrospective analysis was performed on 93 patients with completely resected transitional cell carcinoma of the bladder. ERCC1 expression was assessed by immunohistochemistry. ERCC1 expression was analyzed in 57 patients treated with adjuvant gemcitabine plus cisplatin chemotherapy and 36 who were not treated. Among 93 patients, ERCC1 expression was positive in 54 (58.1%) and negative in 39 (41.9%). ERCC1 positivity was significantly associated with longer survival (adjusted hazard ratio for death, 0.12, 95% confidence interval [CI] 0.014-0.99; P = 0.049) in the group without adjuvant chemotherapy while ERCC1 positivity was associated with shorter survival among patients who have received adjuvant chemotherapy (adjusted hazard ratio for death, 2.64; 95% CI 1.01-6.85; P = 0.047). Therefore, clinical benefit from adjuvant chemotherapy was associated with ERCC1 negativity as measured by overall survival (test for interaction, P = 0.034) and by disease-free survival (test for interaction, P = 0.20). Among patients with completely resected transitional cell carcinoma of the bladder, those with ERCC1-negative tumors seemed to benefit more from adjuvant gemcitabine plus cisplatin chemotherapy than those with ERCC1-positive tumors. Future prospective, randomized studies are warranted to confirm our findings

    2012-01-01

    Full Text Available Abstract Background Increased health care costs have made it incumbent on health-care facilities and physicians to demonstrate both clinical and cost efficacy when recommending treatments. Though studies have examined the cost-effectiveness of adjuvant goserelin with radiotherapy for locally advanced prostate cancer, few have compared the cost-effectiveness of adjuvant goserelin to adjuvant chemotherapy alone in premenopausal breast cancer. Methods In this retrospective study at one hospital, the records of 152 patients with stage Ia to IIIa ER + breast cancer who received goserelin or chemotherapy were reviewed. Survival analysis was assessed by the Kaplan-Meier method. Patients were interviewed to evaluate their quality of life using the European Organization for Research and Treatment Quality of Life questionnaire (EORTC-QLQ-C30, version 4.0, and to obtain the utility value by the standard gamble (SG and visual scale (VS methods. Total medical cost was assessed from the (National Health Insurance NHI payer's perspective. Results Survival at 11 years was significantly better in the groserelin group (P Conclusions Goserelin therapy results in better survival and higher utility-weighted life-years, and is more cost-effective than TC or TEC chemotherapy.

  17. Adjuvant chemotherapy (Nedaplatin/UFT) after radiotherapy for locallu advanced head and neck cancer

    To evaluate the toxicity and efficacy of adjuvant chemotherapy after radiotherapy for patients with locally advanced head and neck squamous cancer, 40 patients, previously untreated (6 with stage III and 34 with stage IV; 26 with resectable, 10 with unresectable and 4 patients with inoperable) were treated with radiotherapy followed by adjuvant chemotherapy (Nedaplatin /tegafur-uracil (UFT)) at our outpatient clinic. The primary site was identified in the larynx or hypopharynx in 15, oral cavity or oropharynx in 11, sinuses in 6, nasopharynx in 4, unknown primary in 3, and parotis in 1 patient. Treatment consisted of 6 courses of Nedaplatin 80 mg/m2 repeated at 4 weeks intervals, and one-year oral administration of UFTE 400mg/day, after radiotherapy. Toxicities included leukopenia (grade 3, 20.5%, grade 4, 2.6%), thrombocytopenia (grade 3, 7.7%). There was one death due to gastric ulcer. Twenty-five patients (62.5%) received 6 courses of adjuvant chemotherapy. Two-year overall survival rate was 100% for stage III and 61.1% for stage IV. Over the same period, the progression-free survival rate was 83.3% for stage III and 46.1% for stage IV. 85.7% of complete response (CR) (12/14 patients) and 63.6% of partial response (PR) (14/22 patients) to radiotherapy showed that the effect of radiotherapy was maintained during adjuvant chemotherapy. If the effect of radiotherapy was maintained during adjuvant chemotherapy, the two-year progression free survival rate was not different between 81.8% for CR to radiotherapy and 81.3% for PR. The rate of distant failure was 2.5%, which was lower than that citedin previous reports. This adjuvant chemotherapy regimen is tolerable at outpatient clinics and might suppress distant metastasis after radiotherapy. (author)

    The standard treatment in children with average-risk medulloblastoma (MB) is reduced-dose radiotherapy (RT) followed by chemotherapy. However, in adults, there is no agreement on the use of adjuvant chemotherapy. We performed a retrospective analysis of adult MB patients with average-risk disease, defined as no postsurgical residual (or ≤1.5 cm(2)) and no metastatic disease (M0). Main inclusion criteria were: age >16 years, post-surgical treatment with craniospinal irradiation with or without adjuvant chemotherapy (cisplatin and etoposide ± cyclophosphamide). From 1988 to 2012 were accrued 43 average-risk MB patients treated with surgery and adjuvant RT. Fifteen (34.9 %) patients received also chemotherapy: 7 before RT, 5 after RT, and 3 before and after RT. Reasons to administer chemotherapy were presence of residual disease (even if ≤1.5 cm) and delay in RT. After a median follow up time of 10 years (range: 8-13), median survival was 18 years (95 % CI 9-28) in patients who receive RT alone, and was not reached in patients treated with RT plus chemotherapy. The survival rates at 5, 10 and 15 years were 100 %, 78.6 % (95 % CI 60.0-97.2 %) and 60.2 % (95 % CI 36.9-83.5 %), in patients treated with RT alone, and 100, 100 and 100 %, in patients treated with RT plus chemotherapy (p = 0.079). Our findings suggest a role for adjuvant chemotherapy in the treatment of average-risk MB adult patients. Further improvements might drive to add chemotherapy in average-risk setting with less favourable biological signatures (i.e., non-WNT group). PMID:26940908

  19. Is It Possible to Shorten the Duration of Adjuvant Chemotherapy for Locally Advanced Rectal Cancer?

    Abstract The long duration of 4 months of postoperative adjuvant chemotherapy is currently recommended for locally advanced rectal cancer after preoperative chemoradiation and surgery. Whether a short duration could be applied in these patients is unknown. So, the purpose of this study is to evaluate the effects on prognosis based on different durations of adjuvant chemotherapy for rectal cancer. We performed a retrospective study of 200 rectal cancer patients who were treated with preoperative chemoradiation and were pathologically graded as ypII and ypIII stages between March 2003 and May 2012. All patients were divided into 2 groups according to the median duration of adjuvant chemotherapy of 2 months. Overall survival (OS) and disease-free survival (DFS) were compared between patients with duration shorter and longer than 2 months in the whole group and subgroups of ypII and ypIII. Recurrence patterns were also analyzed in all subgroups. Multivariate analysis was performed to explore clinical factors that were significantly associated with DFS, local recurrence-free survival, and distant metastasis-free survival. In subgroup of ypII stage, the 5-year OS and DFS were similar between patients in long and short durations of adjuvant chemotherapy. For patients of ypIII stage, although no significant difference was found in OS between patients in short and long durations, DFS was showed to be higher in the group of long duration. Further analysis showed that longer duration of adjuvant chemotherapy could lead to improved control of distant metastasis and no impact on local control. Multivariable analysis indicated that long duration of adjuvant chemotherapy is significantly associated with longer distant metastasis-free survival in patients with ypIII stage, but not in those with ypII stage. A long duration of at least 2 months of postoperative adjuvant chemotherapy is necessary for patients with ypIII stage, whereas it may not be absolutely appropriate for those

  20. Adjuvant chemotherapy in soft tissue sarcomas…Conflicts, consensus, and controversies

    Jyoti Bajpai

    2016-01-01

    Full Text Available Soft tissue sarcomas (STSs are an uncommon and diverse group of more than 50 mesenchymal malignancies. Each of these histologic subtypes represents a unique disease with distinct biologic behavior and varying sensitivity to chemotherapy. The judicious use of adjuvant/neoadjuvant chemotherapy along with surgery and radiation in the treatment of localized STS has a role in improving patient outcomes by decreasing local and distant recurrences. There is evidence that the use of adjuvant chemotherapy to a mixed cohort of chemo sensitive and insensitive sarcoma subtypes results in limited benefit. Therefore, it is of paramount importance to identify the subpopulation with high metastatic potential and to identify effective histology-specific treatment options to these patients. Present perspective, will focus on the rationale for adjuvant chemotherapy in sarcoma, with emphasis on the histology driven chemotherapy. It will outline key therapeutic opportunities and hurdles in adjuvant medical treatment of sarcoma, focusing on specific subtypes that are on the verge of new breakthroughs, as well as those in which promise has not lived up to expectations.

  4. Pilot study of bone mineral density in breast cancer patients treated with adjuvant chemotherapy

    Headley, J. A.; Theriault, R. L.; LeBlanc, A. D.; Vassilopoulou-Sellin, R.; Hortobagyi, G. N.

    1998-01-01

    The objective of this cross-sectional study was to determine lumbar spine bone mineral density (BMD) in breast cancer patients previously treated with adjuvant chemotherapy. Sixteen of 27 patients who received adjuvant chemotherapy became permanently amenorrheic as a result of chemotherapy. BMD was measured at the lumbar spine using dual energy X-ray absorptiometry (DEXA). Chemotherapy drugs and dosages along with a history of risk factors for reduced bone density including activity level, tobacco and/or alcohol use, metabolic bone disease, family history, and hormone exposure were identified. Results showed that women who became permanently amenorrheic as a result of chemotherapy had BMD 14% lower than women who maintained menses after chemotherapy. Chemotherapy-treated women who maintained ovarian function had normal BMD. This study suggests that women who have premature menopause as a result of chemotherapy for breast cancer are at increased risk of bone loss and may be at risk for early development of osteoporosis. Women who maintain menses do not appear to be at risk for accelerated trabecular bone loss.

  5. Retrospective analysis on prognostic impact of adjuvant chemotherapy in the patients with advanced and resectable oral squamous cell carcinoma

    The effect of adjuvant chemotherapy on oral squamous cell carcinoma (SCC) is unclear mainly because there have been a few studies which evaluate the efficacy of adjuvant chemotherapy. The purpose of this retrospective study was to analyze the efficacy of adjuvant chemotherapy in the patients with advanced and resectable oral SCC. Forty-one patients in whom advanced SCC (stage III and IV) was completely removed were included in this study. The impact of multiple variables including T-classification, degree of differentiation, mode of invasion, number and level of cervical metastatic node, pre- and post-operative radiation therapy, neoadjuvant chemotherapy, and adjuvant chemotherapy on survival and control of local relapse or distant metastasis was assessed using the stepwise Cox proportional hazards model. The level of neck node metastasis (p<0.02) was a significant independent predictor for cause-specific survival and adjuvant chemotherapy was of borderline significance (p=0.07). The number of neck node metastasis (p<0.01) and adjuvant chemotherapy (p<0.01) were significantly related with disease free survival. The results of this retrospective study suggested that adjuvant chemotherapy had a significant benefit in improving disease free survival. (author)

Hospital Munich, LMU (Germany); Schmidt, Michael [Inst. for Biometry and Epidemiology, Univ. Hospital Munich, LMU (Germany); Hoelzel, Dieter [Tumor Registry Munich, Univ. Hospital Munich, LMU (Germany)

    2010-07-15

    Background and purpose: for definitive radiochemotherapy, 5-fluorouracil/cisplatin protocols have been considered the standard of care for esophageal carcinoma over the last 2 decades. By contrast, most patients treated at the University Hospital, LMU Munich, Germany, received 5-fluorouracil/mitomycin C. The objective of this retrospective analysis was to determine the value of 5-fluorouracil/mitomycin-C-based therapy. Patients and methods: tumor stage, treatment received, and outcome data of patients treated for esophageal cancer between 1982 and 2007 were collected; endpoint of the analysis was overall survival. Results: 298 patients with inoperable cancer of the esophagus were identified (16.8% adenocarcinoma, 77.5% squamous cell carcinoma). At diagnosis, 61.7% (184/298) had UICC stage III-IV, 54.4% (162/298) positive lymph nodes, and 26.5% (79/298) metastatic disease. 74.5% of all patients (222/298) received radiation doses between 55 and 65 Gy, 65.8% (196/298) were subjected to concomitant chemotherapy. The median follow-up period (patients alive) was 4.1 years. A significant increase of overall survival (p < 0.0001) in the radiochemotherapy versus the radiotherapy=alone group was observed. 52% (102/196) in the 5-fluorouracil/mitomycin C group had tumor stages comparable to the RTOG 85-01 study cohort (T1-3 N0-1 M0). The median survival in this subgroup was 18.2 months, 3- and 5-year survival rates were 22.7% (21/102) and 15.0% (13/102), respectively. Conclusion: despite being nominally inferior to platinum-based radiochemotherapy, the overall survival rates are in a similar range. Thus, the mitomycin-C-based radiochemotherapy approach may considered to be as effective as the standard therapy. However, there is no randomized trial available in order to prove the equality.

  8. Influence of radiotherapy on the dose of adjuvant chemotherapy in early breast cancer

    399 patients with early breast cancer were randomly allocated to treatment by either modified radical mastectomy or lumpectomty and radiotherapy. 169 had histologically involved axillary nodes and were randomised to receive either adjuvant cytotoxic chemotherapy (76 patients) or no systemic adjuvant treatment (93 patients). Chemotherapy comprised a combination of oral cyclophosphamide and intravenous methotrexate and 5-fluorouracil (CMF) for 12 cycles over one year. Patients in the mastectomy group received a significantly higher percentage of the planned chemotherapy dose compared with those in the radiotherapy group (median 85% v. 71% p < 0.05). Patients treated with radiotherapy were more frequently nauseated and developed more severe alopecia, but these differences were not statistically significant. At median follow-up of 37 months the relapse-rate and pattern of relapse were similar in both groups of patients receiving CMF. (author). 11 refs.; 5 tabs

  11. Preoperative radio-chemotherapy for rectal cancer: Forecasting the next steps through ongoing and forthcoming studies

    Protracted preoperative radio-chemotherapy with a 5-FU-based scheme, or a short course of preoperative radiotherapy without chemotherapy, are the standard neo-adjuvant treatments for resectable stage II-III rectal cancer. Local failure rates are low and reproducible, between 6 and 15% when followed with a 'Total Meso-rectal Excision'. Nevertheless, the therapeutic strategy needs to be improved: distant metastatic recurrence rates remain stable around 30 to 35%, while both sphincter and sexual sequels are still significant. The aim of the present paper was to analyse the ongoing trials listed on the following search engines: the Institut National du Cancer in France, the National Cancer Institute and the National Institute of Health in the United States, and the major cooperative groups. Keywords for the search were: 'rectal cancer', 'preoperative radiotherapy', 'phase II-III', 'preoperative chemotherapy', 'adjuvant chemotherapy' and 'surgery'. Twenty-three trials were selected and classified in different groups, each of them addressing a question of strategy: (1) place of adjuvant chemotherapy; (2) optimization of preoperative radiotherapy; (3) evaluation of new radiosensitization protocols and/or neo-adjuvant chemotherapy; (4) optimization of techniques and timing of surgery; (5) place of radiotherapy for non resectable or metastatic tumors.

    Objective:Survival and treatment of patients with microinvasive breast cancer (MIBC) remain controversial. In this paper, we evaluated whether adjuvant chemotherapy is necessary for patients with MIBC to identify risk factors influencing its prognosis and decide the indication for adjuvant chemotherapy. Methods:In this retrospective study, 108 patients with MIBC were recruited according to seventh edition of the staging manual of the American Joint Committee on Cancer (AJCC). The subjects were divided into chemotherapy and non-chemotherapy groups. We compared the 5-year disease-free survival (DFS) and overall survival (OS) rates between groups. Furthermore, we analyzed the factors related to prognosis for patients with MIBC using univariate and multivariate analyses. We also evaluated the impact of adjuvant chemotherapy on the prognostic factors by subgroup analysis after median follow-up time of 33 months (13-104 months). Results:The 5-year DFS and OS rates for the chemotherapy group were 93.7% and 97.5%, whereas those for the non-chemotherapy group were 89.7% and 100%. Results indicate that 5-year DFS was superior, but OS was inferior, in the former group compared with the latter group. However, no statistical significance was observed in the 5-year DFS (P=0.223) or OS (P=0.530) rate of the two groups. Most relevant poor-prognostic factors were Ki-67 overexpression and negative hormonal receptors. Cumulative survival was 98.2%vs. 86.5% between low Ki-67 (≤20%) and high Ki-67 (>20%). The hazard ratio of patients with high Ki-67 was 16.585 [95% confidence interval (CI), 1.969-139.724;P=0.010]. Meanwhile, ER(-)/PR(-) patients with MIBC had cumulative survival of 79.3% compared with 97.5% for ER(+) or PR(+) patients with MIBC. The hazard ratio for ER(-)/PR(-) patients with MIBC was 19.149 (95% CI, 3.702-99.057;P<0.001). Subgroup analysis showed that chemotherapy could improve the outcomes of ER(-)/PR(-) patients (P=0.014), but not those who overexpress Ki-67 (P=0

  13. Outcomes of Adjuvant Chemoradiation After Pancreaticoduodenectomy With Mesenterico-Portal Vein Resection for Adenocarcinoma of the Pancreas

    Purpose: Surgery followed by chemotherapy and radiation (CRT) offers patients with pancreatic adenocarcinoma a chance for extended survival. In some patients, however, resection is difficult because of vascular involvement by the carcinoma, necessitating resection and grafting of the mesenterico-portal vessels. The purpose of this study was to compare outcomes between pancreaticoduodenectomy (PD) with and without mesenterico-portal vein resection (VR) in patients receiving adjuvant CRT for pancreatic adenocarcinoma. Methods and Materials: Between 1993 and 2005, 160 patients underwent PD with 5-FU-based adjuvant CRT followed by maintenance chemotherapy at the Johns Hopkins Hospital; 20 (12.5%) of the 160 underwent VR. Clinical outcomes, including median survival, overall survival, and complication rates were assessed for both groups. Results: Patients who underwent VR had significantly longer operative times (p = 0.009), greater intraoperative blood loss (p = 0.01), and longer postoperative lengths of stay (p = 0.03). However, postoperative morbidity, median survival, and overall survival rates were similar between the two groups. Most patients (70%) from both groups were able to complete CRT, and a subgroup analysis demonstrated no appreciable differences in terms of complications. None of the VR patients who received adjuvant CRT developed veno-occlusive disease or graft failure/leakage. Conclusion: In a cohort of patients treated with adjuvant 5-FU-based CRT at the Johns Hopkins Hospital, having a VR at the time of PD resulted in similar complication rates and survival. These data support the feasibility and safety of adjuvant CRT in patients undergoing VR at the time of PD.

  15. Adjuvant chemotherapy, a valuable alternative option in selected patients with cervical cancer.

    Shuang Li

    Full Text Available Radiotherapy is the standard treatment for cervical cancer, but causes radiotherapy-induced complications. Recently, chemotherapy has been more extensively utilized. Here, we perform a large-scale comparison of chemotherapy and radiotherapy. From 2002 to 2008, 2,268 patients were grouped according to adjuvant radiotherapy or chemotherapy before and/or after surgery, and we compared the 5-year overall survival (OS and disease-free survival (DFS rates, recurrence rates, side effects, quality of life (QoL, and sexual activity. There were no significant differences between the treatment groups for the 5-year OS and DFS rates (OS: p = 0.053, DFS: p = 0.095, although marginally improved outcomes were observed in the chemotherapy group (OS: 86.5% vs. 82.8%; DFS: 84.5% vs. 81.4%. However, patients with early-stage disease, clinical response, and younger age had increased 5-year OS and DFS rates following chemotherapy compared to radiotherapy (p<0.05. The chemotherapy group exhibited significantly lower 5-year recurrence and distant failure rates compared to the radiotherapy group (p<0.001 and p = 0.007, respectively. Nausea and vomiting were the most frequent short-term complications of chemotherapy, whereas bowel and urinary complications were more frequent in the radiotherapy group. Compared to the chemotherapy group, patients who received radiotherapy reported a lower QoL, less frequent sexual activity, and more severe menopausal symptoms (p<0.05. Cervical cancer patients treated with chemotherapy, especially those with early-stage disease, clinical responses, and younger ages, have more positive outcomes, fewer complications, better QoL and sexual activity, suggesting that chemotherapy may be a valuable alternative option for selected patients.

  16. Adjuvant chemotherapy for the treatment of PNET/medulloblastoma in children

    The major problems currently associated with management of PNET/medulloblastoma are a high mortality rate and late morbidity of craniospinal radiotherapy. Thirty-six children with either PNET (12 patients) or medulloblastoma (24 patients) were assessed to try and define the role of adjuvant chemotherapy. Prior to 1991, 23 children mainly were treated by surgery or craniospinal radiation therapy. Two-year and 5-year overall survival rates accounted for 52% and 39%, respectively, of the cases. A mean postoperative observation period of 161 months showed seven children to be alive, but six of them suffered serious mental retardation and endocrinological deficits. Since 1991, 13 newly-diagnosed children have been treated with cisplatin-based intensive chemotherapy every four weeks for 8 cycles. Four children under two years of age at first were treated with 8 cycles of chemotherapy, and then irradiated. Complete remissions were achieved in 11 of the 13 patients. The two-year survival rate was 82% and the disease-free survival rate 62% (8/13) with a mean observation period of 29 postoperative months. In conclusion, cisplatin-based chemotherapy appears to be effective adjuvant therapy for management of children with PNET/medulloblastoma. (author)

  17. C-erbB-2 expression and benefit from adjuvant chemotherapy and radiotherapy of breast cancer

    Staal, O.; Sullivan, S.; Wingren, S.; Skoog, L.; Rutqvist, L.E.; Nordenskjoeld, B. [Karolinska Sjukhuset, Stockholm (Sweden); Carstensen, J.M. [Linkoeping Univ. (Sweden)

    1995-12-31

    Frozen tissue from primary tumours of 152 premenopausal breast cancer patients, who participated in a trial comparing radiotherapy with adjuvant chemotherapy (cyclophosphamide, methotrexate, 5-fluorouracil, CMF), was analysed for c-erbB-2 protein expression, measured by flow cytometry. The relative risk of distant recurrence or death in the chemotherapy group as compared with the radiotherapy group was 3.0 (95% confidence interval (CI) 1.1-7.8) for patients whose tumours showed high c-erbB-2 levels and 0.87 (95% CI 0.43-1.7) for those with tumours with low levels of c-erbB-2 protein. Patients with highly proliferative tumours that did not overexpress c-erbB-2 benefited most, in terms of survival, from CMF. In addition, we found an increased risk of locoregional recurrence for tumours overexpressing c-erbB-2 when radiotherapy was replaced by chemotherapy. (author).

  18. Adjuvant breast cancer chemotherapy during late-trimester pregnancy: not quite a standard of care

    Epstein Richard J

    2007-05-01

    Full Text Available Abstract Background Diagnosis of breast cancer during pregnancy was formerly considered an indication for abortion. The pendulum has since swung to the other extreme, with most reviews now rejecting termination while endorsing immediate anthracycline-based therapy for any pregnant patient beyond the first trimester. To assess the evidence for this radical change in thinking, a review of relevant studies in the fields of breast cancer chemotherapy, pregnancy, and drug safety was conducted. Discussion Accumulating evidence for the short-term safety of anthracycline-based chemotherapy during late-trimester pregnancy represents a clear advance over the traditional norm of therapeutic abortion. Nonetheless, the emerging orthodoxy favoring routine chemotherapy during gestation should continue to be questioned on several grounds: (1 the assumed difference in maternal survival accruing from chemotherapy administered earlier – i.e., during pregnancy, rather than after delivery – has not been quantified; (2 the added survival benefit of adjuvant cytotoxic therapy prescribed within the hormone-rich milieu of pregnancy remains presumptive, particularly for ER-positive disease; (3 the maternal survival benefit associated with modified adjuvant regimens (e.g., weekly schedules, omission of taxanes, etc. has not been proven equivalent to standard (e.g., post-delivery regimens; and (4 the long-term transplacental and transgenerational hazards of late-trimester chemotherapy are unknown. Summary Although an incrementally increased risk of cancer-specific mortality is impossible to exclude, mothers who place a high priority on the lifelong well-being of their progeny may be informed that deferring optimal chemotherapy until after delivery is still an option to consider, especially in ER-positive, node-negative and/or last-trimester disease.

  19. Adjuvant chemotherapy is not associated with improved survival for all high-risk factors in stage II colon cancer.

    Adjuvant chemotherapy can be considered in high-risk stage II colon cancer comprising pT4, poor/undifferentiated grade, vascular invasion, emergency surgery and/or colon cancer who underwent resection and were diagnosed in the Netherlands between 2008 and 2012 were included. After stratification by risk factor(s) (vascular invasion could not be included), Cox regression was used to discriminate the independent association of adjuvant chemotherapy with the probability of death. Relative survival was used to estimate disease-specific survival. A total of 4,940 of 10,935 patients with stage II colon cancer were identified as high risk, of whom 790 (16%) patients received adjuvant chemotherapy. Patients with a pT4 received adjuvant chemotherapy more often (37%). Probability of death in pT4 patients receiving chemotherapy was lower compared to non-recipients (3-year overall survival 91% vs. 73%, HR 0.43, 95% CI 0.28-0.66). The relative excess risk (RER) of dying was also lower for pT4 patients receiving chemotherapy compared to non-recipients (3-year relative survival 94% vs. 85%, RER 0.36, 95% CI 0.17-0.74). For patients with only poor/undifferentiated grade, emergency surgery or colon cancer, adjuvant chemotherapy was associated with higher survival in pT4 only. To prevent unnecessary chemotherapy-induced toxicity, further refinement of patient subgroups within stage II colon cancer who could benefit from adjuvant chemotherapy seems indicated. PMID:26914273

    Purpose US veterans have been shown to be a vulnerable population with high cancer rates, and cancer care quality in Veterans Affairs (VA) hospitals is the focus of a congressionally mandated review. We examined rates of surgery and chemotherapy use among veterans with colon cancer at VA and non-VA facilities in California to gain insight into factors associated with quality of cancer care. Methods A retrospective cohort of incident colon cancer patients from the California Cancer Registry, who were ≥ 66 years old and eligible to use VA and Medicare between 1999 and 2001, were observed for 6 months after diagnosis. Results Among 601 veterans with colon cancer, 72% were initially diagnosed and treated in non-VA facilities. Among veterans with stage I to III cancer, those diagnosed and initially treated in VA facilities experienced similar colectomy rates as those at non-VA facilities. Stage III patients diagnosed and initially treated in VA versus non-VA facilities had similar odds of receiving adjuvant chemotherapy. In both settings, older patients had lower odds of receiving chemotherapy than their younger counterparts even when race and comorbidity were considered (age 76 to 85 years: odds ratio [OR] = 0.18; 95% CI, 0.07 to 0.46; age ≥ 86 years: OR = 0.17; 95% CI, 0.04 to 0.73). Conclusion In California, older veterans with colon cancer used both VA and non-VA facilities for cancer treatment, and odds of receiving cancer-directed surgery and chemotherapy were similar in both systems. Among stage III patients, older age lowered odds of receiving adjuvant chemotherapy in both systems. Further studies should continue to explore potential health system effects on quality of colon cancer care across the United States. PMID:20406940

  1. Adjuvant chemotherapy prior to postoperative concurrent chemoradiotherapy for locoregionally advanced head and neck cancer

    Background and purpose: Induction chemotherapy prior to definitive concurrent chemoradiotherapy (CCRT) is a promising treatment option for unresectable head and neck cancer (HNC). In the postoperative setting, the efficacy of such an approach with adjuvant chemotherapy (AdjCT) followed by postoperative CCRT is unclear. Materials and methods: Forty-one postoperative patients with stage III-IV (M0) HNC enrolled on 3 consecutive phase II clinical trials were retrospectively analyzed. Twenty-five of the patients were treated on a protocol which included AdjCT with carboplatin and paclitaxel prior to postoperative CCRT (AdjCT group). Sixteen were treated on protocols with similar postoperative CCRT but without AdjCT (control group). CCRT consisted of paclitaxel, 5-fluorouracil, hydroxyurea, and twice-daily radiotherapy. Results: After a median follow-up of 72 months, there were no locoregional failures (LRF) or distant metastases (DM) in the AdjCT group. In the control group, there were 2 LRF and 2 DM. The 5-year risk of disease recurrence was 0% in the AdjCT group, compared to 28.9% in the control group (p = 0.0074). No patients had disease progression during AdjCT, and all proceeded to postoperative CCRT without delay. Conclusions: Adjuvant chemotherapy after surgery followed by CCRT may be a treatment strategy associated with favorable disease outcomes in locoregionally advanced HNC. These results pose a hypothesis which warrants further investigation.

    2011-01-01

    Neoadjuvant chemotherapy (NAC) has drawn more attention to the treatment of locally advanced gastric cancer (AGC) in the current multidisciplinary treatment model. EORTC trial 40954 has recently reported that NAC plus surgery without postoperative adjuvant chemotherapy could not benefit the locally AGC patients in their overall survival. We performed a meta-analysis of 10 studies including 1518 gastric cancer patients. Stratified subgroups were NAC plus surgery and NAC plus both surgery and adjuvant chemotherapy (AC), while control was surgery alone. The results showed that NAC plus surgery did not benefit the patients with locally AGC in their overall survival [odds ratio (OR) = 1.20, 95% CI 0.80-1.80, P = 0.37] and the number needed to treat (NNT) was 74. However, the NAC plus both surgery and AC had a slight overall survival benefit (OR = 1.33, 95% CI 1.03-1.71, P = 0.03) and NNT was 14, which is superior to the NAC plus surgery. Therefore, we recommend that combined NAC and AC should be used to improve the overall survival of the locally AGC patients.

  3. Clinical outcome of adjuvant chemotherapy plus intensity modulated radiotherapy after breast-conserving surgery

    Objective: To evaluate the efficacy and side effects of adjuvant chemotherapy plus intensity modulated radiotherapy (IMRT) after breast-conserving surgery for stage I and II breast cancer. Methods: After breast-conserving surgery, 108 patients received six cycles of chemotherapy followed by IMRT. The irradiation dose of the whole breast was 50 Gy given by 25 fractions, followed by 10 Gy boost to the tumor bed given by 5 fractions with electron beams. Patients with positive estrone receptor or progesterone receptor were given endocrine treatment, mostly with tamoxifen. Results: The follow-up rate was 100% by December 2007. The number of patients followed-up at 1-, 2- and 3-year was 108,88 and 58. The 1-, 2- and 3-year over survival rates were 100%, 100% and 98%. Three patients had local recurrence. Different degree of dermatitis occurred with good long-term cosmetic results. No severe side effects occurred such as radiation-induced pneumonitis, pulmonary, fibrosis and heart injury. Conclusions: Breast cancer patients treated by adjuvant chemotherapy plus IMRT after breast-conserving surgery have high survival rate and low side-effect rate. The survival quality and local control can be improved. (authors)

  4. Neoadjuvant or adjuvant chemotherapy: what is the best treatment of muscle invasive bladder cancer?

    Nabil Ismaili

    2011-09-01

    Full Text Available Bladder cancer is the fourth most common cancer for men and the eighth most common cancer for women. Transitional cell carcinoma is the most predominant histological type. Bladder cancer is highly chemosensitive. In metastatic setting the treatment is based on cisplatin chemotherapy regimens type MVAC, MVAC-HD or gemcitabine plus cisplatin. The standard treatment of muscle invasive operable bladder cancer (T2–T4 used widely was radical cystectomy with pelvic lymph nodes dissection; the anatomical extent of pelvic lymphadenectomy has not accurately been defined so far. However, in the last decade, the treatment of tumors was improved by the introduction of chemotherapy as part of the management of the disease. Neoadjuvant chemotherapy should be considered at first, as standard treatment of choice, before local treatment for patients with good performance status (0–1 and good renal function–glomerular filtration rate (GFR >60 mL/min. For patients treated with primary surgery, adjuvant chemotherapy is a valuable option in the case of lymph nodes involvement. This brief review would provide the evidence of the role of neoadjuvant chemotherapy in the management of operable muscle invasive (T2–T4 bladder cancer.

Previous research has indicated that patient refusal of treatment is a contributing factor. This study aimed to identify potential barriers to adjuvant chemotherapy use in older patients by examining the associations between patient age, factors influencing chemotherapy treatment decisions, and preferences for information and decision-making involvement.Patients and methods: Sixty-eight patients who underwent surgery for colorectal cancer in Sydney, Australia, within the previous 24 months completed a self-administered survey.Results: Fear of dying, health status, age, quality of life, and understanding treatment procedures and effects were significantly more important to older patients (aged ≥65 years than younger patients in deciding whether to accept chemotherapy (all P < 0.05. Reducing the risk of cancer returning and physician trust were important factors for all patients. Practical barriers such as traveling for treatment and cost were rated lowest. Older patients preferred less information and involvement in treatment decision making than younger patients. However, 60% of the older group wanted detailed information about chemotherapy, and 83% wanted some involvement in decision making. Those preferring less information and involvement still rated many factors as important in their decision making, including understanding treatment procedures and effects.Conclusion: A range of factors appears to influence

  6. Should all patients with serous and clear cell endometrial carcinoma receive adjuvant chemotherapy?

    Boren, Todd P; Miller, David S

    2010-11-01

    Uterine papillary serous carcinoma (UPSC) and uterine clear cell carcinoma (UCCC) represent two rare subtypes that have an increased risk of recurrence and worse overall survival compared with the more common endometrioid endometrial cancers. Meaningful data in the form of prospective randomized trials is lacking for both advanced and early-stage UPSC and UCCC. Data extrapolated from prospective trials in advanced endometrioid endometrial cancer and retrospective trials on early-stage UPSC suggest that adjuvant platinum and taxane-based chemotherapy may provide a survival benefit for these patients. Future trials specifically examining UPSC and UCCC are needed to elucidate the optimal treatment regimen for these patients. Given the current data, the option of chemotherapy should be considered in treatment-planning discussions for all patients with UPSC and UCCC. PMID:21118038

  7. Medullobalstoma - treatment results after postoperative radiation therapy with and without adjuvant chemotherapy

    Between 1975 and 1991, 40 patients with newly diagnosed medulloblastoma were treated at the authors' institutions. After aggressive surgical resection 39/40 (98%) received craniospinal radiation therapy with a local boost to the posterior fossa and other macroscopically involved areas. A group of 29 patients was treated with adjuvant chemotherapy. The five-year actuarial survival and event-free survival were 75% and 65%, respectively. Survival was significantly better for patients treated after 1981 as compared to those treated between 1975 and 1980 (p=.02). Younger age (two to four years) was associated with a better prognosis (p=.02). The extend of resection, Chang-stage, radiation dose to posterior fossa and the use of chemotherapy did not significantly impact on survival and relapse-free survival. (orig.)

  8. In Vitro Adenosine Triphosphate-Based Chemotherapy Response Assay as a Predictor of Clinical Response to Fluorouracil-Based Adjuvant Chemotherapy in Stage II Colorectal Cancer

    Kwon, Hye Youn; Kim, Im-kyung; Kang, Jeonghyun; Sohn, Seung-Kook; Lee, Kang Young

    2016-01-01

    Purpose We evaluated the usefulness of the in vitro adenosine triphosphate-based chemotherapy response assay (ATP-CRA) for prediction of clinical response to fluorouracil-based adjuvant chemotherapy in stage II colorectal cancer. Materials and Methods Tumor specimens of 86 patients with pathologically confirmed stage II colorectal adenocarcinoma were tested for chemosensitivity to fluorouracil. Chemosensitivity was determined by cell death rate (CDR) of drug-exposed cells, calculated by comparing the intracellular ATP level with that of untreated controls. Results Among the 86 enrolled patients who underwent radical surgery followed by fluorouracil-based adjuvant chemotherapy, recurrence was found in 11 patients (12.7%). The CDR ≥ 20% group was associated with better disease-free survival than the CDR < 20% group (89.4% vs. 70.1%, p=0.027). Multivariate analysis showed that CDR < 20% and T4 stage were poor prognostic factors for disease-free survival after fluorouracil-based adjuvant chemotherapy. Conclusion In stage II colorectal cancer, the in vitro ATP-CRA may be useful in identifying patients likely to benefit from fluorouracil-based adjuvant chemotherapy. PMID:26511802

  9. Comparison between ultrasonography and [18F]FDG PET for pathological response of breast cancer to neo-adjuvant chemotherapy

    To compare between ultrasonography (US) and the predictive value of [18F]fluorodeoxyglucose positron emission tomography (FDG PET) for the pathological response of breast cancer after completion of neo-adjuvant chemotherapy. Twenty eight patients with newly diagnosed, locally advanced breast cancer were evaluated with US and PET before and after neo-adjuvant chemotherapy. Chemotherapy response with US was classified by UICC. Reduction rate of pSUV with PET was measured for residual disease assessment. Pathological responses were classified into three groups: pathological non-response (pNR), pathological partial response (pPR), and pathological complete response (pCR). PET correctly predicted pathologic responses in 22 of 28 patients (78.6%); US correctly predicted in 21 of 28 patients (75%). Significant differences between chemotherapy responses of US and residual tumor assessments of PET to neo-adjuvant chemotherapy were not observed (>0.05). Two patients with pPR who were predicted with US to have complete response were classified as partial response in PET. Also, a patient with pNR was predicted with US to have partial response in US, but partial response in PET. In this study, differences between US and PET were not statistically significant. But PET provides additional information that cannot be assessed in US for the pathological response of breast cancer after completion of neo-adjuvant chemotherapy

    The authors treated 10 advanced renal cell carcinoma with circadian venous continuous infusion of 5-Fluoro 2-Deoxyuridine (FUDR). The drug was delivered by Medtronic Synchromed implantable pump in 14-day cycles alternating with 14-day intervals of physiologic saline infusion. Of the patient observed for at least 8 months (range: 8-32, median: 22.1) 1 showed progression. Circadian continuous central venous infusion of FUDR is minimally toxic. The FUDR can be delivered safely and conveniently in this way for long spans. This therapy is administrated in on entirely out patient setting, and associated with a normal quality of life.

    Full Text Available To evaluate factors affecting the use and delay ≥8 weeks of adjuvant chemotherapy and the impact of chemotherapy use and delay on survival.Between 2005 and 2012, consecutive patients with stage II and III colorectal cancer who were treated with major curative resection were enrolled.Among 750 patients with stage II (n = 318 and III (n = 432 disease, 153 (20.4% did not receive chemotherapy. Among 597 patients with adjuvant chemotherapy, 31 (5.2% began chemotherapy 8 weeks or more after surgery. Factors associated with not receiving chemotherapy were: age ≥80 years (hazard ratio [HR] = 5.2, American Society of Anesthesiologists score ≥3 (HR = 1.9, underlying cerebrovascular disease (HR = 1.7, stage II disease (HR = 2.0, presence of postoperative complications (HR = 2.2, or intensive care unit admission (HR = 2.4. Factors associated with chemotherapy delay ≥8 weeks were: male sex (HR = 4.2, rectal primary cancer (HR = 5.4, or presence of postoperative complications (HR = 2.5. Independent prognostic factors for overall survival included TNM III stage (HR = 2.04 and chemotherapy delay ≥8 weeks (HR = 0.39 or <8 weeks (HR = 0.22. Independent prognostic factors for recurrence-free survival were TNM III stage (HR = 2.26 and chemotherapy delay <8 weeks (HR = 0.35.Postoperative complications were associated with both lack of and delayed chemotherapy. Timely initiation of chemotherapy, defined as <8 weeks, was a favorable prognostic factor for overall and recurrence-free survival. To increase the proportion of patients receiving chemotherapy and timely initiation of chemotherapy, surgical complications should be minimized after curative resection.

    With the aging of the Chinese population, it seems obvious that the number of elderly patients with the disease of colorectal carcinoma grows significantly. Meanwhile, no evidence-based practical guideline for the treatment of colorectal carcinoma are available in this particular age group. Therefore, the concept of integrative management has been brought up by the Colorectal Cancer Center of the Second Affiliated Hospital of Zhejiang University, which combines the processes of surgery, perioperative rehabilitation and adjuvant chemotherapy together. In this way, the cooperation and complementarity between different clinical departments could cooperate and complete tasks together to integrate the treatment processes into a cohesive one. To achieve the goal of integrative management, the project is divided into horizontal and vertical aspects. The horizontal integration means the cooperation between different clinical departments, which is also known as multi-discipline treatment (MDT). The vertical integration reflects the completeness of the entire treatment under the goal of consistency, strictness and job separation, which could also be explained as the clinical pathway. Furthermore, this review stresses on the integrative strategy of both clinical and biochemical indexes rehabilitation, as well as the operation and postoperative adjuvant chemotherapy which has been put in execution several years by the Colorectal Cancer Center of the Second Affiliated Hospital of Zhejiang University.

    BACKGROUND: Hepatocellular carcinoma (HCC) is one of the most common tumors worldwide and liver transplanta-tion (LT) is considered as the best therapeutic option for patients with HCC combined with cirrhosis. However, tumor recurrence after LT for HCC remains the major obstacle for long-term survival. The present study was to evaluate the efif-cacy and necessity of adjuvant chemotherapy in patients with HCC who had undergone LT. DATA SOURCES: Several databases were searched to identify comparative studies fuliflling the predeifned selection criteria before October 2014. Suitable studies were chosen and data extracted for meta-analysis. Three authors independently evaluated the bias of each study according to the Cochrane Handbook for Systematic Review of Intervention. Stata 12 was used for statistical analysis. Hazard ratio (HR) was considered as a summary statistic for overall survival, disease-free survival and recurrence rate. RESULTS: Three prospective studies and 5 retrospective stud-ies including 360 patients (166 in the adjuvant chemotherapy group, and 194 in the control group) were included. Com-pared with the control group, post-LT adjuvant chemotherapy conferred signiifcant beneift for overall survival (HR: 0.34;95% CI: 0.22-0.52;P=0.000). Meanwhile, the results showed an improvement for disease-free survival on favoring adju-vant chemotherapy (HR: 0.87; 95% CI: 0.78-0.95;P=0.004). However, no signiifcant difference in HCC recurrence rate was observed between the two groups (HR: 1.26; 95% CI: 0.40-4.00;P=0.696). Descriptions of adverse events were of anecdotal na-ture and did not allow meta-analytic calculations. CONCLUSIONS: Adjuvant chemotherapy after LT for HCC can signiifcantly prolong patient's survival and delay the recurrence of HCC. For advanced HCC with poor differentia-tion, patients may perhaps beneift from the early implantation of adjuvant chemotherapy after LT.

  15. Short-course radiotherapy followed by neo-adjuvant chemotherapy in locally advanced rectal cancer – the RAPIDO trial

    Current standard for most of the locally advanced rectal cancers is preoperative chemoradiotherapy, and, variably per institution, postoperative adjuvant chemotherapy. Short-course preoperative radiation with delayed surgery has been shown to induce tumour down-staging in both randomized and observational studies. The concept of neo-adjuvant chemotherapy has been proven successful in gastric cancer, hepatic metastases from colorectal cancer and is currently tested in primary colon cancer. Patients with rectal cancer with high risk features for local or systemic failure on magnetic resonance imaging are randomized to either a standard arm or an experimental arm. The standard arm consists of chemoradiation (1.8 Gy x 25 or 2 Gy x 25 with capecitabine) preoperatively, followed by selective postoperative adjuvant chemotherapy. Postoperative chemotherapy is optional and may be omitted by participating institutions. The experimental arm includes short-course radiotherapy (5 Gy x 5) followed by full-dose chemotherapy (capecitabine and oxaliplatin) in 6 cycles before surgery. In the experimental arm, no postoperative chemotherapy is prescribed. Surgery is performed according to TME principles in both study arms. The hypothesis is that short-course radiotherapy with neo-adjuvant chemotherapy increases disease-free and overall survival without compromising local control. Primary end-point is disease-free survival at 3 years. Secondary endpoints include overall survival, local control, toxicity profile, and treatment completion rate, rate of pathological complete response and microscopically radical resection, and quality of life. Following the advances in rectal cancer management, increased focus on survival rather than only on local control is now justified. In an experimental arm, short-course radiotherapy is combined with full-dose chemotherapy preoperatively, an alternative that offers advantages compared to concomitant chemoradiotherapy with or without postoperative

    Objective: To investigate the effect of adjuvant chemotherapy on early stage cervical cancer with bulky tumor. Methods: Between Mar 1998 and Aug 2002, 162 patients of cervical cancer with Ib~IIa stage were investigated. 21 patients with bulky tumors (≥4cm) were managed by cisplatin-based chemotherapy followed by radical hysterectomy and pelvic lymphadenectomy (Bulky-chemo group, BC group). The change of tumor size, the depth of stromal invasion, lymph node metastasis and the involvement of surgical specimens were assessed after operation and compared with those in 57 patients with bulky tumors (Bulky-nonchemo group, BN group) and 84 patients with the tumor size less than 4cm (small group, S group) who underwent surgery as the first step of treatment. Chemotherapy with the same regimen was offered for another 1~2 cycles after operation and the survival situation was followed up. Results: The tumor size of 21 patients in BC group were decreased to varying degrees after chemotherapy, 15 patients were shown as clinical effectiveness (71.43%). And the blood loss during operation (352.35(19.01ml) was significantly lower than that in BN group (619.05(35.58ml), t=4.37) and that in S group (568.07(45.23ml, t=3.36) patients. The incidence of lymph node metastasis (9/78) in patients with bulky tumors was greatly higher than those with tumor size less than 4cm (3/84, X2=4.416); its prevalence rate of deep wall infiltration (8/78) was also higher than that of the latter group (2/84), while with no statistical significance (X2=3.089). Histology showed that there was no case of marginal involvement in all patients. The ratio of both deep stromal invasion (1/21) and positive lymph node (2/21) in BC group was lower than that in BN group (7/57, 7/57 respectively), but neither with statistical significance (X2=0.0103 and 0.8193 respectively). Conclusion: Pre-operative chemotherapy can improve decreasing the primary tumor size and facilitate the following radical surgery. While

    Full Text Available Biomarkers may be useful when deciding which nonsmall cell lung cancer (NSCLC patients may benefit from adjuvant chemotherapy following complete resection and which chemotherapeutic agents may be used preferably in individual patients in order to maximise survival. A literature search covering the period from 2003 to May, 2014 was conducted using PubMed and the following search terms: “non-small cell lung cancer”, “NSCLC”, “adjuvant chemotherapy”, “randomized”, “randomised”, “biomarkers”, “prognostic”, “predictive”. This review focuses on current knowledge of biomarkers for prognosis or efficacy of adjuvant treatment following complete resection in stage I–IIIA NSCLC patients. This review includes results on 18 different biomarkers and five gene profiles. A statistically significant prognostic impact was reported for: iNTR, TUBB3, RRM1, ERCC1, BRCA1, p53, MRP2, MSH2, TS, mucin, BAG-1, pERK1/2, pAkt-1, microRNA, TopIIA, 15-gene profile, 92-gene profile, 31-gene profile and 14-gene profile. A statistically significant predictive impact was reported for: ERCC1, p53, MSH2, p27, TUBB3, PARP1, ATM, 37-gene profile, 31-gene profile, 15-gene profile and 92-gene profile. Uncertainties regarding the optimal analysis method and cut-off levels for the individual markers may blur the prognostic or predictive signals. None of the possible predictive markers have been validated in prospective trials. Thus, there are no biomarkers ready to use in an adjuvant setting in NSCLC.

    Objective To investigate the potential role of preoperative adjuvant chemotherapy on early stage cervical squamouscarcinoma with bulky tumor.Methods One hundred and forty-five patients with cervical squamous cancer stages Ⅰb-Ⅱa were investigated, among which 17 patients with bulky tumors (≥4 cm) were managed by cisplatin-based chemotherapy for 1-2 courses followed by radical hysterectomy and pelvic lymphadenectomy (BC group). The change of tumor size, pelvic lymph nodes metastasis, cervical wall invasion, the involvement of surgical specimen margin, and the blood loss during operation were assessed after operation and compared with those in 51 patients with bulky tumors (BN group) and 77 patients with small local tumors (S group)who underwent surgery directly.Results (1) The tumor size of 17 patients in BC group were decreased in various degrees after chemotherapy, with 13 patients of clinical effectiveness (76.47%). And the responsiveness pertained to neither histological differentiation nor size of local tumors. (2) Post-operative histology has showed that patients in BC and BN group have higher incidence of lymph node metastasis and deep cervical infiltration (5/68 and 3/68, respectively) than in S group (1/77 and 1/77, respectively) while with no statistical significance. (3) Blood loss during operation in BC group was less than BN and S group. (4) Seventeen patients, including those underwent surgeries of vaginal prolongation and/or ovarian transposition, appeared disease-free survival within the follow-up time.Conclusions Most of patients with bulky early stage cervical squamous carcinoma are sensitive to cisplatin-based chemotherapy, which could greatly reduce local tumor size and in turn facilitate the following operation by well controlling blood loss.

  20. EMX2 Is a Predictive Marker for Adjuvant Chemotherapy in Lung Squamous Cell Carcinomas.

    Dongsheng Yue

    Full Text Available Squamous cell carcinomas (SCC account for approximately 30% of non-small cell lung cancer (NSCLC. Current staging methods do not adequately predict outcome for this disease. EMX2 is a homeo-domain containing transcription factor known to regulate a key developmental pathway. This study assessed the significance of EMX2 as a prognostic and predictive marker for resectable lung SCC.Two independent cohorts of patients with lung SCC undergoing surgical resection were studied. EMX2 protein expression was examined by immunohistochemistry, Western blot, or immunofluorescence. EMX2 expression levels in tissue specimens were scored and correlated with patient outcomes. Chemo-sensitivity of lung SCC cell lines stably transfected with EMX2 shRNAs to cisplatin, carboplatin, and docetaxel was examined in vitro.EMX2 expression was down-regulated in lung SCC tissue samples compared to their matched adjacent normal tissues. Positive EMX2 expression was significantly associated with improved overall survival in stage I lung SCC patients, and in stage II/IIIA lung SCC patients receiving adjuvant chemotherapy. EMX2 expression was also associated with expression of EMT markers in both lung SCC cell lines and tissue samples. Knock-down of EMX2 expression in lung SCC cells promoted chemo-resistance and cell migration.EMX2 expression is down-regulated in lung SCC and its down-regulation is associated with chemo-resistance in lung SCC cells, possibly through regulation of Epithelial-to-Mesenchymal Transition (EMT. EMX2 may serve as a novel prognostic marker for stage I lung SCC patients and a prediction marker for stage II/IIIA lung SCC patients receiving adjuvant chemotherapy.

    AIM: To compare the efficacy and toxicity of a three-step combination therapy with post-operative radiation alone for locally advanced esophageal cancer.METHODS: Patients with T3-4 and N0-1 esophageal carcinoma from a number of institutions were non-randomly,prospectively enrolled in the study. All patients underwent single-stage curative en bloc esophagectomy. The patients were then assigned into one of two treatment groups based on treatment consisting of either post-operative concurrent chemoradiotherapy (CCRT) with weekly cisplatin 30 mg/m2 followed by systemic adjuvant chemotherapy (four monthly cycles of cisplatin 20 mg/m2 and 5-fiuorouracil 1 000 mg/m2 for five consecutive days),or, post-operative radiation alone. The radiotherapy dose was 55-60 Gy for all patients. Primary end-point of this study was to assess the per-protocol patients' improvement of overall survival benefit. Secondary end-point was designed to evaluate both the per-protocol and intent-to-treat patients' outcome of survival.RESULTS: A total of 60 patients (n = 30 per group) were enrolled in this study. The two groups were generally comparable for demographic characteristics and hematological and non-hematological toxicities. The CCRT with weekly cisplatin was well tolerated, with significantly better overall survival (30.9 mo vs 20.7 mo; 95% CI,27.5-36.4 vs15.2-26.1) and 3-year survival (70.0% vs 33.7%; P = 0.003). Low histological grade of tumor (P<0.001) was associated with favorable survival in these locally advanced patients.CONCLUSION: For locally advanced esophageal cancer,the combination of esophagectomy, post-operative CCRT with weekly cisplatin and systemic adjuvant chemotherapy is well tolerated and effective. A large-scale, prospective randomized trial of this regimen is in progress.

  3. Metronomic Adjuvant Chemotherapy Improves Treatment Outcome in Nasopharyngeal Carcinoma Patients With Postradiation Persistently Detectable Plasma Epstein-Barr Virus Deoxyribonucleic Acid

    Purpose: To investigate the effects of adjuvant chemotherapy in nasopharyngeal carcinoma (NPC) patients with persistently detectable plasma Epstein-Barr virus DNA (pEBV DNA) after curative radiation therapy plus induction/concurrent chemotherapy. Methods and Materials: The study population consisted of 625 NPC patients with available pEBV DNA levels before and after treatment. Eighty-five patients with persistently detectable pEBV DNA after 1 week of completing radiation therapy were eligible for this retrospective study. Of the 85 patients, 33 were administered adjuvant chemotherapy consisting of oral tegafur-uracil (2 capsules twice daily) for 12 months with (n=4) or without (n=29) preceding intravenous chemotherapy of mitomycin-C, epirubicin, and cisplatin. The remaining 52 patients who did not receive adjuvant chemotherapy served as the control group. Results: Baseline patient characteristics at diagnosis (age, sex, pathologic type, performance status, T classification, N classification, and overall stage), as well as previous treatment modality, were comparable in both arms. After a median follow-up of 70 months for surviving patients, 45.5% (15 of 33 patients) with adjuvant chemotherapy and 71.2% (37 of 52 patients) without adjuvant chemotherapy experienced tumor relapses (P=.0323). There were a significant reduction in distant failure (P=.0034) but not in local or regional recurrence. The 5-year overall survival rate was 71.6% for patients with adjuvant chemotherapy and 28.7% for patients without adjuvant chemotherapy (hazard ratio 0.27; 95% confidence interval 0.17-0.55; P<.0001). Conclusions: Our retrospective data showed that adjuvant chemotherapy can reduce distant failure and improve overall survival in NPC patients with persistently detectable pEBV DNA after curative radiation therapy plus induction/concurrent chemotherapy

  5. Clinical application of FDG PET for pathological response of breast cancer after neo-adjuvant chemotherapy

    The purpose of this study was to assess the clinical usefulness of FDG PET in predicting the pathological response in breast cancer after neoadjuvant chemotherapy. 33 patients with newly diagnosed, locally advanced breast cancer had PET scans before and after chemotherapy to assess tumor response, and then pathology was confirmed after surgery. FDG PET for assessing tumor response was done by measuring peak SUV (pSUV) and then calculating reduction rate (RR). RR was stratified into RR complete response (rrCR) at >88% reduction, RR partial response (rrPR) at RR between 56∼87%, and no response (rrNR) in reductions <55%. Clinical assessment was done with physical exams, U/S, and CT. Histopathological response were classified into pathological no response(pNR), pathological partial response (pPR) and pathological complete response (pCR). 15% (5 of 33) patients had pCR, 85% (28 of 33) had pPR. Using a 88% reduction in SUV as a threshold value for differentiation between pCR from pPR, PET scans correctly differentiated pCR in 3 patients out of 5. When using a cut off value of 55% reduction rate, PET scans correctly differentiated pPR in 19 patients out of 21, and for pNR, the PET scans correctly differentiated only 2 patients out of 7. Diagnostic accuracy of PET for pathologic response was 25 out of 33 cases (75.8%). The diagnostic accuracy of clinical assessment was 25 of 33 cases (72.7%). This study suggests that pSUV reduction rate can be a useful tool when predicting the pathological response of primary breast cancers after neo-adjuvant chemotherapy

  6. Biological characterization and selection criteria of adjuvant chemotherapy for early breast cancer: experience from the Italian observational NEMESI study

    International treatment guidelines recommend administration of adjuvant chemotherapy in early breast cancer based on clinical, prognostic and predictive parameters. An observational study (NEMESI) was conducted in 63 Italian oncology centres in patients with early breast cancer. Age, performance status, concomitant disease, menopausal status, histology, tumor dimension (pT), axillary lymph node status (pN), grading (G), estrogen and progesterone receptor (ER and PgR), proliferative index (ki67 or MIB-1), human epidermal growth factor receptor 2 (HER2) and type of adjuvant treatment were recorded. The primary objective of the study was to define parameters influencing the decision to prescribe adjuvant chemotherapy and the type of chemotherapy. Data for 1894 patients were available. 69.0% postmenopausal, 67.0% pT1, 22.3% pTmic/pT1a/pT1b, 61.0% pN0, 48.7% luminal A, 18.1% luminal B, 16.1% HER2 positive, 8.7% triple negative, 8.4% unknown. 57.8% received adjuvant chemotherapy: 38.1% of luminal A, 67.3% luminal B, 88.2% HER2-positive, 97.6% triple negative. Regimens administered: 9.1% CMF-like, 48.8% anthracyclines, 38.4% anthracyclines plus taxanes, 3.7% taxanes alone. Increasing pT/pN and, marginally, HER2-positive were associated with the prescription of anthracyclines plus taxanes. Suboptimal schedules (CMF-like or AC/EC or FEC-75) were prescribed in 37.3% receiving chemotherapy, even in HER2-positive and triple negative disease (36.5% and 34.0%, respectively). This study showed an overprescription of adjuvant chemotherapy for early breast cancer, particularly referred to luminal A. pT, pN and, marginally, HER2 were the principal determinants for the choice of chemotherapy type. Suboptimal chemotherapy regimens were adopted in at least one third of HER2-positve and triple negative

    Nasopharyngeal carcinoma (NPC) patients with N2-3 diseases are prone to develop distant metastasis even treated with standard concurrent chemoradiotherapy (CCRT). Our study is aim to determine the optimal treatment strategy of these patients. Patients with histologically proven NPC were retrospectively analyzed according to the AJCC 2002 stage classification system. A total of 547 patients who had N2-3 diseases were enrolled. They were all treated with Intensity-modulated radiation therapy (IMRT) combined with systemic treatments, including radiotherapy alone (RT alone), neoadjuvant chemotherapy followed by radiotherapy (NACT+RT), CCRT, NACT+CCRT, NACT followed by radiotherapy and adjuvant chemotherapy (NACT+RT+AC), CCRT+AC and NACT+CCRT+AC. A subgroup analysis was also conducted. With a median follow-up time of 53.8 months, adjuvant chemotherapy significantly decreased the risk of distant metastasis (HR 0.413, 95% CI 0.194-0.881, p = 0.022) as well as significantly increased the OS (HR 0.398, 95% CI 0.187-0.848, p = 0.017) in patients with N3 disease. The addition of adjuvant chemotherapy seemed to provide benefits to patients with N3 stage NPC and the current study may indicate the need for further randomized investigation. PMID:26942700

  8. Sequence of Radiation Therapy and Chemotherapy as Adjuvant Treatment in Breast Cancer

    The aim of the work was to evaluate the prognostic importance of the sequence of radiotherapy (RT) and chemotherapy (CT) as adjuvant treatment in women with breast cancer who were treated with modified radical mastectomy or total mastectomy and their correlation also with other known prognostic factors. Methods: In this retrospective study, 200 women with breast cancer were evaluated. The age ranged from 25 to 73 years, with the mean age of 44 years; 125 patients had stage II and 75 had stage III disease. All were subjected to mastectomy. The influence of the following prognostic factors were evaluated: Age, histological grade, nodal status, number of positive nodes, tumor size, estrogen receptor status, menstrual status and as well as the sequence of radiotherapy and chemotherapy on 5-year locoregional disease free survival, 5-year systemic disease-free survival, and 5-year overall survival. Results: The 5-year locoregional disease free survival was 90.9% for the entire patient population. Nodal status, number of positive nodes and estrogen receptor status were prognostically significant for locoregional recurrence. The 5-year systemic disease-free survival was 67.6% for the whole group. On univariate analysis, the presence of positive axillary nodes, grade III tumor, ER-negative disease and radiotherapy first followed by chemotherapy, were independent poor risk factors for systemic recurrence. The 5-year overall survival was 71.8%. On univariate analysis, the presence of positive axillary nodes, grade III tumor, ER-negative disease and radiotherapy first followed by chemotherapy, were independent poor risk factors for death from breast cancer. Conclusions: In patients with breast cancer, a treatment protocol consisting of 6 cycles of CT followed by RT resulted in a better 5-year OS and DPS, and was easier to administer when compared with other treatment protocols. Ideal candidates are those with early-stage, age >35 years, low tumor grade, positive ER, and

  9. Salivary Gland Tumors Treated With Adjuvant Intensity-Modulated Radiotherapy With or Without Concurrent Chemotherapy

    Purpose: To analyze the recent single-institution experience of patients with salivary gland tumors who had undergone adjuvant intensity-modulated radiotherapy (IMRT), with or without concurrent chemotherapy. Patients and Methods: We performed a retrospective analysis of 35 salivary gland carcinoma patients treated primarily at the Dana-Farber Cancer Institute between 2005 and 2010 with surgery and adjuvant IMRT. The primary endpoints were local control, progression-free survival, and overall survival. The secondary endpoints were acute and chronic toxicity. The median follow-up was 2.3 years (interquartile range, 1.2–2.8) among the surviving patients. Results: The histologic types included adenoid cystic carcinoma in 15 (43%), mucoepidermoid carcinoma in 6 (17%), adenocarcinoma in 3 (9%), acinic cell carcinoma in 3 (9%), and other in 8 (23%). The primary sites were the parotid gland in 17 (49%), submandibular glands in 6 (17%), tongue in 4 (11%), palate in 4 (11%), and other in 4 (11%). The median radiation dose was 66 Gy, and 22 patients (63%) received CRT. The most common chemotherapy regimen was carboplatin and paclitaxel (n = 14, 64%). A trend was seen for patients undergoing CRT to have more adverse prognostic factors, including Stage T3-T4 disease (CRT, n = 12, 55% vs. n = 4, 31%, p = .29), nodal positivity (CRT, n = 8, 36% vs. n = 1, 8%, p = .10), and positive margins (n = 13, 59% vs. n = 5, 38%, p = .30). One patient who had undergone CRT developed an in-field recurrence, resulting in an overall actuarial 3-year local control rate of 92%. Five patients (14%) developed distant metastases (1 who had undergone IMRT only and 4 who had undergone CRT). Acute Grade 3 mucositis, esophagitis, and dermatitis occurred in 8%, 8%, and 8% (1 each) of IMRT patients and in 18%, 5%, and 14% (4, 1, and 3 patients) of the CRT group, respectively. No acute Grade 4 toxicity occurred. The most common late toxicity was Grade 1 xerostomia (n = 8, 23%). Conclusions: Treatment of

  11. A Prospective Randomized Study of Adjuvant Chemotherapy in Completely Resected Stage Ⅲ-N2 Non Small Cell Lung Cancer

    2007-01-01

    Objective: To evaluate the effect of postoperative adjuvant chemotherapy on survival after complete resection of stage Ⅲ-N2 non-small-cell lung cancer. Methods: From Jan. 1999 to Dec. 2003, one-hundred and fifty patients, who were diagnosed as stage Ⅲ-N2 non-small cell lung cancer after operation, were randomly devided into chemotherapy group and control group. The former received four cycles of chemotherapy with NVB (25 mg/m2,D1, D5)/paclitaxel (175 mg/m2, DI) and Carboplatin (AUC=5, D1). Results: In chemotherapy group, 75.8% (68/79) of patients had finished the 4 cycles of chemotherapy and no one died of toxic effects of chemotherapy.Twenty-five percent of the patients had grade 3-4 neutropenia and 2% had febrile neutropenia. The median survival for the entire 150 patients was 879 d, with 1-year survival rate of 81%, 2-year survival rate of 59% and 3-year survival rate of 43%. There was no significant difference in median survival between chemotherapy and control group (897 d vs 821 d, P=0.0527), but there was significant difference in the 1-year and 2-year overall survival (94.71%, 76.28% vs 512 d, P=0.122), but there was significant difference in the 2-year survival rate between two groups with brain metastases (66.7% vs 37.6% P<0.05). The median survival after brain metastasis appeared was 190 days. Conclusion: Postoperative adjuvant chemotherapy does not significantly improve median survival among patients with completely resected stage Ⅱ-N2 non-small-cell lung cancer, but significantly improves the 1-year and 2-year overall survival. It neither decreases the incidence of brain metastasis but put off the time of brain metastasis.

    Purpose: Long-term survival rates for patients with resected pancreatic ductal adenocarcinoma (PDAC) have stagnated at 20% for more than a decade, demonstrating the need to develop novel adjuvant therapies. Gemcitabine-erlotinib therapy has demonstrated a survival benefit for patients with metastatic PDAC. Here we report the first phase 2 study of erlotinib in combination with adjuvant chemoradiation and chemotherapy for resected PDAC. Methods and Materials: Forty-eight patients with resected PDAC received adjuvant erlotinib (100 mg daily) and capecitabine (800 mg/m{sup 2} twice daily Monday-Friday) concurrently with intensity modulated radiation therapy (IMRT), 50.4 Gy over 28 fractions followed by 4 cycles of gemcitabine (1000 mg/m{sup 2} on days 1, 8, and 15 every 28 days) and erlotinib (100 mg daily). The primary endpoint was recurrence-free survival (RFS). Results: The median follow-up time was 18.2 months (interquartile range, 13.8-27.1). Lymph nodes were positive in 85% of patients, and margins were positive in 17%. The median RFS was 15.6 months (95% confidence interval [CI], 13.4-17.9), and the median overall survival (OS) was 24.4 months (95% CI, 18.9-29.7). Multivariate analysis with adjustment for known prognostic factors showed that tumor diameter >3 cm was predictive for inferior RFS (hazard ratio, 4.01; P=.001) and OS (HR, 4.98; P=.02), and the development of dermatitis was associated with improved RFS (HR, 0.27; P=.009). During CRT and post-CRT chemotherapy, the rates of grade 3/4 toxicity were 31%/2% and 35%/8%, respectively. Conclusion: Erlotinib can be safely administered with adjuvant IMRT-based CRT and chemotherapy. The efficacy of this regimen appears comparable to that of existing adjuvant regimens. Radiation Therapy Oncology Group 0848 will ultimately determine whether erlotinib produces a survival benefit in patients with resected pancreatic cancer.

    Objective: To explore the role of adjuvant chemotherapy for patients with ypT0-2N0 rectal cancer treated by preoperative chemoradiation therapy (PCRT) and radical resection. Patients and Methods: A national consortium of 10 institutions was formed, and patients with ypT0-2N0 mid- and low-rectal cancer after PCRT and radical resection from 2004 to 2009 were included. Patients were categorized into 2 groups according to receipt of additional adjuvant chemotherapy: Adj CTx (+) versus Adj CTx (−). Propensity scores were calculated and used to perform matched and adjusted analyses comparing relapse-free survival (RFS) between treatment groups while controlling for potential confounding. Results: A total of 1016 patients, who met the selection criteria, were evaluated. Of these, 106 (10.4%) did not receive adjuvant chemotherapy. There was no overall improvement in 5-year RFS as a result of adjuvant chemotherapy [91.6% for Adj CTx (+) vs 87.5% for Adj CTx (−), P=.18]. There were no differences in 5-year local recurrence and distant metastasis rate between the 2 groups. In patients who show moderate, minimal, or no regression in tumor regression grade, however, possible association of adjuvant chemotherapy with RFS would be considered (hazard ratio 0.35; 95% confidence interval 0.14-0.88; P=.03). Cox regression analysis after propensity score matching failed to show that addition of adjuvant chemotherapy was associated with improved RFS (hazard ratio 0.81; 95% confidence interval 0.39-1.70; P=.58). Conclusions: Adjuvant chemotherapy seemed to not influence the RFS of patients with ypT0-2N0 rectal cancer after PCRT followed by radical resection. Thus, the addition of adjuvant chemotherapy needs to be weighed against its oncologic benefits.

  18. Predominant histologic subtype in lung adenocarcinoma predicts benefit from adjuvant chemotherapy in completely resected patients: discovery of a holy grail?

    Russell, Prudence Anne; Wright, Gavin Michael

    2016-01-01

    The recently published 2015 World Health Organisation (WHO) classification of lung tumors, which is based on the 2011 International Association for the Study of Lung Cancer (IASLC)/American Thoracic Society (ATS)/European Respiratory Society (ATS) multidisciplinary classification, recommends diagnosis of resected lung adenocarcinoma according to the predominant histologic subtype. This has been shown to correlate with overall and disease-free survival (DFS) in many studies from four continents. Now classification according to predominant histologic subtype has been demonstrated to predict benefit from adjuvant chemotherapy in a subset of patients with completely resected lung adenocarcinoma previously included in the International Adjuvant Lung Cancer Trial (IALT), JBR.10, Cancer and Leukemia Group B (CALGB) 9633 and Adjuvant Navelbine International Trialist Association 01 (ANITA) adjuvant chemotherapy trials, all of which were part of the LACE-Bio study. This "hot-off-the press" landmark investigation further cements the clinical importance of classification of resected lung adenocarcinoma according to predominant histologic subtype and suggests that it could be a critical factor for patient stratification in future clinical trials.

  19. BMI Influences Prognosis Following Surgery and Adjuvant Chemotherapy for Lymph Node Positive Breast Cancer

    Vitolins, Mara Z.; Kimmick, Gretchen G.; Case, L. Douglas

    2016-01-01

    Increased body mass index (BMI) at diagnosis has been shown to be associated with an increased risk of disease recurrence and death. However, the association has not been consistent in the literature and may depend on several factors such as menopausal status, extent of disease, and receptor status. We performed a secondary analysis on what we believe is the largest prospective trial of adjuvant chemotherapy to assess the effect of BMI on prognosis in women with lymph node positive breast cancer. The study included 636 women with a median follow-up of over 13 years. Cox’s proportional hazards regression model was used to assess the effect of BMI on outcomes. Kaplan–Meier methods were used to estimate survival curves and log rank tests were used to assess differences in survival for BMI groups. We found that increased BMI was generally predictive of faster time to recurrence and decreased survival, but that the relationship was stronger for younger women, those with progesterone receptor negative disease and those with a greater number of lymph nodes that were positive.

    Fourteen patients with a variety of neoplasms not responsive to standard forms of therapy underwent whole body hyperthermia for a maximum 4 h at 41.8 degrees C. This was a phase-I cancer trial designed to develop whole body hyperthermia as an adjuvant to systemic chemotherapy. Intravenous analgesia was used to sedate patients, obviating the need for general endotracheal anesthesia. Hyperthermia was induced by means of a high-flow water perfusion suit. Cardiovascular performance was evaluated using a flow-directed pulmonary artery catheter. Patients developed a twofold mean increase in cardiac index without evidence of cardiac damage by ECG or creatine phosphokinase (CPK) isoenzymes. An acute fall in serum magnesium and phosphate and an acute rise in arterial pH, serum CPK values, and granulocyte count occurred in all patients. There were no clotting abnormalities. Toxicity included fatigue, diarrhea, nausea, and transient elevations in liver enzymes. Four patients were febrile for 36 h after initial defervescence. Peripheral neuropathy developed in four. These results show that with carefully monitored conditions whole body hyperthermia is feasible. PMID:426399

  1. Adjuvant chemotherapy of pT1a and pT1b breast carcinoma: results from the NEMESI study

    The prognosis of pT1a-pT1b breast cancer (BC) used to be considered very good, with a 10-y RFS of 90%. However, some retrospective studies reported a 10-y RFS of 81%–86% and suggested benefit from adjuvant systemic therapy. To evaluate the variables that determined the choice of adjuvant chemotherapy and the type of chemotherapy delivered in pT1a-pT1b BC, we analysed the small tumours enrolled in the NEMESI study. Out of 1,894 patients with pathological stage I-II BC enrolled in NEMESI, 402 (21.2%) were pT1a-pT1b. Adjuvant chemotherapy was delivered in 127/402 (31.59%). Younger age, grading G3, high proliferative index, ER-negative and HER2-positive status were significantly associated with the decision to administer adjuvant chemotherapy. An anthracycline without taxane regimen was administered in 59.1% of patients, anthracycline with taxane in 24.4%, a CMF-like regimen in 14.2% and taxane in 2.4%. Adjuvant chemotherapy was administered in 88.4% triple-negative and 73.46% HER2-positive pT1a-pT1b BC. Adjuvant trastuzumab was delivered in 30/49 HER2-positive BC (61.2%). Adjuvant chemotherapy was delivered in 31.59% T1a-pT1b BC treated at 63 Italian oncological centres from January 2008 to June 2008. The choice to deliver chemotherapy was based on biological prognostic factors. Anthracycline-based chemotherapy was administered in 83.5% patients

    2012-04-01

    Full Text Available Background: This prospective study assessed the efficacy of neoadjuvant and adjuvant chemotherapy on patients with high risk soft tissue sarcomasof the extremities.Methods: Enrolled patients received the following neoadjuvant chemotherapy: doxorubicin (75 mg/m2 on day1, ifosfamide (2.5 g/m2/d and mesna (20% of the ifosfamide dose from days1 to 3, repeated every three weeks for a total of three cycles, followed by surgery and radiotherapy. Patients received an additional three cycles ofadjuvant chemotherapy that was the same as the neoadjuvant protocol following completion of radiotherapy.Results: There were 52 patients enrolled in the study, of which 50 were included in data analysis. Neoadjuvant chemotherapy was completed by 90% of enrolled patients and 88% completed all planned chemotherapy. A total of 96% of patients underwent surgery and 92% of these had R0 resections. Postoperative radiotherapy was administered to 96% of patients. The estimated three-year local-regional failure was 10%. Estimated three-year rate for distant disease-free survival was 66% and overall survival was 88%. One patient died with treatment secondary to leukopenic sepsis and respiratory failure. Grades 3-4 toxicities were experienced by 86% of patients of which 84% were grades 3- 4 hematologic toxicities and 38% were grades 3-4 nonhematologic toxicities.Conclusion: The current protocol is feasible and associated with favorable distant disease-free survival, overall survival, and limb preservation. This protocol is tolerable and has a manageable toxicity level.

  4. The relevance of adjuvant therapy in primary carcinoma of the Fallopian tube, Stages I and II: Irradiation vs. chemotherapy

    Introduction: Primary carcinoma of the Fallopian tube (FTC) is a rare but extremely aggressive neoplasm. It must be expected to cause up to 40% of tumor-related deaths even in Stage I, and up to 57% in Stage II. Due to its rarity, there exist only a few and divergent reports on the value of adjuvant therapy. Therefore the present study aims at evaluating the influence of postoperative adjuvant therapy on FTC by studying the effects of irradiation and chemotherapy on the overall survival of patients in Stages I and II. Patients and Methods: We investigated 95 cases of FTC in Stages I (n = 66) and II (n = 29) in a retrospective multicenter study. Group I (n = 32) are patients who underwent a complete irradiation with cobalt or photon energies of 23 MV (administering a daily dose of 2 Gy resulted in a total of 45-52 Gy in the pelvic areas). Group II (n = 31) consists of those cases who received postoperative chemotherapy with platinum. Thirty-two women were excluded from this study because they had other chemotherapies, incomplete irradiation, or no adjuvant therapy at all. Results: Median survival time was 57 months in Group I patients (95% confidence interval 33-81 months), compared to 73 months (95% confidence interval, 68-78 months) in the chemotherapeutically treated Group II. This difference did not prove to be statistically significant (p = 0.476). If primary surgical therapy is included in the evaluation, and patients with total abdominal hysterectomy (TAH) and bilateral salpingo-oophorectomy (BSO) are compared to those with additional radical lymphadencetomy (TAH+BSO+lymph nodes), the latter group's overall survival essentially improves but fails to reach statistical significance. Their 5-year survival rate is 83% against 58% in the TAH+BSO group (p 0.12). Conclusion: Chemotherapy and irradiation are two adjuvant therapies that are similarly effective in FTC of Stages I and II, with chemotherapy being preferred at the present time.

    Between 1975 and 1991, 40 patients with newly diagnosed medulloblastoma were treated at the authors' institutions. After aggressive surgical resection 39/40 (98%) received craniospinal radiation therapy with a local boost to the posterior fossa and other macroscopically involved areas. A group of 29 patients was treated with adjuvant chemotherapy. The five-year actuarial survival and event-free survival were 75% and 65%, respectively. Survival was significantly better for patients treated after 1981 as compared to those treated between 1975 and 1980 (p=.02). Younger age (two to four years) was associated with a better prognosis (p=.02). The extend of resection, Chang-stage, radiation dose to posterior fossa and the use of chemotherapy did not significantly impact on survival and relapse-free survival. (orig.)

    With the increasing use of adjuvant chemotherapy for treating early breast cancer, febrile neutropenia management has become crucial. Guidelines for febrile neutropenia management are mostly based on a Caucasian population survey although ethnic differences are reported in terms of adverse events. We survey the current status of febrile neutropenia and risk factors in Japanese female breast cancer patients receiving neoadjuvant and adjuvant chemotherapy regimens potential for febrile neutropenia. Subsequently, we plan to conduct a multicenter prospective cohort study involving 1000 patients with operable breast cancer. With the current state of oral antibiotics being routinely prescribed without hematology tests, we survey febrile neutropenia based on two different definitions, namely, true febrile neutropenia: ≥37.5°C and Grade 4 neutropenia, and surrogate febrile neutropenia: ≥37.5°C and oral antibiotic and antipyretic intake. The comparison of true febrile neutropenia and surrogate febrile neutropenia incidences is anticipated to provide information on the safety and feasibility of chemotherapy management without performing blood tests.

  7. Efficacy and influencing factor analysis of GP regimen n postoperative adjuvant chemotherapy for non-small-cell lung cancer

    Objective: to observe the short-term efficacy of GP regimen in adjuvant chemotherapy in patients with non-small-cell lung cancer, and to study the factors influencing efficacy and analyze the adverse reactions. Methods: Clinical data of 68 NSCLC patients received postoperative adjuvant chemotherapy of GP regimen was retrospectively analyzed. Kaplan-Meier method was used to draw the disease-free survival curve. Log-rank time series analysis wa used between different subgroups; COX proportional hazards model was used for the univariate and multivariate analyses. Results: Of all the 68 cases, the median recurrence-free survival time was 33.7 months, 56 cases were followed up more than one year, and one year disease-free survival rate was 83.9% ; 25 cases were followed up more than two years, and two-year disease-free survival was 72.0% . Univariate analysis suggested that clinical stage (P<0.05), pathological type (P<0.05), degree of differentiation (P<0.05) significantly influenced the short-term efficacy. Multivariate analysis suggested that clinical stage (P<0.05), degree of differentiation (P<0.05) were the independent factors of the short-term efficacy. The major adverse reactions were stage 3 to 4 myelo-suppression including neutropenia (33.9% ), granulocytopenia (20.6% ), anemia (4.4% ), and thrombocytopenia (4.4% ), and stage 3 to 4 nausea and vomiting (10.3% ). Conclusion: The GP regimen is feasible, well-tolerated with a high disease control rate in one or two years in the adjuvant chemotherapy; clinical stage degree of differentiation are the independent factors of the short-term efficacy.

  8. Concurrent Radiotherapy and Gemcitabine for Unresectable Pancreatic Adenocarcinoma: Impact of Adjuvant Chemotherapy on Survival

    Purpose: To retrospectively analyze results of concurrent chemoradiotherapy (CCRT) using gemcitabine (GEM) for unresectable pancreatic adenocarcinoma. Methods and Materials: Records of 108 patients treated with concurrent external beam radiotherapy (EBRT) and GEM were reviewed. The median dose of EBRT in all 108 patients was 50.4 Gy (range, 3.6–60.8 Gy), usually administered in conventional fractionations (1.8–2 Gy/day). During radiotherapy, most patients received GEM at a dosage of 250 to 350 mg/m2 intravenously weekly for approximately 6 weeks. After CCRT, 59 patients (54.6%) were treated with adjuvant chemotherapy (AC), mainly with GEM. The median follow-up for all 108 patients was 11.0 months (range, 0.4–37.9 months). Results: Initial responses after CCRT for 85 patients were partial response: 26 patients, no change: 51 patients and progressive disease: 8 patients. Local progression was observed in 35 patients (32.4%), and the 2-year local control (LC) rate in all patients was 41.9%. Patients treated with total doses of 50 Gy or more had significantly more favorable LC rates (2-year LC rate, 42.9%) than patients treated with total doses of less than 50 Gy (2-year LC rate, 29.6%). Regional lymph node recurrence was found in only 1 patient, and none of the 57 patients with clinical N0 disease had regional lymph node recurrence. The 2-year overall survival (OS) rate and the median survival time in all patients were 23.5% and 11.6 months, respectively. Patients treated with AC had significantly more favorable OS rates (2-year OS, 31.8%) than those treated without AC (2-year OS, 12.4%; p < 0.0001). On multivariate analysis, AC use and clinical T stage were significant prognostic factors for OS. Conclusions: CCRT using GEM yields a relatively favorable LC rate for unresectable pancreatic adenocarcinoma, and CCRT with AC conferred a survival benefit compared to CCRT without AC.

  10. Induction chemotherapy, extrapleural pneumonectomy, and adjuvant radiotherapy for malignant pleural mesothelioma. Experience of Guy's and St Thomas' hospitals

    The treatment of malignant pleural mesothelioma (MPM) remains controversial. We present a prospective study of patients treated at our institution with neoadjuvant chemotherapy, extrapleural pneumonectomy (EPP), and radical radiotherapy. Patients with MPM who were eligible for EPP and multimodality therapy were included in this study. Staging was through computed tomography and positron emission tomography and computed tomography (PET/CT) scanning, video-assisted thoracoscopic surgery (VATS), and mediastinoscopy. Our protocol involved three cycles of cisplatin-based neoadjuvant chemotherapy followed by extrapleural pneumonectomy and adjuvant radiotherapy (54 Gy). All patients were followed up every 3-6 months until death. From March 2004 through October 2008, 25 patients were referred for EPP following neoadjuvant chemotherapy. EPP was performed in all but three patients, who were found to have T4 disease at surgery. Surgical complications included arrhythmias (28%), bronchopleural fistulas (12%), reoperations for bleeding (8%), acute respiratory distress syndrome (4%), pneumonia (4%), septicemia (4%), vocal cord palsy (4%), and Horner's syndrome (4%). The 30-day mortality was 4%. Adjuvant radiotherapy was administered to 81% of patients after EPP. Radiotherapy toxicities included thrombocytopenia, radiation pneumonitis, pulmonary embolus, radiation hepatitis, herpes zoster, transverse myelitis, and late constrictive pericarditis. Median survival from diagnosis was 12.8 months (95% confidence interval 7.8-17.7 months). One-year survival was 54.5%; 2-year survival was 18.2%. Disease progression occurred in 77.3% of patients. Nodal status (N0 disease versus N1-N2) or histology (epithelioid versus biphasic) had no significant impact on survival. Despite recent advances in chemotherapy, surgery, and radiotherapy, survival rates remain low for patients with MPM completing multimodality therapy including EPP. (author)

    Chemotherapy for early-stage breast cancer has lowered cancer recurrence and deaths. However, short-term mortality rates due to cancer or treatment in the general population remain largely unknown. In this study, we evaluate the short-term mortality rate and the determinants of such outcome among a cohort of older breast cancer patients treated with adjuvant chemotherapy. This is a population-based study based on the Surveillance, Epidemiology, and End Results Program (SEER)-Medicare and the Texas Cancer Registry (TCR)-Medicare databases. Patients diagnosed with early-stage breast cancer between 2003 and 2011 who were 66 years or older and were treated with adjuvant chemotherapy within 6 months of diagnosis were included. Short-term mortality was defined as death from any cause within one year of breast cancer diagnosis. Descriptive statistics and multivariable logistic regression modeling were used for the analysis. Of the 21,536 patients included, a total of 625 (2.9 %) died within one year of breast cancer diagnosis. In multivariate analysis, older age (using 66-70 as reference category; 71-75 years OR 1.31, 95 % CI 1.05-1.62; 76-80 years OR 1.73, 95 % CI 1.36-2.19; >80 years OR 3.48, 95 % CI 2.7-4.48) and higher comorbidity index (using Charlson score of 0 as a reference, those with score of 1 or >2 had higher risk OR 1.46, 95 % CI 1.19-1.8 and OR 2.98, 95 % CI 2.42-3.67, respectively) were associated with the increased risk of short-term mortality. Other factors significantly associated with the outcome were higher grade and stage, ER-negative status, poor census tract area, and mastectomy. The findings of this study revealed that, in this large cohort of older breast cancer patients treated with adjuvant chemotherapy, 2.9 % of the population died within one year of breast cancer diagnosis. Finally, it was concluded that tumor- and patient-related characteristics were associated with short-term death. Our findings add relevant information that can be

    Objective The aim of the present study was to investigate the ef ect of dendritic cel (DC)/cytokine-in-duced kil er cel (CIK) immunobiological cancer therapy in patients with triple-negative breast cancer (TNBC) who underwent adjuvant chemotherapy. Methods From January 2010 to October 2013, 120 patients with postoperative TNBC were recruited and included in the study. Patients were enrol ed in one of two groups according to whether they accepted DC/CIK immunobiological cancer therapy during adjuvant chemotherapy; the patients in the DC/CIK group underwent adjuvant chemotherapy combined with DC/CIK immunobiological cancer therapy, and the control group underwent adjuvant chemotherapy alone. When six cycles of adjuvant chemotherapy and six cycles of DC/CIK immunobiological cancer therapy had been completed, dif erences between the two groups with regard to quality of life (QoL), immunological indicators (CD3, CD4, CD8, and NK cel levels), disease-free survival (DFS), and side ef ects of chemotherapy and DC/CIK treatment were evaluated. Results In the DC/CIK group, the proportion of NK cel s and CD3+ and CD4+ T-cel subgroups significantly increased, and the proportion of CD8+ cel s decreased when they were compared before and after DC/CIK therapy (P Conclusion The DC/CIK treatment had potential benefits for patients with TNBC compared with the con-trol group, and was not associated with any obvious side ef ects. Therefore, DC/CIK therapy is a safe and ef ective method for the treatment of TNBC.

    For children with stage II testicular malignant germ cell tumors (MGCT), the survival is good with surgery and adjuvant chemotherapy. However, there is limited data on surgical results for cases in which there was no imaging or pathologic evidence of residual tumor, but in which serum tumor markers either increased or failed to normalize after an appropriate period of half-life time post-surgery. To determine the use of chemotherapy for children with stage II germ cel tumors, we analyzed the outcomes (relapse rate and overall survival) of patients who were treated at the Sun Yat-sen University Cancer Center between January 1990 and May 2013. Twenty-four pediatric patients with a median age of 20 months (range, 4 months to 17 years) were enrol ed in this study. In 20 cases (83.3%), the tumors had yolk sac histology. For definitive treatment, 21 patients underwent surgery alone, and 3 patients received surgery and adjuvant chemotherapy. No relapse was observed in the 3 patients who received adjuvant chemotherapy, whereas relapse occurred in 16 of the 21 patients (76.2%) treated with surgery alone. There were a total of 2 deaths. Treatment was stopped for 1 patient, who died 3 months later due to the tumor. The other patient achieved complete response after salvage treatment, but developed lung and pelvic metastases 7 months later and died of the tumor after stopping treatment. For children treated with surgery alone and surgery combined with adjuvant chemotherapy, the 3-year event-free survival rates were 23.8% and 100%, respectively (P=0.042), and the 3-year overal survival rates were 90.5%and 100%, respectively (P=0.588). These results suggest that adjuvant chemotherapy can help to reduce the recurrence rate and increase the survival rate for patients with stage II germ cel tumors.

  17. Differential response of immunohistochemically defined breast cancer subtypes to anthracycline-based adjuvant chemotherapy with or without paclitaxel.

    George Fountzilas

    Full Text Available BACKGROUND: The aim of the present study was to investigate the efficacy of adjuvant dose-dense sequential chemotherapy with epirubicin, paclitaxel, and CMF in subgroups of patients with high-risk operable breast cancer, according to tumor subtypes defined by immunohistochemistry (IHC. MATERIALS AND METHODS: Formalin-fixed paraffin-embedded (FFPE tumor tissue samples from 1,039 patients participating in two adjuvant dose-dense sequential chemotherapy phase III trials were centrally assessed in tissue micro-arrays by IHC for 6 biological markers, that is, estrogen receptor (ER, progesterone receptor (PgR, HER2, Ki67, cytokeratin 5 (CK5, and EGFR. The majority of the cases were further evaluated for HER2 amplification by FISH. Patients were classified as: luminal A (ER/PgR-positive, HER2-negative, Ki67(low; luminal B (ER/PgR-positive, HER2-negative, Ki67(high; luminal-HER2 (ER/PgR-positive, HER2-positive; HER2-enriched (ER-negative, PgR-negative, HER2-positive; triple-negative (TNBC (ER-negative, PgR-negative, HER2-negative; and basal core phenotype (BCP (TNBC, CK5-positive and/or EGFR-positive. RESULTS: After a median follow-up time of 105.4 months the 5-year disease-free survival (DFS and overall survival (OS rates were 73.1% and 86.1%, respectively. Among patients with HER2-enriched tumors there was a significant benefit in both DFS and OS (log-rank test; p = 0.021 and p = 0.006, respectively for those treated with paclitaxel. The subtype classification was found to be of both predictive and prognostic value. Setting luminal A as the referent category, the adjusted for prognostic factors HR for relapse for patients with TNBC was 1.91 (95% CI: 1.31-2.80, Wald's p = 0.001 and for death 2.53 (95% CI: 1.62-3.60, p<0.001. Site of and time to first relapse differed according to subtype. Locoregional relapses and brain metastases were more frequent in patients with TNBC, while liver metastases were more often seen in patients with HER2-enriched tumors

  19. Impact of Postoperative Radiation Therapy on Survival in Patients With Complete Resection and Stage I, II, or IIIA Non-Small-Cell Lung Cancer Treated With Adjuvant Chemotherapy: The Adjuvant Navelbine International Trialist Association (ANITA) Randomized Trial

    Purpose: To study the impact of postoperative radiation therapy (PORT) on survival in the Adjuvant Navelbine International Trialist Association (ANITA) randomized study of adjuvant chemotherapy. Methods and Materials: ANITA is a randomized trial of adjuvant cisplatin and vinorelbine chemotherapy vs. observation in completely resected non-small-cell lung carcinoma (NSCLC) Stages IB to IIIA. Use of PORT was recommended for pN+ disease but was not randomized or mandatory. Each center decided whether to use PORT before initiation of the study. We describe here the survival of patients with and without PORT within each treatment group of ANITA. No statistical comparison of survival was performed because this was an unplanned subgroup analysis. Results: Overall, 232 of 840 patients received PORT (33.3% in the observation arm and 21.6% in the chemotherapy arm). In univariate analysis, PORT had a deleterious effect on the overall population survival. Patients with pN1 disease had an improved survival from PORT in the observation arm (median survival [MS] 25.9 vs. 50.2 months), whereas PORT had a detrimental effect in the chemotherapy group (MS 93.6 months and 46.6 months). In contrast, survival was improved in patients with pN2 disease who received PORT, both in the chemotherapy (MS 23.8 vs. 47.4 months) and observation arm (median 12.7 vs. 22.7 months). Conclusion: This retrospective evaluation suggests a positive effect of PORT in pN2 disease and a negative effect on pN1 disease when patients received adjuvant chemotherapy. The results support further evaluation of PORT in prospectively randomized studies in completely resected pN2 NSCLC

  20. A retrospective study of the value of chemotherapy as adjuvant therapy to surgery and radiotherapy in grade 3 and 4 gliomas

    Gundersen, S.; Lote, K.; Watne, K. [Department of Medical Oncology and Radiotherapy, The Norwegian Radium Hospital, Montebello, N-0310 Oslo (Norway)

    1998-09-01

    The aim of this retrospective study was to evaluate the effect of adjuvant chemotherapy among patients <55 years of age with anaplastic gliomas (histological grade 3, n=85) with four cycles 4 weeks apart of 160 mg carmustine (BCNU) infused into the internal carotid artery, combined with vincristine 2 mg and procarbazine 50 mgx3 for 1 week (i.a.BCNU-PV) versus no adjuvant chemotherapy. In glioblastomas (histological grade 4, n=257) the same chemotherapy was evaluated versus two cycles 4 weeks apart of 160 mg lomustine (CCNU) orally instead of BCNU, combined with vincristine and procarbazine (PCV) versus no chemotherapy. All patients in both groups received radiotherapy. Among glioblastoma patients <55 years of age there was a significant (P=0.03), but moderately increased survival in the i.a.BCNU-PV group versus the two other arms that did not differ from each other. This difference could be explained by an uneven distribution of prognostic factors, especially age group (<50 years versus 50-54 years) in favour of the i.a.BCNU-PV group. In anaplastic gliomas, the median survival in the i.a.BCNU-PV group was 80 months versus 25 months for the no chemotherapy arm (P=0.004). No significant differences in the distribution of prognostic factors were found between the two therapy arms. We suggest that the role of adjuvant chemotherapy in glioblastomas is unclear, while i.a.BCNU-PV as adjuvant chemotherapy among patients <55 years of age and with anaplastic gliomas increased survival markedly.

  1. Preliminary Results of a Prospective Randomized Trial Comparing Concurrent Chemoradiotherapy Plus Adjuvant Chemotherapy With Radiotherapy Alone in Patients With Locoregionally Advanced Nasopharyngeal Carcinoma in Endemic Regions of China

    Purpose: A prospective randomized trial was performed to evaluate the efficacy of concurrent chemotherapy and adjuvant chemotherapy in patients with locoregionally advanced nasopharyngeal carcinoma (NPC) in endemic regions of China. Methods and Materials: Between July 2002 and September 2005, 316 eligible patients were randomly assigned to receive either radiotherapy alone (RT) or chemoradiotherapy concurrent with adjuvant chemotherapy (CRT). All patients received 70 Gy in 7 weeks using standard RT portals and techniques. The CRT patients were given concurrent cisplatin (40 mg/m2 on Day 1) weekly during RT, followed by cisplatin (80 mg/m2 on Day 1) and fluorouracil (800 mg/m2 on Days 1-5) every 4 weeks (Weeks 5, 9, and 13) for three cycles after completion of RT. All patients were analyzed by intent-to-treat analysis. Results: The two groups were well-balanced in all prognostic factors and RT parameters. The CRT group experienced significantly more acute toxicity (62.6% vs. 32%, p = 0.000). A total of 107 patients (68%) and 97 patients (61%) completed all cycles of concurrent chemotherapy and adjuvant chemotherapy, with a median follow-up time of 29 months. The 2-year overall survival rate, failure-free survival rate, distant failure-free survival rate, and locoregional failure-free survival rate for the CRT and RT groups were 89.8% vs. 79.7% (p = 0.003), 84.6% vs. 72.5% (p = 0.001), 86.5% vs. 78.7% (p = 0.024), and 98.0% vs. 91.9% (p = 0.007), respectively. Conclusions: This trial demonstrated the significant survival benefits of concurrent chemotherapy plus adjuvant chemotherapy in patients with locoregionally advanced NPC in endemic regions of China

    2016-01-01

    Background and Objective Studies examining the prognostic value of the BRAF mutation on relapse-free survival (RFS), disease-free survival (DFS) and overall survival (OS) in stage II/III colorectal cancer (CRC) patients receiving curative resection and adjuvant chemotherapy so far showed discrepant results. Therefore, a meta-analysis of relevant studies was performed for clarification. Methods Randomized trials of stage II/III colorectal cancer treated with curative resection followed by adjuvant chemotherapy were selected to conduct a meta-analysis. The necessary descriptive and statistical information such as hazard ratios (HRs) and 95% confidence intervals (CIs) were derived from published survival data. Results Seven phase III randomized clinical trials (RCTs) including 1,035 BRAF mutation stage II/III CRC patients receiving curative resection and adjuvant chemotherapy were analyzed. Overall, BRAF mutation resulted in poorer OS (HR = 1.42, 95% CI: 1.25–1.60; P < 0.00001), and poorer DFS (HR = 1.26, 95% CI: 1.07–1.48, P = 0.006) compared with BRAF wild-type CRC. The prognostic role on RFS could not be elucidated in the meta-analysis because of limited data. Conclusions BRAF mutation was significantly related with shorter DFS and OS among stage II/III CRC patients receiving adjuvant chemotherapy after curative resection. Its prognostic role for RFS needs to be further analyzed when more data is available. PMID:27138801

  4. Tumor tissue levels of Tissue Inhibitor of Metalloproteinases-1 (TIMP-1) and outcome following adjuvant chemotherapy in premenopausal lymph node-positive breast cancer patients: A retrospective study

    We have previously demonstrated that high tumor tissue levels of TIMP-1 are associated with no or limited clinical benefit from chemotherapy with CMF and anthracyclines in metastatic breast cancer patients. Here, we extend our investigations to the adjuvant setting studying outcome after adjuvant chemotherapy in premenopausal lymph node-positive patients. We hypothesize that TIMP-1 high tumors are less sensitive to chemotherapy and accordingly that high tumor tissue levels are associated with shorter survival. From our original retrospectively collected tumor samples we selected a group of 525 pre-menopausal lymph node-positive patients (adjuvant treatment: CMF, 324 patients; anthracycline-based, 99 patients; no adjuvant chemotherapy, 102 patients). TIMP-1 levels were measured using ELISA in cytosolic extracts of frozen primary tumors. TIMP-1 was analyzed as a continuous variable and as a dichotomized one using the median TIMP-1 concentration as a cut point between high and low TIMP-1 groups. We analyzed the benefit of adjuvant CMF and anthracyclines in univariate and multivariable survival models; endpoints were disease-free (DFS) and overall survival (OS). In this selected cohort of high-risk patients, and in the subgroup of patients receiving no adjuvant therapy, TIMP-1 was not associated with prognosis. In the subgroup of patients treated with anthracyclines, when analyzed as a continuous variable we observed a tendency for increasing TIMP-1 levels to be associated with shorter DFS (multivariable analysis, HR 1.75, 95% CI 1.00-3.07, P = 0.05) and a significant association between increasing TIMP-1 and shorter OS in both univariate (HR 3.52, 95% CI 1.54-8.06, P = 0.003) and multivariable analyses (HR 4.19, 95% CI 1.67-10.51, P = 0.002). No statistically significant association between TIMP-1 and DFS was observed in the CMF-treated patients although high TIMP-1 was associated with shorter OS when analyzed as a dichotomized variable (HR 1.64, 95% CI 1.02-2.65, P

    2016-01-01

    Problems with attention and symptom distress are common clinical features reported by women who receive adjuvant chemotherapy for breast cancer. Mindfulness practice significantly improves attention and mindfulness programs significantly reduce symptom distress in patients with cancer, and, more specifically, in women with breast cancer. Recently, a pilot investigation of a music therapy program, built on core attitudes of mindfulness practice, reported significant benefits of enhanced attention and decreased negative mood and fatigue in women with breast cancer. This paper delineates the design and development of the mindfulness-based music therapy (MBMT) program implemented in that pilot study and includes clients' narrative journal responses. Conclusions and recommendations, including recommendation for further exploration of the function of music in mindfulness practice are provided. PMID:27517966

    Full Text Available Objectives: To explore alternate modality of treatment in patients of advanced cancer cervix by neo-adjuvant chemotherapy (NACT followed by External Beam Radiotherapy (ERT and Brachytherapy (BT. Short- (6 months and long- (12 months term follow-up data from these patients were compared with the retrospective data from an urban cancer centre, where standard protocol of concurrent chemo-radiotherapy is practiced. Materials and Methods: Two hundred patients of advanced cervical cancer, treated at our rural cancer centre between January 2007 and December 2007, were included in the study arm (Group A. These patients received three cycles of neo-adjuvant chemotherapy with Cisplatin, Bleomycin, and Vincristine before External-Beam Radiotherapy (EBT followed by brachytherapy. Patients in the control arm (Group B of an urban cancer centre, received EBT with weekly concomitant Cisplatin, followed by brachytherapy. Short- (6 months and long- (12 months term follow-up data from our patients were compared with the retrospective data from the urban cancer centre. Results and Analysis: Complete response rate was comparatively higher among patients of Group A, also correspondingly proportion of patients showing progressive disease and stable disease was lower among them. Local treatment failure was 87.5% among patients from Group A and 94.4% in Group B patients. Concomitant chemoradiation (CRT was associated with more GI toxicities. Conclusion: Our result suggests NACT arm is as effective as CRT arm in respect of complete response with less pelvic failure and G.I toxicities. Further follow-up data are needed before arriving at a definite conclusion.

    Neo-adjuvant chemotherapy (NAC) is used to facilitate radical surgery for initially irresectable or locally advanced breast cancer. The indication for NAC has been extended to clinically node negative (cN0) patients in whom adjuvant systemic therapy is foreseen. A population-based study was conducted to evaluate the increasing use of NAC, breast conserving surgery (BCS) after NAC and timing of the sentinel node biopsy (SNB). All female breast cancer patients, treated in 10 hospitals in the Eindhoven Cancer Registry area in the Netherlands between January 2003 and June 2012 were included (N = 18,427). In total, 1,402 patients (7.6%) received NAC. The administration increased from 2.5% in 2003 to 13.0% in 2011 (p Downsizing of the tumor and BCS are achieved increasingly. In 2011, in three hospitals NAC was administered in 20% (p < 0.001). Of the 1,402 patients with NAC, 495 patients underwent SNB, 91.5% of whom prior to NAC. In the Netherlands up to one in eight patients receive NAC. The administration of NAC and the percentage of BCS increased over the past decade, especially in cT2 tumors. Considerable hospital variation in the administration of NAC exists. PMID:26945566

    Full Text Available Abstract Background This study examined the association between overall survival and Glutathione S-transferase Pi (GST Pi expression and genetic polymorphism in stage C colon cancer patients after resection alone versus resection plus 5-fluourouracil-based adjuvant chemotherapy. Methods Patients were drawn from a hospital registry of colorectal cancer resections. Those receiving chemotherapy after it was introduced in 1992 were compared with an age and sex matched control group from the preceding period. GST Pi expression was assessed by immunohistochemistry. Overall survival was analysed by the Kaplan-Meier method and Cox regression. Results From an initial 104 patients treated with chemotherapy and 104 matched controls, 26 were excluded because of non-informative immunohistochemistry, leaving 95 in the treated group and 87 controls. Survival did not differ significantly among patients with low GST Pi who did or did not receive chemotherapy and those with high GST Pi who received chemotherapy (lowest pair-wise p = 0.11 whereas patients with high GST Pi who did not receive chemotherapy experienced markedly poorer survival than any of the other three groups (all pair-wise p Conclusion Stage C colon cancer patients with low GST Pi did not benefit from 5-fluourouracil-based adjuvant chemotherapy whereas those with high GST Pi did.

  10. Hyperfractionated craniospinal radiotherapy and adjuvant chemotherapy for children with newly diagnosed medulloblastoma and other primitive neuroectodermal tumors

    Purpose: This single-institution Phase I/II study conducted from 1989 to 1995 evaluates the feasibility of a multi-modality protocol combining hyperfractionated craniospinal radiotherapy (HFRT) followed by adjuvant chemotherapy in 23 patients with newly diagnosed primitive neuroectodermal tumors (PNET) arising in the central nervous system. Methods and Materials: All 23 patients had a histologically confirmed PNET and were over 3 years of age at diagnosis. The eligibility criteria for PNET patients with cerebellar primaries (medulloblastoma) included either a high T stage (T3b or 4) or high M stage (M1-3). All patients with noncerebellar primaries were eligible regardless of T or M stage. The median age of the 23 patients was 9 years (mean 3-25); 11 were female. The primary tumor arose in the cerebellum in 19. Of these medulloblastoma patients, 15 had high T stages (T3b or T4) with large locally invasive tumors and no evidence of metastases (M0), constituting Group 1. Thirteen (86%) of these patients had gross total resections. Four other medulloblastoma patients had both high T and high M stages, constituting Group 2. Group 3 consisted of four other patients with exocerebellar primaries (two brain, one brain stem, and one cauda equina), three of whom were M3. Hyperfractionated radiotherapy was administered within 4 weeks of surgery. Twice-daily 1-Gy fractions were administered separated by 4-6 h. The total dose to the primary intracranial tumor and other areas of measurable intracranial disease was 72 Gy. The prophylactic craniospinal axis dose was 36 Gy, and boosts of 44-56 Gy were administered to metastatic spinal deposits. Following radiotherapy, monthly courses of multiagent chemotherapy were administered sequentially (cyclophosphamide-vincristine followed by cisplatin-etoposide followed by carboplatin-vincristine) for a total of 9 months. Results: All patients completed radiotherapy as planned. Only three patients lost >10% of their body weight. One patient

    Surgical resection is the only option of cure for patients with metastatic colorectal cancer (CRC). However, the risk of recurrence within 18 mo after metastasectomy is around 75% and the liver is the most frequent site of relapse. The current international guidelines recommend an adjuvant therapy after surgical resection of CRC metastases despite the lower level of evidence (based on the quality of studies in this setting). However, there is still no standard treatment and the effective role...

  13. Mastectomy With Immediate Expander-Implant Reconstruction, Adjuvant Chemotherapy, and Radiation for Stage II-III Breast Cancer: Treatment Intervals and Clinical Outcomes

    Purpose: To determine intervals between surgery and adjuvant chemotherapy and radiation in patients treated with mastectomy with immediate expander-implant reconstruction, and to evaluate locoregional and distant control and overall survival in these patients. Methods and Materials: Between May 1996 and March 2004, 104 patients with Stage II-III breast cancer were routinely treated at our institution under the following algorithm: (1) definitive mastectomy with axillary lymph node dissection and immediate tissue expander placement, (2) tissue expansion during chemotherapy, (3) exchange of tissue expander for permanent implant, (4) radiation. Patient, disease, and treatment characteristics and clinical outcomes were retrospectively evaluated. Results: Median age was 45 years. Twenty-six percent of patients were Stage II and 74% Stage III. All received adjuvant chemotherapy. Estrogen receptor staining was positive in 77%, and 78% received hormone therapy. Radiation was delivered to the chest wall with daily 0.5-cm bolus and to the supraclavicular fossa. Median dose was 5040 cGy. Median interval from surgery to chemotherapy was 5 weeks, from completion of chemotherapy to exchange 4 weeks, and from exchange to radiation 4 weeks. Median interval from completion of chemotherapy to start of radiation was 8 weeks. Median follow-up was 64 months from date of mastectomy. The 5-year rate for locoregional disease control was 100%, for distant metastasis-free survival 90%, and for overall survival 96%. Conclusions: Mastectomy with immediate expander-implant reconstruction, adjuvant chemotherapy, and radiation results in a median interval of 8 weeks from completion of chemotherapy to initiation of radiation and seems to be associated with acceptable 5-year locoregional control, distant metastasis-free survival, and overall survival

  14. Breast MRI for monitoring response of primary breast cancer to neo-adjuvant chemotherapy

    The objective of the present study was to monitor response to preoperative chemotherapy with breast MRI in patients with large breast cancer. Fifty-eight women in whom core biopsy had confirmed the presence of breast carcinoma underwent breast MRI prior to beginning chemotherapy and before surgical excision. In 24 cases patients underwent one or two additional examinations during chemotherapy to monitor their progress. Breast MRI included both T2-weighted spin-echo sequences and T1-weighted gradient-echo sequences before and 1, 2, 3, and 8 min after bolus injection of gadolinium-DTPA. Tumor size and the dynamic contrast medium uptake patterns of the respective carcinomas were evaluated and compared with the final histology findings. Based on their MR tomographic findings (change in tumor size and intensity of contrast media uptake), patients were assigned to groups with non-response (NR), partial response (PR), and complete response (CR). Based on MR tomographic findings, there were 12 patients in the NR group, 34 in the PR group, and 12 in the CR group. In NR group contrast medium uptake tended to increase or show no more than minimal decrease. Diagnostic accuracy for assigning patients to the NR group was 83.3% and to the PR group 82.4%. In patients whose tumors showed only slight response to chemotherapy, breast MRI proved very reliable in determining the size of the lesions. In patients whose tumors displayed significant response and in the CR group, the size of the residual tumor was underestimated in 8 of 12 cases. In 66.7% of patients in the CR group histology revealed residual tumor masses in areas up to 5 cm in diameter. During chemotherapy, intensity of contrast medium uptake decreased in 88.2% of patients with PR and in all patients with CR. Reliable determination of response was possible within 6 weeks following the initiation of chemotherapy. Breast MRI is suitable as a monitoring method. The determination of residual tumor size is unreliable in

  15. Genomic signatures for predicting survival and adjuvant chemotherapy benefit in patients with non-small-cell lung cancer

    Van Laar Ryan K

    2012-07-01

    Full Text Available Abstract Background Improved methods are needed for predicting prognosis and the benefit of delivering adjuvant chemotherapy (ACT in patients with non-small-cell lung cancer (NSCLC. Methods A novel prognostic algorithm was identified using genomic profiles from 332 stage I-III adenocarcinomas and independently validated on a separate series of 264 patients with stage I-II tumors, compiled from five previous studies. The prognostic algorithm was used to interrogate genomic data from a series of patients treated with adjuvant chemotherapy. Those genes associated with outcome in the adjuvant treatment setting, independent to prognosis were used to train an algorithm able to classify a patient as either a responder or non-responder to ACT. The performance of this signature was independently validated on a separate series of genomic profiles from patients enrolled in a randomized controlled trial of cisplatin/vinorelbine vs. observation alone (JBR.10. Results NSCLC patients exhibiting the high-risk, poor-prognosis form of the 160-gene prognosis signature experienced a 2.80-times higher rate of 5-year disease specific death (log rank P  Separately, NSCLC patients with the 37-gene ACT-response signature (n = 70, 64 %, benefited significantly from cisplatin/vinorelbine (adjusted HR: 0.23, P = 0.0032. For those patients predicted to be responders, receiving this form of ACT conferred a 25 % improvement in the probability of 5-year-survival, compared to observation alone and adjusted for covariates. Conversely, in those patients predicted to be non-responders, ACT was observed to offer no significant survival benefit (adjusted HR: 0.55, P = 0.32. The two gene signatures overlap by one gene only SPSB3, which interacts with the oncogene MET. In this study, higher levels of SPSB3 which were associated with favorable prognosis and benefit from ACT. Conclusions These complimentary prognostic and predictive gene signatures may assist

  16. A phase II study evaluating neo-/adjuvant EIA chemotherapy, surgical resection and radiotherapy in high-risk soft tissue sarcoma

    The role of chemotherapy in high-risk soft tissue sarcoma is controversial. Though many patients undergo initial curative resection, distant metastasis is a frequent event, resulting in 5-year overall survival rates of only 50-60%. Neo-adjuvant and adjuvant chemotherapy (CTX) has been applied to achieve pre-operative cytoreduction, assess chemosensitivity, and to eliminate occult metastasis. Here we report on the results of our non-randomized phase II study on neo-adjuvant treatment for high-risk STS. Patients with potentially curative high-risk STS (size ≥ 5 cm, deep/extracompartimental localization, tumor grades II-III [FNCLCC]) were included. The protocol comprised 4 cycles of neo-adjuvant chemotherapy (EIA, etoposide 125 mg/m2 iv days 1 and 4, ifosfamide 1500 mg/m2 iv days 1 - 4, doxorubicin 50 mg/m2 day 1, pegfilgrastim 6 mg sc day 5), definitive surgery with intra-operative radiotherapy, adjuvant radiotherapy and 4 adjuvant cycles of EIA. Between 06/2005 and 03/2010 a total of 50 subjects (male = 33, female = 17, median age 50.1 years) were enrolled. Median follow-up was 30.5 months. The majority of primary tumors were located in the extremities or trunk (92%), 6% originated in the abdomen/retroperitoneum. Response by RECIST criteria to neo-adjuvant CTX was 6% CR (n = 3), 24% PR (n = 12), 62% SD (n = 31) and 8% PD (n = 4). Local recurrence occurred in 3 subjects (6%). Distant metastasis was observed in 12 patients (24%). Overall survival (OS) and disease-free survival (DFS) at 2 years was 83% and 68%, respectively. Multivariate analysis failed to prove influence of resection status or grade of histological necrosis on OS or DFS. Severe toxicities included neutropenic fever (4/50), cardiac toxicity (2/50), and CNS toxicity (4/50) leading to CTX dose reductions in 4 subjects. No cases of secondary leukemias were observed so far. The current protocol is feasible for achieving local control rates, as well as OS and DFS comparable to previously published data on

    For many women with non-metastatic breast cancer, adjuvant chemotherapy prevents recurrence and extends survival. Women who discontinue chemotherapy early may reduce those benefits, but little is known about what predicts early discontinuation. We sought to determine prospectively the rate and reasons for early discontinuation of adjuvant chemotherapy in women with breast cancer. We conducted a prospective cohort study among three U.S. health care organizations. Of 1158 women with newly diagnosed non-metastatic breast cancer, 2006-2010, we analyzed 445 (38.4 %) patients who initiated standard adjuvant chemotherapy as defined by accepted guidelines. We interviewed patients at baseline and twice during treatment regarding sociodemographic/psychosocial factors and treatment decision-making and collected clinical data. They were categorized according to the number of cycles required by the chemotherapy regimen they had initiated. The outcome was early discontinuation (4 cycles of therapy (18.1 % for longer regimens, 7.4 % for 4 cycles) (odds ratio [OR] 2.59, 95 % CI 1.32-5.08), controlling for race, age, stage, hormone receptor status, social support, optimism, spirituality, stress, and physical symptoms. Higher levels of psychological symptoms on the Memorial symptom assessment scale also increased the odds of early discontinuation (OR 1.92, 95 % CI 0.998-3.68). The large majority of patients who initiated adjuvant chemotherapy for breast cancer completed their prescribed regimens, but early discontinuation was associated with lengthier regimens and, with borderline statistical significance, for those with psychological side effects.

  19. Neoadjuvant and adjuvant chemotherapy combined with anatomical resection of feline injection-site sarcoma: results in 21 cats.

    Bray, J; Polton, G

    2016-06-01

    This study assesses the outcome of two combined treatment strategies for the treatment of feline injection-site sarcoma (FISS). Twenty-one cats with primary or recurrent FISS received 3 cycles of neoadjuvant chemotherapy with epirubicin (25 mg m(-2) ), then an anatomical resection of the entire muscle compartment containing the tumour was performed based on the findings of co-axial imaging. Cats then received a further 3 cycles of adjuvant chemotherapy. Follow-up was performed by telephone contact with a median follow-up time of 1072 days. Three cats (14%) developed local tumour recurrence at days 264, 664 and 1573 after surgery. A median survival time could not be calculated as over 80% of the study population remained alive or were censored due to death from other causes. When compared to historical controls, the results of this study demonstrate superior rates of tumour-free survival and disease-free interval. PMID:24502401

    The aim of this study was to evaluate the efficacy and safety of neo-adjuvant chemotherapy (NACT) versus radical surgery (RS) for patients with cervical cancer. A meta-analysis of randomized controlled trials (RCT) of NACT + RS versus RS alone for patients with cervical cancer was performed according to the guidelines of the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. The following electronic databases were searched from their inception to April 2015: PUBMED, EMBASE and Cochrane Library. Statistical analysis was done using REVIEW MANAGER 5.3. Five RCT involving 739 patients were studied. There were significant differences between the NACT + RS and the RS-alone groups for positive lymph nodes (OR, 0.45; 95%CI: 0.29-0.70) and parametrial infiltration (OR, 0.48; 95% CI: 0.25-0.92), while treatment efficacy did not differ significantly for 5-year overall survival rate (OR, 1.17; 95% CI: 0.85-1.61), 5-year disease-free survival rate (OR, 1.09; 95% CI: 0.77-1.56) or recurrence rate (OR, 1.17; 95% CI: 0.85-1.61). The results also indicated that chemotherapy-related toxicity was well tolerated. For patients with cervical cancer, NACT could significantly reduce the number of positive lymph nodes and the level of parametrial infiltration compared with RS alone, and be well tolerated.

This review analyzes the evidence from metaanlyses, major multiinstitutional prospective trials, retrospective institutional series and systematic reviews in breast cancer to det...

  3. Impact of adjuvant chemotherapy on cosmesis and complications in Stages I and II carcinoma of the breast treated by biopsy and radiation therapy

    Cosmesis and complication rates were examined in patients with early stage carcinoma of the breast treated by biopsy and radiation therapy with and without adjuvant chemotherapy in an attempt to determine the effect of chemotherapy upon these parameters. Between April 1, l975 and June 1, 1980, 51 patients were treated with radiation therapy and adjuvant chemotherapy (XRT + ACT) and 83 patients with radiotherapy alone (XRT). Cosmetic results deteriorated with time in both groups but to a greater extent in the XRT + ACT group. Comparison of the two treatment groups revealed that complication rates were significantly incresed in the XRT + ACT group. Of the 51 patients in the XRT + ACT group, 21 patients (41%) suffered complications compared to 8 (10%) of the 83 patients in the XRT group. This difference in complication rates resulted primarily from an increased incidence in the XRT + ACT group of wet desquamation in the electron beam portal used to treat the internal mammary lymph nodes and a trend towards a higher incidence of spontaneous nonpathologic rib fractures, myositis and arm edema. The authors' preliminary conclusions are that adjuvant chemotherapy has a negative impact upon cosmesis and complications rates in patients being treated with definitive radiotherapy. However, cosmetic results remain satisfactory and complication rates are maintained at an acceptable level

  4. The CpG island methylator phenotype may confer a survival benefit in patients with stage II or III colorectal carcinomas receiving fluoropyrimidine-based adjuvant chemotherapy

    Colorectal carcinoma (CRC) with CpG island methylator phenotype (CIMP) is recognized as a distinct subgroup of CRC, and CIMP status affects prognosis and response to chemotherapy. Identification of CIMP status in CRC is important for proper patient management. In Eastern countries, however, the clinicopathologic and molecular characteristics and prognosis of CRCs with CIMP are still unclear. A total of 245 patients who underwent their first surgical resection for sporadic CRC were enrolled and CIMP status of the CRCs was determined using the quantitative MethyLight assay. The clinicopathologic and molecular characteristics were reviewed and compared according to CIMP status. In addition, the three-year recurrence-free survival (RFS) of 124 patients with stage II or stage III CRC was analyzed in order to assess the effectiveness of fluoropyrimidine-based adjuvant chemotherapy with respect to CIMP status. CIMP-high CRCs were identified in 34 cases (13.9%), and were significantly associated with proximal tumor location, poorly differentiated carcinoma, mucinous histology, and high frequencies of BRAF mutation, MGMT methylation, and MSI-high compared to CIMP-low/negative carcinomas. For patients with stage II or III CIMP-low/negative CRCs, no significant difference was found in RFS between those undergoing surgery alone and those receiving surgery with fluoropyrimidine-based adjuvant chemotherapy. However, for patients with CIMP-high CRCs, patients undergoing surgery with fluoropyrimidine-based adjuvant chemotherapy (n = 17; three-year RFS: 100%) showed significantly better RFS than patients treated with surgery alone (n = 7; three-year RFS: 71.4%) (P = 0.022). Our results suggest that selected patients with CIMP-high CRC may benefit from fluoropyrimidine-based adjuvant chemotherapy with longer RFS. Further large scale-studies are required to confirm our results

    Biomarkers predicting resistance to particular chemotherapy regimens could play a key role in optimally individualized treatment concepts. PTK7 (protein tyrosine kinase 7) belongs to the receptor tyrosine kinase family involved in several physiological, but also malignant, cell behaviors. Recent studies in acute myeloid leukemia have associated PTK7 expression with resistance to anthracycline therapy. PTK7 mRNA expression in primary tumor tissue (PTT) and corresponding lymph node tissue (LNT) were retrospectively measured in 117 patients with early breast cancer; PTK7 expression was available in 103 PTT and 108 LNT samples. Median age was 60 years (range, 27-87 years). At a median follow-up of 28.5 months, 6 deaths and 16 recurrences had occurred. PTK7 expression correlations with clinicopathological features were computed and PTK7 expression effects on patient outcome were analyzed in three cohorts defined by adjuvant treatment: anthracycline-based treatment, other chemotherapy regimens (including taxane or other substances), or no chemotherapy. Association of PTK7 expression with clinicopathological features was seen only for age in PTT and nodal stage in LNT. High LN PTK7 was associated with poorer disease-free survival (DFS) in the total population (3-year DFS: low [81.7%] versus high [70.4%]; P=0.016) and in patients without adjuvant chemotherapy (3-year DFS: low [91.7%] versus high [22.3%]; P<0.001), but not in patients receiving adjuvant chemotherapy (P=0.552). DFS stratified by PTK7 expression was compared in treatment cohorts: In patients with low LN PTK7 expression, neither chemotherapy cohort showed significantly better survival than the no-chemotherapy cohort. In patients with high LN PTK7 expression, those receiving chemotherapy, including substances other than anthracyclines, but not those receiving only anthracycline-based chemotherapy, showed significantly better DFS than those receiving no chemotherapy (P=0.001). Our results support earlier

  7. Pulmonary function following adjuvant chemotherapy and radiotherapy for breast cancer and the issue of three-dimensional treatment planning

    Background and purpose: The frequency and grade of pulmonary complications following adjuvant radiotherapy for breast cancer are still debated. This study focuses on loss of pulmonary function. Materials and methods: We have measured the reduction of pulmonary function 5 months following radiotherapy in 144 node-positive stage II breast cancer patients by using pulmonary function tests. Results: No deterioration of pulmonary function was detected among the patients who were treated with local radiotherapy. On the contrary, there was a mean increase in diffusion capacity by 7% (P=0.004) following radiotherapy, which most likely was explained by the adjuvant chemotherapy administered prior to the baseline pulmonary function tests. Patients undergoing loco-regional radiotherapy showed a mean reduction in diffusion capacity by 5% (P<0.001) and in vital capacity by 3% (P=0.001). The subset of patients (9%) who were diagnosed with severe pulmonary complications needing cortisone treatment had significantly larger mean paired differences in vital capacity (-0.446 L, -15% (equivalent to 15 years of normal ageing or the loss of 3/4 of a lung lobe)) compared to the patients who were asymptomatic (-0.084 L) (P<0.05). When the effects of potential confounding factors and different radiotherapy techniques were tested on the reduction of pulmonary function by stepwise multiple regression analysis, a significant correlation was found only to loco-regional radiotherapy including the lower internal mammary lymph nodes. Conclusions: We conclude that a clinically important reduction of pulmonary function is seen in the subset of patients who are diagnosed with severe pulmonary complication following loco-regional radiotherapy for breast cancer. The results of this study warrant further studies based on individual lung dose volume histograms. (Copyright (c) 1998 Elsevier Science B.V., Amsterdam. All rights reserved.)

  8. A prospective cohort study of the effects of adjuvant breast cancer chemotherapy on taste function, food liking, appetite and associated nutritional outcomes.

    Anna Boltong

    Full Text Available 'Taste' changes are commonly reported during chemotherapy. It is unclear to what extent this relates to actual changes in taste function or to changes in appetite and food liking and how these changes affect dietary intake and nutritional status.This prospective, repeated measures cohort study recruited participants from three oncology clinics. Women (n = 52 prescribed adjuvant chemotherapy underwent standardised testing of taste perception, appetite and food liking at six time points to measure change from baseline. Associations between taste and hedonic changes and nutritional outcomes were examined.Taste function was significantly reduced early in chemotherapy cycles (p<0.05 but showed recovery by late in the cycle. Ability to correctly identify salty, sour and umami tastants was reduced. Liking of sweet food decreased early and mid-cycle (p<0.01 but not late cycle. Liking of savory food was not significantly affected. Appetite decreased early in the cycle (p<0.001. Reduced taste function was associated with lowest kilojoule intake (r = 0.31; p = 0.008 as was appetite loss with reduced kilojoule (r = 0.34; p = 0.002 and protein intake (r = 0.36; p = 0.001 early in the third chemotherapy cycle. Decreased appetite early in the third and final chemotherapy cycles was associated with a decline in BMI (p = <0.0005 over the study period. Resolution of taste function, food liking and appetite was observed 8 weeks after chemotherapy completion. There was no association between taste change and dry mouth, oral mucositis or nausea.The results reveal, for the first time, the cyclical yet transient effects of adjuvant chemotherapy on taste function and the link between taste and hedonic changes, dietary intake and nutritional outcomes. The results should be used to inform reliable pre-chemotherapy education.

  9. Colonic healing: the effect of irradiation and chemotherapy - an experimental study, resembling adjuvant therapy for colorectal carcinoma

    Adjuvant treatment of colon and rectal carcinoma is of major interest. Irradiation and chemotherapy are modalities used widely. The purpose of this study was to evaluate the effect of preoperative irradiation and postoperative intraperitoneal 5-fluorouracil treatment on colonic healing. In rats preoperative irradiation of the lower abdominal region by 10 + 10 Gy four days apart caused inflammatory reaction in the colon as evaluated by histology and determination of myeloperoxidase activity. The inflammatory reaction reached its peek within a week of the second irradiation. When standard used colonic resections and anastomes were performed within the irradiate part of the colon the anastomotic healing was not affected during the first week after operation as judged by complications and breaking strength. A lower breaking strength and an increase in myeloperoxidase activity two months after operation may indicate late changes within the intestinal wall. Intraperitoneal 5-fluorouracil in rat given immediately after colonic resection and repeated as daily injections caused a weight loss and marked reduction in breaking strength of the anastomosis as well as in the abdominal skin wound. A reduction in 5-fluorouracil concentration did not alter the negative wound healing effect of the chemotherapy. In a group of rats subjected to nutritional depletion, mimicking the weight curve of 5-fluorouracil treated animals, anastomotic breaking strength was not compromised to the same extent as when 5-fluorouracil was given. This indicated a direct toxic effect rather than an effect of reduced food intake caused by 5-FU treatment. Collagen synthesis and the formation of new tissue in the wound gap was reduced in 5-fluorouracil treated animals compared to controls as judged by in vivo incorporation of 3H-proline in the anastomotic segment and determination of anastomotic breaking strength after removal of sutures. 108 refs

    1999-05-01

    The purpose of the present paper was to evaluate treatment outcome after conservative breast surgery or mastectomy followed by simultaneous adjuvant radiotherapy and cyclophosphamide, methotrexate and fluorouracil (CMF) therapy. Two hundred and sixty eight (268) patients were treated at two Australian and two New Zealand centres between 1981 and July 1995. One hundred and sixty-nine patients underwent conservation surgery and 99 had mastectomies. Median follow-up was 53 months. Conventionally fractionated radiation was delivered simultaneously during the first two cycles of CMF, avoiding radiation on the Fridays that the intravenous components of CMF were delivered. In conservatively treated patients, 5-year actuarial rates of any recurrence, distant recurrence and overall survival were 34.5 {+-} 5.2%, 25.4 {+-} 4.5% and 75.5 {+-} 4.8%, respectively. Crude incidence of local relapse at 4 years was 6.3% and at regional/distant sites was 26.3%. Highest grades of granulocyte toxicity (< 0.5 x 10{sup 9}/L), moist desquamation, radiation pneumonitis and persistent breast oedema were recorded in 10.7, 8.5, 8.9 and 17.2%, respectively. In patients treated by mastectomy, 5-year actuarial rates of any recurrence, distant recurrence and overall survival were 59.7 {+-} 7.3%, 56.7 {+-} 7.4% and 50.1 {+-} 7%. The crude incidence of local relapse at 4 years was 5.6% and at regional/distant sites it was 45.7%. The issue of appropriate timing of adjuvant therapies has become particularly important with the increasing acknowledgement of the value of anthracycline-based regimens. For women in lower risk categories (e.g. 1-3 nodes positive or node negative), CMF may offer a potentially better therapy, particularly where breast-conserving surgical techniques have been used. In such cases CMF allows the simultaneous delivery of radiotherapy with the result of optimum local control, without compromise or regional or systemic relapse rates.

    Full Text Available Neoadjuvant chemotherapy (NACT in breast cancer has undergone continuous evolution over the last few decades to establish its role in the combined modality management of these tumors. The process of evolution is still far from over. Many questions are still lurking in the minds of oncologists treating breast cancer. This review analyzes the evidence from metaanlyses, major multiinstitutional prospective trials, retrospective institutional series and systematic reviews in breast cancer to determine the current standards and controversies in NACT. The most effective drugs, their advantages, issues and controversies in delivery as well as the criteria for response are reviewed. A summary of evidence-based consensus is presented and unresolved aspects are discussed.

  12. Concomitant chemotherapy and radiotherapy in the adjuvant treatment of breast cancer

    The conventional treatment of localized breast cancer involves the use of both systemic therapy and loco-regional radiation after surgery. The ideal sequence of these two treatments is still undefined. This paper focus on our experience of concomitant chemotherapy (CT) and radiotherapy (RT), and discusses information from the literature about this issue. Between Jan,1989 and Jan, 1999 a retrospective analysis of 103 patients with ductal carcinoma of the breast who received concomitant CT with cyclophosphamide, methotrexate and 5 flurouracil (CMF) and RT was made. Radiation did not included mammary chain or axilla and total dose was of 50 Gy. End points were tolerance and oxicity leading changes to doses. Mean age was 44y; median follow up time of 33 mo; 62 patients had breast conserving surgery and 41 had mastectomy. All patients received both treatments without a break or dose modification. There was no change or interruption of RT. Ten out of 103 patients had the prescribed dose of CT decreased of 10%-20%. There was no evident changes in cosmetic results. Most of the knowledge regarding the delay of CT or RT comes from retrospective studies, and results are conflicting. It is well accepted that high risk patients need both CT and RT. However, there are data suggesting that giving RT first and CT after may increase the rate of distant metastases. There are also studies showing worse impact in the local control with the delay of radiotherapy. The use of concomitant chemotherapy and radiotherapy has apparent advantages, but no randomized trial has addressed this issue yet. Our experience has shown that is possible to give concomitant CT with CMF and RT without irradiation of IMC and axilla without major changes in scheduling or dose of both therapies. (author)

  13. Clinical implications of thymidylate synthetase, dihydropyrimidine dehydrogenase and orotate phosphoribosyl transferase activity levels in colorectal carcinoma following radical resection and administration of adjuvant 5-FU chemotherapy

    A number of studies have investigated whether the activity levels of enzymes involved in 5-fluorouracil (5-FU) metabolism are prognostic factors for survival in patients with colorectal carcinoma. Most reports have examined thymidylate synthetase (TS) and dihydropyrimidine dehydrogenase (DPD) in unresectable or metastatic cases, therefore it is unclear whether the activity of these enzymes is of prognostic value in colorectal cancer patients treated with radical resection and adjuvant chemotherapy with 5-FU. This study examined fresh frozen specimens of colorectal carcinoma from 40 patients who had undergone curative operation and were orally administered adjuvant tegafur/uracil (UFT) chemotherapy. TS, DPD and orotate phosphoribosyl transferase (OPRT) activities were assayed in cancer tissue and adjacent normal tissue and their association with clinicopathological variables was investigated. In addition, the relationships between TS, DPD and OPRT activities and patient survival were examined to determine whether any of these enzymes could be useful prognostic factors. While there was no clear relationship between pathological findings and TS or DPD activity, OPRT activity was significantly lower in tumors with lymph node metastasis than in tumors lacking lymph node metastasis. Postoperative survival was significantly better in the groups with low TS activity and/or high OPRT activity. TS and OPRT activity levels in tumor tissue may be important prognostic factors for survival in Dukes' B and C colorectal carcinoma with radical resection and adjuvant chemotherapy with UFT

  14. Plasmacytoid variant of bladder cancer defines patients with poor prognosis if treated with cystectomy and adjuvant cisplatin-based chemotherapy

    Since the definition of different histologic subtypes of urothelial carcinomas by the World Health Organization (WHO) 2004 classification, description of molecular features and clinical behavior of these variants has gained more attention. We reviewed 205 tumor samples of patients with locally advanced bladder cancer mainly treated within the randomized AUO-AB05/95 trial with radical cystectomy and adjuvant cisplatin-based chemotherapy for histologic subtypes. 178 UC, 18 plasmacytoid (PUC) and 9 micropapillary (MPC) carcinomas of the bladder were identified. Kaplan Meier analysis and backward multivariate Cox’s proportional hazards regression analysis were performed to compare overall survival between the three histologic subtypes. Patients suffering from PUC have the worst clinical outcome regarding overall survival compared to conventional UC and MPC of the bladder that in turn seem have to best clinical outcome (27.4 months, 62.6 months, and 64.2 months, respectively; p=0.013 by Kaplan Meier analysis). Backward multivariate Cox´s proportional hazards regression analysis (adjusted to relevant clinicopathological parameters) showed a hazard ratio of 3.2 (p=0.045) for PUC in contrast to patients suffering from MPC. Histopathological diagnosis of rare variants of urothelial carcinoma can identify patients with poor prognosis

    Purpose: Analysis of the feasibility and results of adjuvant chemotherapy followed by conformal chemoradiotherapy after surgery for gastric carcinoma. Patients and methods Twenty-six patients (R0 or R1) were treated postoperatively by three cycles of 5-fluorouracil (5-FU) and cisplatin, followed by a concomitant association of LV5FU2 chemotherapy with a conformal radiotherapy of 45 Gy. Results: The tumor was classified pT3-T4 in 77% of the patients and 92.5% had a nodal involvement (pN1: 54%; pN2: 31%). Feasibility (1) Adjuvant chemotherapy: nausea/vomiting grade II/III: 12 patients (48%); neutropenia grade III/IV: two patients; completed in all patients, except one. (2) Chemoradiotherapy: nausea/vomiting grade II/III: 10 patients; diarrhea grade II/3: two patients; oesophagitis grade II/III: two patients; myocardial infarction/pulmonary embolism: two patients. All patients except one received the planned dose of 45 Gy. Radiotherapy was interrupted in six cases, with a median duration of 14 days. Survival: with a median follow-up of 30 months, 65% of the patients were alive without disease; median survival was 32 months. Conclusion: This postoperative schedule was judged feasible. It allowed the deliverance of a more intensified chemotherapy than the classical schedule. Its clinical benefit must be evaluated in a phase III trial. (authors)

  19. Pathologic tumor size and lymph node status predict for different rates of locoregional recurrence after mastectomy for breast cancer patients treated with neoadjuvant versus adjuvant chemotherapy

    Purpose: To compare the pathologic factors associated with postmastectomy locoregional recurrence (LRR) in breast cancer patients not receiving radiation who were treated with neoadjuvant chemotherapy (NEO) vs. adjuvant chemotherapy (ADJ). Methods and Materials: We retrospectively analyzed the rates of LRR of subsets of women treated in prospective trials who underwent mastectomy and received chemotherapy but not radiation. These trials were designed to answer chemotherapy questions. There were 150 patients in the NEO group and 1031 patients in the ADJ group. In the NEO group, 55% had clinical Stage IIIA or higher vs. 9% in the ADJ group (p5 cm (46% vs. 28%, p=0.028). The risk of LRR by the number of +LNs was similar in the NEO and ADJ groups, except for the subset of patients with ≥4 +LNs (53% vs. 23%, p5 cm, or clinical Stage IIIA or greater disease, regardless of whether they receive neoadjuvant or postoperative chemotherapy. The information assessing LRR rates in patients with clinical Stage II disease who receive neoadjuvant chemotherapy, particularly if 1-3 lymph nodes remain pathologically involved, is insufficient to determine whether these patients should receive radiotherapy

  20. Is drug-induced toxicity a good predictor of response to neo-adjuvant chemotherapy in patients with breast cancer? -A prospective clinical study

    Neo-adjuvant chemotherapy is an integral part of multi-modality approach in the management of locally advanced breast cancer and it is vital to predict the response in order to tailor the regime for a patient. The common final pathway in the tumor cell death is believed to be apoptosis or programmed cell death and chemotherapeutic drugs like other DNA-damaging agents act on rapidly multiplying cells including both the tumor and the normal cells by following the same common final pathway. This could account for both the toxic effects and the response. Absence or decreased apoptosis has been found to be associated with chemo resistance. The change in expression of apoptotic markers (Bcl-2 and Bax proteins) brought about by various chemotherapeutic regimens is being used to identify drug resistance in the tumor cells. A prospective clinical study was conducted to assess whether chemotherapy induced toxic effects could serve as reliable predictors of apoptosis or response to neo-adjuvant chemotherapy in patients with locally advanced breast cancer. 50 cases of locally advanced breast cancer after complete routine and metastatic work up were subjected to trucut biopsy and the tissue evaluated immunohistochemically for apoptotic markers (bcl-2/bax ratio). Three cycles of Neoadjuvant Chemotherapy using FAC regime (5-fluorouracil, adriamycin, cyclophosphamide) were given at three weekly intervals and patients assessed for clinical response as well as toxicity after each cycle. Modified radical mastectomy was performed in all patients three weeks after the last cycle and the specimen were re-evaluated for any change in the bcl-2/bax ratio. The clinical response, immunohistochemical response and the drug-induced toxicity were correlated and compared. Descriptive studies were performed with SPSS version 10 and the significance of response was assessed using paired t-test. Significance of correlation between various variables was assessed using chi-square test and coefficient

  2. Study protocol of the B-CAST study: a multicenter, prospective cohort study investigating the tumor biomarkers in adjuvant chemotherapy for stage III colon cancer

    Adjuvant chemotherapy for stage III colon cancer is internationally accepted as standard treatment with established efficacy. Several oral fluorouracil (5-FU) derivatives with different properties are available in Japan, but which drug is the most appropriate for each patient has not been established. Although efficacy prediction of 5-FU derivatives using expression of 5-FU activation/metabolism enzymes in tumors has been studied, it has not been clinically applied. The B-CAST study is a multicenter, prospective cohort study aimed to identify the patients who benefit from adjuvant chemotherapy with each 5-FU regimen, through evaluating the relationship between tumor biomarker expression and treatment outcome. The frozen tumor specimens of patients with stage III colon cancer who receives postoperative adjuvant chemotherapy are examined. Protein expression of thymidine phosphorylase (TP), dihydropyrimidine dehydrogenase (DPD), epidermal growth factor receptor (EGFR), and vascular endothelial growth factor (VEGF) are evaluated using enzyme-linked immunosorbent assay (ELISA). mRNA expression of TP, DPD, thymidylate synthase (TS) and orotate phosphoribosyl transferase (OPRT) are evaluated using reverse transcription polymerase chain reaction (RT-PCR). The patients’ clinical data reviewed are as follow: demographic and pathological characteristics, regimen, drug doses and treatment duration of adjuvant therapy, types and severity of adverse events, disease free survival, relapse free survival and overall survival. Then, relationships among the protein/mRNA expression, clinicopathological characteristics and the treatment outcomes are analyzed for each 5-FU derivative. A total of 2,128 patients from the 217 institutions were enrolled between April 2009 and March 2012. The B-CAST study demonstrated that large-scale, multicenter translational research using frozen samples was feasible when the sample shipment and Web-based data collection were well organized.

Recent studies in acute myeloid leukemia have associated PTK7 expression with resistance to anthracycline therapy. PTK7 mRNA expression in primary tumor tissue (PTT and corresponding lymph node tissue (LNT were retrospectively measured in 117 patients with early breast cancer; PTK7 expression was available in 103 PTT and 108 LNT samples. Median age was 60 years (range, 27–87 years. At a median follow-up of 28.5 months, 6 deaths and 16 recurrences had occurred. PTK7 expression correlations with clinicopathological features were computed and PTK7 expression effects on patient outcome were analyzed in three cohorts defined by adjuvant treatment: anthracycline-based treatment, other chemotherapy regimens (including taxane or other substances, or no chemotherapy. Association of PTK7 expression with clinicopathological features was seen only for age in PTT and nodal stage in LNT. High LN PTK7 was associated with poorer disease-free survival (DFS in the total population (3-year

  4. Intensity-modulated whole abdomen irradiation following adjuvant carboplatin/taxane chemotherapy for FIGO stage III ovarian cancer. Four-year outcomes

    A prospective study to assess toxicity and survival outcomes after intensity-modulated whole-abdominal irradiation (IM-WAI) following surgery and adjuvant intravenous carboplatin/taxane chemotherapy in advanced FIGO stage III ovarian cancer. Between 2006 and 2009, 16 patients with optimally resected FIGO stage III ovarian cancer, who had received six cycles of adjuvant carboplatin/taxane chemotherapy were treated with consolidation IM-WAI. Radiotherapy was delivered to a total dose of 30 Gy in 1.5-Gy fractions, using step-and-shoot (n = 3) or helical tomotherapy (n = 13). The first 10 patients were treated within a phase I trial; the following patients received the same treatment modality. The target volume included the entire peritoneal cavity, the diaphragm, the liver capsule, and the pelvic and para-aortic node regions. Organs at risk were kidneys, liver, heart, and bone marrow. Median follow-up was 44 months (range 19.2-67.2 months). No grade 4 toxicities occurred during IM-WAI. Common Toxicity Criteria for Adverse Events (CTCAE) grade 3 toxicities were: diarrhea (25 %), leucopenia (19 %), nausea/vomiting (6 %), and thrombocytopenia (6 %). No toxicity-related treatment break was necessary. Small bowel obstruction occurred in a total of 6 patients: in 3 cases (19 %) due to postsurgical adhesions and in 3 cases due to local tumor recurrence (19 %). Median recurrence-free survival (RFS) was 27.6 months (95 % confidence interval, CI = 24-44 months) and median overall survival (OS) was 42.1 months (95 %CI = 17-68 months). The peritoneal cavity was the most frequent site of initial failure. Consolidation IM-WAI following surgery and adjuvant chemotherapy is feasible and can be performed with manageable acute and late toxicity. The favorable RFS outcome is promising and justifies further clinical trials. (orig.)

  6. CyberKnifeR and neo-adjuvant chemotherapy for locally advanced breast tumours: results of the dose escalation phase I

    CyberKnife allows the performance of stereotactic radiotherapy of thorax tumours with accuracy and with a real time target tracking system. The authors aimed at demonstrating the interest of this system for the treatment of breast cancers. They report a phase I study of dose escalation. A neo-adjuvant based chemotherapy is associated with the irradiation. Breast surgery is performed six to eight weeks after the sixth chemotherapy session cycle. The aim was to determine the maximum tolerated dose for the hypo-fractionated radiotherapy. Cutaneous toxicity is the limiting factor. 25 patients have been treated with different dose levels (from 18,5 to 31,5 Gy). Results are promising and must be confirmed, notably through a randomized multicentre phase II study. Short communication

    Background Dihydropyrimidine dehydrogenase (DPD),a key enzyme involved in the catabolism of 5-fluorouracil (5-FU),is the attractive candidate for pharmacogenetic research on efficacies and toxicities of 5-FU.The aim of this study is to explore the association between polymorphisms of dihydropyrimidine dehydrogenase gene (DPYD) and clinical outcomes of gastric cancer patients treated with fluorouracil-based adjuvant chemotherapy in the Chinese population.Methods Three hundred and sixty-two patients with gastric cancer in the Chinese population were treated with fluorouracil-based adjuvant chemotherapy.The single nucleotide polymorphic genotypes of DPYD were determined by matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF-MS) using DNA samples isolated from peripheral blood collected before treatment.Results The average response rate for chemotherapy was 46.7%.A significantly different distribution of the rs1801159 (x2=8.76,P=0.012) genotypes was observed.Homozygous genotype rs1801159A/A was over-represented in responsive patients.Conversely,carriers of the rs1801159A/G genotype were prevalent in non-responsive patients.In the haplotype association analysis,there was significant difference in global haplotype distribution between the groups (x2=3.96,P=0.0465).Conclusions These results suggest that polymorphisms of rs1801159 in DPYD may be used as valuable predictors of the response to fluorouracil-based chemotherapy for gastric cancer patients in the Chinese population.Well-designed,comprehensive,and prospective studies on determining these polymorphisms of DPYD as predictive markers for gastric cancer in response to fluorouracil-based therapies are warranted.

  8. Phase II/III multicentre randomised controlled trial evaluating a strategy of primary surgery and adjuvant chemotherapy versus peri-operative chemotherapy for resectable gastric signet ring cell adenocarcinomas – PRODIGE 19 – FFCD1103 – ADCI002

    A dramatic increase in the incidence of the diffuse form of gastric adenocarcinomas and particularly signet ring cell carcinomas has been observed in Western countries. Evidence is accruing that signet ring cell carcinomas may have inherent chemo resistance leaving many clinicians unsure of the benefits of delaying surgery to pursue a neoadjuvant approach. PRODIGE-19-FFCD1103-ADCI002 is a prospective multicentre controlled randomised phase II/III trial comparing current standard of care of perioperative chemotherapy (2x3 cycles of Epirubicin, cisplatin, 5-fluorouracil) with a strategy of primary surgery followed by adjuvant chemotherapy (6 cycles of Epirubicin, cisplatin, 5-fluorouracil) in patients with a stage IB-III gastric signet ring cell tumour. The principal objective of the phase II study (84 patients) is to determine if the experimental arm (primary surgery followed by adjuvant chemotherapy) has sufficient interest in terms of percentage of living patients at 24 months to be evaluated in a phase III trial. If 7 or less patients in the experimental arm are alive at 24 months, phase III will not be initiated. The primary objective of phase III (230 additional patients) is to demonstrate superiority of the experimental arm in terms of overall survival. Secondary endpoints include overall survival at 36 months, disease free survival at 24 and 36 months, R0 resection rates, treatment tolerance, postoperative mortality and morbidity evaluated by Clavien-Dindo severity index, the prognostic impact of positive peritoneal cytology and the assessment of quality of life. An ancillary study will assess the emotional and cognitive impact of surgery and perioperative chemotherapy for both the patient and their partner. As inherent chemo resistance of signet ring cell tumours and delay in definitive surgery may favour tumour progression we hypothesise that a policy of primary surgery followed by adjuvant chemotherapy will improve overall survival compared to a standard

    International audience OBJECTIVES: Adjuvant chemotherapy with vinorelbine plus cisplatin (VC) improves survival in resected non-small-cell lung cancer (NSCLC), but has negative impact on quality of life (QoL). In advanced NSCLC, gemcitabine plus cisplatin (GC) and docetaxel plus cisplatin (DC) exhibit comparable efficacy, with possibly superior QoL compared to VC. This trial investigated these regimens in the adjuvant setting. METHODS: Patients with Stage IB to III NSCLC were eligible foll...

    We investigated the correlation of ataxia-telangiectasia-mutated (ATM) protein expression with clinicopathological features and prognosis in patients with breast cancer. ATM expression was determined by immunohistochemistry in 420 surgically resected breast tumors. ATM loss was observed in 126/407 evaluable cases (31.0 %), and was significantly associated with larger tumor size, lymph node metastasis, higher tumor grade, and ER- and/or PR-negative status. ATM loss was also associated with significantly lower disease-free survival rates than those in patients with intact ATM (5-year disease-free survival rate 81.2 vs. 90.7 %, p = 0.015). In multivariate analysis, ATM loss combined with abnormal p53 expression was an independent predictor of shorter disease-free survival [hazard ratio (HR) 3.48; 95 % confidence interval (CI), 1.48-8.17, p = 0.004]. A tendency towards a poorer prognosis was observed for tumoral ATM loss alone, although statistical significance was not reached (HR 1.74; 95 % CI 0.95-3.20; p = 0.075). In subgroup analysis, ATM loss was associated with shorter disease-free survival in patients who did not receive adjuvant anthracycline chemotherapy (5-year disease-free survival rate 92.7 % in intact ATM group vs. 68.1 % in ATM loss group, p = 0.002), but this poor prognosis was overcome in patients who did (5-year disease-free survival rate 89.8 vs. 84.4 %, p = 0.243), suggesting more benefit from anthracycline-based chemotherapy. Tumors with loss of ATM expression have a poor prognosis and their prognoses are dependent on the use of adjuvant anthracycline. ATM loss might be a practical tool for predicting benefits from anthracycline-based adjuvant therapy. PMID:27329169

    The purpose of this study was to conduct an exploratory analysis of the START examining the effects of resistance exercise training (RET) and aerobic exercise training (AET) on sarcopenia, dynapenia, and associated quality of life (QoL) changes in breast cancer (BC) patients receiving adjuvant chemotherapy. Participants were randomized to usual care (UC) (n = 70), AET (n = 64), or RET (n = 66) for the duration of chemotherapy. Measures of sarcopenia [skeletal muscle index (SMI)] and dynapenia [upper extremity (UE) and lower extremity (LE) muscle dysfunction (MD)] were normalized relative to age-/sex-based clinical cut-points. QoL was assessed by the Functional Assessment of Cancer Therapy-Anemia (FACT-An) scales. At baseline, 25.5 % of BC patients were sarcopenic and 54.5 % were dynapenic with both conditions associated with poorer QoL. ANCOVAs showed significant differences favoring RET over UC for SMI (0.32 kg/m(2); p = 0.017), UE-MD (0.12 kg/kg; p < 0.001), and LE-MD (0.27 kg/kg; p < 0.001). Chi-square analyses revealed significant effects of RET, compared to UC/AET combined, on reversing sarcopenia (p = 0.039) and dynapenia (p = 0.019). The reversal of sarcopenia was associated with clinically relevant improvements in the FACT-An (11.7 points [95 % confidence interval (CI) -4.2 to 27.6]), the Trial Outcome Index-Anemia (10.0 points [95 % CI -4.0 to 24.1]), and fatigue (5.3 points [95 % CI -1.5 to 12.1]). Early-stage BC patients initiating adjuvant chemotherapy have higher than expected rates of sarcopenia and dynapenia which are associated with poorer QoL. RET during adjuvant chemotherapy resulted in the reversal of both sarcopenia and dynapenia; however, only the reversal of sarcopenia was associated with clinically meaningful improvements in QoL.

  13. Randomized Trial of Postoperative Adjuvant Therapy in Stage II and III Rectal Cancer to Define the Optimal Sequence of Chemotherapy and Radiotherapy: 10-Year Follow-Up

    Purpose: To determine the optimal sequence of postoperative adjuvant chemotherapy and radiotherapy in patients with Stage II or III rectal cancer. Methods and Materials: A total of 308 patients were randomized to early (n = 155) or late (n = 153) radiotherapy (RT). Treatment included eight cycles of chemotherapy, consisting of fluorouracil 375 mg/m2/day and leucovorin 20 mg/m2/day, at 4-week intervals, and pelvic radiotherapy of 45 Gy in 25 fractions. Radiotherapy started on Day 1 of the first chemotherapy cycle in the early RT arm and on Day 1 of the third chemotherapy cycle in the late RT arm. Results: At a median follow-up of 121 months for surviving patients, disease-free survival (DFS) at 10 years was not statistically significantly different between the early and late RT arms (71% vs. 63%; p = 0.162). A total of 36 patients (26.7%) in the early RT arm and 49 (35.3%) in the late RT arm experienced recurrence (p = 0.151). Overall survival did not differ significantly between the two treatment groups. However, in patients who underwent abdominoperineal resection, the DFS rate at 10 years was significantly greater in the early RT arm than in the late RT arm (63% vs. 40%; p = 0.043). Conclusions: After the long-term follow-up duration, this study failed to show a statistically significant DFS advantage for early radiotherapy with concurrent chemotherapy after resection of Stage II and III rectal cancer. Our results, however, suggest that if neoadjuvant chemoradiation is not given before surgery, then early postoperative chemoradiation should be considered for patients requiring an abdominoperineal resection.

  14. Correlation of FDG-PET measurements with morphometric tumor response after induction chemotherapy and adjuvant radiotherapy in stage III non-small cell lung cancer (NSCLC)

    Full text: Docetaxel (D) and carboplatin (C) combination chemotherapy (DC) has shown high response rates in advanced NSCLC. Histologic tumor response after chemotherapy or combined modality induction is strongly associated with systemic tumor control and potentially cure. Metabolic tumor response assessed by FDG-PET after induction chemotherapy with etoposide, ifosfamide and cisplatin (VIP) has been shown to be predictive of outcome in NSCLC. Finally, erythropoietin (EPO) may prevent the decrease in hemoglobin levels that was seen in a previous study of DC (median drop 2.7 g/dl) and thus may enhance treatment efficacy. The aim of the present study was to correlate FDG-PET studies with histomorphometric findings after DC induction chemotherapy plus Epo. 33 patients (pts) with NSCLC stage IIIA (7 pts) or IIIB (24 pts) were enrolled and received treatment with D 100 mg/m2 dl and C AUC 7.5 d2 q21 days for 4 cycles. Epo was given at 10,000 IU s.c. three times a week. All pts received adjuvant radiotherapy. Of 33 enrolled patients, 22 were evaluable for response by CT imaging. 14/22 pts (64 %) achieved PR. Of the 22 responders, 20 were evaluable for repeated FDG-PET studies. 13/20 pts had a decrease of standardized uptake values (SUV) and of the metabolic tumor index (MTI) by >50 %, 9/20 had SUV <2.5 (CR). Seven of these 9 pts underwent tumor resection, and specimens were subjected to morphometric analysis. In 7/7 cases, no vital tumor cells were detected in the specimens. In contrast to our previous study, hemoglobin levels increased by a median of 0.3 g/dl. Morphometric tumor response after induction chemotherapy correlates strongly with metabolic remission by FDG-PET. FDG-PET appears to be a useful non-invasive diagnostic tool to predict pathologic response and potentially long-term outcome in stage III NSCLC. (author)

  15. Neo-adjuvant chemotherapy followed by surgery and chemotherapy or by surgery and chemoradiotherapy for patients with resectable gastric cancer (CRITICS)

    Radical surgery is the cornerstone in the treatment of resectable gastric cancer. The Intergroup 0116 and MAGIC trials have shown benefit of postoperative chemoradiation and perioperative chemotherapy, respectively. Since these trials cannot be compared directly, both regimens are evaluated prospectively in the CRITICS trial. This study aims to obtain an improved overall survival for patients treated with preoperative chemotherapy and surgery by incorporating radiotherapy concurrently with chemotherapy postoperatively. In this phase III multicentre study, patients with resectable gastric cancer are treated with three cycles of preoperative ECC (epirubicin, cisplatin and capecitabine), followed by surgery with adequate lymph node dissection, and then either another three cycles of ECC or concurrent chemoradiation (45 Gy, cisplatin and capecitabine). Surgical, pathological, and radiotherapeutic quality control is performed. The primary endpoint is overall survival, secondary endpoints are disease-free survival (DFS), toxicity, health-related quality of life (HRQL), prediction of response, and recurrence risk assessed by genomic and expression profiling. Accrual for the CRITICS trial is from the Netherlands, Sweden, and Denmark, and more countries are invited to participate. Results of this study will demonstrate whether the combination of preoperative chemotherapy and postoperative chemoradiotherapy will improve the clinical outcome of the current European standard of perioperative chemotherapy, and will therefore play a key role in the future management of patients with resectable gastric cancer. clinicaltrials.gov http://www.clinicaltrials.gov/ct2/show/NCT00407186

    2012-01-01

    Full Text Available Radiation recall phenomenon is an inflammatory process occurring at sites of previous radiation subsequent to administration of pharmacologic agents. The most common chemotherapeutic agents implicated with radiation recall phenomenon are anthracyclines and taxanes. Skin is the most common site for radiation recall. About 63% of the radiation recall events are reported to manifest as dermatitis. This finding differs from radiation recall due to Gemcitabine, in which approximately 70% cases manifested as inflammation of internal organs or tissues and 30% manifested as dermatitis. Here, we report a case of post-operative peri-ampullary carcinoma who developed radiation recall dermatitis during adjuvant chemotherapy with inj. Gemcitabine and inj. Carboplatin after concurrent chemoradiation with capecitabine.

    2011-02-01

    Full Text Available Abstract Background Sentinel lymph node biopsy (SLNB is now considered a standard of care in early breast cancers with N0 axillae; however, its role in locally advanced breast cancer (LABC after neo-adjuvant chemotherapy (NACT is still being debated. The present study assessed the feasibility, efficacy and accuracy of sentinel lymph node biopsy (SLNB using "dye alone" (methylene blue method in patients with LABC following NACT. Materials and methods Thirty, biopsy proven cases of LABC that had received three cycles of neo-adjuvant chemotherapy (cyclophosphamide, adriamycin, 5-fluorouracil were subjected to SLNB (using methylene blue dye followed by complete axillary lymph node dissection (levels I-III. The sentinel node(s was/were and the axilla were individually assessed histologically. The SLN accuracy parameters were calculated employing standard definitions. The SLN identification rate in the present study was 100%. The sensitivity of SLNB was 86.6% while the accuracy was 93.3%, which were comparable with other studies done using dual lymphatic mapping method. The SLN was found at level I in all cases and no untoward reaction to methylene blue dye was observed. Conclusions This study confirms that SLNB using methylene blue dye as a sole mapping agent is reasonably safe and almost as accurate as dual agent mapping method. It is likely that in the near future, SLNB may become the standard of care and provide a less morbid alternative to routine axillary lymph node dissection even in patients with LABC that have received NACT.

  20. Trial on Refinement of Early stage non-small cell lung cancer. Adjuvant chemotherapy with pemetrexed and cisplatin versus vinorelbine and cisplatin: The TREAT protocol

    Adjuvant chemotherapy has been proven to be beneficial for patients with early stage non-small cell lung cancer. However, toxicity and insufficient dose delivery have been critical issues with the chemotherapy used. Doublet regimens with pemetrexed, a multi-target folate inhibitor, and platin show clear activity in non-small cell lung cancer and are well tolerated with low toxicity rates and excellent delivery. In this prospective, multi-center, open label randomized phase II study, patients with pathologically confirmed non-small cell lung cancer, stage IB, IIA, IIB, T3N1 will be randomized after complete tumor resection either to 4 cycles of the standard adjuvant vinorelbine and cisplatin regimen from the published phase III data, or to 4 cycles of pemetrexed 500 mg/m2 d1 and cisplatin 75 mg/m2 d1, q 3 weeks. Primary objective is to compare the clinical feasibility of these cisplatin doublets defined as non-occurrence of grade 4 neutropenia and/or thrombocytopenia > 7 days or bleeding, grade 3/4 febrile neutropenia and/or infection, grade 3/4 non-hematological toxicity, non-acceptance leading to premature withdrawal and no cancer or therapy related death. Secondary parameters are efficacy (time to relapse, overall survival) and drug delivery. Parameters of safety are hematologic and non-hematologic toxicity of both arms. The TREAT trial was designed to evaluate the clinical feasibility, i.e. rate of patients without dose limiting toxicities or premature treatment withdrawal or death of the combination of cisplatin and pemetrexed as well as the published phase III regimen of cisplatin and vinorelbine. Hypothesis of the study is that reduced toxicities might improve the feasibility of drug delivery, compliance and the convenience of treatment for the patient and perhaps survival.

    2014-01-01

    Purpose To characterize upregulation of hypoxia-inducible factor (HIF)-1α after radiofrequency (RF) ablation and the influence of an adjuvant HIF-1α inhibitor (bortezomib) and nanodrugs on modulating RF ablation–upregulated hypoxic pathways. Materials and Methods Fisher 344 rats (n = 68) were used. First, RF ablation–induced periablational HIF-1α expression was evaluated in normal liver or subcutaneous R3230 tumors (14–16 mm). Next, the effect of varying RF ablation thermal dose (varying tip temperature 50°C–90°C for 2–20 minutes) on HIF-1α expression was studied in R3230 tumors. Third, RF ablation was performed in R3230 tumors without or with an adjuvant HIF-1α inhibitor, bortezomib (single intraperitoneal dose 0.1 mg/kg). Finally, the combination RF ablation and intravenous liposomal chemotherapeutics with known increases in periablational cellular cytotoxicity (doxorubicin, paclitaxel, and quercetin) was assessed for effect on periablational HIF-1α. Outcome measures included immunohistochemistry of HIF-1α and heat shock protein 70 (marker of nonlethal thermal injury). Results RF ablation increased periablational HIF-1α in both normal liver and R3230 tumor, peaking at 24–72 hours. Tumor RF ablation had similar HIF-1α rim thickness but significantly greater percent cell positivity compared with hepatic RF ablation (P nanodrugs suppressed RF ablation–induced HIF-1α (ie, rim thickness and cell positivity; P < .02 for all comparisons), with liposomal doxorubicin suppressing HIF-1α the most (P < .03). Conclusions RF ablation upregulates HIF-1α in normal liver and tumor in a temperature-independent manner. This progrowth, hypoxia pathway can be successfully suppressed with an adjuvant HIF-1α-specific inhibitor, bortezomib, or non–HIF-1α-specific liposomal chemotherapy. PMID:25439675

    A prospective study to assess toxicity and survival outcomes after intensity-modulated whole-abdominal irradiation (IM-WAI) following surgery and adjuvant intravenous carboplatin/taxane chemotherapy in advanced FIGO stage III ovarian cancer. Between 2006 and 2009, 16 patients with optimally resected FIGO stage III ovarian cancer, who had received six cycles of adjuvant carboplatin/taxane chemotherapy were treated with consolidation IM-WAI. Radiotherapy was delivered to a total dose of 30 Gy in 1.5-Gy fractions, using step-and-shoot (n = 3) or helical tomotherapy (n = 13). The first 10 patients were treated within a phase I trial; the following patients received the same treatment modality. The target volume included the entire peritoneal cavity, the diaphragm, the liver capsule, and the pelvic and para-aortic node regions. Organs at risk were kidneys, liver, heart, and bone marrow. Median follow-up was 44 months (range 19.2-67.2 months). No grade 4 toxicities occurred during IM-WAI. Common Toxicity Criteria for Adverse Events (CTCAE) grade 3 toxicities were: diarrhea (25 %), leucopenia (19 %), nausea/vomiting (6 %), and thrombocytopenia (6 %). No toxicity-related treatment break was necessary. Small bowel obstruction occurred in a total of 6 patients: in 3 cases (19 %) due to postsurgical adhesions and in 3 cases due to local tumor recurrence (19 %). Median recurrence-free survival (RFS) was 27.6 months (95 % confidence interval, CI = 24-44 months) and median overall survival (OS) was 42.1 months (95 %CI = 17-68 months). The peritoneal cavity was the most frequent site of initial failure. Consolidation IM-WAI following surgery and adjuvant chemotherapy is feasible and can be performed with manageable acute and late toxicity. The favorable RFS outcome is promising and justifies further clinical trials. (orig.)

    2016-04-01

    Chemotherapy-induced amenorrhea (CIA) is a side effect that occurs in patients with breast cancer (BC) as a result of chemotherapy. These patients require special treatments to avoid infertility and menopause. However, the factors controlling CIA, resumption of menstruation (RM), and persistence of menstruation after chemotherapy are unknown. The long-term prognosis for premenopausal patients with BC and the prognostic factors associated with CIA and RM are subject to debate. We performed a retrospective study by reviewing the medical records of 249 patients with BC (stage I to stage III) who were treated with cytotoxic chemotherapy. The median patient age was 43 (range, 26-55 years) and the median duration of follow-up was 64 months (range, 28-100 months). The medical records indicated that 219 patients (88.0%) scored as positive for the hormone receptor (HR); the majority of these patients completed chemotherapy and then received additional therapy of tamoxifen. Our analyses revealed that 88.0% (n = 219) of patients experienced CIA, and the percentage of RM during follow-up was 48.6% (n = 121). A total of 30 patients (12.0%) did not experience CIA. Disease-free survival (DFS) was affected by several factors, including tumour size ≥2 cm, node positivity, HR negative status, and body mass index ≥23 kg/m. Multivariate analysis indicated that tumour size ≥2 cm remained as a significant factor for DFS (hazard ratio = 3.3, P = 0.034). In summary, this study finds that the majority of premenopausal patients with BC (stage I to stage III) who receive chemotherapy experience CIA and subsequent RM. Although tumour size ≥2 cm is negatively associated with DFS, RM after CIA is not associated with poor prognosis. PMID:27057900

  5. Intensity modulated radiotherapy (IMRT) combined with concurrent but not adjuvant chemotherapy in primary nasopharyngeal cancer – a retrospective single center analysis

    We report our experience in 49 consecutive patients with nasopharyngeal carcinoma who were treated by Intensity-modulated radiation therapy (IMRT) combined with simultaneous but not adjuvant chemotherapy (CHT). The medical records of 49 patients with histologically proven primary nasopharygeal carcinoma treated with IMRT and concurrent platin-based CHT (predominantly cisplatin weekly) were retrospectively reviewed. The majority of patients showed advanced clinical stages (stage III/IV:72%) with undifferentiated histology (82%). IMRT was performed in step-and-shoot technique using an integrated boost concept in 84%. In this concept, the boost volume covered the primary tumor and involved nodes with doses of 66–70.4 Gy (single dose 2.2 Gy). Uninvolved regional nodal areas were covered with doses of 54–59.4 Gy (median single dose 1.8 Gy). At least one parotid gland was spared. None of the patients received adjuvant CHT. The median follow-up for the entire cohort was 48 months. Radiation therapy was completed without interruption in all patients and 76% of the patients received at least 80% of the scheduled CHT. Four local recurrences have been observed, transferring into 1-, 3-, and 5-year Local Control (LC) rates of 98%, 90% and 90%. One patient developed an isolated regional nodal recurrence, resulting in 1-, 3-, and 5-year Regional Control (RC) rates of 98%. All locoregional failures were located inside the radiation fields. Distant metastases were found in six patients, transferring into 1-, 3, and 5-year Distant Control (DC) rates of 92%, 86% and 86%. Progression free survival (PFS) rates after 1, 3 and 5 years were 86%, 70% and 69% and 1-, 3- and 5-year Overall Survival (OS) rates were 96%, 82% and 79%. Acute toxicity ≥ grade III mainly consisted of dysphagia (32%), leukopenia (24%), stomatitis (16%), infection (8%) and nausea (8%). Severe late toxicity (grade III) was documented in 18% of the patients, mainly as xerostomia (10%). Concurrent chemoradiation

  6. Medulloblastoma in China: clinicopathologic analyses of SHH, WNT, and non-SHH/WNT molecular subgroups reveal different therapeutic responses to adjuvant chemotherapy.

    Zhen-Yu Zhang

    Full Text Available Medulloblastoma (MB is one of the most common primary central nervous system tumors in children. Data is lacking of a large cohort of medulloblastoma patients in China. Also, our knowledge on the sensitivity of different molecular subgroups of MB to adjuvant radiation therapy (RT or chemotherapy (CHT is still limited. The authors performed a retrospective study of 173 medulloblastoma patients treated at two institutions from 2002 to 2011. Formalin-fixed paraffin embedded (FFPE tissues were available in all the cases and sections were stained to classify histological and molecular subgroups. Univariate and multivariate analyses were used to investigate prognostic factors. Of 173 patients, there were 118 children and 55 adults, 112 males and 61 females. Estimated 5-year overall survival (OS rates for all patients, children and adults were 52%, 48% and 63%, respectively. After multivariate analysis, postoperative primary radiation therapy (RT and chemotherapy (CHT were revealed as favorable prognostic factors influencing OS and EFS. Postoperative primary chemotherapy (CHT was found significantly improving the survival of children (p<0.001 while it was not a significant prognostic factor for adult patients. Moreover, patients in WNT subtype had better OS (p = 0.028 than others (SHH and Non-SHH/WNT subtypes given postoperative adjuvant therapies. Postoperative primary RT was found to be a strong prognostic factor influencing the survival in all histological and molecular subgroups (p<0.001. Postoperative primary CHT was found significantly to influence the survival of classic medulloblastoma (CMB (OS p<0.001, EFS p<0.001, SHH subgroup (OS p = 0.020, EFS p = 0.049 and WNT subgroup (OS p = 0.003, EFS p = 0.016 but not in desmoplastic/nodular medulloblastoma (DMB (OS p = 0.361, EFS p = 0.834 and Non-SHH/WNT subgroup (OS p = 0.127, EFS p = 0.055. Our study showed postoperative primary CHT significantly influence the

  7. Consolidation whole abdomen irradiation following adjuvant carboplatin-paclitaxel based chemotherapy for advanced uterine epithelial cancer: feasibility, toxicity and outcomes

    To evaluate feasibility and preliminary outcomes associated with sequential whole abdomen irradiation (WAI) as consolidative treatment following comprehensive surgery and systemic chemotherapy for advanced endometrial cancer. We conducted a retrospective analysis of patients treated at our institution from 2000 to 2011. Inclusion criteria were stage III-IV endometrial cancer patients with histological proof of one or more sites of extra-uterine abdomen-confined disease, treated with WAI as part of multimodal therapy. Endpoints were feasibility, acute toxicity, late effects, recurrence-free survival (RFS) and overall survival (OS). Twenty patients were identified. Chemotherapy consisted of 3 to 6 cycles of a platinum-paclitaxel regimen in 18 patients. WAI was delivered using conventional technique to a median total dose of 27.5 Gy. No grade 4 toxicities occurred during chemotherapy or radiotherapy. No radiation dose reduction was necessary. Three patients developed small bowel obstruction, all in the context of recurrent intraperitoneal disease. Kaplan-Meier estimates and 95% confidence intervals for RFS and OS at one year were 63% (38–80%) and 83% (56-94%) and at 3 years 57% (33-76%) and 62% (34-81%), respectively. On univariate Cox analysis, stage IVB and serous papillary (SP) histology were found to be statistically significantly (at the p = 0.05 level) associated with worse RFS and OS. The peritoneal cavity was the most frequent site of initial failure. Consolidative WAI following chemotherapy is feasible and can be performed without interruption with manageable acute and late toxicity. Patients with endometrioid adenocarcinoma, especially stage FIGO III, had favorable outcomes possibly meriting prospective evaluation of the addition of WAI following chemotherapy in selected patients. Patients with SP do poorly and do not routinely benefit from this approach

    Full Text Available Abstract Background HER2 and TOP2A parameters (gene status, mRNA and protein expression have individually been associated with the outcome of patients treated with anthracyclines. The aim of this study was to comprehensively evaluate the prognostic/predictive significance of the above parameters in early, high-risk breast cancer patients treated with epirubicin-based, dose-dense sequential adjuvant chemotherapy. Methods In a series of 352 breast carcinoma tissues from patients that had been post-operatively treated with epirubicin-CMF with or without paclitaxel, we assessed HER2 and TOP2A gene status (chromogenic in situ hybridization, mRNA expression (quantitative reverse transcription PCR, as well as HER2 and TopoIIa protein expression (immunohistochemistry. Results HER2 and TOP2A amplification did not share the same effects on their downstream molecules, with consistent patterns observed in HER2 mRNA and protein expression according to HER2 amplification (all parameters strongly inter-related, p values Conclusions This study confirms the favorable prognostic value of HER2/TOP2A co-amplification and the adverse prognostic value of high TOP2A mRNA expression extending it to the adjuvant treatment setting in early high-risk breast cancer. The strong adverse prognostic impact of high HER2/TOP2A mRNA co-expression needs further validation in studies designed to evaluate markers predictive for anthracyclines.

  9. Significance of PIK3CA Mutations in Patients with Early Breast Cancer Treated with Adjuvant Chemotherapy: A Hellenic Cooperative Oncology Group (HeCOG Study.

    George Papaxoinis

    Full Text Available The PI3K-AKT pathway is frequently activated in breast cancer. PIK3CA mutations are most frequently found in the helical (exon 9 and kinase (exon 20 domains of this protein. The aim of the present study was to examine the role of different types of PIK3CA mutations in combination with molecular biomarkers related to PI3K-AKT signaling in patients with early breast cancer.Tumor tissue samples from 1008 early breast cancer patients treated with adjuvant chemotherapy in two similar randomized trials of HeCOG were examined. Tumors were subtyped with immunohistochemistry (IHC and FISH for ER, PgR, Ki67, HER2 and androgen receptor (AR. PIK3CA mutations were analyzed by Sanger sequencing (exon 20 and qPCR (exon 9 (Sanger/qPCR mutations. In 610 cases, next generation sequencing (NGS PIK3CA mutation data were also available. PIK3CA mutations and PTEN protein expression (IHC were analyzed in luminal tumors (ER and/or PgR positive, molecular apocrine carcinomas (MAC; ER/PgR negative / AR positive and hormone receptor (ER/PgR/AR negative tumors.PIK3CA mutations were detected in 235/1008 tumors (23% with Sanger/qPCR and in 149/610 tumors (24% with NGS. Concordance between the two methods was good with a Kappa coefficient of 0.76 (95% CI 0.69-0.82. Lobular histology, low tumor grade and luminal A tumors were associated with helical domain mutations (PIK3CAhel, while luminal B with kinase domain mutations (PIK3CAkin. The overall incidence of PIK3CA mutations was higher in luminal as compared to MAC and hormone receptor negative tumors (p = 0.004. Disease-free and overall survival did not significantly differ with respect to PIK3CA mutation presence and type. However, a statistically significant interaction between PIK3CA mutation status and PTEN low protein expression with regard to prognosis was identified.The present study did not show any prognostic significance of specific PIK3CA mutations in a large group of predominantly lymph-node positive breast cancer

    Objective: The proper time to commence adjuvant chemotherapy after primary surgery for breast cancer is unknown. It is usually prescribed within 2-3 months after definitive surgery. The aim of this retrospective study was to assess the impact of adjuvant chemotherapy (CT) delay beyond 3 weeks ( 21 days) in premenopausal patients with ER-absent tumors being treated for early stages breast cancer on overall survival (OS) and disease-free survival (DFS). Methods: This retrospective study was conducted through revision of medical records of premenopausal patients diagnosed with early stage I-IIIA breast cancer and ER-absent tumors who received adjuvant CT after definitive surgery at the Department of Clinical Oncology, Ain-Shams University Hospitals. Results: Between 2005 and 2008, 105 patients were retrospectively analyzed and included. Patients were divided into 2 groups: Group A including 48 patients who started adjuvant CT < 21 days of surgery and group B which included 57 patients who had CT delay < 21 days. Both groups were matched demographically. Comparisons of overall survival, and disease-free survival between group A and group B patients all favored group A. At 5-year the OS rates were 87% and 73% for groups A and B respectively (P = 0.001), while DFS rates were 85% and 64% in groups A and B respectively (P = 0.001). Analysis of other prognostic factors (age, T, N, grade, HER2 status, surgery type, CT type, local radiotherapy received) were analyzed. Only nodal status predicted for worse DFS (P = 0.05) and OS (P = 0.006). Conclusion: Delay in initiating adjuvant chemotherapy for early stage breast cancer patients with ER-absent tumors was associated with a decrease in both OS and DFS rates.

  11. Immunohistochemical expression of carcinoembryonic antigen-related cell adhesion molecules 5, CEACAM6, and SLC7A5: Do they aid in predicting the response to neo-adjuvant chemotherapy in locally advanced breast cancer?

    2014-01-01

    Context: Neo-adjuvant chemotherapy (NACT) has become an integral part of multimodality treatment for locally advanced breast cancer (LABC) worldwide. Predictors of therapeutic response to NACT are lacking. Whether carcinoembryonic antigen-related cell adhesion molecules (CEACAMs) like CEACAM5 and CEACAM6 can act as a predictor of response to therapy is unclear. SLC7A5 gene in humans encodes a large neutral amino acid transporter protein, which has an essential role in tumor cell growth and su...

  12. Fibroblastic growth factor receptor 1 amplification in osteosarcoma is associated with poor response to neo-adjuvant chemotherapy

    Osteosarcoma, the most common primary bone sarcoma, is a genetically complex disease with no widely accepted biomarker to allow stratification of patients for treatment. After a recent report of one osteosarcoma cell line and one tumor exhibiting fibroblastic growth factor receptor 1 (FGFR1) gene amplification, the aim of this work was to assess the frequency of FGFR1 amplification in a larger cohort of osteosarcoma and to determine if this biomarker could be used for stratification of patients for treatment. About 352 osteosarcoma samples from 288 patients were analyzed for FGFR1 amplification by interphase fluorescence in situ hybridization. FGFR1 amplification was detected in 18.5% of patients whose tumors revealed a poor response to chemotherapy, and no patients whose tumors responded well to therapy harbored this genetic alteration. FGFR1 amplification is present disproportionately in the rarer histological variants of osteosarcoma. This study provides a rationale for inclusion of patients with osteosarcoma in clinical trials using FGFR kinase inhibitors

    Purpose: to prospectively assess health-related quality of life (HR-QoL) in women after conserving surgery for breast cancer during/after postoperative 3-D radiotherapy. Patients and methods: 109 consecutively treated patients were analyzed. HR-QoL was assessed at initiation (t1), end (t2), and 6 weeks after radiotherapy (t3) using the EORTC modules QLQ-C30/BR23. Patients were divided into three therapy groups. Group I comprised 41 patients (radiotherapy and adjuvant chemotherapy), group II 45 patients (radiotherapy and adjuvant hormonal therapy), and group III 23 patients (radiotherapy alone). Reliability was tested. Scale means were calculated. Univariate (ANOVA) and multivariate (MANCOVA) analyses were performed. Results: reliability testing revealed mean Cronbach's {alpha} > 0.70 at all measurement points. ANOVA/MANCOVA statistics revealed significantly better HR-QoL for patients in group II versus I. Patients receiving radiotherapy alone (group III) showed the best results in HR-QoL. However, scale mean differences between groups II and III were not significant. Conclusion: HR-QoL measurement using EORTC instruments during/after radiotherapy is reliable. Adjuvant chemotherapy significantly lowered HR-QoL versus hormones or radiotherapy alone. Chemotherapy patients did not recover longitudinally (from t1 to t3). (orig.)

    Cisplatin is one of the most effective chemotherapeutic agents for the treatment of lung cancer. However, the acquired resistance occurred in cancer cells limits the clinical application of cisplatin. MCL-1, which is an important member in the pro-survival Bcl-2 family, plays a critical role in multidrug resistance (MDR). The aim of the present study is to investigate the value of Pan-Bcl-2 inhibitor as sensitizer for the chemotherapy of cisplatin-resistant non-small cell lung cancer (NSCLC) cells. We found the obatoclax but not the ABT-737 significantly decreased the IC50 (half maximal inhibitory concentration) of cisplatin in cisplatin-resistant NSCLC cells. Furthermore, we demonstrated that the mechanism of obatoclax-promoted cell death induced by cisplatin was dependent on the inhibition of MCL-1, which couldn't be inhibited by ABT-737 but is the target of obatoclax. Moreover, inhibition of MCL-1 recovered the function of NOXA and BAK in cisplatin-resistant NSCLC cells, leading to the promotion of mitochondrial apoptosis induced by cisplatin. Interestingly, our date indicated the obatoclax also reversed the cross-resistance in cisplatin-resistant NSCLC cells. Therefore, we demonstrated that the targeted therapy with MCL-1 inhibitors, such as obatoclax, may represent a novel strategy for cancer therapy. PMID:27138804

  20. Supratentorial primitive neuroectodermal tumors (S-PNET) in children: A prospective experience with adjuvant intensive chemotherapy and hyperfractionated accelerated radiotherapy

    Purpose: Supratentorial primitive neuroectodermal tumors (S-PNET) are rare and have a grim prognosis, frequently taking an aggressive course with local relapse and metastatic spread. We report the results of a mono-institutional therapeutic trial. Methods and Materials: We enrolled 15 consecutive patients to preradiation chemotherapy (CT) consisting of high-dose methotrexate, high-dose etoposide, high-dose cyclophosphamide, and high-dose carboplatin, craniospinal irradiation (CSI) with hyperfractionated accelerated radiotherapy (HART) plus focal boost, maintenance with vincristine/lomustine or consolidation with high-dose thiotepa followed by autologous stem-cell rescue. Results: Median age was 9 years; 7 were male, 8 female. Site of disease was pineal in 3, elsewhere in 12. Six patients were had no evidence of disease after surgery (NED). Of those with evidence of disease after surgery (ED), 2 had central nervous system spread. Of the 9 ED patients, 2 had complete response (CR) and 2 partial response (PR) after CT, 4 stable disease, and 1 progressive disease. Of the 7 ED patients before radiotherapy, 1 had CR, 4 PR, and 2 minor response, thus obtaining a 44% CR + PR after CT and 71% after HART. Because of rapid progression in 2 of the first 5 patients, high-dose thiotepa was systematically adopted after HART in the subsequent 10 patients. Six of 15 patients relapsed (4 locally, 1 locally with dissemination, 1 with dissemination) a mean of 6 months after starting CT, 2 developed second tumors; 5 of 6 relapsers died at a median of 13 months. Three-year progression-free survival, event-free survival, and overall survival were 54%, 34%, and 61%, respectively. Conclusion: Hyperfractionated accelerated RT was the main tool in obtaining responses in S-PNET; introducing the myeloablative phase improved the prognosis (3/10 vs. 3/5 relapses), though the outcome remained unsatisfactory despite the adoption of this intensive treatment

    Full Text Available Context: The therapeutic strategy in intermediate risk (IR non-muscle invasive bladder cancer (NMIBC recurring after intravesical therapy (IT is not well defined. Most patients are usually retreated by Bacillus Calmette-Guerin (BCG. Aims: To evaluate the efficacy of intravesical chemotherapy (ICH given at recurrence after the first cycle of ICH in IR-NMIBC recurring 6 months or later. Settings and Design: Retrospective analysis of the efficacy of ICH given after previous IT. Materials and Methods: The clinical files of IR-NMIBC patients recurring later than 6 months after transurethral resection (TUR and IT and retreated by IT were reviewed. The patients should be at intermediate risk both initially and at the first recurrence. BCG should have been given at full dose. Cytology and cystoscopy were performed 3 monthly for 2 years and then 6 monthly. Statistical Analysis: The RFS was estimated by the Kaplan-Meier method and the differences between treatment groups were compared by log-rank test. Mann Whitney U-test was used to compare the parameters′ distribution for median time to recurrence. Multivariate Cox proportional hazards models were used. Results: The study included 179 patients. The first IT was ICH in 146 (81.6% and BCG in 33 (18.4%, re-IT was ICH in 112 (62.6% and BCG in 67 (37.4% patients. Median time to recurrence was 18 and 16 months after first and second IT (P = 0.32. At 3 years, 24 (35.8% and 49 (43.8% patients recurred after BCG and ICH, respectively (P = 0.90. No difference in RFS was found between BCG and ICH given after a first cycle of ICH (P = 0.23. Conclusions: Re-treatment with ICH could represent a legitimate option to BCG in patients harboring IR-NMIBC recurring after TUR and previous ICH. Prospective trials are needed.

    Objective:The aim of this study was to evaluate the effect of the excision repair cross-complementing (ERCC1) expression on survival in advanced gastric cancer patients who underwent surgical resection and treated with oxaliplatin-based adjuvant chemotherapy. Methods: Sixty-three patients who underwent surgical resection for cure and treated with oxaliplatin-based adjuvant chemotherapy were included in this study. The expressions of ERCC1 of gastric cancer were examined by immunohistochemistry and the patients were categorized into ERCC1-(+) and ERCC1-(-) groups. The relation between ERCC1 expression and survival of patients was examined. Results: Of the 63 eligible patients, 36 patients (57.1%) had tumor with a positive expression of ERCC1 and the remaining 27 patients had tumor with a negative ERCC1 expression. Expression differences of ERCC1 didn't correlated with age (P - 0.827), gender (P = 0.12), differentiation (P = 0.113), historical type (P = 0.942), site of tumor (P = 0.221), size of tumor (P = 0.608), stage (P = 0.815) and lymphatic invasion (P = 0.165). Overall survival (OS) was significantly longer in patients without ERCC1 expression, when compared to patients with ERCC1 expression (P = 0.023). Multivariate analysis revealed that ERCC1 expression significantly impacted on OS (MR: 4.049; P = 0.000). Conclusion: We concluded that resected and treated with oxaliplatin-based adjuvant chemotherapy gastric cancer patients without ERCC1 expression have a better survival when compared to patients with ERCC1 expression. ERCC1 expression will hopefully provide a rational basis for improving adjuvant chemotherapeutic strategies for gastric cancer patients. ERCC1, itself, may be a prognostic factor for gastric cancer.

    Docetaxel is an antineoplastic drug from the taxane family that inhibits tubulin polymerization. Its brand name is Taxotere. In mid-2010, the formulation of Taxotere changed from a two-vial preparation needing a predilution (T2V) to a one-vial ready-to-use preparation (T1V). The aim of this study was to compare the toxicity profile of these two formulations. This retrospective observational and monocentric study included all patients who received Taxotere-based chemotherapy (100 mg/m) as an adjuvant or a neoadjuvant treatment for localized breast cancer, following initial treatment with anthracycline-based chemotherapy. Patients received either T2V or T1V Taxotere depending on the period of treatment. The main endpoint was the ratio of the dose of Taxotere received to that scheduled (R=docetaxel dose received/docetaxel dose scheduled). The secondary endpoint was tolerance. A total of 97 patients were included: 39 in the T2V group and 58 in the T1V group. The ratio of docetaxel received/docetaxel scheduled was significantly lower in the T1V than in the T2V group (0.83 vs. 0.95, respectively; P=0.028). A higher proportion of patients did not receive the totality of the scheduled dose in the T1V than in the T2V group (28 vs. 8%, respectively; P=0.03). Furthermore, the proportion of patients experiencing cutaneous toxicity was significantly higher in the T1V than in the T2V group (50 vs. 15%, respectively; P<0.001) as well as for neurological toxicity (31 vs. 15%, respectively; P=0.03). The frequency of grade 3 toxicities was higher in the T1V than in the T2V group (50 vs. 8%, P=0.016). The frequency of idiosyncratic toxicities was not affected by the change of formulation (4.7 vs. 5.4%, P=0.98). This study shows that patients treated with the T1V formulation received a significantly smaller dose of Taxotere than patients treated with T2V. In this small retrospective study, no conclusions can be drawn as to why a change in formulation would be associated with

    The benefit of adjuvant chemotherapy (AC) in locoregionally advanced nasopharyngeal carcinoma (NPC) is controversial. This study compared concurrent chemoradiotherapy plus AC (CCRT/AC) with CCRT. Pair-matched analysis based on eight clinicopathological features of 244 patients treated with platinum-based CCRT/AC or CCRT alone was performed. Survival outcomes were assessed using the Kaplan-Meier method and log-rank test. Toxicities and response rates were compared using Fisher's exact test. Four-year overall survival, progression-free survival, distant failure-free survival, and locoregional failure-free survival were 72 %, 61 %, 71 %, and 81 %, respectively, for the CCRT arm, compared to 74 % (hazard ratio, HR 0.89; 95 % confidence interval, CI 0.64-1.23; P = 0.474), 62 % (HR 0.91, 95 % CI 0.68-1.20, P = 0.489), 73 % (HR 0.84, 95 % CI 0.59-1.18, P = 0.316), and 84 % (HR 0.84, 95 % CI 0.52-1.24, P = 0.323), respectively, for the CCRT/AC arm. Cox multivariate regression analysis demonstrated AC was not an independent prognostic factor. Overall, there was a higher incidence of grade 3-4 toxicities in the CCRT/AC arm. The most common grade 3-4 adverse events in the CCRT/AC arm were vomiting (27 %), nausea (43 %), leukopenia/neutropenia (23 %), thrombocytopenia (8.8 %), and anemia (6.2 %). Addition of AC to CCRT increased toxicities but did not improve survival in locoregionally advanced NPC. (orig.)

    Introduction MicroRNAs (miRNAs) are small non-coding RNA that plays a vital role in cancer progression. Neo-adjuvant chemotherapy (NAC) has become the standard of care for locally advanced breast cancer. The aim of this study was to evaluate miRNA alterations during NAC using multiple samples of tissue and serum to correlate miRNA expression with clinico-pathological features and patient outcomes. Methods Tissue and serum samples were collected from patients with locally advanced breast cancer undergoing NAC at four time points: time of diagnosis, after the first and fourth cycle of doxorubicin/cyclophosphamide treatment, and after the fourth cycle of docetaxel administration. First, we evaluated the miRNA expression profiles in tissue and correlated expression with clinico-pathological features. Then, a panel of four miRNAs (miR-451, miR-3200, miR-21, and miR-205) in serum samples was further validated using quantitative reverse-transcription polymerase chain reaction (RT-qPCR). The alterations in serum levels of miRNA, associations with clinical and pathological responses, correlation with clinico-pathological features, and survival outcomes were studied using Friedman, Mann-Whitney U, and Spearman, Wilcoxon signed-ranks tests. P≤0.05 was considered statistically significant. Results We analyzed 72 tissue samples and 108 serum samples from 9 patients and 27 patients, respectively. MicroRNA expression profiling of tumor versus normal tissue revealed more than 100 differentially expressed miRNAs. Serum miR-451 levels were significantly decreased during treatment, and higher serum levels were associated with improved clinical and pathological responses and disease-free survival. This is one of the early reports on miR-3200 in response to treatment in breast cancer, as serum levels of miR-3200 found to decline during NAC, and higher serum levels were associated with lower residual breast cancer burden and relapse rates at time of diagnosis. Conclusion Variations in

    Recently, it has been reported that the relative dose intensity (RDI) of adjuvant chemotherapy (AC) influences survival in various cancers, but there are very few reports about RDI in pancreatic ductal adenocarcinoma (PDAC). The optimal timing for initiation of AC for PDAC also remains unknown. The aim of this study was to identify the significance of RDI and the time interval between surgery and initiation of AC on survival of patients with PDAC. Clinicopathological factors that affect RDI were also investigated.A total of 311 consecutive PDAC patients who underwent curative resection between May 2005 and January 2015 were enrolled. Patients who underwent neoadjuvant chemoradiation, had UICC stage IV disease, or had early recurrences within 6 months were excluded, and the remaining 168 cases were analyzed.Patients with RDIs ≥80% (n = 79) showed significantly better overall survival (OS) compared to patients with RDIs MST): 45.6 months, 26.0 months, P MST: 20.8 months). Whether the AC was initiated earlier or later than 8 weeks after surgery did not influence survival, either in patients with RDIs ≥80% (P = 0.79) or in those with MST: 95.0 months, 26.0 months, respectively; P = 0.001). Univariate analysis conducted after adjusting for the chemotherapeutic drug used identified several prognostic factors; male gender (P = 0.01), intraoperative blood transfusion (P = 0.005), lymph node metastasis (P = 0.03), and postoperative WBC count (P = 0.03). Multivariate analysis identified intra-plus postoperative blood transfusion (P = 0.002) and high postoperative platelet-to-lymphocyte ratios (PLR) (P = 0.04) as independent predictors of poor RDI.Efforts to maintain RDI had a greater impact on survival than the struggle to start AC early after surgery. Intra-plus postoperative blood transfusion and a high postoperative PLR could be predictive markers of reduced RDI in AC of PDAC patients. Avoidance of perioperative blood transfusions

    Resection of biopsy-proven involved axillary lymph nodes (iALNs) is important to reduce the false-negative rates of sentinel lymph node (SLN) biopsy after neo-adjuvant chemotherapy (NAC) in patients with initially node-positive breast cancer. Preoperative wire localization for iALNs marked with clips placed during biopsy is a technique that may help the removal of iALNs after NAC. However, ultrasound (US)-guided localization is often difficult because the clips cannot always be reliably visible on US. Computed tomography (CT)-guided wire localization can be used; however, to date there have been no reports on CT-guided wire localization for iALNs. The aim of this study was to describe a series of patients who received CT-guided wire localization for iALN removal after NAC and to evaluate the feasibility of this technique. We retrospectively analyzed five women with initially node-positive breast cancer (age, 41-52 years) who were scheduled for SLN biopsy after NAC and received preoperative CT-guided wire localization for iALNs. CT visualized all the clips that were not identified on post-NAC US. The wire tip was deployed beyond or at the target, with the shortest distance between the wire and the index clip ranging from 0 to 2.5 mm. The total procedure time was 21-38 minutes with good patient tolerance and no complications. In four of five cases, CT wire localization aided in identification and resection of iALNs that were not identified with lymphatic mapping. Residual nodal disease was confirmed in two cases: both had residual disease in wire-localized lymph nodes in addition to SLNs. Although further studies with more cases are required, our results suggest that CT-guided wire localization for iALNs is a feasible technique that facilitates identification and removal of the iALNs as part of SLN biopsy after NAC in situations where US localization is unsuccessful.

    Purpose: To evaluate adjuvant chemotherapy and interpolated accelerated radiotherapy (RT) for adult patients with high-risk soft tissue sarcoma in the extremities or trunk wall. Methods and Materials: High-risk soft tissue sarcoma was defined as high-grade malignancy and at least two of the following criteria: size {>=}8 cm, vascular invasion, or necrosis. Six cycles of doxorubicin and ifosfamide were prescribed for all patients. RT to a total dose of 36 Gy (1.8 Gy twice daily) was inserted between two chemotherapy cycles after marginal margin resection regardless of tumor depth or after wide-margin resection for deep-seated tumors. RT was boosted to 45 Gy in a split-course design in the case of intralesional margin resection. Results: A total of 119 patients were eligible, with a median follow-up of 5 years. The 5-year estimate of the local recurrence, metastasis-free survival, and overall survival rate was 12%, 59%, and 68%, respectively. The group receiving RT to 36 Gy had a local recurrence rate of 10%. In contrast, the local recurrence rate was 29% in the group treated with RT to 45 Gy. The presence of vascular invasion and low chemotherapy dose intensity had a negative effect on metastasis-free and overall survival. Toxicity was moderate after both the chemotherapy and the RT. Conclusions: Accelerated RT interposed between chemotherapy cycles in a selected population of patients with high-risk soft tissue sarcoma resulted in good local and distant disease control, with acceptable treatment-related morbidity. The greater radiation dose administered after intralesional surgery was not sufficient to compensate for the poorer surgical margin. Vascular invasion was the most important prognostic factor for metastasis-free and overall survival.

    Purpose: Neo-adjuvant chemotherapy generally induces significant changes in the pathological extent of disease. This potential down-staging challenges the standard indications of adjuvant radiation therapy. We assessed the utility of lymph node irradiation in breast cancer patients with pathological N0 status (pN0) after neo-adjuvant chemotherapy and breast-conserving surgery. Patients and materials: Among 1054 breast cancer patients treated with neo-adjuvant chemotherapy in our institution between 1990 and 2004, 248 patients with clinical N0 or N1-N2 lymph node status at diagnosis had pN0 status after neo-adjuvant chemotherapy and breast-conserving surgery. Cox regression analysis was used to identify factors influencing locoregional recurrence-free survival, disease-free survival and overall survival. Results: All 248 patients received breast irradiation, and 158 patients (63.7%) also received lymph node irradiation. With a median follow-up of 88 months, the 5-year locoregional recurrence-free survival and overall survival rates were respectively 89.4% and 88.7% with lymph node irradiation and 86.2% and 92% without lymph node irradiation (no significant difference). Survival was poorer among patients who did not have a pathological complete primary tumor response (pCR) (hazards ratio [HR] = 3.05; 95% CI, 1.17 to 7.99) and in patients with N1-N2 clinical status at diagnosis ([HR] = 2.24; 95% CI, 1.15 to 4.36). Lymph node irradiation did not significantly affect survival. Conclusions: Relative to combined breast and local lymph node irradiation, isolated breast irradiation does not appear to be associated with a higher risk of locoregional relapse or death among breast cancer patients with pN0 status after neo-adjuvant chemotherapy. These results need to be confirmed in a prospective study. (authors)

    目的 探讨新辅助化学疗法(化疗)对结直肠癌手术患者炎症因子水平的影响.方法 回顾2008年1月-2009年12月诊断为结直肠癌的487例患者的临床资料,剔除不符合研究条件者后,共390例,以是否接受过新辅助化疗分为术前化疗组(化疗组)156例与对照组234例进行研究.分别比较两组在入院时、术前、术后的炎症因子水平.结果 入院时两组外周血白细胞、C反应蛋白(CRP)、纤维蛋白原、血清淀粉样蛋白水平差异均无统计学意义(P>0.05);术后化疗组CRP水平[(64.09±60.24)mg/L]低于对照组[(87.80±61.54)mg/L],差异有统计学意义(P<0.05);其余炎症因子组间差异无统计学意义(P>0.05).结论 新辅助化疗不会刺激机体产生免疫反应,且有一定的安全性.%Objective To evaluate the security of neo-adjuvant chemotherapy by testing the level of such non-specific chemokines as C-reactive protein (CRP), fibrinogen (FIB) and serum amyloid A (SAA). Methods There were 487 patients with colorectal cancer accepted in West China Hospital between January 2008 and December 2009, and 97 of them didn't conform to the study including standard. The rest 390 patients were assigned to 2 groups, including 156 in the control group and 234 in the neo-adjuvant chemotherapy group. The level of chemokines were measured and compared between the two groups at the time of acceptance, before and after surgery. Results The increase of CRP after the surgery was signifigantly higher in the neo-adjuvant chemotherapy group [(87.80 ± 61.54) mg/L] than that in the chemotherapy group [(64.09 ± 60.24) mg/L)] (P < 0.05). The level of WBC, CRP and SAA increased after the surgery compared with the time of the acceptance (P < 0.05). Conclusion The neo-adjuvant chemotherapy will not irritate the immune system, which may be considered as a therapy of certain safety.

    Full Text Available There is no clear consensus on what type of adjuvant therapy should be used for patients with pancreatic cancer. Chemoradiation is the favored treatment modality by many in the United States while gemcitabine based chemotherapy is favored in Europe. Both of these approaches have been shown by large prospective, randomized trials to improve disease free intervals and in some studies overall survival. This year at the American Society of Clinical Oncology (ASCO Gastrointestinal Cancer Symposium, the randomized phase III study presented by Uesaka et al. from Japan (Abstract #145 represents a newer paradigm of oral adjuvant S-1 chemotherapy in place of the traditional standard of care intravenous gemcitabine in terms of prolonging patients’ survival. Another study by Fan et al. (Abstract #269 examined the value of targeted therapy using erlotinib with adjuvant chemoradiation and chemotherapy. We present the summary of these two studies and discuss the potential impact on our clinical practice on this highly lethal cancer.

    2014-01-01

    BACKGROUND: The CAPOX regimen is used for adjuvant treatment of colorectal cancer. A well-known side effect of oxaliplatin, which often leads to dose modification (DM), is acute neuropathy (AN). AN is provoked by cold, and it could therefore be expected that the degree of AN and thereby DM is mor...

  20. Evaluation of adjuvant chemoradiation therapy for ampullary adenocarcinoma: the Johns Hopkins Hospital - Mayo Clinic collaborative study

    The role of adjuvant chemoradiation therapy for ampullary carcinoma is unknown. Previous literature suggests that certain populations with high risk factors for recurrence may benefit from adjuvant chemoradiation. We combined the experience of two institutions to better delineate which patients may benefit from adjuvant chemoradiation. Patients who underwent curative surgery for ampullary carcinoma at the Johns Hopkins Hospital (n = 290; 1992-2007) and at the Mayo Clinic (n = 130; 1977-2005) were reviewed. Patients with <60 days of follow-up, metastatic disease at surgery, or insufficient pathologic data were excluded. The final combined study consisted of 186 patients (n = 104 Johns Hopkins, n = 82 Mayo). Most patients received 5-FU based chemoradiation with conformal radiation. Cox proportional hazards models were used for survival analysis. Median overall-survival was 39.9 months with 2- and 5-year survival rates of 62.4% and 39.1%. On univariate analysis, adverse prognostic factors for overall survival included T3/T4 stage disease (RR = 1.86, p = 0.002), node positive status (RR = 3.18, p < 0.001), and poor histological grade (RR = 1.69, p = 0.011). Patients who received adjuvant chemoradiation (n = 66) vs. surgery alone (n = 120) showed a higher rate of T3/T4 stage disease (57.6% vs. 30.8%, P < 0.001), lymph node involvement (72.7% vs. 30.0%, P < 0.001), and close or positive margins (4.6% vs. 0.0%, P = 0.019). Five year survival rates among node negative and node positive patients were 58.7% and 18.4% respectively. When compared with surgery alone, use of adjuvant chemoradiation improved survival among node positive patients (mOS 32.1 vs. 15.7 mos, 5 yr OS: 27.5% vs. 5.9%; RR = 0.47, P = 0.004). After adjusting for adverse prognostic factors on multivariate analysis, patients treated with adjuvant chemoradiation demonstrated a significant survival benefit (RR = 0.40, P < 0.001). Disease relapse occurred in 37.1% of all patients, most commonly metastatic

  1. Lack of TIMP-1 tumour cell immunoreactivity predicts effect of adjuvant anthracycline-based chemotherapy in patients (n=647) with primary breast cancer

    2009-01-01

    PURPOSE: A number of prospective studies have shown that adjuvant CEF significantly improves disease-free and overall survival as compared to CMF in breast cancer patients. Our aim was to determine whether the benefit of epirubicin versus methotrexate differs according to TIMP-1 tumour cell...... immunohistochemistry (IHC). Tumours were regarded as TIMP-1 positive if epithelial breast cancer cells were stained using the anti-TIMP-1 monoclonal antibody VT7. RESULTS: By central assessment 75% of tumours were classified as tumour cell TIMP-1 positive. Among CEF-treated patients, individuals with TIMP-1 negative...... immunoreactivity seems to predict a favourable effect of epirubicin-containing adjuvant therapy in primary breast cancer. However, an independent study is awaited to validate the potential predictive value of TIMP-1 immunoreactivity...

    2016-01-01

    Conclusion: Our study demonstrated that the concurrent administration of chemotherapy (anthracycline-based and radiotherapy was superior to the sequential administration in locoregional recurrence-free survival for the operable node positive breast cancer patients. However, choose of treatment for operable breast cancer patients must be cautious due to high risk of lymphedema.

  3. Immunohistochemical expression of carcinoembryonic antigen-related cell adhesion molecules 5, CEACAM6, and SLC7A5: Do they aid in predicting the response to neo-adjuvant chemotherapy in locally advanced breast cancer?

    2014-01-01

    Full Text Available Context: Neo-adjuvant chemotherapy (NACT has become an integral part of multimodality treatment for locally advanced breast cancer (LABC worldwide. Predictors of therapeutic response to NACT are lacking. Whether carcinoembryonic antigen-related cell adhesion molecules (CEACAMs like CEACAM5 and CEACAM6 can act as a predictor of response to therapy is unclear. SLC7A5 gene in humans encodes a large neutral amino acid transporter protein, which has an essential role in tumor cell growth and survival. Materials and Methods: Thirty histopathologically proven cases of LABC, being given NACT, were included in the study. Immunohistochemical examination of the tumor sections was performed for CEACAM5, CEACAM6, and SLC7A5. Response to chemotherapy was assessed using "Response Evaluation Criteria in Solid Tumors" (RECIST 1.1 criteria. A total of three cycles were given at 3 weekly intervals. After 3 weeks of the last cycle of NACT, the patients were taken up for modified radical mastectomy. The specimen was subjected to histopathological examination. The immunohistochemical results were correlated with response to NACT based on RECIST criteria and histopathology. Results: 12/30 (40% of the patients had objective clinical response of which 4 (13.33% patients had pathological complete response. The relationship between CEACAM5 and CEACAM6 and response to NACT was found to be statistically significant, P = 0.004 and P = 0.020, respectively. Furthermore, relationship between response to NACT and node-positive tumors with SLC7A5 immunoreactivity was found to be highly significant (P = 0.009. Conclusion: Biomarkers (CEACAM5, CEACAM6, and SLC7A5 showed promise as predictors of poor response to NACT and can help plan an alternative regime in likely nonresponders to prevent the toxicity of chemotherapy and also in tailoring the therapy in a patient with LABC.

  7. Alterations in EGFR and related genes following neo-adjuvant chemotherapy in Chinese patients with non-small cell lung cancer.

    Shuhang Wang

    Full Text Available INTRODUCTION: Genetic aberrancies within epidermal growth factor receptor (EGFR pathway are associated with therapeutic outcomes of EGFR-tyrosine kinase inhibitors (TKIs in advanced non-small cell lung cancer (NSCLC. However, the impact of chemotherapy on EGFR-related genes alterations has not been defined in NSCLC. Our study aims to investigate the impact of neoadjuvant chemotherapy (Neoadj-Chemo on EGFR activating mutations and associated EGFR-TKIs resistance-related genes. PATIENTS AND METHODS: Matched tumor samples were obtained retrospectively from 66 NSCLC patients (stages IIb-IIIb corresponding to pre- and post- Neoadj-Chemo. EGFR mutations were detected by denaturing high performance liquid chromatography (DHPLC and confirmed by Amplification Refractory Mutation System technology (ARMS, KRAS mutations, T790M mutation and c-MET amplification were identified using Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP, ARMS, and real-time PCR, respectively. RESULTS: Before Neoadj-Chemo, EGFR mutations were identified in 33.3% (22/66 of NSCLC patients. Only 18.2% (12/66 of patients carried EGFR mutations after Neoadj-Chemo (p = 0.013. The median peak value of EGFR 19 exon mutations decreased non-significantly after Neoadj-Chemo. KRAS mutation rate decreased from 4.6% (3/66 to 3.0% (2/66 with Neoadj-Chemo. Although the overall percentage of patients exhibiting c-MET amplifications (6.1% [4/66] did not change with Neoadj-Chemo, two patients transitioned from negative to positive c-MET amplification, and two patients reversed these changes post-Neoadj-Chemo. T790M mutations were absent from all samples. CONCLUSION: Neoadjuvant chemotherapy tends to decrease the mutation frequency of EGFR mutation and downstream genes, which suggests that real-time samples analysis for genetic aberrancies within EGFR pathways have important value to delineate specific patient populations and facilitate individualized treatment.

  9. Synergistic effects of laser and adjuvant therapies for cancer: progress in the development of novel cancer treatment methods using combinations of photothermal, photochemical, immunotherapy, and chemotherapy

    Chen, Wei R.; Bartels, Kenneth E.; Korbelik, Mladen; Liu, Hong; Nordquist, Robert E.

    2005-04-01

    Combination therapy has been commonly used in chemotherapy, taking advantage of different effects of different chemotherapeutic agents. The treatment effects are often synergistic. The same approach has been investigated in laser phototherapy. Specifically, different combinations of laser photothermal interaction, laser photochemical interaction, immunotherapy and chemotherapy have been used in the treatment of tumors. These novel approaches showed promise in cancer treatment, particularly against metastatic tumors. The recent development in this area is discussed in this paper. Furthermore, a specific combination of photodynamic therapy (PDT) with a novel immunoadjuvant, glycated chitosan (GC), has shown to be effective in the treatment mammary tumors and lung tumors in mice. In the treatment of EMT6 tumor-bearing mice, the Photofrin-based PDT and GC has significantly increased the survival rates from 37.5% with PDT alone to 62.5% when a 0.1-ml 0.5% GC was peritumoral injected immediately after PDT treatment. The survival rate was further increased to 75.0% when GC of higher concentration was used. In comparison, the individual components of the PDT-GC treatment showed either no effect or very limited effects. In the treatment of a poorly immunogenic tumor model, Line 1 lung tumors in mice, the combination of PDT and GC resulted in a 37.5% survival rate, while no survival mice were observed with PDT alone.

    Purpose. - To assess the benefit of breast surgery for inflammatory breast cancer. Patients and methods. - This retrospective series was based on 232 patients treated for inflammatory breast cancer. All patients received primary chemotherapy followed by either exclusive radiotherapy (118 patients, 51%) or surgery with or without radiotherapy (114 patients, 49%). The median follow-up was 11 years. Results. - The two groups were comparable apart from fewer tumors smaller than 70 mm (43% vs 33%, P = 0.003), a higher rate of clinical stage N2 (15% vs 5%, P = 0.04) and fewer histopathological grade 3 tumors (46% vs 61%, P < 0.05) in the no-surgery group. The addition of surgery was associated with a significant improvement in locoregional disease control (P = 0.04) but with no significant difference in overall survival rates or disease-free intervals. Late toxicities were not significantly different between the two treatment groups except for a higher rate of fibrosis in the no-surgery group (P < 0.0001), and more lymphedema in the surgery group (P = 0.002). Conclusion. - Our data suggest an improvement in locoregional control in patients treated by surgery, in conjunction with chemotherapy and radiotherapy, for inflammatory breast cancer. (authors)

  11. Experience with adjuvant chemotherapy for pseudomyxoma peritonei secondary to mucinous adenocarcinoma of the appendix with oxaliplatin/fluorouracil/leucovorin (FOLFOX4

    Huang Che-Jen

    2008-11-01

    Full Text Available Abstract Background Pseudomyxoma peritonei (PMP is a rare condition characterized by mucinous tumors, disseminated intra-peritoneal implants, and mucinous ascites. So far its diagnosis remains challenging to most clinicians. Case presentation A 55-year-old male patient had suffered from acute onset of abdominal pain and abdominal distension for one day prior to his admission. Physical examination revealed tenderness over the right lower quadrant of the abdomen without diffuse muscle guarding. A large amount of ascites was identified by abdominal computed tomography (CT scan. Paracentesis showed the appearance of sticky mucinous ascites. He underwent laparotomy under the impression of pseudomyxoma peritonei. There was a lot of mucinous ascites, one appendiceal tumor and multiple peritoneal implants disseminated from the subphrenic space to the recto-vesicle pouch. Pseudomyxoma Peritonei caused by mucinous adenocarcinoma of appendiceal origin, was confirmed by histopathology. We performed an excision of the appendiceal tumor combined with copious irrigation and debridement. After the operation, he received 10 cycles of systemic chemotherapy with FOLFOX4 regimen, without specific morbidity. Follow-up of abdominal CT and colonoscopy at post-operative 17 months showed excellent response without evidence of local recurrence or distal metastasis. He made an uneventful recovery (up to the present for 21 months after the operation. Conclusion This case report emphasizes the possible new role of systemic chemotherapy in the treatment of patients with this rare clinical syndrome.

    Purpose: The development of breast cancer-related lymphedema (LE) is closely related to the number of dissected axillary lymph nodes (N-ALNs), chemotherapy, and radiation therapy. In this study, we attempted to estimate the risk of LE based on combinations of these treatment-related factors. Methods and Materials: A total of 772 patients with breast cancer, who underwent primary surgery with axillary lymph node dissection from 2004 to 2009, were retrospectively analyzed. Adjuvant chemotherapy (ACT) was performed in 677 patients (88%). Among patients who received radiation therapy (n=675), 274 (35%) received supraclavicular radiation therapy (SCRT). Results: At a median follow-up of 5.1 years (range, 3.0-8.3 years), 127 patients had developed LE. The overall 5-year cumulative incidence of LE was 17%. Among the 127 affected patients, LE occurred within 2 years after surgery in 97 (76%) and within 3 years in 115 (91%) patients. Multivariate analysis showed that N-ALN (hazard ratio [HR], 2.81; P<.001), ACT (HR, 4.14; P=.048), and SCRT (HR, 3.24; P<.001) were independent risk factors for LE. The total number of risk factors correlated well with the incidence of LE. Patients with no risk or 1 risk factor showed a significantly lower 5-year probability of LE (3%) than patients with 2 (19%) or 3 risk factors (38%) (P<.001). Conclusions: The risk factors associated with LE were N-ALN, ACT, and SCRT. A simple model using combinations of these factors may help clinicians predict the risk of LE.

    2001-01-01

    The outlook for patients with pancreatic cancer has been grim. There have been major advances in the surgical treatment of pancreatic csncer, leading to a drsmatic reduction in post-operative mortality from the development of high volume specialized centres. This stimulated the study of adjuvant and neoadjuvant treatments in pancreatic cancer including chemoradiotherapy and chemotherapy. Initial protocols have been based on the original but rather small GITSG study first reported in 1985. There have been two large European trials totalling over 600 patients (EORTC and ESPAC-1) that do not support the use of chemoradiation as adjuvant therapy. A second major finding from the ESPAC-1 trial (541 patients randomized) was some but not conclusive evidence for a survival benefit associated with chemotherapy. A third major finding from the ESPAC-1 trial was that the quality of life was not affected by the use of adjuvant treatments compared to surgery alone.The ESPAC-3 trial aims to assess the definitive use of adjuvant chemotherapy in a randomized controlled trial of 990 patients.

    The conventional treatment of localized breast cancer involves the use of both systemic therapy and loco-regional radiation after surgery. The ideal sequence of these two treatments is still undefined. This paper focus on our experience of concomitant chemotherapy (CT) and radiotherapy (RT), and discusses information from the literature about this issue. Between Jan,1989 and Jan, 1999 a retrospective analysis of 103 patients with ductal carcinoma of the breast who received concomitant CT with cyclophosphamide, methotrexate and 5 flurouracil (CMF) and RT was made. Radiation did not included mammary chain or axilla and total dose was of 50 Gy. End points were tolerance and oxicity leading changes to doses. Mean age was 44y; median follow up time of 33 mo; 62 patients had breast conserving surgery and 41 had mastectomy. All patients received both treatments without a break or dose modification. There was no change or interruption of RT. Ten out of 103 patients had the prescribed dose of CT decreased of 10%-20%. There was no evident changes in cosmetic results. Most of the knowledge regarding the delay of CT or RT comes from retrospective studies, and results are conflicting. It is well accepted that high risk patients need both CT and RT. However, there are data suggesting that giving RT first and CT after may increase the rate of distant metastases. There are also studies showing worse impact in the local control with the delay of radiotherapy. The use of concomitant chemotherapy and radiotherapy has apparent advantages, but no randomized trial has addressed this issue yet. Our experience has shown that is possible to give concomitant CT with CMF and RT without irradiation of IMC and axilla without major changes in scheduling or dose of both therapies. (author)

    To compare the usefulness of mammography and clinical examination in the evaluation of residual cancer of locally-advanced breast carcinoma treated with neoadjuvant chemotherapy. Among 67 patients with locally advanced breast carcinoma who were treated with neoadjuvant chemotherapy, 18, aged 35-67 (mean, 48) years, underwent mammography before and after this therapy. The 18 sets of mammographs were analyzed retrospectively and compared with the results of clinical examination based on histologic diagnosis. On histologic examinations, 16 of 18 patients (89%) were found to have residual cancer, but in one of these 16, mammography did not show this same result. On mammography, residual cancer was found in 16 patients, but in one of this group, histologic examination did not reveal the same finding. Clinically, a complete response was shown by four patients, and a partial response by 11 ; three showed no response. On histolgogic examination, three of the four patients with complete clinical response were found to have residual cancer. Post-treatment mammographic findings showed that 11 patients had measurable mass ; all of these had residual cancer (positive predictive value : 100%). However, five of seven patients in whom no measurable mass was evident also had residual cancer. Seven of 8 patients in whom microcalcifications were seen on mammography were found to have residual cancer (positive predictive value : 88%). The sensitivity of mammography in predicting residual cancer was greater than that of clinical examination (94% vs 81%), even when microscopic residual cancer was considered as a complete response (92% vs 77%). The specificity of mammography was the same as that of clinical examination(50% vs 50%, 20% vs 20%). In evaluating residual cancer of locally-advanced breast carcinoma after neoadjuvant chemotheragy, mammography is more accurate and informative than clincal examination. In predicting residual cancer, however, it is not accurate enough to replace

    this study, we investigate a large cohort of patients with intermediate-risk BC treated within the WSG EC-DOC Trial for the predictive impact of topoisomerase-II-alpha, HER2/neu, and TIMP-1. Tumor tissue was available in a representative cohort of 772 cases of the WSG EC-DOC Trial collective which......Taxane-anthracycline-based adjuvant chemotherapy is standard of care in patients with node-positive breast cancer (BC) but is also associated with severe side effects and significant costs. It is yet unclear, which biomarkers would predict benefit from taxanes and/or general chemoresistance. In...... status, high TIMP-1 and low topoisomerase-II-alpha protein expression. Significant prognostic factors in multivariate analysis were EC-Doc therapy (HR = 0.61; 95 %CI 0.38-0.986), age <50 years old (HR = 1.682; 95 %CI 1.025-2.579), centrally assessed grade 3 (HR = 4.657; 95 %CI 1.809-11.989), and high Ki...

  18. The treatment of soft-tissue sarcomas of the extremities - prospective randomized evaluations of (1) limb-sparing surgery plus radiation therapy compared with amputation and (2) the role of adjuvant chemotherapy

    Between May 1975 and April 1981, 43 adult patients with high-grade soft tissue sarcomas of the extremities were prospectively randomized to receive either amputation at or above the joint proximal to the tumor, including all involved muscle groups, or to receive a limb-sparing resection plus adjuvant radiation therapy. The limb-sparing resection group received wide local excision followed by 5000 rads to the entire anatomic area at risk for local spread and 6000 to 7000 rads to the tumor bed. Both randomization groups received postoperative chemotherapy with doxorubicin (maximum cumulative dose 550 mg/m2), cyclophosphamide, and high-dose methotrexate. Twenty-seven patients randomized to receive limb-sparing resection and radiotherapy, and 16 received amputation (randomization was 2:1). There were four local recurrences in the limb-sparing group and none in the amputation group (p1 = 0.06 generalized Wilcoxon test). However, there were no differences in disease-free survival rates (83% and 88% at five years; p2 = 0.99) between the limb-sparing group and the amputation treatment groups. Multivariate analysis indicated that the only correlate of local recurrence was the final margin of resection. Patients with positive margins of resection had a higher likelihood of local recurrence compared with those with negative margins (p1 1 = 0.00008) and overall survival (95% vs. 74%; p1 = 0.04)

    Inhibitors of DNA binding/inhibitors of differentiation (Id) protein family have been shown to be involved in carcinogenesis. However, the roles of Id during lung adenocarcinoma (ADC) progression remain unclear. Eighty-eight ADC samples were evaluated for Id-1,2,3 level and angiogenesis (CD 34 and VEGF microvessel density) by immunohistochemistry and morphometry. The impact of these markers was tested on follow-up until death or recurrence. A significant difference between tumor and normal tissue was found for Id-1,2,3 expression (P Id-1 were associated with higher angiogenesis in the tumor stroma (P Id-2, as well as patients in stage-IIb and low Id-3. High cytoplasm Id-3 expression was also directly associated to lymph nodes metastasis (P = 0.05). Patients at stages I to III, with low Id-1 and Id-3 cytoplasm histoscores showed significant long metastasis-free survival time than those with high Id-1 or Id-3 expression (P = 0.04). Furthermore, high MVD-CD34 and MVD-VEGF expression were associated with short recurrence-free survival compared to low MVD-CD34 and MVD-VEGF expressions (P = 0.04). Cox model analyses controlled for age, lymph node metastasis, and adjuvant treatments showed that nuclear Id-1, cytoplasmic Id-3, and MVD-CD34 were significantly associated with survival time. Median score for nuclear Id-1 and cytoplasmic Id-3 divided patients in two groups, being that those with increased Id-1 and Id-3 presented higher risk of death. Ids showed an independent prognostic value in patients with lung ADC, regardless of disease stage. Id-1 and Id-3 should be considered new target candidates in the development of personalized therapy in lung ADC. PMID:26869608

  20. Consolidation chemotherapy during neoadjuvant chemoradiation (CRT) for distal rectal cancer leads to sustained decrease in tumor metabolism when compared to standard CRT regimen

    Neoadjuvant CRT may lead to significant tumor regression in patients with rectal cancer. Different CRT regimens with consolidation chemotherapy may lead to increased rates of complete tumor regression. The purpose of this study was to understand tumor metabolic activity following two different neoadjuvant CRT regimens using sequential PET/CT imaging in two different intervals following RT. Patients with cT2-4 N0-2 M0 rectal cancer treated by standard CRT (54Gy and 2 cycles of 5FU-based chemotherapy) or extended CRT (54Gy and 6 cycles of 5FU-based chemotherapy) underwent sequential PET/CT imaging at baseline, 6 weeks and 12 weeks from radiation completion. 99 patients undergoing standard CRT were compared to 12 patients undergoing CRT with consolidation chemotherapy. Patients treated with consolidation CRT had increased rates of complete clinical or pathological response (66 % vs. 23 %; p < 0.001). SUVmax variation between baseline and 6 weeks (88 % vs. 63 %; p < 0.001) and between baseline and 12 weeks (90 % vs. 57 %; p < 0.001) were significantly more pronounced among patients undergoing extended CRT with consolidation chemotherapy. An increase in SUVmax between 6 and 12 weeks was observed in 51 % of patients undergoing standard and 18 % of patients undergoing consolidation CRT (p = 0.04). Most of the reduction in tumor metabolism after neoadjuvant CRT occurs within the first 6 weeks from RT completion. In patients undergoing CRT with consolidation chemotherapy, tumors are less likely to regain metabolic activity between 6 and 12 weeks. Therefore, assessment of tumor response may be safely postponed to 12 weeks in patients undergoing extended CRT with consolidation chemotherapy.

    Full Text Available El cáncer de pulmón constituye una de las principales causas de mortalidad en todo el mundo. Su incidencia se relaciona directamente al uso del tabaco. Puede clasificarse a los pacientes en tres grupos: con enfermedad localizada o resecable, con enfermedad localmente avanzada y con enfermedad metastásica. Excepto algunos casos, el primer grupo es pasible de curación. En ellos la cirugía es el tratamiento de elección. El advenimiento de quimioterapia sistémica efectiva, estudios cooperativos bien diseñados y mejor comprensión del comportamiento biológico han logrado mejorar la sobrevida global por primera vez en una centuria. El rol de la quimioterapia adyuvante encuentra un escenario cierto, luego de una década de estudios clínicos. El objetivo de este artículo es realizar una revisión de la evidencia disponible que ha colocado a las combinaciones basadas en cisplatino como el tratamiento de elección luego de la cirugía en los estadios II-IIIA del cáncer de pulmón de células no pequeñas.Lung cancer is one of the leading causes of death worldwide. Its incidence is directly related to tobacco use. The patients can be classified in three large groups: those with localized or resectable disease; those with locally advanced disease and lastly those with metastatic disease. Except for anecdotal cases, in the first group cure is possible. For these patients surgery is the treatment of choice. However, with the appearance of effective systemic chemotherapy, well designed cooperative studies and a better understanding of the biological behaviour, overall survival has improved for the first time in a hundred years. The role of adjuvant chemotherapy is a true option after a decade of clinical trials. The objective of this article is to perform a review of the available evidence which has made cisplatin based combinations is the treatment of choice after surgery for stages II-IIIA non-small cell lung cancer.

    Objective To compare the effect of two different exercise program on rehabilitation in breast cancer patients after postoperative adjuvant chemotherapy. Methods A total of 120 breast cancer patients after modified radical mastectomy and 10 to 12 months postoperative adjuvant chemotherapy were randomly divided into two groups. Four-month of music exercises versus aerobic exercises and simplified Tai Ji were provided for the patients in the control group and experimental group,respectively. Results After 4-months exercises,only the patients' elbow flexor strength was significantly improved while the bone mineral density was reduced in the control group (P<0.05). In the experimental group,the patients' limb muscle strength,lung function and body shape were significantly improved (P<0.05),and no significant change in the bone mineral density(P>0.05). Compared with the control group,the patients' vital capacity was significantly higher,while the body mass index(BMI)was significantly lower in the experimental group(P<0.01). No significant difference was found on the quality of life between the two groups (P>0.05). Conclusion Both the two exercise programs can enhance the elbow flexor strength. Tai Ji and aerobic exercise can also promote the restoration of limb function,improve lung function and body shape,and slow bone loss,thus improving the overall rehabilitation outcomes.%目的 比较两种运动方案对乳腺癌患者辅助化疗后康复效果的影响.方法 将行乳腺癌改良根治术且完成术后辅助化疗10~12个月的女性患者120例随机分为两组,进行为期4个月的锻炼,试验组实施太极有氧组合运动,对照组采用传统音乐康复操.结果 锻炼4个月后,试验组在患侧上肢肌力、肺功能和体形方面均较入组时改善(P0.05);对照组患侧上肢肘屈肌力较入组时增强,股骨密度较入组时下降(P0.05).结论 两种运动方案均可增强患侧上肢肘屈肌力;太极有氧组合运动

    There is no clear consensus on what type of adjuvant therapy should be used for patients with pancreatic cancer. Chemoradiation is the favored treatment modality by many in the United States while gemcitabine based chemotherapy is favored in Europe. Both of these approaches have been shown by large prospective, randomized trials to improve disease free intervals and in some studies overall survival.

  4. Failure to Adhere to Protocol Specified Radiation Therapy Guidelines Was Associated With Decreased Survival in RTOG 9704—A Phase III Trial of Adjuvant Chemotherapy and Chemoradiotherapy for Patients With Resected Adenocarcinoma of the Pancreas

    Purpose: In Radiation Therapy Oncology Group 9704, as previously published, patients with resected pancreatic adenocarcinoma received continuous infusion 5-FU and concurrent radiotherapy (5FU-RT). 5FU-RT treatment was preceded and followed by randomly assigned chemotherapy, either 5-FU or gemcitabine. This analysis explored whether failure to adhere to specified RT guidelines influenced survival and/or toxicity. Methods and Materials: RT requirements were protocol specified. Adherence was scored as per protocol (PP) or less than per protocol (< PP). Scoring occurred after therapy but before trial analysis and without knowledge of individual patient treatment outcomes. Scoring was done for all tumor locations and for the subset of pancreatic head location. Results: RT was scored for 416 patients: 216 PP and 200 < PP. For all pancreatic sites (head, body/tail) median survival (MS) for PP vs. < PP was 1.74 vs. 1.46 years (log–rank p = 0.0077). In multivariate analysis, PP vs. < PP score correlated more strongly with MS than assigned treatment arm (p = 0.014, p = NS, respectively); for patients with pancreatic head tumors, both PP score and gemcitabine treatment correlated with improved MS (p = 0.016, p = 0.043, respectively). For all tumor locations, PP score was associated with decreased risk of failure (p = 0.016) and, for gemcitabine patients, a trend toward reduced Grade 4/5 nonhematologic toxicity (p = 0.065). Conclusions: This is the first Phase III, multicenter, adjuvant protocol for pancreatic adenocarcinoma to evaluate the impact of adherence to specified RT protocol guidelines on protocol outcomes. Failure to adhere to specified RT guidelines was associated with reduced survival and, for patients receiving gemcitabine, trend toward increased nonhematologic toxicity.

    2006-01-01

    Metastatic gastric cancer remains a non-curative disease.Palliative chemotherapy has been demonstrated to prolong survival without quality of life compromise. Many single-agents and combinations have been confirmed to be active in the treatment of metastatic disease. Objective response rates ranged from 10-30% for single-agent therapy and 30-60% for polychemotherapy. Results of phase Ⅱ and Ⅲ studies are reviewed in this paper as well as the potential efficacy of new drugs. For patients with localized disease, the role of adjuvant and neoadjuvant chemotherapy and radiation therapy is discussed.Most studies on adjuvant chemotherapy failed to demonstrate a survival advantage, and therefore, it is not considered as standard treatment in most centres. Adjuvant immunochemotherapy has been developed fundamentally in Korea and Japan. A meta-analysis of phase Ⅲ trials with OK-432 suggested that immunochemotherapy may improve survival of patients with curatively resected gastric cancer. Based on the results of US Intergroup 0116study, postoperative chemoradiation has been Accepted as standard care in patients with resected gastric cancer in North America. However, the results are somewhat confounded by the fact that patients underwent less than a recommended D1 lymph node dissection and the pattern of recurrence suggested a positive effect derived from local radiotherapy without any effect on micrometastatic disease.Neoadjuvant chemotherapy or chemoradiation therapy remains experimental, but several phase Ⅱstudies are showing promising results. Phase Ⅲ trials are needed.

    Objective: The aim of this study was to investigate the side effects of docetaxel with cyclophosphamide as postoperative adjuvant chemotherapy for elderly breast cancer patients. Methods: Thirty-six operable elderly breast cancer patients at intermediate risk based on the St Gallen risk classification underwent modified radical mastectomy and then were given four cycles of TC regimen (docetaxe175 mg/m2 i.v. on day 1; cyclophosphamide 600 mg/m2 i.v. on day 1; every 21 days ). Primary prophylaxis granulocyte colony stimulating factor (G-CSF) 200tμg i.h. was administered on day 4-6. Results: The main side effect was neutropenia. Grade 3 neutropenia developed in 36.1% and G4 in 19.4%.respectively. Most of the other side effects were G1-2. Dose reduction occurred in 11.1% patients. The completion rate of chemotherapy was 100%. Conclusion: Docetaxel with cyclophosphamide as postoperative adjuvant chemotherapy regimen with G-CSF primary prophylaxis is tolerable for elderly patients in general good condition.

    In 1996, a multicenter randomized study comparing after breast-conservative surgery. sequential vs concurrent adjuvant chemotherapy (CT) with radiation therapy (RT) was initiated (ARCOSEIN study). Seven hundred sixteen patients were included in this trial. After a median follow-up of 6.7 (4.3 -9) years, we decided to prospectively evaluate the late effects of these two strategies. Patients and methods - A total of 297 patients were asked to follow-up from the five larger including institutions. Seventy-two percent (214 patients) were eligible for late toxicity. After breast-conserving surgery with axillary dissection, patients were treated either with sequential treatment with CT first followed by RT (arm A) or CT administered concurrently with RT (arm B). In all patients, CT regimen combined mitoxantrone (12 mg/m{sup 2}). 5-FU (500 mg/m{sup 2}), and cyclophosphamide (500 mg/m{sup 2}), 6 cycles (day 1-day 21). In arm B, patients received concurrently the first 3 cycles of CT with RT. In arm A, RT started 3 to 5 weeks after the 6. cycle of CT. Conventional RT was delivered to the whole breast using a 2 Gy-fraction protocol to a total dose of 50 Gy ({+-} boost to the primary tumour bed). The assessment of toxicity was blinded to treatment and was graded by the radiation oncologist according to the LENT-SOMA scale. Skin pigmentation was also evaluated using a personal 5-points scoring system (excellent, good, moderate, poor, very poor). Results - Among the 214 evaluated patients, 107 were treated in each arm. The two populations were homogeneous for patients', tumors' and treatment characteristics. Subcutaneous fibrosis (SF), telangiectasia (T), skin pigmentation (SP), and breast atrophy (BA) were significantly increased in arm B. Twenty patients experienced grade superior or equal to 2 (SF) in arm B vs five in arm A (P 0.003). Twenty-five and seven patients showed grade superior or equal to 2 (T) in ann B and A, respectively (P = 0.001). Forty-four and

    CyberKnife allows the performance of stereotactic radiotherapy of thorax tumours with accuracy and with a real time target tracking system. The authors aimed at demonstrating the interest of this system for the treatment of breast cancers. They report a phase I study of dose escalation. A neo-adjuvant based chemotherapy is associated with the irradiation. Breast surgery is performed six to eight weeks after the sixth chemotherapy session cycle. The aim was to determine the maximum tolerated dose for the hypo-fractionated radiotherapy. Cutaneous toxicity is the limiting factor. 25 patients have been treated with different dose levels (from 18,5 to 31,5 Gy). Results are promising and must be confirmed, notably through a randomized multicentre phase II study. Short communication

  15. Hyperthermia and chemotherapy agent

    The use of chemotherapeutic agents for the treatment of cancer dates back to the late 19th century, but the modern era of chemotherapy drugs was ushered in during the 1940's with the development of the polyfunctional alkylating agent. Since then, numerous classes of drugs have evolved and the combined use of antineoplastic agents with other treatment modalities such as radiation or heat, remains a large relatively unexplored area. This approach, combining local hyperthermia with chemotherapy agents affords a measure of targeting and selective toxicity not previously available for drugs. In this paper, the effects of adriamycin, bleomycin and cis-platinum are examined. The adjuvant use of heat may also reverse the resistance of hypoxic cells noted for some chemotherapy agents

    The discrepancy between the surgical technique and the type of adjuvant chemotherapy used in clinical trials and patient outcomes in terms of overall survival rates has led to the generation of different adjuvant treatment protocols in distinct parts of the world. The adjuvant treatment recommendation is generally chemoradiotherapy in the United States, perioperative chemotherapy in the United Kingdom and parts of Europe, and chemotherapy in Asia. These options mainly rely on the United States Intergroup-0116, United Kingdom British Medical Research Council Adjuvant Gastric Infusional Chemotherapy, and the Asian Adjuvant Chemotherapy Trial of S-1 for Gastric Cancer and Capecitabine and Oxaliplatin Adjuvant Study in Stomach Cancer trials. However, the benefits were evident for only certain patients, which were not very homogeneous regarding the type of surgery, chemotherapy regimens, and stage of disease. Whether the dissimilarities in survival are attributable to surgical technique or intrinsic biological differences is a subject of debate. Regardless of the extent of surgery, multimodal therapy may offer modest survival advantage at least for diseases with lymph node involvement. Moreover, in the era of individualized treatment for most of the other cancer types, identification of special subgroups comprising those who will derive more or no benefit from adjuvant therapy merits further investigation. The aim of this review is to reveal the historical evolution and future reflections of adjuvant treatment modalities for resected gastric cancer patients. PMID:27190583

  3. Adjuvant therapy for ampullary carcinomas: The Mayo Clinic experience

    Purpose: To determine the effects of adjuvant radiotherapy and chemotherapy for carcinoma of the ampulla of Vater. Methods and Materials: We retrospectively reviewed the records of 125 patients who underwent definitive surgery for carcinomas involving the ampulla of Vater between April 1977 and February 2005 and who survived more than 50 days after surgery. Twenty-nine of the patients also received adjuvant radiotherapy (median dose, 50.4 Gy in 28 fractions) with concurrent 5-fluorouracil chemotherapy. Adverse prognostic factors were investigated, and overall survival (OS) and local and distant failure were estimated. Results: Adverse prognostic factors for decreased OS by univariate analysis included lymph node (LN) involvement, locally advanced tumors (T3/T4), and poor histologic grade. By multivariate analysis, positive LN status (p = 0.02) alone was associated with decreased OS. The addition of adjuvant radiotherapy and chemotherapy improved OS for patients with positive LN (p = 0.01). Median survival for positive LN patients receiving adjuvant therapy was 3.4 years, vs. 1.6 years for those with surgery alone. Conclusions: The addition of adjuvant radiotherapy and 5-fluorouracil chemotherapy may improve OS in patients with LN involvement. The effect of adjuvant therapy on outcomes for patients with poor histologic grade or T3/T4 tumors without LN involvement could not be assessed

    2009-01-01

    Objective: The aim of the study was to investigate the prospective study if treatment with arsenic trioxide (As2O3) could enhance disease-free survival as adjuvant post-operative chemotherapy for gastric cancer patients and protect bone marrow from the negative effects of chemotherapy. Methods: 84 adults were randomized into two groups. Patients in treat- ment group were treated with As203 and FOLFOX regimen, the other were administered with FOLFOX regimen only. Results: Four patients were withdrawn in treatment group after 3-4 cycles and the reasons were headache and fidgety (n = 2), ar- rhythmia (n = 1) and AST/ALT elevation (n = 1), while 1 patient in control group after 4 cycles for neutropenia. In the treatment group, the median DFS was 28.34 months (95% CI, 25-33 months). While in control group, the median DFS was 24.50 months (95% CI, 20-30 months). This difference was not statistically significant (chi-square: 2.8885; P value: 0.0892). Pa- tients in the same subgroup of node-positive was 29 in the treatment group and 32 in control group, respectively. The median DFS was 27.87 months (95% CI, 25-31 months) in the treatment group and 24.18 months (95% CI, 19-31 months) in the control group with promising statistical significance (HR 1.89; chi-square: 4.78; P value: 0.0287). The most common grades 3-4 toxicity was leucopenia (n = 11) in control group and the difference was significant (chi-square: 3.9768, P value: 0.046) compared with that in treatment group (n = 4). Conclusion: The combination of arsenic trioxide and FOLFOX regimen has a potential advantage of enhancing disease-free survival in patients with gastric cancer in nodal-positive status as post-opera- tive chemotherapy, and protect bone marrow from the negative effects of chemotherapy.

  10. Second malignancies after breast cancer: The impact of adjuvant therapy

    Dong, Chunhui; Chen, Ling

    2014-01-01

    Second malignant neoplasms (SMNs) are potentially life-threatening late sequelae of the adjuvant therapy for breast cancer (BC). The increased risk of SMNs is associated with adjuvant chemotherapy (development of secondary acute myeloid leukemia and myelodysplastic syndrome) and hormonal therapy (risk of uterine cancer secondary to tamoxifen treatment). Previous studies have demonstrated an increased risk of SMNs associated with alkylating agents, topoisomerase-II inhibitors, granulocyte-stim...

    Pancreatic adenocarcinoma is one of the most aggressive human malignancies,ranking 4th among causes for cancer-related death in the Western world including the United States.Surgical resection offers the only chance of cure,but only 15 to 20 percent of cases are potentially resectable at presentation.Different studies demonstrate and confirm that advanced pancreatic cancer is among the most complex cancers to treat and that these tumors are relatively resistant to chemotherapy and radiotherapy.Currently there is no consensus around the world on what constitutes "standard"adjuvant therapy for pancreatic cancer.This controversy derives from several studies,each fraught with its own limitations.Standards of care also vary somewhat with regard to geography and economy,for instance chemo-radiotherapy followed by chemotherapy or vice versa is considered the optimal therapy in North America while chemotherapy alone is the current standard in Europe.Regardless of the efforts in adjuvant and neoadjuvant improved therapy,the major goal to combat pancreatic cancer is to find diagnostic markers,identifying the disease in a pre-metastatic stage and making a curative treatment accessible to more patients.In this review,authors examined the different therapy options for advanced pancreatic patients in recent years and the future directions in adjuvant and neoadjuvant treatments for these patients.

  14. Systemic adjuvant therapies in renal cell carcinoma.

    Buti, Sebastiano; Bersanelli, Melissa; Donini, Maddalena; Ardizzoni, Andrea

    2012-10-01

    Renal cell carcinoma (RCC) is one of the ten most frequent solid tumors worldwide. Recent innovations in the treatment of metastatic disease have led to new therapeutic approaches being investigated in the adjuvant setting. Observation is the only current standard of care after radical nephrectomy, although there is evidence of efficacy of adjuvant use of vaccine among all the strategies used. This article aims to collect published experiences with systemic adjuvant approaches in RCC and to describe the results of past and ongoing phase III clinical trials in this field. We explored all the systemic treatments, including chemotherapy, immunotherapy and targeted drugs while alternative approaches have also been described. Appropriate selection of patients who would benefit from adjuvant therapies remains a crucial dilemma. Although the international guidelines do not actually recommend any adjuvant treatment after radical surgery for RCC, no conclusions have yet been drawn pending the results of the promising ongoing clinical trials with the target therapies. The significant changes that these new drugs have made on advanced disease outcome could represent the key to innovation in terms of preventing recurrence, delaying relapse and prolonging survival after radical surgery for RCC.

    2007-07-01

    Androgen deprivation in patients with metastatic prostate cancer produces palliation of symptoms, PSA decrease and tumoral regression in most patients. After a brief period of disease regression lasting 18 to 24 months nearly all pts will progress to androgen independence disease (HRPC) with progressive clinical deterioration and ultimately death. Chemotherapy with mitoxantrone has been shown to palliate symptoms but did not extend survival. Two large randomized trials showed a survival benefit for pts with HRPC treated with docetaxel with a reduction risk of death by 21-24%, and significant improvement in palliation of symptoms and quality of life. New agents targeting angiogenesis, apoptosis, signal transduction pathway, used alone or in combination with docetaxel currently are under trial in an attempt to provide much needed improvements in outcome. Questions remains in suspend when and who need to be treated, earlier, in high risk as in adjuvant setting? Current data have demonstrated that neoadjuvant or adjuvant chemotherapy is relatively safe and feasible. Further investigation through prospective randomize trials is critical to define the precise role of this modality in high risk populations. PMID:17845990

    2012-01-01

    Full Text Available Breast cancer is the most frequent neoplasm affecting women worldwide. Some of the recommended treatments involve chemotherapy whose toxic effects include leukopenia and neutropenia. This study assessed the effectiveness of Uncaria tomentosa (Ut in reducing the adverse effects of chemotherapy through a randomized clinical trial. Patients with Invasive Ductal Carcinoma—Stage II, who underwent a treatment regimen known as FAC (Fluorouracil, Doxorubicin, Cyclophosphamide, were divided into two groups: the UtCa received chemotherapy plus 300 mg dry Ut extract per day and the Ca group that only received chemotherapy and served as the control experiment. Blood samples were collected before each one of the six chemotherapy cycles and blood counts, immunological parameters, antioxidant enzymes, and oxidative stress were analyzed. Uncaria tomentosa reduced the neutropenia caused by chemotherapy and was also able to restore cellular DNA damage. We concluded that Ut is an effective adjuvant treatment for breast cancer.

    In pre-clinical models, the only two chemotherapy drugs which have been demonstrated to directly reduce the number of myeloid-derived suppressor cells (MDSCs) are gemcitabine and 5-fluorouracil. Here we analyze the dynamics of MDSCs, phenotyped as Lin-DR-CD11b+, in patients with advanced pancreatic cancer receiving the combination of gemcitabine and capecitabine, a 5-FU pro-drug. We found no evidence that gemcitabine and capecitabine directly reduce MDSC% in patients. Gemcitabine and capecita...

    2010-01-01

    Taxanes (paclitaxel and docetaxel) are currently considered to be basic cytostatics in the treatment of all breast cancer (BC) stages. The results of conducted and ongoing clinical trials suggest that incorporation of taxanes into adjuvant and neoadjuvant chemotherapy regimens enhances the efficiency of treatment for operable BC and show it necessary to apply an individual approach depending on prognostic and predictive factors.

  2. Phase III Multi-Institutional Trial of Adjuvant Chemotherapy With Paclitaxel, Estramustine, and Oral Etoposide Combined With Long-Term Androgen Suppression Therapy and Radiotherapy Versus Long-Term Androgen Suppression Plus Radiotherapy Alone for High-Risk Prostate Cancer: Preliminary Toxicity Analysis of RTOG 99-02

    Purpose: Long-term androgen suppression plus radiotherapy (AS+RT) is standard treatment of high-risk prostate cancer. A randomized trial, Radiation Therapy Oncology Group trial 9902, was undertaken to determine whether adjuvant chemotherapy with paclitaxel, estramustine, and etoposide (TEE) plus AS+RT would improve disease outcomes with acceptable toxicity. Methods and Materials: High-risk (prostate-specific antigen 20-100 ng/mL and Gleason score ≥7; or Stage T2 or greater, Gleason score 8, prostate-specific antigen level <100 ng/mL) nonmetastatic prostate cancer patients were randomized to AS+RT (Arm 1) vs. AS+RT plus four cycles of TEE (Arm 2). TEE was delivered 4 weeks after RT. AS continued for 2 years for both treatment arms. RT began after 8 weeks of AS began. Results: The Radiation Therapy Oncology Group 9902 trial opened January 11, 2000. Excess thromboembolic toxicity was noted, leading to study closure October 4, 2004. A total of 397 patients were accrued, and the data for 381 were analyzable. An acute and long-term toxicity analysis was performed. The worst overall toxicities during treatment were increased for Arm 2. Of the 192 patients, 136 (71%) on Arm 2 had RTOG Grade 3 or greater toxicity compared with 70 (37%) of 189 patients on Arm 1. Statistically significant increases in hematologic toxicity (p < 0.0001) and gastrointestinal toxicity (p = 0.017) but not genitourinary toxicity (p = 0.07) were noted during treatment. Two Grade 5 complications related to neutropenic infection occurred in Arm 2. Three cases of myelodysplasia/acute myelogenous leukemia were noted in Arm 2. At 2 and 3 years after therapy completion, excess long-term toxicity was not observed in Arm 2. Conclusion: TEE was associated with significantly increased toxicity during treatment. The toxicity profiles did not differ at 2 and 3 years after therapy. Toxicity is an important consideration in the design of trials using adjuvant chemotherapy for prostate cancer

    The efficacy of neoadjuvant chemotherapy and adjuvant chemotherapy on stage lib nasopharyngeal carcinoma(NPC) remains unclear.Conventional two-dimensional radiotherapy combined with concurrent chemotherapy can improve the overall survival,progression-free survival,recurrence-free survival,and distant metastasis-free survival of patients with stage lib NPC.Intensity-modulated radiotherapy without concurrent chemotherapy also provides good outcomes for patients with stage lib NPC.This article summarizes the features of stage lib NPC and reviews the role of chemotherapy in this subgroup of NPC.

  4. A Phase 3 Trial of 2 Years of Androgen Suppression and Radiation Therapy With or Without Adjuvant Chemotherapy for High-Risk Prostate Cancer: Final Results of Radiation Therapy Oncology Group Phase 3 Randomized Trial NRG Oncology RTOG 9902

    Purpose: Long-term (LT) androgen suppression (AS) with radiation therapy (RT) is a standard treatment of high-risk, localized prostate cancer (PCa). Radiation Therapy Oncology Group 9902 was a randomized trial testing the hypothesis that adjuvant combination chemotherapy (CT) with paclitaxel, estramustine, and oral etoposide plus LT AS plus RT would improve overall survival (OS). Methods and Materials: Patients with high-risk PCa (prostate-specific antigen 20-100 ng/mL and Gleason score [GS] ≥7 or clinical stage ≥T2 and GS ≥8) were randomized to RT and AS (AS + RT) alone or with adjuvant CT (AS + RT + CT). CT was given as four 21-day cycles, delivered beginning 28 days after 70.2 Gy of RT. AS was given as luteinizing hormone-releasing hormone for 24 months, beginning 2 months before RT plus an oral antiandrogen for 4 months before and during RT. The study was designed based on a 6% improvement in OS from 79% to 85% at 5 years, with 90% power and a 2-sided alpha of 0.05. Results: A total of 397 patients (380 eligible) were randomized. The patients had high-risk PCa, 68% with GS 8 to 10 and 34% T3 to T4 tumors, and median prostate-specific antigen of 22.6 ng/mL. The median follow-up period was 9.2 years. The trial closed early because of excess thromboembolic toxicity in the CT arm. The 10-year results for all randomized patients revealed no significant difference between the AS + RT and AS + RT + CT arms in OS (65% vs 63%; P=.81), biochemical failure (58% vs 54%; P=.82), local progression (11% vs 7%; P=.09), distant metastases (16% vs 14%; P=.42), or disease-free survival (22% vs 26%; P=.61). Conclusions: NRG Oncology RTOG 9902 showed no significant differences in OS, biochemical failure, local progression, distant metastases, or disease-free survival with the addition of adjuvant CT to LT AS + RT. The trial results provide valuable data regarding the natural history of high-risk PCa treated with LT AS + RT and have implications for

    Purpose: Long-term (LT) androgen suppression (AS) with radiation therapy (RT) is a standard treatment of high-risk, localized prostate cancer (PCa). Radiation Therapy Oncology Group 9902 was a randomized trial testing the hypothesis that adjuvant combination chemotherapy (CT) with paclitaxel, estramustine, and oral etoposide plus LT AS plus RT would improve overall survival (OS). Methods and Materials: Patients with high-risk PCa (prostate-specific antigen 20-100 ng/mL and Gleason score [GS] ≥7 or clinical stage ≥T2 and GS ≥8) were randomized to RT and AS (AS + RT) alone or with adjuvant CT (AS + RT + CT). CT was given as four 21-day cycles, delivered beginning 28 days after 70.2 Gy of RT. AS was given as luteinizing hormone-releasing hormone for 24 months, beginning 2 months before RT plus an oral antiandrogen for 4 months before and during RT. The study was designed based on a 6% improvement in OS from 79% to 85% at 5 years, with 90% power and a 2-sided alpha of 0.05. Results: A total of 397 patients (380 eligible) were randomized. The patients had high-risk PCa, 68% with GS 8 to 10 and 34% T3 to T4 tumors, and median prostate-specific antigen of 22.6 ng/mL. The median follow-up period was 9.2 years. The trial closed early because of excess thromboembolic toxicity in the CT arm. The 10-year results for all randomized patients revealed no significant difference between the AS + RT and AS + RT + CT arms in OS (65% vs 63%; P=.81), biochemical failure (58% vs 54%; P=.82), local progression (11% vs 7%; P=.09), distant metastases (16% vs 14%; P=.42), or disease-free survival (22% vs 26%; P=.61). Conclusions: NRG Oncology RTOG 9902 showed no significant differences in OS, biochemical failure, local progression, distant metastases, or disease-free survival with the addition of adjuvant CT to LT AS + RT. The trial results provide valuable data regarding the natural history of high-risk PCa treated with LT AS + RT and have implications for

  6. [Influenza vaccine and adjuvant].

    Nakayama, Tetsuo

    Adjuvant is originated from the Latin word "adjuvare" which means "help" in English to enhance the immunological responses when given together with antigens. The beginning of adjuvant was mineral oil which enhanced the immune response when it was given with inactivated Salmonella typhimurium. Aluminium salt was used to precipitate diphtheria toxoid and increased level of antibody response was demonstrated when administered with alum-precipitated antigens. Since 1930, aluminium salt has been used as DTaP (diphtheria-tetanus-acellular pertussis vaccine) adjuvant. Many candidates were tested for adjuvant activity but only aluminum salt is allowed to use for human vaccines. New adjuvant MF59, oil-in-water emulsion type, was developed for influenza vaccine for elderly (Fluad) and series of AS adjuvant are used for hepatitis B, pandemic flue, and human papiloma virus vaccines. Oil-adjuvanted influenza pandemic vaccines induced higher antibody response than alum-adjuvanted vaccine with higher incidence of adverse events, especially for local reactions. Alum-adjuvanted whole virion inactivated H5N1 vaccine was developed in Japan, and it induced relatively well immune responses in adults. When it applied for children, febrile reaction was noted in approximately 60% of the subjects, with higher antibodies. Recent investigation on innate immunity demonstrates that adjuvant activity is initiated from the stimulation on innate immunity and/or inflammasome, resulting in cytokine induction and antigen uptake by monocytes and macrophages. The probable reason for high incidence of febrile reaction should be investigated to develop a safe and effective influenza vaccine. PMID:22129866

  7. The results of a single center pilot study of combined high-dose methotrexate and doxorubicin with cisplatin in neo-adjuvant chemotherapy for osteosarcoma in children and adolescents

    The study summarizes the treatment results of a newly introduced protocol for high-grade osteosarcoma, combining high dose of methotrexate alternating with doxorubicin and cisplatin. The efficacy of preoperative chemotherapy, evaluated as a proportion of necrotic cells assessed in a primary tumor map, was compared with results achieved in historical studies comprising two modalities: doxorubicin and high dose of methotrexate (the so called SFOPprotocol) or doxorubicin and cisplatin (the so-called EORT protocol) only. Additionally, we performed a comparative analysis of early toxicity of all the three protocols. Apart from statistically insignificant differences between the results of all the three protocols, we have demonstrated that the efficacy of the currently introduces protocol exceeds that of the SFOP protocol and is comparable to the EORTC protocol (48.5% vs. 44% and 49%, respectively), with only two cycles of cardiotoxic doxorubicin applied in the current protocol. The proportion of limb saving procedures in the current protocol (82%>) was comparable to SFOP (85%) and exceeded that achieved in the EORTC protocol (48%). Progression of tumor mass was observed in 4% of patients treated according to the EORTC protocol, in 10% of currently assessed patients and in 44% of patients treated according to the SFOP protocol. Acute toxicity of cytostatics requiring withholding ongoing chemotherapy was considerably less common in the SFOP group (36%), when compared to current protocol (2.5%) and the EORTC protocol (0%). The results of this pilot study demonstrate the comparable or even higher efficacy and safety of the currently introduced protocol as compared to the historical treatment protocols in patients with high-grade osteosarcoma. The comprehensive results of the study and the final assessment of the safety and the efficacy of the currently introduced protocol calls for a long observation period and a larger patient group.

  8. Anticancer chemotherapy

    Weller, R.E.

    1988-10-01

    Despite troubled beginnings, anticancer chemotherapy has made significant contribution to the control of cancer in man, particularly within the last two decades. Early conceptual observations awakened the scientific community to the potentials of cancer chemotherapy. There are now more than 50 agents that are active in causing regression of clinical cancer. Chemotherapy's major conceptual contributions are two-fold. First, there is now proof that patients with overt metastatic disease can be cured, and second, to provide a strategy for control of occult metastases. In man, chemotherapy has resulted in normal life expectancy for some patients who have several types of metastatic cancers, including choriocarcinoma, Burkitt's lymphomas, Wilm's tumor, acute lymphocytic leukemia, Hodgkins disease, diffuse histiocytic lymphoma and others. Anticancer chemotherapy in Veterinary medicine has evolved from the use of single agents, which produce only limited remissions, to the concept of combination chemotherapy. Three basic principles underline the design of combination chemotherapy protocols; the fraction of tumor cell killed by one drug is independent of the fraction killed by another drug; drugs with different mechanisms of action should be chosen so that the antitumor effects will be additive; and since different classes of drugs have different toxicities the toxic effects will not be additive.

    For early stage breast cancer, wide local excision and post-operative whole breast irradiation is a standard treatment. If adjuvant chemotherapy is recommended, radiation is usually given after completion of chemotherapy. In recent years, accelerated partial breast irradiation (APBI) with balloon-cathetered based brachytherapy has become an option for selected patients. For these patients, adjuvant chemotherapy would have to be administered after radiation. The sequence of treatment with radiation followed by chemotherapy results in increased risk of radiation recall reaction (RRD) in these patients. Docetaxel is becoming a more commonly used drug as adjuvant treatment for breast cancer. Here we report a case of docetaxel induced RRD after APBI with balloon-cathetered based brachytherapy. Such reaction would have an adverse impact on the cosmetic outcome and quality of life of the patient. For patients who develop an intense skin reaction after the administration of docetaxel following APBI, RRD should be considered in the differential diagnosis.

  12. Who Benefits From Adjuvant Radiation Therapy for Gastric Cancer? A Meta-Analysis

    Purpose: Large randomized trials have demonstrated significant survival benefits with the use of adjuvant chemotherapy or chemoradiation therapy for gastric cancer. The importance of adjuvant radiation therapy (RT) remains unclear. We performed an up-to-date meta-analysis of randomized trials testing the use of RT for resectable gastric cancer. Methods and Materials: We searched MEDLINE, EMBASE, and the Cochrane Central Register of Controlled Trials for randomized trials testing adjuvant (including neoadjuvant) RT for resectable gastric cancer. Hazard ratios describing the impact of adjuvant RT on overall survival (OS) and disease-free survival (DFS) were extracted directly from the original studies or calculated from survival curves. Pooled estimates were obtained using the inverse variance method. Subgroup analyses were performed to determine whether the efficacy of RT varies with chemotherapy use, RT timing, geographic region, type of nodal dissection performed, or lymph node status. Results: Thirteen studies met all inclusion criteria and were used for this analysis. Adjuvant RT was associated with a significant improvement in both OS (HR = 0.78, 95% CI: 0.70-0.86, P<.001) and DFS (HR = 0.71, 95% CI: 0.63-0.80, P<.001). In the 5 studies that tested adjuvant chemoradiation therapy against adjuvant chemotherapy, similar effects were seen for OS (HR = 0.83, 95% CI: 0.67-1.03, P=.087) and DFS (HR = 0.77, 95% CI: 0.91-0.65, P=.002). Available data did not reveal any subgroup of patients that does not benefit from adjuvant RT. Conclusion: In randomized trials for resectable gastric cancer, adjuvant RT provides an approximately 20% improvement in both DFS and OS. Available data do not reveal a subgroup of patients that does not benefit from adjuvant RT. Further study is required to optimize the implementation of adjuvant RT for gastric cancer with regard to patient selection and integration with systemic therapy

    It has been demonstrated that 1,25-dihydroxyvitamin D3 (1,25D) and some of its analogues have antitumor activity. 1,25D labeled with deuterium (26,26,26,27,27,27-hexadeuterated 1α,25-dihydroxyvitamin D3, or 1,25D-d6) is commonly used as internal standard for 1,25D liquid chromatography-mass spectrometry (LC-MS) quantification. In the present study using human breast cancer cell lines, the biological activity of 1,25D-d6 administered alone and in combination with two commonly used antineoplastic agents, 5-fluorouracil and etoposide, was evaluated. Using an MTT assay, flow cytometry, and western blots, our data demonstrated that 1,25D-d6 has effects similar to the natural hormone on cell proliferation, cell cycle, and apoptosis. Furthermore, the combination of 1,25D-d6 and etoposide enhances the antitumoral effects of both compounds. Interestingly, the antitumoral effect is higher in the more aggressive MDA-MB-231 breast cancer cell line. Our data indicate that 1,25D-d6 administered alone or in combination with chemotherapy could be a good experimental method for accurately quantifying active 1,25D levels in cultures or in biological fluids, on both in vitro breast cancer cell lines and in vivo animal experimental models

    Low vitamin D levels have been associated with poor breast cancer outcomes in observational studies. We examined the association of vitamin D blood levels with relapse-free survival (RFS), breast cancer-specific survival (BCSS), and overall survival (OS) in the MA.21 randomized clinical trial. Fasting blood was collected pre-chemotherapy in 934/2104 (44.4 %) of subjects; 25 hydroxy vitamin D was measured (radioimmunoassay, Diasorin) in one batch. Vitamin D was assessed as a transformed continuous factor, and categorically (quartiles and clinical classifications). Univariate and multivariate prognostic analyses (adjusted for treatment, stratification factors, and baseline imbalances) were performed using Cox models. Most patients were young (median 47.8 years), white (91.6 %) and premenopausal (69.4 %) with grade III (52 %), HER2 negative or missing (89.5 %), ER positive (61.9 %), T1-2 (89.4 %), N + (72.7 %) breast cancer. Compared to the full population, those with vitamin D levels were more likely to be white, PS 1 or 2, to have undergone mastectomy, and to have an ER + tumor. Mean vitamin D was 69.7 nmol/L (27.9 ng/ml) and did not vary by tumor subtype. The majority (80.5 %) had levels >50 nmol/L (20 ng/ml), considered adequate by Institute of Medicine. Continuous vitamin D was not multivariately associated with RFS, BCSS, or OS (p = 0.36, 0.26, 0.33, respectively); categorical vitamin D was also not associated with outcome. Vitamin D associations with RFS did not differ within ER/HER2 subgroups. There was no evidence that vitamin D blood level was associated with RFS, BCSS, and OS in MA.21; the majority of subjects had adequate vitamin D levels at study entry. PMID:25833209

  17. Impact of adjuvant therapy on survival of patients with early-stage uterine papillary serous carcinoma

    Purpose: To determine the efficacy of adjuvant therapy in patients with early-stage uterine papillary serous carcinoma. Methods and Materials: Data were collected on all surgically staged Stage I-II uterine papillary serous carcinoma patients. Statistical analyses were performed using the Kaplan-Meier and Cox proportional hazards regression methods. Results: Of 68 patients, 50 had Stage I and 18 had Stage II disease; 35 underwent adjuvant treatment, including radiotherapy in 26, chemotherapy in 7, and combined RT and chemotherapy in 2. The remaining 33 were treated expectantly. The median follow-up was 56 months (range 1-173). The 5-year overall survival rate was 69%. Of 19 patients with disease limited to the endometrium, 10 received no additional therapy, 3 of whom developed recurrence. However, all 9 women who underwent adjuvant treatment remained free of disease. Patients receiving adjuvant therapy with chemotherapy or radiotherapy had a prolonged 5-year overall and disease-free survival compared with those who were treated expectantly (85% vs. 54%, p = 0.002 for overall survival and 85% vs. 49%, p 0.01 for disease-free survival). In multivariate analysis, adjuvant therapy (p = 0.035) and the absence of lymphovascular space invasion (p = 0.001) remained as independent prognostic factors for improved survival. Conclusion: Adjuvant therapy with chemotherapy or radiotherapy improves the survival of women with early-stage uterine papillary serous carcinoma

  18. Retinoblastoma: Achieving new standards with methods of chemotherapy

    Swathi Kaliki

    Full Text Available The management of retinoblastoma (RB has dramatically changed over the past two decades from previous radiotherapy methods to current chemotherapy strategies. RB is a remarkably chemotherapy-sensitive tumor. Chemotherapy is currently used as a first-line approach for children with this malignancy and can be delivered by intravenous, intra-arterial, periocular, and intravitreal routes. The choice of route for chemotherapy administration depends upon the tumor laterality and tumor staging. Intravenous chemotherapy (IVC is used most often in bilateral cases, orbital RB, and as an adjuvant treatment in high-risk RB. Intra-arterial chemotherapy (IAC is used in cases with group C or D RB and selected cases of group E tumor. Periocular chemotherapy is used as an adjunct treatment in eyes with group D and E RB and those with persistent/recurrent vitreous seeds. Intravitreal chemotherapy is reserved for eyes with persistent/recurrent vitreous seeds. In this review, we describe the various forms of chemotherapy used in the management of RB. A database search was performed on PubMed, using the terms "RB," and "treatment," "chemotherapy," "systemic chemotherapy," "IVC," "IAC," "periocular chemotherapy," or "intravitreal chemotherapy." Relevant English language articles were extracted, reviewed, and referenced appropriately.

  19. Adjuvant therapy for pancreas cancer in an era of value based cancer care

    Ahn, Daniel H.; Williams, Terence M.; Goldstein, Daniel A.; El-Rayes, Bassel; Bekaii-Saab, Tanios

    2016-01-01

    In resected pancreas cancer, adjuvant therapy improves outcomes and is considered the standard of care for patients who recover sufficiently post operatively. Chemotherapy or combined chemotherapy and radiation therapy (chemoradiation; CRT) are strategies used in the adjuvant setting. However, there is a lack of evidence to suggest whether the addition of RT to chemotherapy translates to an improvement in clinical outcomes. This is true even when accounting for the subset of patients with a higher risk for recurrence, such as those with R1 and lymph node positive disease. When considering the direct and indirect costs, impact on quality of life and questionable added clinical benefit, the true “net health benefit” from added RT to chemotherapy becomes more uncertain. Future directions, including the utilization of modern RT, integration of novel therapies, and intensifying chemotherapy regimens may improve outcomes in resected pancreas cancer. PMID:26620819

    The main methods of treatment for cervical cancer are surgery, radiotherapy or their combination. During past two decades chemotherapy are increasingly being used not only in patients with disseminated forms of this disease but also in patients undergoing chemoradiotherapy or as induction therapy. Possibilities of adjuvant chemotherapy for cervical cancer are being studied. According to A.D.Kaprin and V.V. Starinskiy in 2013 in Russia, 32% of patients with newly diagnosed cervical cancer underwent only radiation therapy, 32%--combined or complex treatment, 27.3%--only surgery, and just 8.7%--chemoradiotherapy.

    The authors reviewed 24 cerebellar medulloblastoma patients treated at Keio University to determine usefulness of combined chemotherapy including platinum derivatives (cisplatin, carboplatin) as the induction and maintenance treatment. All patients underwent radical surgery and craniospinal irradiation. Ten received adjuvant chemotherapy other than platinum derivatives (mainly with nitrosourea compounds), five were treated by induction and maintenance chemotherapy including platinum derivatives, and nine patients did not undergo chemotherapy. The progression-free survival rate of patients treated with platinum derivatives was better than that of patients treated with other modes of chemotherapy and also that of patients who did not receive chemotherapy. The results were especially good in the case of four patients treated with maintenance chemotherapy consisting of carboplatin and etoposide, two of whom had been free from relapse beyond the risk period of Collins. The occurrences of toxicity in maintenance chemotherapy with carboplatin and etoposide were limited to transient leucopenia. The present study indicates combined chemotherapy including platinum derivatives benefits patients with medulloblastoma, and could be useful, especially as maintenance treatment. (author)

  5. Combining chemotherapy with radiation in breast cancer

    Breast cancer is one of the most important global health problems. Over the last years introduction of mammography screening and increased efficacy of adjuvant therapies resulted in the reduction of mortality in this malignancy. A proportion of patients with breast cancer has indications for adjuvant radiotherapy and chemotherapy, however optimal schedules of combining these two modalities remain controversial. In clinical practice typically chemotherapy and radiotherapy are used sequentially, but this strategy is not supported by the results of large clinical trials. There is theoretical rationale for the concomitant use of both modalities, but increased cardiotoxicity and skin reactions of anthracycline-based regimens do not allow for this strategy. Further investigations are essential to determine the safety of taxane-based schedules combined with radiotherapy, particularly with regard to pneumotoxicity. Concurrent chemo-radiotherapy with the use of selected schemes may be considered in patients with locally advanced cancer, but this strategy still should be verified in large randomized studies.

  6. Predicting response to chemotherapy with early-stage lung cancer.

    Rosell, Rafael; Taron, Miquel; Massuti, Bartomeu; Mederos, Nuria; Magri, Ignacio; Santarpia, Mariacarmela; Sanchez, Jose Miguel

    2011-01-01

    A recent meta-analysis of 11,107 patients with non-small cell lung cancer who had undergone surgical resection showed that the 5-year survival benefit of adjuvant chemotherapy was 4%, and that of adjuvant chemoradiotherapy was 5%. Two trials have shown a trend toward improved survival with adjuvant paclitaxel plus carboplatin. However, the benefit of adjuvant treatment remains suboptimal. We must distinguish between patients who will not relapse-and who can thus be spared adjuvant treatment-and those who will-for whom adjuvant treatment must be personalized. Several gene expression signatures, generally containing nonoverlapping genes, provide similar predictive information on clinical outcome, and a model combining several signatures did not perform better than did each of the signatures separately. The invasiveness gene signature, containing 186 genes, includes genes involved in the nuclear factor κB pathway, the RAS-mitogen-activated protein kinase pathway, and epigenetic control of gene expression. A 15-gene signature has identified JBR.10 patients who are more sensitive to adjuvant chemotherapy. PMID:21263267

    Full Text Available There is no universally accepted standard approach to treat patients with pancreatic cancer in the adjuvant setting. This controversy derives from several studies, each fraught with its own limitations. Standards of care also vary depending on which side of the Atlantic you are on: chemo-radiotherapy followed by chemotherapy is considered the optimal therapy in North America (GITSG, RTOG while chemotherapy alone is the current standard in Europe (ESPAC-1, CONKO. Whether gemcitabine is superior to 5-FU remains to be learnt from the ESPAC-3 study currently on-going in Europe. A number of important questions have yet to be fully addressed: • What is the absolute value of radiotherapy in this setting? • How should radiotherapy be delivered, if at all? • What should be the time to deliver of either or both therapeutic modalities in the adjuvant setting? • Are there any patients who can benefit from the combined modality? • What is the most appropriate chemotherapeutic agent(s to administer in the adjuvant setting? • Is there any role of integrating the novel/targeted agents, albeit the negative studies in the metastatic setting? • What are the new developments (such as vaccines, pancreas cancer stem cells, etc. in this area? The author summarizes the evolution of adjuvant therapy for resected pancreatic cancer and highlights the controversies that originate from several studies, each fraught with its own limitations.

  10. Present situation and development of chemotherapy of nasopharyngeal carcinoma%鼻咽癌化疗现状及进展

    2013-01-01

    Chemotherapy is one of main treatments for nasopharyngeal carcinoma (NPC) except radiation therapy. Improving and optimizing chemotherapeutic regimen are helpful to improve the therapeutic effects and reduce side effects. At present, concurrent chemoradiotherapy still is the standard treatment for advanced nasopharyngeal carcinoma. Induced chemotherapy has been shown superiority, but the effect of adjuvant chemotherapy needs further study. This paper analyzed the superior and inferior, effect and side effect of all kinds of chemotherapeutic methods or scheme including induced chemotherapy,concurrent chemotherapy, adjuvant chemotherapy and palliative chemotherapy and introduced simply the mechanism and clinical effect of new drugs of anticancer. It was hoped to offer some reference for the selection of chemotherapy for NPC.

  12. Usefulness of concurrent chemotherapy and radiotherapy of head and neck cancer

    The usefulness of concurrent chemotherapy and radiotherapy in head and neck cancer was reviewed based on the results of randomized comparative trials. First, the schedules of chemotherapy and radiotherapy were assessed. Chemotherapy was classified into 4 categories according to the schedules: neo-adjuvant chemotherapy, concurrent chemotherapy, alternating chemotherapy, and adjuvant chemotherapy. Each schedules has its own purpose, e.g., tumor reduction, prevention of remote metastasis, and radiosensitizing effect. The most important purpose is the improvement of long-term outcome. Meta-analysis by Munro showed that the survival rate after neo-adjuvant chemotherapy was a mere 3.7%, as opposed to 12.1% for concurrent chemotherapy. Second, the results of 10 randomized comparative trials in the literature were reviewed. The radiation doses were 40-70 Gy. BLM, MTX, 5-FU, and MMC were administered in 7 trials, and 2 drugs, 5-FU and CDDP, and 5-FU and MMC, were combined in 3 trials. A statistically significant improvement in long-term outcome was only found in one study. In 7 studies it was reported that improvement of results is prospective, but further examination is necessary. Augmentation of the acute radiation effects by concurrent chemotherapy has been reported in many studies. A more adequate randomized comparative study should be carried out based on these findings.

  18. Quadrantectomy and adjuvant radiotherapy for breast cancer

    The conservative treatment of early breast cancer always requires irradiation of residual mammary tissue. The preliminary results obtained in 45 early breast cancer patients, who received quadrantectomy plus axillary dissection, followed by radiation of residual breast are reported. Radiation was performed by the two opposed field technique. In some cases the residual breast tissue was compressed using a special accessory provided with the Theratron 780. In addition to the tumor dose of 50 GY, 10 GY boots was added to the surgical scar using 7 MeV electrons. The 6 patients with positive axillary nodes received 6 courses of adjuvant chemotherapy (CMF) after radiotherapy. All patients are currently alive and free of disease. The 64% (29 patients) were followed up for at least 5 years, and 36% (16 patients) for at least 3 years. Only 2 cases of local recurrence were encountered (4,4%). The esthetic result was satisfactory in all cases. No side effects due to treatment were noted

    Ampullary cancer is an uncommon tumor and tends to have a better prognosis than pancreatic cancer. However, one half of patients will die from recurrent disease suggesting the need for effective adjuvant therapy. Currently, there is lack of randomized trials to guide the use of adjuvant therapy in ampullary cancer.

  5. High-risk bladder cancer: improving outcomes with perioperative chemotherapy

    Daniel Y.C. Heng

    2011-12-01

    Full Text Available Despite treatment with radical cystectomy and pelvic lymph node dissection, muscle invasive bladder cancer has a relapse rate of 50%. Patients can develop regionally advanced or metastatic disease that ultimately leads to death. The addition of neoadjuvant or adjuvant chemotherapy to reduce the risk of relapse and death has been extensively studied over the past two decades. Two contemporary trials coupled with a recent meta-analysis evaluating neoadjuvant chemotherapy demonstrated a modest but real improvement in overall survival. This has made neoadjuvant chemotherapy a standard of care. Clinical trials evaluating adjuvant chemotherapy in patients with high-risk disease have been plagued with statistical flaws and have, therefore, been unable to define the survival impact of this approach. It is hoped that ongoing adjuvant trials that are powered to detect small but meaningful clinical differences will clarify the benefit of chemotherapy after cystectomy. Since there are theoretical advantages and disadvantages to each of these approaches, both are widely used in North America. The evidence behind each approach and potential future developments in this field will be described.

    Full Text Available Background . Complementary and alternative medicine (CAM practices for cancer have become popular among oncology patients. An increasing interest in alternative medicine can be explained by the inefficiency of conventional treatment, dissatisfaction with treating patients like objects, and the will to use all available treatment methods. Objectives . The authors assessed how often patients use CAM methods, and which of them are most popular. Material and methods . The study was conducted in Military Hospital no. 109 and the Independent Public Clinical Hospital no. 1 in Szczecin among 100 chemotherapy patients. This survey-based study was performed using an original questionnaire. Results. Most respondents (68% did not use alternative methods to fight the disease. The most popular treatment methods were: herbal medicine (50%, alternative medicine preparations (38% and diet (25%, and the least common: hypnosis (3% and aromatherapy (3%. Analyzed sociodemographic factors had no effects on a choice of a CAM method. Patients obtained information about CAM methods mainly from the Internet (40%, medical staff (37% and literature (31%. Conclusions . 1. Using CAM by patients receiving chemotherapy for neoplasms is quite a common phenomenon. 2. CAM were more often chosen by women. Neither the duration of the disease nor sociodemographic data had effects on making the decision to use CAM methods. 3. The most popular CAM were: herbal medicine, alternative medicine preparations, and diet. 4. Cancer patients should receive special support from nurses and doctors as well as other members of the therapeutic team. Oncology patients should never be left on their own so that they were forced to seek help and support in therapies unconfirmed by scientific investigation.

  8. Is S-1 a Potential Game Changer in Adjuvant Therapy of Pancreatic Cancer?

    Chakra P Chaulagain

    2013-07-01

    Full Text Available There remains a lack of consensus on the optimal adjuvant therapy for pancreatic cancer. In general, chemoradiation is favored in the United States and gemcitabine based chemotherapy is favored in Europe. Both of these approaches have been shown by large prospective, randomized trials to improve disease free survivals and in some studies overall survival. We present the summary of three abstracts from the 2013 American Society of Clinical Oncology (ASCO Annual Meeting and discuss their potential impact on our clinical practice. Adjuvant oral chemotherapy with S-1 (Fukutomi et al., Abstract#4008 has now emerged as a promising alternative to the traditional gold standard of intravenous gemcitabine in a relatively large randomized phase III clinical trial. Another study by Yoshitomi et al. (Abstract #4056 examined the value of adjuvant chemotherapy with S-1 alone versus combination of S-1 and gemcitabine versus gemcitabine alone in a three arm phase II clinical trial (CAP-002 Study. In terms of biomarkers in pancreatic cancer, Neoptolemos et al. presented the impact of hENT1 tumor levels on the outcome of the patients with pancreatic cancer (Abstract #4006 who had received adjuvant chemotherapy with either 5-flurouracil or gemcitabine in the ESPAC trial.

    AIM: To analyze the outcome of patients who received concurrent capecitabine (Xeloda) and radiation (XRT) compared to the established concurrent 5-fluorouracil (5-FU) with radiation (5FU-RT) and fluoropyrimidine-based chemotherapy alone as adjuvant treatment in gastric cancers.

  10. Adjuvant treatment and outcomes of stage III endometrial carcinoma

    Surgery with staging using FIGO (1988) classification is accepted management for stage III endometrial carcinoma. The delivery of adjuvant therapy is controversial and tends to be individualised. Retrospective review of stage III endometrial carcinoma patients who underwent radical surgery at the Royal Adelaide and Queen Elizabeth Hospitals from 1984 to 2003 was carried out. Medical records were reviewed for details of patient characteristics, surgery, histopathology, adjuvant therapy and recurrence/survival. Sixty-six patients with a median age of 69 (37-97), had a median follow-up of 26 months (1-188 ). For all stage III patients, the actuarial 5-year disease-free and overall survivals were 50 and 43% respectively. Thirty-five patients received pelvic +/- paraaortic radiotherapy, 5 whole abdominal radiotherapy, 14 vaginal brachytherapy boost, 10 chemotherapy and 13 adjuvant hormones. Forty-six percent of patients recurred in a median time of 13 months (0-95). For these patients, the sites of first recurrence were pelvis in 27%, pelvis and abdomen in 23%, abdomen alone in 13%, distant alone in 27%, distant and abdominal in 7% and all three sites in 3%. On univariate analysis disease-free survival was impacted by; age, grade, parametrial involvement, number of extrauterine sites, lymphovascular invasion, adjuvant radiotherapy to the pelvis alone and postoperative macroscopic residual disease. Lymphovascular invasion, post-operative residual disease and adjuvant pelvic radiotherapy remained significant on multivariate analysis. These outcomes for stage III endometrial carcinoma are comparable to the current literature. Ongoing research is required to establish the most appropriate adjuvant therapy in these high risk patients

  11. Adjuvant chemo-radiation for gastric adenocarcinoma: an institutional experience

    Studies have shown that surgery alone is less than satisfactory in the management of early gastric cancer, with cure rates approaching 40%. The role of adjuvant therapy was indefinite until three large, randomized controlled trials showed the survival benefit of adjuvant therapy over surgery alone. Chemoradiation therapy has been criticized for its high toxicity. 24 patients diagnosed between September 2001 and July 2007 were treated with adjuvant chemoradiation. 18 patients had the classical MacDonald regimen of 4500 cGy of XRT and chemotherapy with 5-fluorouracil (5FU) and leucovorin, while chemotherapy consisted of 5FU/Cisplatin for 6 patients. This series consisted of non-metastatic patients, 17 females and 7 males with a median age of 62.5 years. 23 patients (96%) had a performance status of 0 or 1. The full course of radiation therapy (4500 cGy) was completed by 22 patients (91.7%). Only 7 patients (36.8%) completed the total planned courses of chemotherapy. 2 local relapses (10%), 2 regional relapses (10%) and 2 distant relapses (10%) were recorded. Time to progression has not been reached. 9 patients (37.5%) died during follow-up with a median overall survival of 75 months. Patients lost a mean of 4 Kgs during radiation therapy. We recorded 6 episodes of febrile neutropenia and the most frequent toxicity was gastro-intestinal in 17 patients (70.8%) with 9 (36%) patients suffering grade 3 or 4 toxicity and 5 patients (20%) suffering from grade 3 or 4 neutropenia. 4 (17%) patients required total parenteral nutrition for a mean duration of 20 days. 4 patients suffered septic shock (17%) and 1 patient developed a deep venous thrombosis and a pulmonary embolus. Adjuvant chemo-radiation for gastric cancer is a standard at our institution and has resulted in few relapses and an interesting median survival. Toxicity rates were serious and this remains a harsh regimen with only 36.8% of patients completing the full planned courses of chemotherapy. This is due to

  13. Adjuvant therapies for colorectal cancer

    2007-01-01

    The management of colon and rectal cancer has changed dramatically over the last 25 years. The use of adjuvant therapies has become standard practice in locally advanced (stage Ⅲ and selected stage Ⅱ) colorectal cancer. Improved surgical techniques, chemotherapeutics and radiotherapy are resulting in higher cure rates and the development of agents targeting proliferative and angiogenic pathways offer further promise. Here we explore risk factors for local and distant recurrence after resection of colon and rectal cancer, and the role of adjuvant treatments. Discussion will focus on the evidence base for adjuvant therapies utilised in colorectal cancer, and the treatment of sub-groups such as the elderly and stage Ⅱ disease. The role of adjuvant radiotherapy in rectal cancer in reduction of recurrence will be explored and the role and optimal methods for surveillance post-curative resection with or without adjuvant therapy will also be addressed.

  14. Promoter methylation and large intragenic rearrangements of DPYD are not implicated in severe toxicity to 5-fluorouracil-based chemotherapy in gastrointestinal cancer patients

    Severe toxicity to 5-fluorouracil (5-FU) based chemotherapy in gastrointestinal cancer has been associated with constitutional genetic alterations of the dihydropyrimidine dehydrogenase gene (DPYD). In this study, we evaluated DPYD promoter methylation through quantitative methylation-specific PCR and screened DPYD for large intragenic rearrangements in peripheral blood from 45 patients with gastrointestinal cancers who developed severe 5-FU toxicity. DPYD promoter methylation was also assessed in tumor tissue from 29 patients Two cases with the IVS14+1G > A exon 14 skipping mutation (c.1905+1G > A), and one case carrying the 1845 G > T missense mutation (c.1845G > T) in the DPYD gene were identified. However, DPYD promoter methylation and large DPYD intragenic rearrangements were absent in all cases analyzed. Our results indicate that DPYD promoter methylation and large intragenic rearrangements do not contribute significantly to the development of 5-FU severe toxicity in gastrointestinal cancer patients, supporting the need for additional studies on the mechanisms underlying genetic susceptibility to severe 5-FU toxicity

    2016-06-01

    The optimal delay in the start of chemotherapy following rectal cancer surgery has not yet been identified. However, postponed adjuvant therapy has been proven to be connected with a significant survival detriment. We aimed to investigate whether the time to initiation of adjuvant treatment can be influenced by the application of minimally invasive surgery rather than traditional open surgery. By comprehensively evaluating the available inherent literature, several factors appear to be associated with delayed postoperative chemotherapy. Some of them are strictly related to surgical short-term outcomes. Laparoscopy results in shortened length of hospital stay, reduced surgical morbidity and lower rate of wound infection compared to conventional surgery. Probably due to such advantages, the application of minimally-invasive surgery to treat rectal malignancies seems to impact favorably the possibility to start adjuvant chemotherapy within an adequate timeframe following surgical resection, with potential improvement in patient survival.

    INTRODUCTION: The traditional first-line treatment for patients with advanced ovarian cancer with primary debulking surgery (PDS) and adjuvant chemotherapy is controversial as some authors report a potential benefit from the alternative treatment with neoadjuvant chemotherapy (NACT) and interval...... debulking surgery. The aim of this study was to investigate the use of NACT in Denmark in regard to increased use and regional differences. MATERIAL AND METHODS: Stage IIIC and IV ovarian cancer patients treated in the five Danish tertiary referral centres in the 2005-2010-period were included. The study...... is based on validated data from The Danish Gynaecological Cancer Database. RESULTS: Of the 1,367 eligible patients 1,069 were treated with PDS and 298 with NACT. In 2005-2007, 11% of patients were treated with NACT. In 2008-2010, this percentage had risen to 30% (p

    Pancreatic cancer ranks tenth in terms of newly diagnosed cases, but just 10%-15% of these patients can undergo resection. Survival after curative surgery is dismal, as recurrences occur either locally or in the liver. Adjuvant treatment with either chemotherapy or chemoradiation (with or without maintenance chemotherapy) has been employed, to improve the poor prognosis. Justification for the use of chemoradiation, with follow on chemotherapy, is based on the results of an underpowered 1987 GITSG study, which closed prematurely and compared intervention to observation. There has been no survival advantage demonstrated in the one randomized controlled trial that examined chemoradiation compared to chemotherapy. There is a clear cut survival advantage however with chemotherapy compared to observation, based on the results from two large randomized controlled trials, and supported by an individual patient data meta-analysis. The standard of care for adjuvant therapy based on level Ⅰ evidence (from the ESPAC-1 trial) is post operative chemotherapy using 5-Fluorouracil with folinic acid providing a best estimate of 29% five years survival.

  19. Innate immunity and adjuvants.

    Akira, Shizuo

    2011-10-12

    Innate immunity was for a long time considered to be non-specific because the major function of this system is to digest pathogens and present antigens to the cells involved in acquired immunity. However, recent studies have shown that innate immunity is not non-specific, but is instead sufficiently specific to discriminate self from pathogens through evolutionarily conserved receptors, designated Toll-like receptors (TLRs). Indeed, innate immunity has a crucial role in early host defence against invading pathogens. Furthermore, TLRs were found to act as adjuvant receptors that create a bridge between innate and adaptive immunity, and to have important roles in the induction of adaptive immunity. This paradigm shift is now changing our thinking on the pathogenesis and treatment of infectious, immune and allergic diseases, as well as cancers. Besides TLRs, recent findings have revealed the presence of a cytosolic detector system for invading pathogens. I will review the mechanisms of pathogen recognition by TLRs and cytoplasmic receptors, and then discuss the roles of these receptors in the development of adaptive immunity in response to viral infection.

    Full Text Available Background Postmastectomy adjuvant therapy is used to prevent locoregional recurrenceand improve overall breast cancer specific survival rates. However, it can adversely affectthe cosmetic results of reconstruction. Therefore, the authors examined flap stability andpatients’ satisfaction with immediate breast reconstruction after adjuvant therapy.Methods We retrospectively reviewed the medical records of 204 patients from January2006 to November 2011. For complication rates, the authors categorized the patients whounderwent the immediate breast reconstruction into 4 groups: adjuvant chemotherapyand radiotherapy group, adjuvant chemotherapy only group, adjuvant radiotherapy onlygroup, and the group that did not undergo adjuvant therapy. For comparison of patients’satisfaction, the study was performed with an additional 16 patients who had undergonedelayed breast reconstruction.Results Regarding complication rates, the group that had undergone adjuvant therapyshowed no significant difference compared to the group that did not undergo adjuvanttherapy. In evaluating the patients’ satisfaction, there was no significant difference.Conclusions Even after adjuvant therapy, immediate breast reconstruction showed goodresults with respect to flap stability and patients’ satisfaction.

  4. Systemic chemotherapy for metastatic breast cancer

    Yannan Zhao; Biyun Wang

    2015-01-01

    Breast cancer is the leading cause of cancer among women worldwide and the most common cancer in China. Many factors influence the treatment strategy for metastatic breast cancer (MBC). Chemotherapy should be administered to patients with hormone receptor-negative tumors, symptomatic visceral metastasis, and a short disease-free interval. Sequential single-agent chemotherapy has similar efficacy as combination agents in terms of overall survival and quality of life. Anthracyclines are the cornerstone of first-line treatment for MBC, and taxanes represent the second treatment option after resistance. When progression or intolerable toxicity occurs after optimal treatment, the alternative treatments include capecitabine, vinorel-bine, and gemcitabine. Ixabepilone and eribulin are relatively new effective single agents. A combination of cytotoxic agents for patients with rapid clinical progression can further improve the overall response rate and time to progression compared to single-agent treatment. For patients with MBC who were pretreated with anthracyclines in the neoadjuvant/adjuvant setting, a taxane-containing regimen such as docetaxel plus capecitabine or gemcitabine plus paclitaxel should be administered. Platinum-based therapies such as cisplatin or carboplatin have a role in the treatment of triple-negative breast cancer. Meanwhile, the efficacy of the addition of targeted drugs such as iniparib, bevacizumab, and cetuximab to chemotherapy remains unproven. Maintenance chemotherapy is routinely recommended in clinical practice at present. Patients who were previously treated with paclitaxel and gemcitabine have better progression-free and overall survival with maintenance chemotherapy according to a Korean phase Ⅲ clinical trial. Sequential maintenance treatment with capecitabine monotherapy after capecitabine-based combination chemotherapy (X-based X) appears favorable based on a series of domestic studies.

    Full Text Available Objective. This study was undertaken to determine the average relative dose intensity (RDI of chemotherapy administered to patients in a community-based outpatient cancer center. Methods. A retrospective review of medical records in an outpatient cancer center was conducted for patients initiating systemic chemotherapy in 2007 for a diagnosis of lymphoma, breast, lung, ovary, or colon cancer. Eighty-four records meeting the inclusion criteria were reviewed for demographic information, primary tumor type, chemotherapy regimen, staging at diagnosis, presence of disease progression, and mortality status. Regimen data included: chemotherapeutic agents used, dosages administered, dates of administration, treatment intent (adjuvant vs. metastatic, and granulocyte colony-stimulating factor (G-CSF usage per cycle. Mean summary statistics were calculated and average RDI was analyzed. Results. The overall RDI at our institution was 83% (n=65. The RDI for those receiving adjuvant chemotherapy was 85% (n=51, whereas for those receiving chemotherapy for metastatic disease the RDI was 76% (n=14. Fifty-four percent (n=35 of the regimens met or exceeded the recommended minimum goal RDI of > 85%. Conclusions. Overall the average RDI at our institution was 83%, slightly below the goal of ≥ 85%. Patients with potentially curable malignancies receiving adjuvant chemotherapy reached the threshold RDI; however, areas for quality improvement exist at our institution.

  9. A Review and Prospect on Herbicide Adjuvants

    2005-01-01

    The history, present status and future prospects of adjuvants application in herbicides were briefly reviewed. Adjuvants can be separated into two groups, activator adjuvants and utility adjuvants. The former directly enhances the efficacy of a herbicide through increasement of herbicide absorption, spreading, cuticular penetration, rainfastness and retention enhancement, and photodegradation of the herbicide can also be decreased. And the latter is utilized for improving application characteristics, behaviors and physical properties of herbicides and reducing or minimizing unwanted side effects on application.

  10. Carcinoma of the male breast: A review of adjuvant therapy

    The purpose of the present paper was to evaluate the characteristics and outcomes of male breast cancer patients seen for adjuvant therapy at a single institution. A retrospective review of computerized records in the Departments of Medical and Radiation Oncology at the Royal Prince Alfred Hospital (RPAH) was undertaken. Between 1983 and 1996, 24 men were referred for treatment of breast cancer. Of these, 19 had localized breast cancer, four had metastatic disease and one had ductal carcinoma in situ (DCIS). The median age was 57.5 years (range: 26-78) and median follow-up was 6.2 years (range: 0.6-36). Pathological staging was performed. Survival was assessed using actuarial life table analysis. All patients underwent surgery. Eleven patients received radiotherapy. The median dose and dose per fraction were 50 Gy and 2 Gy, respectively. Adjuvant systemic therapy was delivered to 10 patients, of whom nine were node-positive. Four patients received chemotherapy alone, three patients received chemotherapy and tamoxifen, and three patients received tamoxifen only. Seven patients relapsed (one local, five distant, one both). Of the two patients with local relapses, one had received radiotherapy. Of the distant failures, four of six patients had no systemic therapy. There were only two node-positive patients who were not given systemic treatment and both relapsed. Median survival in all patients with invasive cancer was 7.5 years, and in those with localized disease it was 7.6 years. The median survival of node-positive patients was 3.8 years. In node-negative patients the median survival had not been reached at a median follow-up of 6.2 years. Systemic therapy was found to be beneficial in patients with node-positive disease. Chemotherapy was administered more frequently than hormonal therapy. The median survivals were consistent with those reported in other series. Copyright (1999) Blackwell Science Pty Ltd

  11. Preliminary Experience with Locoregional Intraarterial Chemotherapy of Uterine Cervical or Endometrial Cancer Using the Peripheral Implantable Port System (PIPSTM): A Feasibility Study

    The purpose of this study was to assess the suitability of a percutaneously implantable catheter port system (PIPS)for repeated intraarterial locoregional chemotherapy (ILC) for cervical and endometrial carcinoma. In 30 patients with advanced, recurrent, or high-risk cervical (n 23) or endometrial(n = 7) carcinoma, PIPS for ILC was implanted via a femoral access, the catheter localized in the infrarenal abdominal aorta. Chemotherapy was performed adjuvantly after surgery(n = 14) or neo-adjuvantly to enable surgery, or for palliation (n = 16). Port implantation, catheter placement, and repeated port puncture was uneventful in all patients.Complications included catheter dislocation (n = 1),catheter thrombosis (n = 2), subcutaneous infection(n = 1), port-bed skin atrophy (n = 1),requiring port explantation in 3 patients. At 2 years follow-up,complete remission was observed in 7/14 patients with adjuvant chemotherapy, partial remission in 3/14. Successful down-staging could be achieved in 4/8 patients with neo-adjuvant chemotherapy. The PIPS is suitable for repeated ILC which may be a valuable method for pre- and post-surgical therapy of advanced or high-risk cervical and endometrial cancer, for adjuvant chemotherapy as well as neo-adjuvantly for down-staging, or for palliation

    2013-01-01

    There remains a lack of consensus on the optimal adjuvant therapy for pancreatic cancer. In general, chemoradiation is favored in the United States and gemcitabine based chemotherapy is favored in Europe. Both of these approaches have been shown by large prospective, randomized trials to improve disease free survivals and in some studies overall survival. We present the summary of three abstracts from the 2013 American Society of Clinical Oncology (ASCO) Annual Meeting and discuss their poten...

    Purpose: To evaluate the tolerability and toxicity of administering vaginal brachytherapy (VB) concurrently during chemotherapy compared with the sequential approach for patients with endometrial cancer. Methods and Materials: A retrospective analysis of 372 surgically staged patients with endometrial cancer American Joint Committee on Cancer 2009 stages I to IV treated with adjuvant postoperative radiation therapy (RT) at our institution from 2001 to 2012 was conducted. All patients received VB + external beam RT (EBRT) + 6 cycles of adjuvant carboplatin- and paclitaxel-based chemotherapy. The VB mean dose was 15.08 Gy (range, 15-20 Gy), with 3 to 4 weekly applications, and the EBRT mean dose was 45 Gy delivered with 3-dimensional or intensity modulated RT techniques. Hematologic, gastrointestinal (GI), and genitourinary (GU) toxicities were assessed by Common Toxicity Criteria (CTC) and compared between sequential and concurrent chemotherapy and VB schedules. Results: Among patients who received RT and adjuvant chemotherapy, 180 of 372 patients (48%) received RT sandwiched between cycles 3 and 4 of chemotherapy. A separate group of 192 patients (52%) were treated with VB during the first 3 cycles of chemotherapy, with a weekly application on nonchemotherapy days, and received the EBRT portion in a sandwiched fashion. Patients treated with VB during chemotherapy had a decreased overall treatment time by 4 weeks (P<.001; 95% confidence interval: 3.99-4.02) and sustained no difference in CTC-graded acute hematologic, GI, or GU toxicities in comparison with the patients treated with VB and chemotherapy in a sequential manner (P>.05). CTC grade 3 or 4 hematologic, GI, and GU toxicities were zero. Conclusions: VB during chemotherapy is well tolerated, decreases overall treatment time, and does not render more toxicity than the sequential regimen.

    2015-01-01

    Epidermal growth factor receptor-tyrosine-kinase inhibitors (EGFR-TKIs) brought a significant revolution in the treatment of non-small-cell lung cancer (NSCLC). In a short period of time, EGFR-TKIs became the standard of treatment for mutation-positive, advanced stage non-squamous NSCLC. In recent years, second- and third-generation EGFR-TKIs are emerging, further widening the clinical use. However, the question of EGFR-TKIs efficiency in the treatment of early stage NSCLC still remains open. Early clinical trials failed to approve the use of EGFR-TKIs in adjuvant setting. The majority of these early trials were performed in unselected NSCLC populations and without standardized biomarker identification. One should certainly not rely solely on these results and dismiss the use of EGFR-TKIs as adjuvant therapy. Many important questions are still unanswered. Most important issues such as stage heterogeneity (IA–IIIA), timing (after or concomitantly with chemotherapy), and type of administration (monotherapy or combination) need to be answered in near future. Adjuvant TKIs in the treatment of lung cancer might offer significant number of advancements. Having in mind the significant duration of response observed in advance disease setting, there could be place for prolongation of response in adjuvant setting potentially, leading to improvement in survival. TKIs could offer less-toxic adjuvant treatment with better efficiency than chemotherapy. However, there is a chronic lack of randomized controlled trials in this field, leading to inability to draw any scientifically sound conclusion with regard to the adjuvant treatment. For now, the use of EGFR-TKIs outside clinical trial setting is not recommended. The purpose of this review is to evaluate current and available data. PMID:26508876

  18. Chemotherapy in Prostate Cancer.

    Hurwitz, Michael

    2015-10-01

    For approximately a decade, chemotherapy has been shown to prolong life in patients with metastatic castration-resistant prostate cancer (mCRPC). Since that time, however, only two agents have proven to prolong life (docetaxel and cabazitaxel). However, in the last year, the addition of chemotherapy to primary hormonal therapy became a standard of care for high-volume castration-sensitive metastatic disease. Here I will review current prostate cancer chemotherapies, mechanisms of resistance to those therapies, and ongoing clinical studies of chemotherapy combinations and novel chemotherapeutics.

  19. Improving vaccine delivery using novel adjuvant systems.

    Pichichero, Michael E

    2008-01-01

    Adjuvants have been common additions to vaccines to help facilitate vaccine delivery. With advancements in vaccine technology, several adjuvants which activate immune specific responses have emerged. Available data show these adjuvants elicit important immune responses in both healthy and immunocompromised populations, as well as the elderly. Guidelines for the use and licensure of vaccine adjuvants remain under discussion. However, there is a greater understanding of the innate and adaptive immune response, and the realization of the need for immune specific adjuvants appears to be growing. This is a focused review of four adjuvants currently in clinical trial development: ASO4, ASO2A, CPG 7907, and GM-CSF. The vaccines including these adjuvants are highly relevant today, and are expected to reduce the disease burden of cervical cancer, hepatitis B and malaria. PMID:18398303

  20. Postoperative radio-chemotherapy in locally advanced gastric cancer

    Background: Overall 5 years survival for surgically excised gastric cancer is 30%. Adjuvant treatment may improve the surgical results. Aim: To assess treatment results and toxicity in patients with surgically excised gastric cancer, treated with adjuvant radiotherapy and concomitant continuous 5-Fluorouracil (5-FU). Material and Methods: Forty one patients aged 32 to 73 years (29 males) with stage II-IVA gastric cancer, subjected to a total or subtotal gastrectomy and D2 nodal dissection between 1997 to 2006, were studied. They received adjuvant radiotherapy to the gastric bed and draining lymphatic nodes in a total dose of 50.4 Gy in 28 fractions and chemotherapy with continuous infusion 5-FU, 200 mg/m2/day. Results were compared to historical controls matched according to demographic parameters and tumor characteristics. Results: Eighteen patients were in stage II, 10 in stage IIIA, nine in stage IIIB and four in stage IVA. Twelve patients had an N0 nodal status, 15 were N1, nine were N2 and five were N3. After a mean follow up of 32 months, 26 patients (63%) were alive. Five year overall survival was 49.6% for surgery plus radiochemotherapy compared to 30.7% for the historical group subjected only to surgery (p =0.002). Radiotherapy was associated with grade 1-2 toxicity and treatment was completed without interruptions in all patients. Chemotherapy was delayed temporarily in 3 patients. Conclusions: Adjuvant radio-chemotherapy improved overall survival in gastric cancer, compared to historical controls subjected only to surgical treatment

  1. Borderline ovarian tumors: the issues of chemotherapy and prognosis

    I. Yu. Davydova

    2015-01-01

    Full Text Available The paper discusses the results of studies conducted in international clinics and the authors’ data on approaches to treating borderline ovarian tumors. It analyzes and comparatively assesses groups of patients who have received chemotherapy and those who have not. The authors mainly state the view that chemotherapy for borderline ovarian tumors affects their prognosis in no way, but makes it even worse in a number of investigations. They also give the data of their observations, which show that attitudes towards chemotherapy for borderline ovarian tumors change in different decades. If in the 1980s chemotherapy was a mandatory treatment stage, it is nowadays prescribed only in exceptional cases in the author’s clinic. Different predictors, such as microinvasion, the micropapillary pattern of borderline tumors, invasive implants, their impact on the probability of recurrences and survival are being investigated. Whether chemotherapy against unfavorable factors, such as invasive implants, may be used is considered. There is evidence that conservative and ultraconservative surgeries for borderline ovarian tumors may be performed. Ultraconservative operations that can spare ovarian tissue as much as possible demonstrate the best pregnancy and labor outcomes as compared with conservative surgical approaches. Thus, this paper considers whether it is expedient to use chemotherapy in patients with borderline ovarian tumors. It also discusses scientists’ views and the authors’ data on neoadjuvant and adjuvant treatments, predictors in borderline ovarian tumors, and survival rates in different international clinics.

  4. Chemotherapy-Related Neurotoxicity.

    Taillibert, Sophie; Le Rhun, Emilie; Chamberlain, Marc C

    2016-09-01

    Chemotherapy may have detrimental effects on either the central or peripheral nervous system. Central nervous system neurotoxicity resulting from chemotherapy manifests as a wide range of clinical syndromes including acute, subacute, and chronic encephalopathies, posterior reversible encephalopathy, acute cerebellar dysfunction, chronic cognitive impairment, myelopathy, meningitis, and neurovascular syndromes. These clinical entities vary by causative agent, degree of severity, evolution, and timing of occurrence. In the peripheral nervous system, chemotherapy-induced peripheral neuropathy (CIPN) and myopathy are the two main complications of chemotherapy. CIPN is the most common complication, and the majority manifest as a dose-dependent length-dependent sensory axonopathy. In severe cases of CIPN, the dose of chemotherapy is reduced, the administration delayed, or the treatment discontinued. Few treatments are available for CIPN and based on meta-analysis, duloxetine is the preferred symptomatic treatment. Myopathy due to corticosteroid use is the most frequent cause of muscle disorders in patients with cancer. PMID:27443648

    2011-03-01

    Full Text Available Abstract Background Many adjuvant trials have been undertaken in an attempt to reduce the risk of recurrence among patients who undergo surgical resection for locally advanced renal cancer. However, no clear benefit has been identified to date. This systematic review was conducted to examine the exact role of adjuvant therapy in renal cancer setting. Methods Randomized controlled trials were searched comparing adjuvant therapy (chemotherapy, vaccine, immunotherapy, biochemotherapy versus no active treatment after surgery among renal cell cancer patients. Outcomes were overall survival (OS, disease-free survival (DFS, and severe toxicities. Risk ratios (RR, hazard ratios (HR and 95% confidence intervals were calculated using a fixed-effects meta-analysis. Heterogeneity was measured by I2. Different strategies of adjuvant treatment were evaluated separately. Results Ten studies (2,609 patients were included. Adjuvant therapy provided no benefits in terms of OS (HR 1.07; 95%CI 0.89 to 1.28; P = 0.48 I2 = 0% or DFS (HR 1.03; 95%CI 0.87 to 1.21; P = 0.77 I2 = 15% when compared to no treatment. No subgroup analysis (immunotherapy, vaccines, biochemotherapy and hormone therapy had relevant results. Toxicity evaluation depicted a significantly higher frequency of serious adverse events in the adjuvant group. Conclusions This analysis provided no support for the hypothesis that the agents studied provide any clinical benefit for renal cancer patients although they increase the risk of toxic effects. Randomized trials are underway to test targeted therapies, which might open a new therapeutic frontier. Until these trials yield results, no adjuvant therapy can be recommended for patients who undergo surgical resection for renal cell cancer.

  6. Role of Adjuvant Chemoradiation Therapy in Adenocarcinomas of the Ampulla of Vater

    Purpose: The role of adjuvant chemoradiation therapy (CRT) in the treatment of ampullary cancers remains undefined. We retrospectively compared treatment outcomes in patients treated with pancreaticoduodenectomy alone versus those who received additional adjuvant CRT. Methods and Materials: Between May 1990 and January 2006, 54 of 96 patients with ampullary adenocarcinoma who underwent potentially curative pancreaticoduodenectomy also received adjuvant CRT. The median preoperative radiation dose was 45 Gy (range, 30-50.4 Gy) and median postoperative dose was 50.4 Gy (range, 45-55.8 Gy). Concurrent chemotherapy included primarily 5-fluorouracil (52%) and capecitabine (43%). Median follow-up was 31 months. Univariate and multivariate statistical methodologies were used to determine significant prognostic factors for local control (LC), distant control (DC), and overall survival (OS). Results: Actuarial 5-year LC, DC, and OS were 77%, 69%, and 64%, respectively. On univariate analysis, age, gender, race/ethnicity, tumor grade, use of adjuvant treatment, and sequencing of adjuvant therapy were not significantly associated with LC, DC, or OS. However, on univariate analysis, T3/T4 tumor stage was prognostic for poorer LC and OS (p = 0.02 and p < 0.001, respectively); node-positive disease was prognostic for poorer LC (p = 0.03). On multivariate analysis, T3/T4 tumor stage was independently prognostic for decreased OS (p = 0.002). Among these patients (n = 34), those who received adjuvant CRT had a trend toward improved OS (median, 35.2 vs. 16.5 months; p = 0.06). Conclusions: Ampullary cancers have a distinctly better treatment outcome than pancreatic adenocarcinomas. Higher primary tumor stage (T3/T4), an independent adverse risk factor for poorer treatment outcomes, may warrant the addition of adjuvant CRT to pancreaticoduodenectomy

  8. Arterial, portal, or systemic chemotherapy for patients with hepatic metastasis of colorectal carcinoma.

    Kemeny, N; Fata, F

    1999-01-01

    Hepatic metastases from colorectal carcinoma are common and may be resected for cure. The response of liver metastases to systemic chemotherapy is low. In contrast, hepatic arterial chemotherapy produces higher response rates than systemic chemotherapy, but randomized trials have not definitely proved a survival advantage because they allowed cross over. Most adjuvant portal vein chemotherapy studies have shown a survival advantage over the control group, but it is not clear whether this benefit is from the portal vein therapy or from immediate postoperative chemotherapy, since there is rarely a reduction in liver metastases. We describe the results of systemic, hepatic artery infusion, and portal therapy for patients with liver metastases of colorectal carcinoma. PMID:10436236

  9. The role of neoadjuvant and adjuvant treatment for adenocarcinoma of the upper gastrointestinal tract

    Matuschek C

    2011-06-01

    Full Text Available Abstract Both locally advanced adenocarcinoma of the stomach and gastro-esophageal junction are associated with poor prognosis due to the lack of effective treatment. Recently multimodal treatment consisting of neoadjuvant chemotherapy in combination with radiotherapy is reported to improve survival when compared to surgery alone. Neoadjuvant therapy in these locally advanced tumors allows for early tumor responses and the extent of tumor regression that can be achieved is considered a significant prognostic factor. This, in turn, increases the resectability of these tumors. Also due to the high frequency of lymph node metastasis, patients with locally advanced adenocarcinoma should undergo a D2 lymphadenectomy. Postoperative chemoradiation and perioperative chemotherapy have been studied in gastric adenocarcinomas and showed a survival benefit. However, the surgical techniques used in these trials are no longer considered to be standard by today's surgical practice. In addition, there are no standard recommendations for adjuvant chemotherapy or chemoradiation after R0 resection and adequate lymph node dissection.

    The role of chemotherapy in prostate cancer continues to evolve. In men with symptomatic androgen-independent prostate cancer, significant reduction in pain and analgesic requirements are achievable with mitoxantrone and glucocorticoid combinations compared with glucocorticoids alone. However, survival rates are not improved. Taxane-based combinations with estramustine phosphate or other new agents show promise. Prostate-specific antigen response rates with these combinations appear to be 1.5 to 2 times more frequent than with mitoxantrone-based combinations. Randomized trials of taxane versus mitoxantrone-based therapies are underway. New agents and applications of current agents in adjuvant settings should be explored if survival in men with prostate cancer is to be improved. PMID:12756087

  12. Adjuvant therapy in case of mammary carcinoma (high risk)

    108 patients with high risk stage of a mammary carcinoma (four or more positive axillar lymph nodes) were submitted after surgery to a prospectively randomized study: a postirradiation in three series with additional administration of tamoxifen was opposed to a reduced-dose irradiation and subsequent simultaneous combination of polychemotherapy and irradiation. In patients with an age of less than 50 years, the combination of chemotherapy and radiotherapy caused a significant prolongation of the recurrence-free interval (>57 months versus 12,75 months). The comparison with literature shows that an average interval of 39.1 months without recurrences for the total group of patients treated with combination therapy corresponds to the result of a high-dose adjuvant CMF therapy. With respect to mean life expectancy, there was no significant difference between both groups of randomization. (orig.)

    2012-01-01

    Renal cell carcinoma (RCC) is one of the ten most frequent solid tumors worldwide. Recent innovations in the treatment of metastatic disease have led to new therapeutic approaches being investigated in the adjuvant setting. Observation is the only current standard of care after radical nephrectomy, although there is evidence of efficacy of adjuvant use of vaccine among all the strategies used. This article aims to collect published experiences with systemic adjuvant approaches in RCC and to d...

  15. Adjuvant chemoradiotherapy for adenocarcinoma of the stomach. A new progress?

    Frequency of local and distant failures after gastrectomy has led to extended lymph nodes dissection to obtain a better locoregional control. However, five year survival rates were not significantly different between patients undergoing D2 and D1 lymphadenectomy, and higher morbidity and post operative deaths were reported in large randomized trials (respectively 25% vs 48% and 4 vs 13%). Additionally, several met-analysis failed to demonstrate a significant survival advantage with adjuvant chemotherapy. The results of the first trial demonstrating one advantage to adjuvant post-operative chemoradiotherapy should modify the standard care. Disease free and overall survival after surgery alone and after surgery and concurrent chemoradiotherapy were respectively 31% vs 48% and 41% vs 50%. The inter-group trial demonstrate that better local control improve survival if radiation fields include stamps, tumour bed, proximal nodal chains and nodes corresponding to D2 extended lymph nodes dissection. Treatment was feasible with few severe toxic effects (1%). Of the 281 patients, 17% stopped treatment because toxic effects. Technical modalities of radiotherapy and post-operative nutrition support which are critical points of interest for this treatment, are also discussed. (authors)

  17. Chemotherapy as a component of multimodal therapy for gastric carcinoma

    Yasuhiro Kodera; Michitaka Fujiwara; Masahiko Koike; Akimasa Nakao

    2006-01-01

    Prognosis of locally advanced gastric cancer remains poor, and several multimodality strategies involving surgery, chemotherapy, and radiation have been tested in clinical trials. Phase Ⅲ trial testing the benefit of postoperative adjuvant chemotherapy over treatment with surgery alone have revealed little impact on survival, with the exception of some small trials in Western nations. A large trial from the United States exploring postoperative chemoradiation was the first major success in this category. Results from Japanese trials suggest that moderate chemotherapy with oral fluoropyrimi dines may be effective against less-advanced (T2-stage)cancer, although another confirmative trial is needed to prove this point. Investigators have recently turned to neoadjuvant chemotherapy, and some promising results have been reported from phase Ⅱ trials using active drug combinations. In 2005, a large phase Ⅲ trial testing preand postoperative chemotherapy has proven its survival benefit for resectable gastric cancer. Since the rate of pathologic complete response is considered to affect treatment results of this strategy, neoadjuvant chemoradiation that further increases the incidence of pathologic complete response could be a breakthrough, and phase Ⅲ studies testing this strategy may be warranted in the near future.

    2013-01-01

    There is accumulating clinical evidence that chemotherapeutic agents induce neurological side effects, including memory deficits and mood disorders, in cancer patients who have undergone chemotherapeutic treatments. This review focuses on chemotherapy-induced neurodegeneration and hippocampal dysfunctions and related mechanisms as measured by in vivo and in vitro approaches. These investigations are helpful in determining how best to further explore the causal mechanisms of chemotherapy-induced neurological side effects and in providing direction for the future development of novel optimized chemotherapeutic agents.

  2. Adjuvant radiotherapy following radical hysterectomy for patients with stage IB and IIA cervical cancer

    From 1971 through 1984, 320 women underwent radical hysterectomy as primary therapy of stage IB and IIA cervical cancer. Two hundred forty-eight patients (78%) were treated with surgery alone and 72 patients (22%) received adjuvant postoperative external-beam radiotherapy. Presence of lymph node metastasis, large lesion (greater than 4 cm in diameter), histologic grade, race (noncaucasian), and age (greater than 40 years) were significant poor prognostic factors for the entire group of patients. Patients treated with surgery alone had a better disease-free survival than those who received combination therapy (P less than 0.001). However, patients receiving adjuvant radiation therapy had a higher incidence of lymphatic metastases, tumor involvement of the surgical margin, and large cervical lesions. Adjuvant pelvic radiation therapy did not improve the survival of patients with unilateral nodal metastases or those who had a large cervical lesion with free surgical margins and the absence of nodal involvement. Radiation therapy appears to reduce the incidence of pelvic recurrences. Unfortunately, 84% of patients who developed recurrent tumor after combination therapy had a component of distant failure. The incidence of severe gastrointestinal or genitourinary tract complications was not different in the two treatment groups. However, the incidence of lymphedema was increased in patients who received adjuvant radiation therapy. Although adjuvant radiation therapy appears to be tolerated without a significant increase in serious complications, the extent to which it may improve local control rates and survival in high-risk patients appears to be limited. In view of the high incidence of distant metastases in high-risk patients, consideration should be given to adjuvant systemic chemotherapy in addition to radiation therapy

  4. Adjuvants: Classification, Modus Operandi, and Licensing

    Apostólico, Juliana de Souza

    2016-01-01

    Vaccination is one of the most efficient strategies for the prevention of infectious diseases. Although safer, subunit vaccines are poorly immunogenic and for this reason the use of adjuvants is strongly recommended. Since their discovery in the beginning of the 20th century, adjuvants have been used to improve immune responses that ultimately lead to protection against disease. The choice of the adjuvant is of utmost importance as it can stimulate protective immunity. Their mechanisms of action have now been revealed. Our increasing understanding of the immune system, and of correlates of protection, is helping in the development of new vaccine formulations for global infections. Nevertheless, few adjuvants are licensed for human vaccines and several formulations are now being evaluated in clinical trials. In this review, we briefly describe the most well known adjuvants used in experimental and clinical settings based on their main mechanisms of action and also highlight the requirements for licensing new vaccine formulations.

  5. Concurrent chemoradiotherapy in adjuvant treatment of breast cancer

    The optimal sequencing of chemotherapy and radiotherapy after breast surgery was largely studied but remains controversial. Concurrent chemo-radiotherapy is a valuable method for adjuvant treatment of breast cancer which is under ongoing research program in our hospital. We are evaluating the feasibility of the concomitant use of chemotherapy retrospectively. Two hundred forty four women having breast cancer were investigated in a retrospective study. All patients were either treated by radical surgery or breast conservative surgery. The study compares two adjuvant treatments associating concomitant chemotherapy and radiotherapy. In the first group (group A) the patients were treated by chemotherapy and radiotherapy in concomitant way using anthracycline (n = 110). In the second group (group B) the patients were treated by chemotherapy and radiotherapy in concomitant way using CMF treatment (n = 134). Chemotherapy was administered in six cycles, one each 3 weeks. Radiotherapy delivered a radiation dose of 50 Gy on the whole breast (or on the external wall) and/or on the lymphatic region. The Kaplan-Meier method was used to estimate the rates of disease free survival, loco-regional recurrence-free survival and overall survival. The Pearson Khi2 test was used to analyse the homogeneity between the two groups. The log-rank test was used to evaluate the differences between the two groups A and B. After 76.4 months median follow-up (65.3 months mean follow up), only one patient relapsed to loco-regional breast cancer when the treatment was based on anthracycline. However, 8 patients relapsed to loco-regional breast cancer when the treatment was based on CMF. In the anthracycline group, the disease free survival after 5 years, was 80.4% compared to 76.4% in the CMF group (Log-rank test: p = 0.136). The overall survival after 5 years was 82.5% and 81.1% in the anthracycline and CMF groups respectively (Log-rank test: p = 0.428). The loco-regional free survival at 5 years

  7. Survival Benefit of Adjuvant Radiation Therapy for Gastric Cancer following Gastrectomy and Extended Lymphadenectomy

    R. A. Snyder

    2012-01-01

    Full Text Available Purpose. Although randomized trials suggest a survival benefit of adjuvant chemotherapy and radiation therapy (XRT for gastric adenocarcinoma, its use in patients who undergo an extended lymphadenectomy is less clear. The purpose of this study was to determine if a survival benefit exists in gastric cancer patients who receive adjuvant XRT following resection with extended lymphadenectomy. Methods. The SEER registry was queried for records of patients with resected gastric adenocarcinoma from 1988 to 2007. Multivariable Cox regression models were used to assess independent prognostic factors affecting overall survival (OS and disease-specific survival (DSS. Results. Of 15,060 patients identified, 3,208 (21% received adjuvant XRT. Adjuvant XRT was independently associated with improved OS (HR 0.67, CI 0.64–0.71 and DSS (HR 0.69, CI 0.65–0.73 in stages IB through IV (M0. This OS and DSS benefit persisted regardless of the extent of lymphadenectomy. Furthermore, lymphadenectomy with >25 LN resected was associated with improved OS and DSS compared with 25 LNs results in improved OS and DSS compared with patients who have fewer LNs resected.

  8. Adjuvant whole abdominal radiotherapy in epithelial cancer of the ovary

    Purpose: To reexamine the use of adjuvant radiotherapy in optimally debulked patients. Methods and Materials: Between January 1985 and April 1998, 60 patients were treated with adjuvant whole abdominal radiotherapy (A-WART). The stage distribution was Stage IC in 17 patients, Stage II in 9, and Stage III in 34. The grade distribution was Grade 1 in 9 patients, Grade 2 in 27, and Grade 3 in 24; thus, 60% of the patients had Stage III disease and 40% had Grade 3 tumors. After surgery, no residuum was left in 42 (70%), ≤2 cm in 13 (22%), and >2 cm in 5 (8%) of 60 patients. Of the 60 patients, 19 also received platinum-based chemotherapy; in 12 of the 19, the chemotherapy was before A-WART. Thirty-seven of the patients had undergone previous abdominal procedures and a second-look operation was performed in 25% of them. A-WART consisted of 22 Gy in 22 fractions, at 5 fractions weekly in 90% of the patients. The remaining 10% received 25 Gy in 25 fractions within 5 weeks. The A-WART was delivered using a 4-MV linear accelerator. After abdominal irradiation, a boost to the pelvis was given to reach 45 Gy at 1.8 cGy/fraction, using a 4-15-MV linear accelerator. Results: Treatment was delivered in a median of 50 days (range 48-70). In 12 (20%) of the 60 patients, a transient treatment interruption occurred because of acute toxicity, mainly vomiting and diarrhea. The overall survival rate was 55% at 5 years (median follow-up 96.5 months). Patients with low-histologic grade tumors (Grade 1-2) had a better 5-year survival rate (66%) than those with Grade 3 tumors (35%; p<0.03). A tendency for better survival was found for those with Stage I-II than for those with Stage III (69% vs. 43%). Nonetheless, this difference did not reach statistical significance (p 0.17). For patients receiving chemotherapy, the 5-year survival rate was 51%, not statistically different from the 58% 5-year survival rate observed among those patients without adjuvant chemotherapy (p=0.9).

    2009-01-01

    Full Text Available Although cancer therapies have experienced great success nowadays, yet the associated toxic response and free radicals formation have resulted in significant number of treatment-induced deaths rather than disease-induced fatalities. Complications of chemotherapy have forced physicians to study antioxidant use as adjunctive treatment in cancer. This study aimed to evaluate the antioxidant role of vitamin E and N-acetyl cysteine (NAC in overcoming treatment-induced toxicity in acute lymphoblastic leukaemia (ALL during the intensive period of chemo-/radiotherapy, almost the first two months of treatment. Forty children newly diagnosed with ALL were enrolled in this study. Twenty children (group I have taken vitamin E and NAC supplementations with chemotherapy and the other twenty children (group II have not taken any adjuvant antioxidant therapy. They were evaluated clinically for the occurrence of complications and by the laboratory parameters (blood levels of glutathione peroxidase (Glu.PX antioxidant enzyme, malondialdehyde (MDA, tumor necrosis factor- (TNF-, liver enzymes, and bone marrow picture. Results revealed reduced chemotherapy and radiotherapy toxicity as evidenced by decreasing level of MDA, increasing level of Glu.Px and decreased occurrence of toxic hepatitis, haematological complications, and need for blood and platelet transfusions in group I compared to group II. We can conclude that vitamin E and NAC have been shown to be effective as antioxidant adjuvant therapy in children with ALL to reduce chemo-/radiotherapy-related toxicities during the initial period of treatment.

    Pneumatosis cystoides intestinalis (PCI) is a relatively rare condition characterized by intraluminal gas in the gastrointestinal tract.Several chemotherapeutic agents have been reported to be associated with PCI,although fluorouracil-related PCI is extremely rare.We report a case of a 76-year old man who received adjuvant chemotherapy for rectal cancer with fluorouracil (FU) and leucovorin (LV).After 1 cycle of the treatment,he presented with diarrhea and abdominal pain.Abdominal radiogram revealed the presence of free air under the diaphragm and intramural gas in the intestine.Laparotomy was performed,showing a suspected diagnosis of perforation in the gastrointestinal tract.Intraoperative findings revealed penumatosis of the intestine without evidence of perforation.He was treated supportively and his symptoms improved.In conclusion,we should consider the possibility of PCI occurring in patients with malignancies during chemotherapy treatment.

  12. Combination Chemotherapy for Influenza

    Robert G. Webster

    2010-07-01

    Full Text Available The emergence of pandemic H1N1 influenza viruses in April 2009 and the continuous evolution of highly pathogenic H5N1 influenza viruses underscore the urgency of novel approaches to chemotherapy for human influenza infection. Anti-influenza drugs are currently limited to the neuraminidase inhibitors (oseltamivir and zanamivir and to M2 ion channel blockers (amantadine and rimantadine, although resistance to the latter class develops rapidly. Potential targets for the development of new anti-influenza agents include the viral polymerase (and endonuclease, the hemagglutinin, and the non-structural protein NS1. The limitations of monotherapy and the emergence of drug-resistant variants make combination chemotherapy the logical therapeutic option. Here we review the experimental data on combination chemotherapy with currently available agents and the development of new agents and therapy targets.

  13. Review of Adjuvant Radiochemotherapy for Resected Pancreatic Cancer and Results From Mayo Clinic for the 5th JUCTS Symposium

    Purpose: To present an overview of Phase III trials in adjuvant therapy for pancreatic cancer and review outcomes at the Mayo Clinic after adjuvant radiochemotherapy (RT/CT) for resected pancreatic cancer. Methods and Materials: A literature review and a retrospective review of 472 patients who underwent an R0 resection for T1-3N0-1M0 invasive carcinoma of the pancreas from 1975 to 2005 at the Mayo Clinic, Rochester, MN. Patients with metastatic or unresectable disease at the time of surgery, positive surgical margins, or indolent tumors and those treated with intraoperative radiotherapy were excluded from the analysis. Median radiotherapy dose was 50.4Gy in 28 fractions, with 98% of patients receiving concurrent 5-fluorouracil- based chemotherapy. Results: Median follow-up was 2.7 years. Median overall survival (OS) was 1.8 years. Median OS after adjuvant RT/CT was 2.1 vs. 1.6 years for surgery alone (p = 0.001). The 2-y OS was 50% vs. 39%, and 5-y was 28% vs. 17% for patients receiving RT/CT vs. surgery alone. Univariate and multivariate analysis revealed that adverse prognostic factors were positive lymph nodes (risk ratio [RR] 1.3, p < 0.001) and high histologic grade (RR 1.2, p < 0.001). T3 tumor status was found significant on univariate analysis only (RR 1.1, p = 0.07). Conclusions: Results from recent clinical trials support the use of adjuvant chemotherapy in resected pancreatic cancer. The role of radiochemotherapy in adjuvant treatment of pancreatic cancer remains a topic of debate. Results from the Mayo Clinic suggest improved outcomes after the administration of adjuvant radiochemotherapy after a complete resection of invasive pancreatic malignancies.

  14. Uncaria tomentosa for Reducing Side Effects Caused by Chemotherapy in CRC Patients: Clinical Trial

    2012-01-01

    Full Text Available To evaluate the effectiveness of Uncaria tomentosa in minimizing the side effects of chemotherapy and improving the antioxidant status of colorectal cancer (CRC patients, a randomized clinical trial was conducted. Patients (43 undergoing adjuvant/palliative chemotherapy with 5-Fluorouracil/leucovorin + oxaliplatin (FOLFOX4 were split into two groups: the UT group received chemotherapy plus 300 mg of Uncaria tomentosa daily and the C group received only FOLFOX4 and served as a control. Blood samples were collected before each of the 6 cycles of chemotherapy, and hemograms, oxidative stress, enzymes antioxidants, immunologic parameters, and adverse events were analyzed. The use of 300 mg of Uncaria tomentosa daily during 6 cycles of FOLFOX4 did not change the analyzed parameters, and no toxic effects were observed.

    Zedan, Ahmed; Vilholm, Ole Jakob

    2014-01-01

    Chemotherapy-induced polyneuropathy (CIPN) is a common, but underestimated, clinical challenge. Incidence varies depending on many factors that are equally as important as the type of chemotherapeutic agent itself. Moreover, the assessment of CIPN is still uncertain, as several of the most...... frequently used scales do not rely on a formal neurological evaluation and depend on patients' reports and examiners' interpretations. Therefore, the aim of this MiniReview was to introduce the most common chemotherapies that cause neuropathy, and in addition to this, highlight the most significant...

  16. Integrating Chemotherapy in the Management of Cervical Cancer: A Critical Appraisal.

    Kumar, Lalit; Gupta, Sudeep

    2016-01-01

    The management of locally advanced cervix cancer has undergone a paradigm shift during the last decade. Concurrent chemoradiation (CCRT) (with cisplatin alone or in combination) is currently the standard treatment approach. CCRT results in a 5-year overall survival rate of 66% and a disease-free survival of 58%. About 30-40% of patients with locally advanced cervical cancer fail to achieve complete response to CCRT; alternative approaches are needed to improve the outcome for such patients. Weekly paclitaxel and carboplatin for 4-6 weeks as dose-dense chemotherapy prior to CCRT could be one such potential approach. The role of adjuvant chemotherapy after CCRT in patients with positive lymph nodes, larger tumor volume and stage III-IVA disease needs further exploration. Adjuvant chemotherapy is also being investigated for early-stage (stages IA2, IB1 or IIA) cervical cancer with presence of risk factors such as lymph node metastasis, lymphovascular space invasion and invasion depth of more than 10 mm, microscopic parametrial invasion, non-squamous histology and positive surgical margins. For patients with early-stage disease (IA2-IIA), short-course chemotherapy prior to surgery is associated with an improved outcome in many studies. Neo-adjuvant chemotherapy followed by fertility preservation surgery is feasible in carefully selected young patients with bulky stage IB1 disease. Recently, a number of molecular pathways have been identified as potential therapeutic targets. Bevacizumab - an inhibitor of vascular endothelial growth factor - is associated with improved survival in patients with recurrent/metastatic cervical cancer. Whether bevacizumab and other similar novel agents targeting molecular pathways could be used in front-line treatment along with cytotoxic chemotherapy is likely to be an area of research in future studies.

    2008-05-01

    Full Text Available Abstract Background The objective of this study was to evaluate the efficacy and toxicity of infusional 5-fluorouracil (5-FU, folinic acid and oxaliplatin (modified FOLFOX-6 in patients with advanced gastric cancer (AGC, as first-line palliative combination chemotherapy. We also analyzed the predictive or prognostic value of germline polymorphisms of candidate genes associated with 5-FU and oxaliplatin. Methods Seventy-three patients were administered a 2 hour infusion of oxaliplatin (100 mg/m2 and folinic acid (100 mg/m2 followed by a 46 hour continuous infusion of 5-FU (2,400 mg/m2. Genomic DNA from the patients' peripheral blood mononuclear cells was extracted. Ten polymorphisms within five genes were investigated including TS, GSTP, ERCC, XPD and XRCC. Results The overall response rate (RR was 43.8%. Median time to progression (TTP and overall survival (OS were 6.0 months and 12.6 months, respectively. Toxicities were generally tolerable and manageable. The RR was significantly higher in patients with a 6-bp deletion homozygote (-6 bp/-6 bp in TS-3'UTR (55.0% vs. 30.3% in +6 bp/+6 bp or +6 bp/-6 bp, p = 0.034, and C/A or A/A in XPD156 (52.0% vs. 26.1% in C/C, p = 0.038. The -6 bp/-6 bp in TS-3'UTR was significantly associated with a prolonged TTP and OS. In a multivariate analysis, the 6-bp deletion in TS-3'UTR was identified as an independent prognostic marker of TTP (hazard ratio = 0.561, p = 0.032. Conclusion Modified FOLFOX-6 chemotherapy appears to be active and well tolerated as first line chemotherapy in AGC patients. The 6-bp deletion in TS-3'UTR might be a candidate to select patients who are likely to benefit from 5-FU based modified FOLFOX-6 in future large scale trial.

    Full Text Available Glucocorticoids (GCs, synthetic analogues of the natural steroid hormones, are well known for their antiinflammatory and immunosuppressive properties in the periphery. They are widely and successfully used in the treatment of autoimmune diseases, chronic inflammation, and transplant rejection. Nowadays, GCs are claimed to have a beneficial role being as adjunct therapy in various infections. Different studies have been conducted to investigate their use as adjuvant therapy for different bacterial infection. This review, therefore, summarizes various bacterial infections for which glucocorticoids are reported to be used as adjuvant therapy, strategies for administration of glucocorticoids, and challenges of using glucocorticoids as adjuvant therapy.

    Background The purpose of the study was to evaluate the role of neoadjuvant chemotherapy and embolization via the anterior branches of the bilateral internal iliac arteries in treating patients with advanced ovarian epithelial carcinoma.Methods Forty-two patients with advanced ovarian epithelial carcinoma (study group) were treated via the anterior branches of the bilateral internal iliac arteries after cytoreductive surgery and 7 courses of adjuvant platinum-based combination chemotherapy. Primary cytoreductive surgery was performed in 43 patients with advanced ovarian epithelial carcinoma (control group), and then followed by 8 courses of adjuvant platinum-based combination chemotherapy. The rate of optimal cytoreductive surgery, survival rate, blood loss during operation and operative time were investigated in the two groups. Statistical significance was asessed using Student's t test, the Chi-squre test and the log-rank test. Results In the study group, the rate of optimum debulking after platinum-based chemotherapy and embolization via the anterior branches of the bilateral internal iliac arteries was 71.43%(30/42) (χ2=10.06, P0.05).Conclusions Neoadjuvant platinum-based combination chemotherapy and embolization via the anterior branches of the bilateral internal iliac arteries is an alternative treatment for patients with advanced ovarian epithelial carcinoma, in whom the chance of optimal cytoreductive surgery is low. The treatment can reduce blood loss, decrease operative time, and increase the rate of optimal cytoreductive surgery; but the median survival can't be improved significantly.

  1. Compliance and toxicity of adjuvant CMF in elderly breast cancer patients: a single-center experience

    Few data are available on compliance and safety of adjuvant chemotherapy when indicated in elderly breast cancer patients; CMF (cyclophosphamide, methotrexate, fluorouracil) can be reasonably considered the most widely accepted standard of treatment. We retrospectively reviewed compliance and safety of adjuvant CMF in patients older than 60. The treatment was indicated if patients had no severe comorbidity, a high-risk of recurrence, and were younger than 75. Toxicity was coded by NCI-CTC. Toxicity and compliance were compared between two age subgroups (<65, ≥ 65) by Fisher exact test and exact Wilcoxon rank-sum test. From March 1991 to March 2002, 180 patients were identified, 100 older than 60 and younger than 65, and 80 aged 65 or older. Febrile neutropenia was more frequent among older patients (p = 0.05). Leukopenia, neutropenia, nausea, cardiac toxicity and thrombophlebitis tended to be more frequent or severe among elderlies, while mucositis tended to be more evident among younger patients, all not significantly. Almost one half (47%) of the older patients receiving concomitant radiotherapy experienced grade 3–4 haematological toxicity. Compliance was similar in the two groups, with 6 cycles administered in 86% and 79%, day-8 chemotherapy omitted at least once in 36% and 39%, dose reduction in 27% and 38%, prolonged treatment duration (≥ 29 weeks) in 10% and 11% and need of G-CSF in 9% and 18%, among younger and older patients, respectively. Our data show that, in a highly selected population of patients 65 or more years old, CMF is as feasible as in patients older than 60 and younger than 65, but with a relevant burden of toxicity. We suggest that prospective trials in elderly patients testing less toxic treatment schemes are mandatory before indicating adjuvant chemotherapy to all elderly patients with significant risk of breast cancer recurrence

  2. Intraperitoneal P-32 for adjuvant and consolidative therapy in ovarian carcinoma

    Purpose/Objective: To determine the role of intraperitoneal radioactive chromic phosphate (P-32) in the treatment of patients with ovarian carcinoma. Survival results, patterns of recurrence, and treatment morbidity are reported for patients treated adjuvantly after primary surgery and for patients treated with the intent of consolidation after second-look laparotomy. Materials and Methods: Between 1976 and 1993, 25 patients with ovarian carcinoma were treated with 15 mCi P-32 as adjuvant therapy and 43 patients received P-32 as consolidation after second-look laparotomy. The majority of patients (13 of 19) treated adjuvantly had high-risk early-stage disease (IAG 3, IBG 2-3, IC) or more advanced stages (6 patients). Thirty-nine patients received consolidative P-32 after negative second-look laparotomy (35 Stage II-IV and 4 Stage I) and 4 Stage III patients were treated after positive second-look laparotomy. All patients had 2-year minimum follow-up (median, 7.9 years). Results: Ten-year abdominal control and cause-specific survival rates for adjuvant P-32 were 83% and 82%, respectively. For patients treated with consolidative P-32, 5-year abdominal control and cause-specific survival rates were 65% and 78%, respectively. The 5-year cause-specific survival rate for 35 patients with Stage II-IV disease treated with consolidative P-32 after negative second-look laparotomy was 81%. A component of peritoneal failure was the primary mode of recurrence (15 of 22 failures). Four patients required surgical intervention for small-bowel obstruction. No patients died of treatment-related complications. Conclusion: P-32 is well tolerated with acceptable toxicity. In comparing our results to the literature, adjuvant P-32 appears to offer improved cause-specific survival compared with observation alone and equivalent cause-specific survival compared with adjuvant chemotherapy. Consolidative P-32 after negative second-look laparotomy resulted in improved 5-year cause

  3. Survival After Chemoradiation in Resected Pancreatic Cancer: The Impact of Adjuvant Gemcitabine

    Purpose: To evaluate survival in patients with resected pancreatic cancer treated with concurrent chemoradiation with or without adjuvant gemcitabine (Gem). Methods and Materials: From 1998 to 2010, 86 patients with pancreatic adenocarcinoma who underwent resection were treated with adjuvant concurrent chemoradiation. Thirty-four patients received concurrent 5-fluorouracil–based chemoradiation (5-FU/RT) with traditional field radiation (range, 45–61.2 Gy; median, 50.4 Gy) without further adjuvant therapy. Thirty patients received traditional field 5-FU/RT (range, 45–60.4 Gy; median, 50.4 Gy) with Gem (1,000 mg/m2 weekly) either before and after radiotherapy or only after radiotherapy. Twenty-two patients received concurrent full-dose Gem (1,000 mg/m2 weekly)–based chemoradiation (Gem/RT), consisting of involved-field radiation (range, 27–38 Gy; median, 36 Gy) followed by further adjuvant Gem. Results: The median age of the cohort was 65 years (range, 40–80 years). Of the patients, 58 had T3 tumors (67%), 22 had T2 tumors (26%), and 6 had T1 tumors (7%). N1 disease was present in 61 patients (71%), whereas 18 patients (21%) had R1 resections. Performance status, lymph node status, and margin status were all similar among the treatment groups. Median follow-up was 19.0 months. Median overall survival (OS) (19.2 months, 19.0 months, and 21.0 months) and 3-year OS rates (26.5%, 27.2%, and 32.1%) were similar among patients with 5-FU/RT with no adjuvant Gem, those with 5-FU/RT with adjuvant Gem, and those with Gem/RT with adjuvant Gem, respectively (p = 0.88). Patients who received adjuvant Gem had a similar median OS (22.1 months) and 3-year OS rate (29%) compared to patients who did not (19.2 months and 26.5%, respectively) (p = 0.62). There was a trend for improved 3-year OS rates in patients with R0 vs. R1 resections (28.1% vs. 14.2%, p = 0.06) and in patients with T1 and T2 vs. T3 tumors (38% vs. 20%, p = 0.09). Node-negative patients had an improved 3

  4. CMEA cooperative trials in chemotherapy of lung cancer patients

    TA comparative analysis of the immediate and short-term results of chemo- and radiotherapy of 174 patients with well differentiated inoperable lung cancer has been performed. The data were presented by the participants of the CMEA cooperative trial (the Hungarian People's Reg public, the USSR and the Czechoslovak Socialist Republic over the period of 1976-1980). Comparative analysis has shown that the use of adjuvant chemotherapy tends to improve an immediate therapeutic effect. In well differentiated squamous cell carcinoma, a marked positive effect was obtained in 48.6% of the patients as compared to 31.2% in radiotherapy alone. However, judging by the survival rates such differences in favor of chemotherapy were not revealed. After conservative treatment (radio- and chemotherapy) of patients with differentiated lung cancer in the inoperable stage 55.7% survived for 1, 17.27% for 2, 8.55% for 3 yrs. Direct correlation between the immediate effect of radio- and chemotherapy and the survival of the patients was revealed. Of 67 patients with a marked immediate effect 49 (73.1%) lived over 1 year, 8 out of 9 patients lived for 3 yrs

    Parosteal osteosarcoma (POS) is conventionally a low-grade sarcoma with limited metastatic potential; however, the tumor occasionally transforms into a high-grade dedifferentiated POS, which commonly metastasizes to distant organs. The present report describes a rare pediatric case of conventional POS with no dedifferentiated component yet had multiple pulmonary metastases at initial diagnosis. Following limb-sparing surgery and osteosarcoma-oriented neoadjuvant chemotherapy, the patient received total resection of pulmonary metastases. Despite no treatment for pulmonary recurrence 1 year after adjuvant chemotherapy, the patient is alive with stable disease 4 years and 6 months after the initial diagnosis. PMID:27149276

  6. Complete clinical response to neoadjuvant chemotherapy in a 54-year-old male with Askin tumor.

    Mulsow, J

    2012-02-01

    Askin tumor is a tumor of the thoracopulmonary region that most commonly affects children and adolescents. These rare tumors are a form of primitive neuroectodermal tumor and typically carry a poor prognosis. Treatment is multimodal and consists of a combination of neoadjuvant chemotherapy, radical resection, and adjuvant chemo- and radiotherapy or all of the above. Surgery is advocated in most cases. We report a case of Askin tumor in a 54-year-old male who showed rapid and complete response to neoadjuvant chemotherapy. This allowed potentially radical surgery to be avoided. At one-year follow-up he remains disease-free.

    Cancer patients who start receiving chemotherapy have difficulty in understanding the state of their disease, the prognosis, and the purpose of treatment. We used a survey to evaluate the extent of perception of chemotherapy goal among cancer patients. Two hundred sixteen cancer patients who received chemotherapy for the first time participated in the study. The presence of depression and anxiety was assessed using the "Hospital Anxiety and Depression Scale" (HAD). The consistency between the patients' perception of the chemotherapy goal and the physician's perception was described as "right," and the inconsistency was described as "wrong." Among the patients who participated in the survey, 53.2 % (n = 115) were receiving adjuvant treatment and 46.8 % (n = 101) were receiving palliative treatment for metastatic disease. The rate of right and wrong perception of the chemotherapy goal was 51.9 % (n = 108) and 32.2 % (n = 67), respectively, and the rate of confused patients was 18.9 % (n = 41). The level of education was shown to be the only parameter involved in accurate perception of the treatment purpose (hazard ratio (HR) = 0.444, p = 0.025, 95 % confidence interval (CI) 0.219-0.903). In this study, there was a 51.9 % consistency between the physician's perception and that of the patient regarding the purpose of treatment. We demonstrated that the level of education was the unique factor in accurate perception of chemotherapy goal among cancer patients. PMID:25851203

    tomography (CT) in local staging of colon cancer correlated with histopathological parameters, including criteria for adjuvant chemotherapy. Material and methods. A total of 74 included patients had preoperative CT scans and surgical resection of their colon tumors. Tumor stage (T-stage), extramural tumor...... invasion (ETI), nodal stage (N-stage), extramural venous invasion (EVI) and the distance from tumor to nearest retroperitoneal fascia (DRF) were retrospectively assessed on the CT scan and compared blindly with the results of the pathological examination, including evaluation of the criteria for adjuvant...... chemotherapy. Advanced tumors were defined as T3 with ETI ≥5 mm or T4. Results. Sixty-nine percent of the tumors were correctly T-staged by CT, 7% were overstaged and 24% were understaged. As to correct recognition of ETI on the CT scan, the observer was 73% accurate compared with histology (70% sensitivity...

  15. Use of Adjuvant 5-Fluorouracil and Radiation Therapy After Gastric Cancer Resection Among the Elderly and Impact on Survival

    Purpose: In randomized trials patients with resected nonmetastatic gastric cancer who received adjuvant chemotherapy and radiotherapy (chemoRT) had better survival than those who did not. We investigated the effectiveness of adjuvant chemoRT after gastric cancer resection in an elderly general population and its effects by stage. Methods and Materials: We identified individuals in the Surveillance, Epidemiology, and End Results-Medicare database aged 65 years or older with Stage IB through Stage IV (M0) gastric cancer, from 1991 to 2002, who underwent gastric resection, using multivariate modeling to analyze predictors of chemoRT use and survival. Results: Among 1,993 patients who received combined chemoRT or no adjuvant therapy after resection, having a later year of diagnosis, having a more advanced stage, being younger, being white, being married, and having fewer comorbidities were associated with combined treatment. Among 1,476 patients aged less than 85 years who survived more than 4 months, the 313 who received combined treatment had a lower mortality rate (hazard ratio, 0.83; 95% confidence interval, 0.71-0.98) than the 1,163 who received surgery alone. Adjuvant therapy significantly reduced the mortality rate for Stages III and IV (M0), trended toward improved survival for Stage II, and showed no benefit for Stage IB. We observed trends toward improved survival in all age categories except 80 to 85 years. Conclusions: The association of combined adjuvant chemoRT with improved survival in an overall analysis of Stage IB through Stage IV (M0) resected gastric cancer is consistent with clinical trial results and suggests that, in an elderly population, adjuvant chemoradiotherapy is effective. However, our observational data suggest that adjuvant treatment may not be effective for Stage IB cancer, is possibly appropriate for Stage II, and shows significant survival benefits for Stages III and IV (M0) for those aged less than 80 years.

  16. Clinical outcomes of adjuvant radiation therapy and prognostic factors in early stage uterine cervical cancer

    To evaluate the outcomes of adjuvant radiotherapy (RT) and to analyze prognostic factors of survival in the International Federation of Gynecology and Obstetrics (FIGO) IB-IIA uterine cervical cancer. We retrospectively reviewed the medical records of 148 patients with FIGO IB-IIA uterine cervical cancer who underwent surgery followed by adjuvant RT at the Yonsei Cancer Center between June 1997 and December 2011. Adjuvant radiotherapy was delivered to the whole pelvis or an extended field with or without brachytherapy. Among all patients, 57 (38.5%) received adjuvant chemotherapy either concurrently or sequentially. To analyze prognostic factors, we assessed clinicopathologic variables and metabolic parameters measured on preoperative 18F-fluorodeoxyglucose (FDG) positron emission tomography/computed tomography (PET/CT). To evaluate the predictive performance of metabolic parameters, receiver operating characteristic curve analysis was used. Overall survival (OS) and disease-free survival (DFS) were analyzed by the Kaplan-Meier method. The median follow-up period was 63.2 months (range, 2.7 to 206.8 months). Locoregional recurrence alone occurred in 6 patients, while distant metastasis was present in 16 patients, including 2 patients with simultaneous regional failure. The 5-year and 10-year OSs were 87.0% and 85.4%, respectively. The 5-year and 10-year DFSs were 83.8% and 82.5%, respectively. In multivariate analysis, pathologic type and tumor size were shown to be significant prognostic factors associated with both DFS and OS. In subset analysis of 40 patients who underwent preoperative PET/CT, total lesion glycolysis was shown to be the most significant prognostic factor among the clinicopathologic variables and metabolic parameters for DFS. Our results demonstrated that adjuvant RT following hysterectomy effectively improves local control. From the subset analysis of preoperative PET/CT, we can consider that metabolic parameters may hold prognostic significance

  17. Survival of women with clear cell and papillary serous endometrial cancer after adjuvant radiotherapy

    Type II (papillary serous and clear cell) endometrial carcinoma (EC) is a rare subgroup and is considered to have an unfavorable prognosis. The purpose of this retrospective analysis was to elucidate the meaning of adjuvant radiotherapy (RT) for clinical outcome and to define prognostic factors in these patients (pts). From 2004-2012 forty-two pts with type II EC underwent surgery followed by adjuvant RT at our department. Median age was 72 years. The majority were early stage carcinomas (FIGO I n = 27 [64.3%], FIGO II n = 4 [9.5%], FIGO III n = 11 [26.2%]. Seven pts (16.7%) received adjuvant chemotherapy (ChT). Pts were treated with external beam radiotherapy (EBRT) and brachytherapy (IVB) boost. Five-year local recurrence free survival (LRFS), distant metastases free survival (DMFS) and overall survival (OS) were 85.4%, 78%, and 64.5% respectively. LRFS was better with lower pT stage, without lymphangiosis (L0), without haemangiosis (V0) and negative resection margins (R0). DMFS was prolonged in lymph node negatives (N0), L0, V0 and R0. OS was improved in younger pts, N0, L0, V0 and after lymphadenectomy (LNE). Multivariate analysis revealed haemangiosis (V1) as the only independent prognostic factor for OS (p = .014) and DMFS (p = .008). For LRFS pT stage remained as an independent prognostic factor (p = .028). Adjuvant RT with EBRT/IVB ensures adequate local control in type II EC, but control rates remain lower than in type I EC. A benefit of additional adjuvant ChT could not be demonstrated and a general omission of EBRT cannot be recommended at this point. Lymphovascular infiltration and pT stage might be the best predictive factors for a benefit from combined local and systemic treatment

  18. The role of adjuvants in therapeutic protection against paracoccidioidomycosis after immunization with the P10 peptide

    2012-05-01

    Full Text Available Paracoccidioidomycosis (PCM, a common chronic mycosis in Latin America, is a granulomatous systemic disease caused by the thermo-dimorphic fungus Paracoccidioides brasiliensis. The glycoprotein gp43 is the main antigen target of P. brasiliensis and a 15-mer internal peptide (QTLIAIHTLAIRYAN, known as P10, defines a major CD4+-specific T cell epitope. Previous results have indicated that, besides having a preventive role in conventional immunizations prior to challenge with the fungus, protective anti-fungal effects can be induced in P. brasiliensis-infected mice treated with P10 administered with complete Freund’s adjuvant (CFA. The peptide elicits an IFN--dependent Th1 immune response and is the main candidate for effective immunotherapy of patients with PCM, as an adjunctive approach to conventional chemotherapy. In the present study we tested the therapeutic effects of P10 combined with different adjuvants (aluminum hydroxide, CFA, flagellin and the cationic lipid dioctadecyl-dimethylammonium bromide (DODAB in BALB/c mice previously infected with the P. brasiliensis Pb18 strain. Significant reductions in the number of colony forming units (CFUs of the fungus were detected in lungs of mice immunized with P10 associated with the different adjuvants 52 days after infection. Mice treated with DODAB and P10, followed by mice treated with P10 and flagellin, showed the most prominent effects as demonstrated by the lowest numbers of viable yeast cells as well as reductions in granuloma formation and fibrosis. Concomitantly, secretion of IFN- and TNF-, in contrast to IL-4 and IL-10, was enhanced in the lungs of mice immunized with P10 in combination with the tested adjuvants, with the best results observed in mice treated with P10 and DODAB. In conclusion, the present results demonstrate that the co-administration of the synthetic P10 peptide with several adjuvants, particularly DODAB, have significant therapeutic effects in experimental

  1. Adjuvant interferon treatment for melanoma.

    Agarwala, S S; Kirkwood, J M

    1998-08-01

    After decades of research, the adjuvant therapy of patients with melanoma has recently shown significant survival and relapse-free interval benefit for the intravenous and subcutaneous administration of maximally tolerable dosages of recombinant IFN alpha 2b in a trial conducted by the ECOG (E1684). Despite the toxicity of this therapy, retrospective analyses of its impact upon quality-of-life using Q-TWiST methods and cost-efficacy analyses all argue for the benefit and utility of this intervention, especially for node-positive patients with resectable melanoma at highest risk of relapse. A confirmatory trial has been completed and will mature in the spring of 1998. The impact of lower dosages of IFN, apparent transiently during and for a period of time following treatment has not been sustained with longer follow-up in a number of trials. Current approaches in Europe and North America focus upon refinement of dose and duration of treatment with IFN and their potential interactions with, and comparison with, active specific immunotherapy with vaccines. A recently emerging area of research is the patient with stage IIA melanoma and the potential role of an abbreviated high-dose regimen of IFN alpha in this patient subset. PMID:9759581

    2006-01-01

    Full Text Available Background: For inoperable non-small cell lung cancer combined chemotherapy and radiotherapy plays an important role as a therapeutic modality. The aim of the present study was to analyze neoadjuvant chemotherapy related acute toxicity in locally advanced lung cancer (stage IIIA and IIIB in Indian patients using Cisplatin and Etoposide combination chemotherapy. Material and methods: Forty patients of locally advanced Non small cell lung cancer received three cycles neoadjuvant chemotherapy using Injection Cisplatin and Etoposide. The patients were taken for Radical radiotherapy to a dose of 60 Gray over 30 fractions in conventional fractionation after completing chemotherapy. Chemotherapy associated toxicity was assessed using common toxicity criteria (CTC v2.0 Results: Forty patients were available for final evaluation. Median age of presentation of patients was fifty-six years. Thirteen patients had Non small cell lung cancer stage IIIA while twenty-seven patients had Stage IIIB disease. Anemia was the most common hematological toxicity observed (seen in 81% of patients. Nausea and vomiting were the most common non -hematological toxicity seen. Sensory neuropathy was seen in 38%of patients. 88% patients developed alopecia. Seven patients developed febrile neutropenias. Conclusion: Neo-adjuvant chemotherapy using Cisplatin and Etoposide continues to be a basic regimen in the Indian set up despite availability of higher molecules, since it is cost effective, well tolerated and therapeutically effective. Blood transfusions, growth factors and supportive care can be used effectively to over come toxicity associated with this regimen.

    The emergence of pandemic H1N1 influenza viruses in April 2009 and the continuous evolution of highly pathogenic H5N1 influenza viruses underscore the urgency of novel approaches to chemotherapy for human influenza infection. Anti-influenza drugs are currently limited to the neuraminidase inhibitors (oseltamivir and zanamivir) and to M2 ion channel blockers (amantadine and rimantadine), although resistance to the latter class develops rapidly. Potential targets for the development of new anti...

    AIM: To evaluate the efficacy and toxicity of postoperative chemoradiation using FP chemotherapy and oral capecitabine during radiation for advanced gastric cancer following curative resection.METHODS: Thirty-one patients who had underwent a potentially curative resection for Stage Ⅲ and Ⅳ (MO) gastric cancer were enrolled. Therapy consists of one cycle of FP (continuous infusion of 5-FU 1000 mg/m2 on d 1 to 5 and cisplatin 60 mg/m2 on d 1) followed by 4500 cGy (180 cGy/d) with capecitabine (1650 mg/m2 daily throughout radiotherapy). Four wk after completion of the radiotherapy, patients received three additional cycles of FP every three wk. The median follow-up duration was 22.2 mo.RESULTS: The 3-year disease free and overall survival in this study were 82.7% and 83.4%, respectively. Four patients (12.9%) showed relapse during follow-up. Eight patients did not complete all planned adjuvant therapy.Grade 3/4 toxicities included neutropenia in 50.2%, anemia in 12.9%, thrombocytopenia in 3.2% and nausea/vomiting in 3.2%. Neither grade 3/4 hand foot syndrome nor treatment related febrile neutropenia or death were observed.CONCLUSION: These preliminary results suggest that this postoperative adjuvant chemoradiation regimen of FP before and after capecitabine and concurrent radiotherapy appears well tolerated and offers a comparable toxicity profile to the chemoradiation regimen utilized in INT-0116. This treatment modality allowed successful loco-regional control rate and 3-year overall survival.

  8. Postoperative Chemotherapy Followed by Conformal Concomitant Chemoradiotherapy in High-Risk Gastric Cancer

    Purpose: To analyze the efficacy, toxicity, and pattern of relapse after adjuvant cisplatin-based chemotherapy followed by three-dimensional irradiation and concomitant LV5FU2 chemotherapy (high-dose leucovorin and 5-fluorouracil bolus plus continuous infusion) in the treatment of completely resected high-risk gastric cancer. Methods and Materials: This was a retrospective analysis of 52 patients with high-risk gastric cancer initially treated by total/partial gastrectomy and lymphadenectomy between January 2002 and June 2007. Median age was 54 years (range, 36–75 years). Postoperative treatment consisted of 5-fluorouracil and cisplatin chemotherapy. Adjuvant chemotherapy was followed by three-dimensional conformal radiotherapy in the tumor bed and regional lymph nodes at 4500 cGy/25 fractions in association with concomitant chemotherapy. Concomitant chemotherapy consisted of a 2-h infusion of leucovorin (200 mg/m²) followed by a bolus of 5-fluorouracil (400 mg/m²) and then a 44-h continuous infusion of 5-fluorouracil (2400–3600 mg/m²) given every 14 days, for three cycles (LV5FU2 protocol). Results: Five-year overall and disease-free survival were 50% and 48%, respectively. Distant metastases and peritoneal spread were the most frequent sites of relapse (37% each). After multivariate analysis, only pathologic nodal status was significantly associated with disease-free and overall survival. Acute toxicities were essentially gastrointestinal and hematologic. One myocardial infarction and one pulmonary embolism were also reported. Eighteen patients had a radiotherapy program interruption because of acute toxicity. All patients but 2 have completed radiotherapy. Conclusion: Postoperative cisplatin-based chemotherapy followed by conformal radiotherapy in association with concurrent 5-fluorouracil seemed to be feasible and resulted in successful locoregional control.

  10. Prospective phase II study of preoperative short-course radiotherapy for rectal cancer with twice daily fractions of 2.9 Gy to a total dose of 29 Gy - Long-term results

    To evaluate clinical outcome after preoperative short-course radiotherapy for rectal cancer with twice daily fractions of 2.9 Gy to a total dose of 29 Gy and adjuvant chemotherapy for pathological stage UICC ≥ II. 118 patients (median age 64 years; male : female ratio 2.5 : 1) with pathological proven rectal cancer (clinical stage II 50%, III 41.5%, IV 8.5%) were treated preoperatively with twice daily radiotherapy of 2.9 Gy single fraction dose to a total dose of 29 Gy; surgery was performed immediately in the following week with total mesorectal excision (TME). Adjuvant 5-FU based chemotherapy was planned for pathological stage UICC ≥ II. After low anterior resection (70%) and abdominoperineal resection (30%), pathology showed stage UICC I (27.1%), II (25.4%), III (37.3%) and IV (9.3%). Perioperative mortality was 3.4% and perioperative complications were observed in 22.8% of the patients. Adjuvant chemotherapy was given in 75.3% of patients with pathological stage UICC ≥ II. After median follow-up of 46 months, five-year overall survival was 67%, cancer-specific survival 76%, local control 92% and freedom from systemic progression 75%. Late toxicity > grade II was observed in 11% of the patients. Preoperative short-course radiotherapy, total mesorectal excision and adjuvant chemotherapy for pathological stage UICC ≥ II achieved excellent local control and favorable survival

  11. Efficacy and Interaction of Antioxidant Supplements as Adjuvant Therapy in Cancer Treatment: A Systematic Review.

    2016-03-01

    Oxidative stress is a key component in carcinogenesis. Although radiation produces reactive oxygen species, some anticancer agents such as alkylating agents, platinum and antitumor antibiotics exert cytotoxicity by generating free radicals. Nonenzymatic exogenous antioxidants such as vitamins, minerals, and polyphenols can quench ROS activity. However, whether antioxidants alter antitumor effects during radiotherapy and some types of chemotherapy remains unclear. In the present study, we reviewed antioxidants as an adjuvant therapy for cancer patients during chemotherapy or radiotherapy. Electronic literature searches were performed to select all randomized controlled clinical trials (RCTs) in which antioxidants were administered to cancer patients along with chemotherapy or radiotherapy. Articles or abstracts written in English were included. In total, 399 reports received primary screening. Duplicated articles and those meeting the exclusion criteria (not RCT, not human, and no oral administration) were excluded. Finally, 49 reports matching the inclusion criteria were included. It was difficult to determine whether antioxidants affect treatment outcomes or whether antioxidants ameliorate adverse effects induced by chemotherapy and radiotherapy. It is desirable to use an evidence-based method to select supplements best suited to cancer patients. Although there are many opinions about risks or benefits of antioxidant supplementation, we could mostly conclude that the harm caused by antioxidant supplementation remains unclear for patients during cancer therapy, except for smokers undergoing radiotherapy.

    cancer cells of 30 patients with advanced gastric cancer who underwent surgical treatment. Correlation between test results, clinical and anatomopathological aspects, disease staging, were dane using the same methodology of study performed in Japanese patients presented in master dissertation. METHODS: MTT test was carried out in cancer cells of 30 patients with gastric adenocarcinoma submitted to surgical treatment in the Department of Surgery at Santa Casa de São Paulo, Medical School. The following drugs were studied in vitro: mitomycin C, doxorubicin, cisplatin and 5-fluorouracil. RESULTS: Efficacy rates on tumors cells were reported as being: 16.6% for mitomycin C, 10.0 % for doxorubicin, 6.6% for cisplatin and 6.6% for 5-fluorouracil. There were no statistically significant correlations between chemosensitivity and age, sex, microscopic aspect and disease staging (p0.05. CONCLUSION: The effect of the studied chemotherapeutical drugs on gastric cancer cell cultivated in vitro is low. The results of chemotherapy effect in vitro proved no statistical correlation with age, sex, microscopic aspect and disease staging of these patients. Using the same methodology in our patients (non oriental or in Japanese patients the chemosensitivity was low in both studies. We can conclude that no matter which race is studied it will get the same low response results of chemosensitivity. With development of new chemotherapeutics agents the expectation is greater for better results in clinical practice. With the utilization and the spread of the MTT chemosensitivity test in our patients it will be possible to create protocols and multicentric studies for selection of new chemotherapeutic agents.

    Vaccines require optimal adjuvants including immunopotentiator and delivery systems to offer long term protection from infectious diseases in animals and man. Initially it was believed that adjuvants are responsible for promoting strong and sustainable antibody responses. Now it has been shown that adjuvants influence the isotype and avidity of antibody and also affect the properties of cell-mediated immunity. Mostly oil emulsions, lipopolysaccharides, polymers, saponins, liposomes, cytokines,ISCOMs (immunostimulating complexes), Freund's complete adjuvant, Freund's incomplete adjuvant, alums, bacterial toxins etc.,are common adjuvants under investigation. Saponin based adjuvants have the ability to stimulate the cell mediated immune system as well as to enhance antibody production and have the advantage that only a low dose is needed for adjuvant activity. In the present study the importance of adjuvants, their role and the effect of saponin in immune system is reviewed.

  14. Safety, feasibility and effects of an individualised walking intervention for women undergoing chemotherapy for ovarian cancer: a pilot study

    Exercise interventions during adjuvant cancer therapy have been shown to increase functional capacity, relieve fatigue and distress and may assist rates of chemotherapy completion. These studies have been limited to breast, gastric and mixed cancer groups and it is not yet known if a similar intervention is even feasible among women with ovarian cancer. We aimed to assess safety, feasibility and potential effect of a walking intervention in women undergoing chemotherapy for ovarian cancer. Women newly diagnosed with ovarian cancer were recruited to participate in an individualised walking intervention throughout chemotherapy and were assessed pre- and post-intervention. Feasibility measures included session adherence, compliance with exercise physiologist prescribed walking targets and self-reported program acceptability. Changes in objective physical functioning (6-minute walk test), self-reported distress (Hospital Anxiety and Depression Scale), symptoms (Memorial Symptom Assessment Scale - Physical) and quality of life (Functional Assessment of Cancer Therapy - Ovarian) were calculated, and chemotherapy completion and adverse intervention effects recorded. Seventeen women were enrolled (63% recruitment rate). Mean age was 60 years (SD = 8 years), 88% were diagnosed with FIGO stage III or IV disease, 14 women underwent adjuvant and three neo-adjuvant chemotherapy. On average, women adhered to > 80% of their intervention sessions and complied with 76% of their walking targets, with the majority walking four days a week at moderate intensity for 30 minutes per session. Meaningful improvements were found in physical functioning, physical symptoms, physical well-being and ovarian cancer-specific quality of life. Most women (76%) completed ≥85% of their planned chemotherapy dose. There were no withdrawals or serious adverse events and all women reported the program as being helpful. These positive preliminary results suggest that this walking intervention for women

  15. Radiation Therapy Is Associated With Improved Survival in the Adjuvant and Definitive Treatment of Intrahepatic Cholangiocarcinoma

    Purpose: Intrahepatic cholangiocarcinomas (IHC) are rare tumors for which large randomized studies regarding the use of radiation are not available. The purpose of this study was to examine the role of adjuvant and definitive radiation therapy in the treatment of IHC in a large group of patients. Methods and Materials: This is a retrospective analysis of 3,839 patients with IHC collected from the Surveillance, Epidemiology, and End Results (SEER) database. The primary endpoint was overall survival (OS). Results: Patients received either surgery alone (25%), radiation therapy alone (10%), surgery and adjuvant radiation therapy (7%) or no treatment (58%). The median age of the patient population was 73 years (range, 22-102 years); 52% of patients were male and 81% were Caucasian. Median OS was 11 (95% confidence interval [CI], 9-13), 6 (95% CI, 5-6), 7 (95% CI, 6-8), and 3 months for surgery and adjuvant radiation therapy, sugery alone, radiation therapy alone, and no treatment, respectively. The OS was significantly different between surgery alone and surgery and adjuvant radiation therapy (p = 0.014) and radiation therapy alone and no treatment (p < 0.0001). Use of surgery and adjuvant radiation therapy conferred the greatest benefit on OS (HR = 0.40; 95% CI, 0.34-0.47), followed by surgery alone (hazard ratio [HR], 0.49; 95% CI, 0.44-0.54) and radiation therapy alone (HR, 0.68; 95% CI, 0.59-0.77) compared with no treatment, on multivariate analysis. Propensity score adjusted hazard ratios (controlling for age, race/ethnicity, stage, and year of diagnosis) were also significant (surgery and adjuvant radiation therapy vs. surgery alone (HR, 0.82; 95% CI, 0.70-0.96); radiation therapy alone vs. no treatment (HR, 0.67; 95% CI, 0.58-0.76)). Conclusions: The study results suggest that adjuvant and definitive radiation treatment prolong survival, although cure rates remain low. Future studies should evaluate the addition of chemotherapy and biologics to the treatment of

  16. A cost-effectiveness analysis of adjuvant therapies for resected adenocarcinoma of the rectum

    PURPOSE: Several prospective randomized trials have shown a significant survival advantage with adjuvant chemotherapy and radiation therapy following surgical resection of adenocarcinoma of the rectum. Recent and ongoing trials are evaluating the role of modulated and/or protracted venous infusion [PVI] chemotherapy with pelvic irradiation [PRT]. The economic implications of additional therapies compared with their incremental benefits have not been rigorously analyzed. This study attempts to assess the incremental cost effectiveness of adjuvant therapy over surgery alone, and secondly, adjuvant therapy with PVI delivery systems versus rapid infusion. METHODS: A Markov model was constructed to describe the natural history of rectal carcinoma [stage B2, C] following surgical resection in a hypothetical cohort of 60 year old patients. This model was used to perform two sets of comparisons: [1] surgery alone versus adjuvant bolus fluorouracil [5-FU] with PRT, and [2] bolus 5-FU with PRT versus PVI 5-FU with PRT. Relapse rates and overall survival were derived from an early GITSG trial for the first comparison and from the NCCTG 86-47-51 trial for the second comparison. Medicare reimbursement rates and reports from health maintenance organizations were used to obtain net medical costs of adjuvant treatments, routine follow-up, advanced recurrent disease, and terminal illness as a result of rectal carcinoma. Total years of life and medical costs were projected over an 8-year time horizon for the first comparison [GITSG data] and over a 5-year time horizon for the second comparison [NCCTG data]. Monetary and nonmonetary benefits were discounted at 5% per year. Adjustments for quality of life, costs of adverse effects from treatment, and indirect costs of disease or treatment were not included in this current analysis. RESULTS: The main survival and economic outcomes for each treatment arm in the two comparisons are reported in the table below. For the first comparison

  17. Distant Metastasis Risk Stratification for Patients Undergoing Curative Resection Followed by Adjuvant Chemoradiation for Extrahepatic Bile Duct Cancer

    Purpose: To analyze the prognostic factors predicting distant metastasis in patients undergoing adjuvant chemoradiation for extrahepatic bile duct (EHBD) cancer. Methods and Materials: Between January 1995 and August 2006, 166 patients with EHBD cancer underwent resection with curative intent, followed by adjuvant chemoradiation. There were 120 males and 46 females, and median age was 61 years (range, 34–86). Postoperative radiotherapy was delivered to tumor bed and regional lymph nodes (median dose, 40 Gy; range, 34–56 Gy). A total of 157 patients also received fluoropyrimidine chemotherapy as a radiosensitizer, and fluoropyrimidine-based maintenance chemotherapy was administered to 127 patients. Median follow-up duration was 29 months. Results: The treatment failed for 97 patients, and the major pattern of failure was distant metastasis (76 patients, 78.4%). The 5-year distant metastasis-free survival rate was 49.4%. The most common site of distant failure was the liver (n = 36). On multivariate analysis, hilar tumor, tumor size ≥2 cm, involved lymph node, and poorly differentiated tumor were associated with inferior distant metastasis-free survival (p = 0.0348, 0.0754, 0.0009, and 0.0078, respectively), whereas T stage was not (p = 0.8081). When patients were divided into four groups based on these risk factors, the 5-year distant metastasis-free survival rates for patients with 0, 1, 2, and 3 risk factors were 86.4%, 59.9%, 32.5%, and 0%, respectively (p < 0.0001). Conclusion: Despite maintenance chemotherapy, distant metastasis was the major pattern of failure in patients undergoing adjuvant chemoradiation for EHBD cancer after resection with curative intent. Intensified chemotherapy is warranted to improve the treatment outcome, especially in those with multiple risk factors.

  18. Beyond antigens and adjuvants: formulating future vaccines.

    Moyer, Tyson J; Zmolek, Andrew C; Irvine, Darrell J

    2016-03-01

    The need to optimize vaccine potency while minimizing toxicity in healthy recipients has motivated studies of the formulation of vaccines to control how, when, and where antigens and adjuvants encounter immune cells and other cells/tissues following administration. An effective subunit vaccine must traffic to lymph nodes (LNs), activate both the innate and adaptive arms of the immune system, and persist for a sufficient time to promote a mature immune response. Here, we review approaches to tailor these three aspects of vaccine function through optimized formulations. Traditional vaccine adjuvants activate innate immune cells, promote cell-mediated transport of antigen to lymphoid tissues, and promote antigen retention in LNs. Recent studies using nanoparticles and other lymphatic-targeting strategies suggest that direct targeting of antigens and adjuvant compounds to LNs can also enhance vaccine potency without sacrificing safety. The use of formulations to regulate biodistribution and promote antigen and inflammatory cue co-uptake in immune cells may be important for next-generation molecular adjuvants. Finally, strategies to program vaccine kinetics through novel formulation and delivery strategies provide another means to enhance immune responses independent of the choice of adjuvant. These technologies offer the prospect of enhanced efficacy while maintaining high safety profiles necessary for successful vaccines. PMID:26928033

  19. Synthetic Self-Adjuvanting Glycopeptide Cancer Vaccines

    Payne, Richard; McDonald, David; Byrne, Scott

    2015-10-01

    Due to changes in glycosyltransferase expression during tumorigenesis, the glycoproteins of cancer cells often carry highly truncated carbohydrate chains compared to those on healthy cells. These glycans are known as tumor-associated carbohydrate antigens, and are prime targets for use in vaccines for the prevention and treatment of cancer. Herein, we review the state-of-the-art in targeting the immune system towards tumor-associated glycopeptide antigens via synthetic self adjuvanting vaccines, in which the antigenic and adjuvanting moieties of the vaccines are present in the same molecule. The majority of the self-adjuvanting glycopeptide cancer vaccines reported to date employ antigens from mucin 1, a protein which is highly over-expressed and aberrantly glycosylated in many forms of cancer. The adjuvants used in these vaccines predominantly include lipopeptide- or lipoamino acid-based TLR2 agonists, although studies investigating stimulation of TLR9 and TLR4 are also discussed. Most of these adjuvants are highly lipophilic, and, upon conjugation to antigenic peptides, provide amphiphilic vaccine molecules. The amphiphilic nature of these vaccine constructs can lead to the formation of higher-order structures by vaccines in solution, which are likely to be important for their efficacy in vivo.

  20. Korean medicine therapy as a substitute for chemotherapy for metastatic breast cancer: a case report.

    Lee, Dong-Hyun; Kim, Sung-Su; Seong, Shin; Kim, Nari; Han, Jae-Bok

    2015-01-01

    A 46-year-old Korean woman was diagnosed with stage III breast cancer and underwent 8 cycles of neoadjuvant chemotherapy, breast conservation surgery and adjuvant radiotherapy. However, the cancer recurred in the right upper lung (RUL) and the right pulmonary hilum after 8 months. The RUL nodule was removed through a wedge resection, and the pathologic finding was revealed as a metastatic adenocarcinoma. Adjuvant chemotherapy was recommended, but she refused it because she feared adverse reactions to chemotherapy. Instead, Korean Medicine Therapy with intravenous wild ginseng pharmacopuncture (WGP), Cordyceps sinensis pharmacopuncture, Trichosanthes kirilowii pharmacopuncture, Euonymus alatus pharmacopuncture (EAP) and Astragalus membranaceus pharmacopuncture was started. After a month, the disease looked stable, but findings of newly occurring metastatic lymphadenopathies appeared on CT after 6 months. Salvage chemotherapy was recommended, but she also refused it. At this time, Prunella vulgaris pharmacopuncture was started. Finally, a complete resolution was confirmed on PET-CT after 5 months, and she has remained in stable condition for more than 6 months with WGP, EAP, a Soram nebulizer solution inhalation and the oral intake of Soramdan S and Hangamdan S.

    Liu, Haiguang; Lv, Lin; Yang, Kai

    2015-01-01

    Conventional chemotherapy is the main treatment for cancer and benefits patients in the form of decreased relapse and metastasis and longer overall survival. However, as the target therapy drugs and delivery systems are not wholly precise, it also results in quite a few side effects, and is less efficient in many cancers due to the spared cancer stem cells, which are considered the reason for chemotherapy resistance, relapse, and metastasis. Conventional chemotherapy limitations and the cance...

    Chemotherapy has become a third major treatment option for patients with brain tumors, in addition to surgery and radiotherapy. The role of chemotherapy in the treatment of gliomas is no longer limited to recurrent disease. Temozolomide has become the standard of care in newly diagnosed glioblastoma.

    2007-08-01

    Full Text Available Abstract Background A complete pathological response to neo-adjuvant chemo-radiation for oesophageal cancer is associated with favourable survival. However, such a benefit is seen in the minority. If one could identify, at diagnosis, those patients who were unlikely to respond unnecessary toxicity could be avoided and alternative treatment can be considered. The aim of this review was to highlight predictive markers currently assessed and evaluate their clinical utility. Methods A systematic search of Pubmed and Google Scholar was performed using the following keywords; "neo-adjuvant", "oesophageal", "trimodality", "chemotherapy", "radiotherapy", "chemoradiation" and "predict". The original manuscripts were sourced for further articles of relevance. Results Conventional indices including tumour stage and grade seem unable to predict histological response. Immuno-histochemical markers have been extensively studied, but none has made its way into routine clinical practice. Global gene expression from fresh pre-treatment tissue using cDNA microarray has only recently been assessed, but shows considerable promise. Molecular imaging using FDG-PET seems to be able to predict response after neo-adjuvant chemoradiation has finished, but there is a paucity of data when such imaging is performed earlier. Conclusion Currently there are no clinically useful predictors of response based on standard pathological assessment and immunohistochemistry. Genomics, proteomics and molecular imaging may hold promise.

  5. Risk of endocrine pancreatic insufficiency in patients receiving adjuvant chemoradiation for resected gastric cancer

    Background: Adjuvant radiotherapy combined with 5-fluorouracil based chemotherapy has become the new standard after curative resection in high risk gastric cancer. Beside many complications due to surgery, the addition of chemotherapy and radiotherapy as adjuvant treatment may lead to both acute and late toxicities. Pancreatic tissue irradiation during this adjuvant treatment because of incidental and unavoidable inclusion of the organ within the radiation field may affect exocrine and endocrine functions of the organ. Materials and methods: Fifty-three patients with gastric adenocarcinoma were evaluated for adjuvant chemoradiotherapy after surgery. While 37 out of 53 patients were treated postoperatively due to either serosal or adjacent organ or lymph node involvement, 16 patients without these risk factors were followed up regularly without any additional treatment and they served as the control group. Fasting blood glucose (FBG), hemoglobin A1c (HBA1c), insulin and C-peptide levels were measured in the control and study groups after the surgery and 6 months and 1 year later. Results: At the baseline there was no difference in FBG, HbA1c, C-peptide and insulin levels between the control and the study groups. At the end of the study there was a statistically significant decline in insulin and C-peptide levels in the study group, (7.5 ± 6.0 vs 4.5 ± 4.4 IU/L, p: 0.002 and 2.3 ± 0.9 vs 1.56 ± 0.9 ng/ml, p: 0.001) respectively. Conclusions: Adjuvant radiotherapy in gastric cancer leads to a decrease in beta cell function and insulin secretion capacity of the pancreas with possible diabetes risk. Radiation-induced pancreatic injury and late effects of radiation on normal pancreatic tissue are unknown, but pancreas is more sensitive to radiation than known. This organ should be studied extensively in order to determine the tolerance doses and it should be contoured during abdominal radiotherapy planning as an organ at risk

    Full Text Available Pemphigus vulgaris (PV is a life threatening autoimmune blistering disease of skin and mucous membranes. Advent of systemic steroids has greatly reduced the mortality rate. However, steroids and adjuvant immunosuppressive therapy are nowadays frequent contributory agents of morbidity and mortality of PV. Mycophenolate mofetil (MMF has been reported to be an effective adjuvant to systemic steroids. It helps in increasing the immunosuppressive effect and minimizing the toxicities by steroid sparing effect. However, its efficacy in refractory cases of PV is not well documented. The lowest possible dose with satisfactory therapeutic efficacy and least side effects is known. We used MMF 1 g/day and systemic steroids in 3 Indian patients with pemphigus vulgaris who were resistant to systemic steroid monotherapy or combination treatment with azathioprine. In our experience, MMF offers an effective adjuvant with minimal side-effects in the treatment of resistant PV.

  8. Enhanced antitumor effect and mechanism of chemotherapy combined with low dose radiation

    It is well known that whole body irradiation (WBI) with low dose X-rays could improve the function of the immunological system and the antitumor efficacy of local large dose irradiation. In order to study the adjuvant effect of WBI with low dose on the tumor suppressive effect of chemotherapy, 6 hours before mitomycin C or cyclophosphamide I.P. administration, WBI with 75 mGy was given to C57BL/6 mice bearing Lewis Lung carcinoma. It was found that WBI with 75 mGy X-rays could markedly enhanced the suppressive effect of chemotherapy on tumor and significantly increase some immunological parameters related to tumor killing. The results suggested that WBI with 75 mGy X-rays could reduce the immunological damage of tumor-bearing mice caused by chemotherapy and enhance the antitumor efficacy of cytotoxic agents

    The aim of this study was to evaluate the efficacy of adjuvant chemoradiotherapy following surgery in patients with advanced esophageal cancer. We followed the cases of 57 such patients treated at our hospital, involving 19 who received adjuvant chemoradiotherapy (CR group), 19 who received radiotherapy alone (R group), and 19 who did received neither (N group). In the CR group, chemotherapy, consisting of cis-diaminodichloroplatinum (CDDP), 5-fluorouracil (5-FU), and etoposide (VP-16), was combined with radiotherapy was administered from 4 weeks after surgery. Concurrent radiotherapy was started at 3 weeks after esophagectomy. CDDP at 50 mg/m{sup 2} was administered on days 1 and 7.5-FU at 500 mg/m{sup 2} and VP-16 at 60 mg/m{sup 2} were administered on days 3, 4, and 5. Thirteen patients (68.4%) were treated with more than 2 cycles of chemotherapy combined with radiation. Side-effects of severe anorexia (grade 3) and leukocytopenia (<1900/{mu}l) were observed in 47% and 39% of the patients, respectively. However no treatment-related death was observed. The 5-year-survival rate was 25.2%, 18.9%, and 15.8%, in the CR group, R group, and N group, respectively. The recurrence rate was 66.7% in the CR group, which was higher than in the matched control groups (46.2% in the N group and 54.5% in the R group), but with no significant difference. These results suggested that adjuvant chemoradiotherapy did not contribute to improvement in prognosis for these patients with advanced esophageal cancer. (author)

    In breast cancer patients, primary chemotherapy is associated with the same survival benefits as adjuvant chemotherapy. Residual tumors represent a clinical challenge, as they may be resistant to additional cycles of the same drugs. Our aim was to identify differential transcripts expressed in residual tumors, after neoadjuvant chemotherapy, that might be related with tumor resistance. Hence, 16 patients with paired tumor samples, collected before and after treatment (4 cycles doxorubicin/cyclophosphamide, AC) had their gene expression evaluated on cDNA microarray slides containing 4,608 genes. Three hundred and eighty-nine genes were differentially expressed (paired Student's t-test, pFDR<0.01) between pre- and post-chemotherapy samples and among the regulated functions were the JNK cascade and cell death. Unsupervised hierarchical clustering identified one branch comprising exclusively, eight pre-chemotherapy samples and another branch, including the former correspondent eight post-chemotherapy samples and other 16 paired pre/post-chemotherapy samples. No differences in clinical and tumor parameters could explain this clustering. Another group of 11 patients with paired samples had expression of selected genes determined by real-time RT-PCR and CTGF and DUSP1 were confirmed more expressed in post- as compared to pre-chemotherapy samples. After neoadjuvant chemotherapy some residual samples may retain their molecular signature while others present significant changes in their gene expression, probably induced by the treatment. CTGF and DUSP1 overexpression in residual samples may be a reflection of resistance to further administration of AC regimen. PMID:19724859

  11. Clinical efficacy of local targeted chemotherapy for triple-negative breast cancer

    The aim of the study was to evaluate the clinical efficacy of superselective intra-arterial targeted neo-adjuvant chemotherapy in the treatment of estrogen receptor (ER)-negative, progesterone receptor (PR)-negative, and human epidermal growth factor receptor 2 (HER2)-negative (triple-negative) breast cancer. A total of 47 triple-negative breast cancer patients (29 at stage II, 13 at stage III and 5 at stage IV) were randomly assigned to two groups: targeted chemotherapy group (n=24) and control group (n=23). Patients in the targeted chemotherapy group received preoperative superselective intra-arterial chemotherapy with CEF regimen (C: cyclophosphamide [600 mg/m2]; E: epirubicin [90 mg/m2]; F: 5-fluorouracil [600 mg/m2]), and those in the control group received routine neoadjuvant chemotherapy with CEF. The duration of the treatment, changes in lesions and the prognosis were determined. The average course of the treatment was 15 days in the targeted chemotherapy group which was significantly shorter than that in the control group (31 days) (P<0.01). The remission rate of lesions was 91.6% in the targeted chemotherapy group and 60.9% in the control group, respectively. Among these patients, 9 died within two years, including 2 (both at IV stage) in the targeted chemotherapy group and 7 (2 at stage II, 4 at stage III and 1 at stage IV) in the control group. As an neoadjuvant therapy, the superselective intra-arterial chemotherapy is effective for triple-negative breast cancer, with advantages of the short treatment course and favourable remission rates as well as prognoses

  12. The effects of sequence and type of chemotherapy and radiation therapy on cosmesis and complications after breast conservation therapy

    Purpose: Chemotherapy plays an increasingly important role in the treatment of both node-negative and node-positive breast cancer patients, but the optimal sequencing of chemotherapy and radiation therapy is not well established. The purpose of this study is to evaluate the interaction of sequence and type of chemotherapy and hormonal therapy given with radiation therapy on the cosmetic outcome and the incidence of complications of Stage I and II breast cancer patients treated with breast-conserving therapy. Methods and Materials: The records of 1053 Stage I and II breast cancer patients treated with curative intent with breast-conserving surgery, axillary dissection, and radiation therapy between 1977-1991 were reviewed. Median follow-up after treatment was 6.7 years. Two hundred fourteen patients received chemotherapy alone, 141 patients received hormonal therapy alone, 86 patients received both, and 612 patients received no adjuvant therapy. Patients who received chemotherapy ± hormonal therapy were grouped according to sequence of chemotherapy: (a) concurrent = concurrent chemotherapy with radiation therapy followed by chemotherapy; (b) sequential = radiation followed by chemotherapy or chemotherapy followed by radiation; and (c) sandwich = chemotherapy followed by concurrent chemotherapy and radiation followed by chemotherapy. Compared to node negative patients, node-positive patients more commonly received chemotherapy (77 vs. 9%, p < 0.0001) and/or hormonal therapy (40 vs. 14%, p < 0.0001). Among patients who received chemotherapy, the majority (243 patients) received concurrent chemotherapy and radiation therapy with two cycles of cytoxan and 5-fluorouracil (5-FU) administered during radiation followed by six cycles of chemotherapy with cytoxan, 5-fluorouracil and either methotrexate(CMF) or doxorubicin(CAF). For analysis of cosmesis, patients included were relapse free with 3 years minimum follow-up. Results: The use of chemotherapy had an adverse effect

    Full Text Available CONTEXT AND AIM: The prognosis of primary gliosarcoma (PGS remains dismal with current treatment modalities. We analyzed the outcome of PGS patients treated with concurrent and adjuvant temozolomide (TMZ. SETTINGS AND DESIGN: Retrospective single institutional analysis. MATERIALS AND METHODS: We retrospectively evaluated 27 patients of PGS treated with radiotherapy (RT and TMZ during 2007-2012. STATISTICAL ANALYSIS USED: Overall survival (OS was estimated by the use of Kaplan Meier method and toxicities were evaluate using common terminology criteria for adverse events version 2.0 (National Cancer Institute, USA. RESULTS: Median age at presentation and Karnofsky performance status was 45 years and 90 respectively and male: female ratio was 20:7. Patients received adjuvant RT to a total dose of 60 Gy at 2 Gy/fraction. All patients except 5 received adjuvant TMZ to a median number of 6 cycles. Grade 2 and 3 hematological toxicity was seen in 8% and 4% of patients respectively during concurrent RT. During adjuvant chemotherapy, 13.6% had Grade 3 thrombocytopenia and 9.5% had Grade 3 neutropenia. Median OS was 16.7 months (1 year and 2 year actuarial OS was 70.8% and 32.6% respectively. Adjuvant TMZ was associated with a better survival (median survival 21.21 vs. 11.93 months; P = 0.0046 on univariate analysis and also on multivariate analysis (hazard ratio 1.82, 95% confidence interval: 1.503-25.58; P = 0.012. CONCLUSIONS: The results of our study, largest series of patients with PGS treated with concurrent and adjuvant TMZ shows an impressive survival with acceptable toxicity. We suggest TMZ be included in the “standard of care” for this tumor.

  14. Maintenance chemotherapy after chemoradiation improves survival of patients with locally advanced pancreatic carcinoma. A retrospective analysis of prospectively recruited patients

    Background and purpose: currently, there is no treatment standard for patients with locally advanced pancreatic cancer (PaCa) after chemoradiation. The aim of the present study was to retrospectively assess overall survival and toxicity of chemotherapy in addition to chemoradiation in this patient group. Patients and methods: three-dimensional conformal irradiation to the primary tumor (55.8 Gy) and the lymphatics (50.4 Gy) was combined with 5-fluorouracil- or gemcitabine-based chemotherapy followed by additional chemotherapy with gemcitabine until progression or no further treatment. Decision for chemotherapy was taken at the discretion of the attending physician considering the patient's desire. Results: a total of 172 patients were addressed to the local tumor board. Patients with (neo)adjuvant treatment or metastatic disease were excluded (n = 90). 82 patients were treated with chemoradiation and had additional chemotherapy (n = 40) or no further treatment (n = 42). Characteristics of the two groups were equally distributed. Patients with chemotherapy had significantly longer overall survival as compared to patients without (13 months vs. 8 months; p < 0.0001; median survival = 10.7 months for all patients). Acute toxicity of maintenance chemotherapy was relatively mild. Conclusion: maintenance chemotherapy after chemoradiation for patients with locally advanced PaCa may significantly increase survival rates without severe side effects and is therefore recommended as standard treatment following chemoradiation.

    OBJECTIVE To investigate the effect of neoadjuvant chemotherapy in treatment of Stage II breast cancer.METHODS The data from 113 patients with breast cancer of the same pathologic type in Stage II, during the period of 1995 to 2001, were analyzed retrospectively. Among the patients, 47 were treated with neoadjuvant chemotherapy, and 66 received no adjuvant therapy before surgery (control group). After the patients of the neoadjuvant chemotherapy group had received 2 courses of chemotherapy with the CMF regimen, the surgical procedure was conducted.RESULTS Complete remission (CR) was attained in 9 of the 47 cases receiving neoadjuvant chemotherapy and partial remission (PR) was reached for 22 cases. The rate of breast-conserving surgery was enhanced from 22.73% to 46.81% (P<0.05) in the neoadjuvant treatment group. There was no difference in the 5-year overall survival (OS) and disease-free survival (DFS) rate between the two groups (P>0.05), but the 5-year OS and DFS of the cases with clinical tumor remission was higher compared to the control group (P<0.05).CONCLUSION Neoadjuvant chemotherapy can enhance the rate of breast conservation for Stage II breast cancer and may improve the prognosis of the cases with clinical remission.

    Background Neoadjuvant chemotherapy has been used as a primary treatment for locally advanced or inflammatory breast cancer, and recently extended to operable breast cancer. However, only a few studies have published data concerning the outcomes of patients with stages Ⅱ and Ⅲ breast cancer after neoadjuvant chemotherapy. Methods This study retrospectively investigated the clinical value of neoadjuvant chemotherapy for patients with stages Ⅱ and Ⅲ breast cancer. The patients in Group 1 (n=54) were treated with neoadjuvant chemotherapy, followed by definitive surgery and adjuvant therapy. The patients in Group 2 (n=43) initially received definitive surgery, followed by adjuvant chemotherapy and other therapies. The operability rates for breast conservation and dermatoplasty were observed in Group 1 after neoadjuvant chemotherapy. After follow-up, the recurrence and overall and disease-free survival rates of the two groups were analyzed.Results Neoadjuvant chemotherapy increased the operability rates for breast conservation from 17.1% to 40.0% in stage Ⅱ (P=0.034) and 0% to 12.6% in stage Ⅲ (P=0.016), and decreased the dermatoplasty rates from 17.1% to 2.8% in stage Ⅱ (P=0.046) and 28.1% to 8.1% in stage Ⅲ (P=0.026). After a median follow-up of 46.8 months, there were 11 deaths and 13 recurrences in Group 1, and 15 deaths and 19 recurrences in Group 2. The overall and disease-free survival rates of stage Ⅲ disease were significantly higher in Group 1 than in Group 2 (68.4% vs 31.2%, P=0.028, and 63.2% vs 25.0%, P=0.024, respectively). There were no significant differences in the overall and disease-free survival rates of stage Ⅱ disease for Group 1 compared with Group 2 (85.7% vs 85.2%, P=0.953, and 80.6% vs 74.1%, P=0.400, respectively).Conclusions Neoadjuvant chemotherapy resulted in increased operability for breast conservation and decreased dermatoplasty. Neoadjuvant chemotherapy exhibited better recurrence control, and overall and disease

  17. DNA damage in peripheral blood lymphocytes in patients during combined chemotherapy for breast cancer

    Combined chemotherapy is used for the treatment of a number of malignancies such as breast cancer. The target of these antineoplastic agents is nuclear DNA, although it is not restricted to malignant cells. The aim of the present study was to assess DNA damage in peripheral blood lymphocytes (PBLs) of breast cancer patients subjected to combined adjuvant chemotherapy (5-fluorouracil, epirubicin and cyclophosphamide, FEC), using a modified comet assay to detect DNA single-strand breaks (SSB) and double-strand breaks (DSB). Forty-one female patients with advanced breast cancer before and after chemotherapy and 60 healthy females participated in the study. Alkaline and neutral comet assays were performed in PBLs according to a standard protocol, and DNA tail moment was measured by a computer-based image analysis system. Breast cancer patients before treatment had higher increased background levels of SSB and DSB as compared to healthy women. During treatment, a significant increase in DNA damage was observed after the 2nd cycle, which persisted until the end of treatment. Eighty days after the end of treatment the percentage of PBLs with SSB and DSB remained elevated, but the magnitude of DNA damage (tail moment) returned to baseline levels. There was no correlation between PBL DNA damage and response to chemotherapy. DNA-SSB and DSB in PBLs are present in cancer patients before treatment and increase significantly after combined chemotherapy. No correlation with response to adjuvant chemotherapy was found. Biomonitoring DNA damage in PBLs of cancer patients could help prevent secondary effects and the potential risks of developing secondary cancers

  19. Adjuvant trastuzumab in the treatment of her-2-positive early breast cancer: a meta-analysis of published randomized trials

    Breast cancer is the most common cancer in women in the U.S. and Western Europe. Amplification of the her-2/neu gene occurs in approximately 25% of invasive ductal carcinomas of the breast. The first HER-2/neu-targeted approach to reach the clinic was trastuzumab, a humanized monoclonal antibody directed against the extracellular domain of the HER-2/neu protein. Trastuzumab therapy prolongs the survival of patients with metastático HER-2/neu-overexpressing breast cancer when combined with chemotherapy and has recently been demonstrated to lead to dramatic improvements in disease-free survival when used in the adjuvant therapy setting in combination with or following chemotherapy. Here, we performed a meta-analysis of completed clinical trials of adjuvant trastuzumab in the adjuvant setting. Survival, recurrence, brain metastases, cardiotoxicity and directions for future research are discussed. A meta-analysis of randomized controlled trials (RCT) was performed comparing adjuvant trastuzumab treatment for HER2-positive early breast cancer (EBC) to observation. The MEDLINE, EMBASE, CANCERLIT and Cochrane Library databases, and abstracts published in the annual proceedings were systematically searched for evidence. Relevant reports were reviewed by two reviewers independently and the references from these reports were searched for additional trials, using guidelines set by QUOROM statement criteria. Pooled results from that five randomized trials of adjuvant Trastuzumab showed a significant reduction of mortality (p < 0.00001), recurrence (p < 0.00001), metastases rates (p < 0.00001) and second tumors other than breast cancer (p = 0.007) as compared to no adjuvant Trastuzumab patients. There were more grade III or IV cardiac toxicity after trastuzumab (203/4555 = 4.5%) versus no trastuzumab (86/4562 = 1.8%). The likelihood of cardiac toxicity was 2.45-fold higher (95% CI 1.89 – 3.16) in trastuzumab arms, however that result was associated with heterogeneity. The

    A 42-year-old man was referred to our hospital for macrohematuria. Computer tomography and magnetic resonance imaging revealed right hydronephrosis and a retroperitoneal mass, located next to right side of the bladder. Cystoscopy showed a protruded lesion covered with normal mucosa at the right lateral wall. The patient underwent transurethral resection of the bladder tumor and biopsies of the bladder wall. Histological examination showed squamous cell carcinoma. Neoadjuvant chemotherapy using paclitaxel and carboplatin (TC) was performed. A total cystectomy, right nephroureterectomy and construction of the ileal conduit were performed after one course of systemic chemotherapy. Histological examination showed urothelial carcinoma with squamous cell differentiation. Unexpectedly, a small amount of CIS was detected only in the vicinity of the TUR scar. The patient received 2 cycles of TC chemotherapy as adjuvant chemotherapy. Unfortunately, 11 months later, local recurrence and liver metastasis were detected. He died 17 months after the surgery.

    OBJECTIVE The breast cancer lack of expression of estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER-2) is defined as the Triple-negative breast cancer (TNBC). Our purpose is to compare the response and long-term effect of the TNBC and non-TNBC patients receiving neo-adjuvant anthracycline-based chemotherapy, and to investigate the mechanisms of TNBC affecting the survivals. METHODS Data of long-term follow-up (median, 5.4 years) of 326 patients who received neo-adjuvant chemotherapy with anthracycline-based regimen, during a period from 2000 to 2003, were analyzed. Expressions of ER, PR, HER-2, P53, Ki-67 and E-cadherin were determined using immunohistochemical staining method. A multivariate Cox regression analysis was used to analyze independent prognostic factors affecting the relapse-free survival (RFS) and overall survival (OS) rates. Clinical effects of the neo-adjuvant anthracycline-based chemotherapeutic regimen and the RFS and OS rates were compared between the patients with TNBC and non-TNBC, and the correlations among the triple- negative phenotype (TNP), tumor grading and the expressions of P53, Ki-67 and E-cadherins were analyzed. RESULTS TNP, TNM staging, histological grades, clinical response of the neo-adjuvant chemotherapy and pathological complete remission (pCR) rate were the independent prognostic factors affecting the survival rates. Furthermore, 70 (21.5%) of the 326 patients suffered TNBC. Compared with the subjects in non- TNBC group, the patients with TNBC had a significantly higher pCR rate (P=0.046) and clinical response rate (P=0.037), but also decreased 5-year RFS (P=0.001) and OS (P=0.004) rates. The RFS and OS rates were not improved in the TNBC patients who achieved a clinical remission after the neo-adjuvant chemotherapy. The triple-negative phenotype was positively correlated with the level of P53, Ki-67 expression (P=0.007, P=0.028), but negatively correlated with level of

    OBJECTIVE To evaluate the 10-year curative effects of short-term intensive neoadjuvant chemotherapy for operable breast cancer. METHODS A total of 510 patients with stagell and operable stagelll breast cancer were divided into group A (preoperative neoadjuvant chemotherapy 251 cases) and group B (postoperative adjuvant chemotherapy 259 cases). The patients in group A received short-term and intensive neoadjuvant chemotherapy for 4 weeks followed by modified radical mastectomy two weeks after the chemotherapy. The postoperative adjuvant chemotherapy began within two weeks after surgery. The same chemotherapeutic regimen was used for both groups. RESULTS For stage Ⅲ in group A the 5-year overall survival rate (OS) and disease-free survival rate (DFS) were 59.2% and 54.9% respectively which were higher than those in group B (28.3% and 20.8% respectively, P<0.05). The 10-year OS and DFS were 78.1% and 73.5% respectively for stage Ⅱ in group A which were higher than those in group B (68.4% and 60.7%, P<0.05). The 10-year OS and DFS were 42.3% and 40.4% respectively forstage Ⅲ in group A which were higher than those in group B (20.4% and 18.4% respectively, P<0.05). CONCLUSION The results showed that intensive neoadjuvant chemotherapy can improve the 10-year survival for patients with stage Ⅱ and operablestage Ⅲ breast cancer.

    Purpose: Prolonged radiation therapy treatment time (RTT) is associated with worse survival in several tumor types. This study investigated whether delays during adjuvant radiation therapy impact overall survival (OS) in gastric cancer. Methods and Materials: The National Cancer Data Base was queried for patients with resected gastric cancer who received adjuvant radiation therapy with National Comprehensive Cancer Network–recommended doses (45 or 50.4 Gy) between 1998 and 2006. RTT was classified as standard (45 Gy: 33-36 days, 50.4 Gy: 38-41 days) or prolonged (45 Gy: >36 days, 50.4 Gy: >41 days). Cox proportional hazards models evaluated the association between the following factors and OS: RTT, interval from surgery to radiation therapy initiation, interval from surgery to radiation therapy completion, radiation therapy dose, demographic/pathologic and operative factors, and other elements of adjuvant multimodality therapy. Results: Of 1591 patients, RTT was delayed in 732 (46%). Factors associated with prolonged RTT were non-private health insurance (OR 1.3, P=.005) and treatment at non-academic facilities (OR 1.2, P=.045). Median OS and 5-year actuarial survival were significantly worse in patients with prolonged RTT compared with standard RTT (36 vs 51 months, P=.001; 39 vs 47%, P=.005); OS worsened with each cumulative week of delay (P<.0004). On multivariable analysis, prolonged RTT was associated with inferior OS (hazard ratio 1.2, P=.002); the intervals from surgery to radiation therapy initiation or completion were not. Prolonged RTT was particularly detrimental in patients with node positivity, inadequate nodal staging (<15 nodes examined), and those undergoing a cycle of chemotherapy before chemoradiation therapy. Conclusions: Delays during adjuvant radiation therapy appear to negatively impact survival in gastric cancer. Efforts to minimize cumulative interruptions to <7 days should be considered.

  7. Adjuvant Radiation Therapy Treatment Time Impacts Overall Survival in Gastric Cancer

    Purpose: Prolonged radiation therapy treatment time (RTT) is associated with worse survival in several tumor types. This study investigated whether delays during adjuvant radiation therapy impact overall survival (OS) in gastric cancer. Methods and Materials: The National Cancer Data Base was queried for patients with resected gastric cancer who received adjuvant radiation therapy with National Comprehensive Cancer Network–recommended doses (45 or 50.4 Gy) between 1998 and 2006. RTT was classified as standard (45 Gy: 33-36 days, 50.4 Gy: 38-41 days) or prolonged (45 Gy: >36 days, 50.4 Gy: >41 days). Cox proportional hazards models evaluated the association between the following factors and OS: RTT, interval from surgery to radiation therapy initiation, interval from surgery to radiation therapy completion, radiation therapy dose, demographic/pathologic and operative factors, and other elements of adjuvant multimodality therapy. Results: Of 1591 patients, RTT was delayed in 732 (46%). Factors associated with prolonged RTT were non-private health insurance (OR 1.3, P=.005) and treatment at non-academic facilities (OR 1.2, P=.045). Median OS and 5-year actuarial survival were significantly worse in patients with prolonged RTT compared with standard RTT (36 vs 51 months, P=.001; 39 vs 47%, P=.005); OS worsened with each cumulative week of delay (P<.0004). On multivariable analysis, prolonged RTT was associated with inferior OS (hazard ratio 1.2, P=.002); the intervals from surgery to radiation therapy initiation or completion were not. Prolonged RTT was particularly detrimental in patients with node positivity, inadequate nodal staging (<15 nodes examined), and those undergoing a cycle of chemotherapy before chemoradiation therapy.

    Purpose: The outcomes of adjuvant chemoradiation for locally advanced rectal cancer are nonuniform among patients with matching prognostic factors. We explored the role of molecular markers for predicting the outcome of adjuvant chemoradiation for rectal cancer patients. Methods and Materials: The study included 68 patients with stages II to III rectal adenocarcinoma who were treated with total mesorectal excision and adjuvant chemoradiation. Chemotherapy based on 5-fluorouracil and leucovorin was intravenously administered each month for 6-12 cycles. Radiation therapy consisted of 54 Gy delivered in 30 fractions. Immunostaining of surgical specimens for COX-2, EGFR, VEGF, thymidine synthase (TS), and Raf kinase inhibitor protein (RKIP) was performed. Results: The median follow-up was 65 months. Eight locoregional (11.8%) and 13 distant (19.1%) recurrences occurred. Five-year locoregional failure-free survival (LRFFS), distant metastasis-free survival (DMFS), disease-free survival (DFS), and overall survival (OS) rates for all patients were 83.9%, 78.7%, 66.7%, and 73.8%, respectively. LRFFS was not correlated with TNM stage, surgical margin, or any of the molecular markers. VEGF overexpression was significantly correlated with decreased DMFS (P=.045), while RKIP-positive results were correlated with increased DMFS (P=.025). In multivariate analyses, positive findings for COX-2 (COX-2+) and VEGF (VEGF+) and negative findings for RKIP (RKIP-) were independent prognostic factors for DMFS, DFS, and OS (P=.035, .014, and .007 for DMFS; .021, .010, and <.0001 for DFS; and .004, .012, and .001 for OS). The combination of both COX-2+ and VEGF+ (COX-2+/VEGF+) showed a strong correlation with decreased DFS (P=.007), and the combinations of RKIP+/COX-2- and RKIP+/VEGF- showed strong correlations with improved DFS compared with the rest of the patients (P=.001 and <.0001, respectively). Conclusions: Molecular markers can be valuable in predicting treatment outcome of adjuvant

  9. Chemoradiation as primary or adjuvant treatment for locally advanced carcinoma of the vulva

    Purpose: To determine the impact of primary or adjuvant chemotherapy and radiation (CRT) on the survival rates of patients with locally advanced vulvar carcinoma. Methods and Materials: Between 1973 and 1998, 54 patients with vulvar cancer were treated with radiation therapy, among which 20 received CRT, while 34 patients received radiation therapy (RT) alone. Of the 20 patients, 14 were treated for primary or recurrent disease (pCRT), and 6 after radical vulvectomy for high-risk disease (aCRT). Of the 34 patients, 12 were treated primarily (pRT) and 22 received adjuvant treatment (aRT). Chemotherapy consisted of 2 courses of 5-fluorouracil (5-FU) and mitomycin C administered during RT. Six patients received cisplatin in place of mitomycin C. In CRT groups, radiation was administered to the vulva, pelvic, and inguinal lymph nodes to a median dose of 45 Gy with additional 6-17 Gy to gross disease. In RT groups, the median dose to the microscopic diseases was 45 Gy. Nine patients received external beam boost and 16 patients received supplementary brachytherapy in the forms of 226Ra or 241Am plaques to sites of macroscopic disease. Results: Overall survival was superior in the patients treated with pCRT versus pRT with statistical significance (p 0.04). There was also a statistically significant improvement in disease-specific (p = 0.03) and relapse-free survival (p = 0.01) favoring pCRT. No statistically significant trends of improved survival rates favoring aCRT over aRT were observed. Conclusion: Concurrent radiation therapy and chemotherapy decreases local relapse rate, improves disease-specific and overall survival over RT alone as primary treatment for locally advanced vulvar cancer

  10. Evidence-based adjuvant therapy for gliomas: Current concepts and newer developments

    2009-01-01

    Full Text Available The incidence of gliomas is increasing worldwide, including India. Of the 18,820 new cases of primary central nervous system (CNS tumors diagnosed annually in the United States, gliomas account for over 60% with 30-40% of them being glioblastoma multiforme (GBM, 10% being anaplastic astrocytoma (AA, and 10% being low grade gliomas (LGGs. This is in contrast to one study from West Bengal, India, in which only 7.9% of the brain tumors were GBMs, while 46.8% were astrocytomas. Of all adult primary CNS tumors, GBM is the most common and the most malignant with about 7,000 to 8,000 new cases annually in the United States. Given poor outcomes, a number of treatment approaches have been investigated. Common to these approaches is the use of adjuvant radiation therapy, even as surgery alone, with or without chemotherapy, may be the mainstay for some lower grade and low-risk gliomas. Today, treatment typically involves external beam radiation, with concurrent and adjuvant chemotherapy for more aggressive histologies. Although gliomas are relatively uncommon, active research is ongoing. Results of landmark trials along with some of the recently published trials are presented. These trials and management strategies as well as evolving concepts are found by reviewing over 200 articles in the National Library Medical (NLM database, PubMed, more than 60 of which are refrenced. Specifically, the database is searched using the following keywords, with various combinations: glioma, low-grade, anaplastic, astrocytoma, oligodendroglioma, oligoastrocytoma, glioblastoma multiforme, chemotherapy, radiation, new concepts, phase III, MGMT, CDX-110 (Celldex, temozolomide, 1p/19q deletion, and bevacizumab.

  11. Impact of Adjuvant Therapy on Survival in Curatively Resected Gallbladder Carcinoma

    Asthana, Anupam Kumar

    2015-01-01

    Background Gallbladder carcinoma (GBC) has the propensity to fail at loco-regional (LR) and distant sites despite aggressive radical surgery. Adjuvant therapy in the form of radiotherapy (RT), systemic chemotherapy (CT) and chemoradiation (CRT) is the usual practice. Due to rarity of this disease, there is limited evidence to suggest the type of adjuvant treatment which should be offered to the patients. Aim The study was conducted to evaluate the impact of adjuvant treatment on curatively resected GBC patients. Settings and Design Histological proven patients of GBC registered between June, 2008 and July, 2014 were identified from our hospital database and retrospective analysis was done. Materials and Methods Patients of GBC who had curative resection followed by adjuvant treatment as RT alone, CT alone or CRT were included in the study. Statistical Analysis Adverse prognostic factors and the effect of adjuvant treatment on overall survival (OS) and disease free survival (DFS) were evaluated using Cox Regression Method and Kaplan Meier plot. Results We identified 33 patients of which 23 were Stage I or II disease (Early disease) and the remaining 10 were Stage III or IV disease (Advanced disease). All except one patient had adenocarcinoma. A total of 5 patients were treated with RT alone while 16 patients received CT alone. The remaining 12 patients were treated with CRT. Median follow-up period was 8.5 months. At analysis 4 were alive while the remaining 29 were dead due to disease. With regard to “Early disease” patients who had RT alone, CT alone and CRT, the median OS was 22.3, 10.3 and 15.2 months respectively (p = .440). Cohort of patients with “Advanced disease” who were treated with CT alone and CRT the median OS was 7.5 and 7.0 months respectively (p = .643). On multivariate analysis none of the prognostic factors had an adverse impact on survival. Conclusion The impact of adjuvant treatment in the form of RT, CT or CRT after curative resection

    DNA methylation variations in gene promoter regions are well documented tumor-specific alterations in human malignancies including colon cancer, which may influence tumor behavior and clinical outcome. As a subset of colon cancer patients does not benefit from adjuvant chemotherapy, predictive biomarkers are desirable. Here, we describe that DNA methylation levels at CpG loci of hyaluronoglucosaminidase 2 (HYLA2) could be used to identify stage II and III colon cancer patients who are most likely to benefit from 5-flourouracil (5-FU) chemotherapy with respect to overall survival and progression-free survival.

  15. Chromonychia Secondary to Chemotherapy

    Marien Lopes

    2013-06-01

    Full Text Available Chemotherapy drugs can affect the skin and its appendages. Several clinical presentations can be observed, depending on the affected structure. The most common dermatological side effect is chromonychia. The main causative agents are: (1 cyclophosphamide, which can provoke a diffuse, black pigmentation, longitudinal striae and dark grey pigmentation located proximally on the nails; (2 doxorubicin, which promotes dark brown bands alternating with white striae and dark brown pigmentation in transverse bands, and (3 hydroxyurea, which produces a distal, diffuse, dark brown pigmentation. In the majority of cases, the effects are reversible after the suspension of the causative agent for a few months. We report a patient who developed chromonychia while undergoing treatment with cyclophosphamide, vincristine, doxorubicin, dexamethasone, methotrexate and cytarabine for acute lymphocytic leukemia.

  16. Chemotherapy of osteoarticular tuberculosis

    Hazra Avijit

    2005-01-01

    Full Text Available Tuberculosis (TB of the bones and joints is rampant in India with the dorsolumbar spine as the most common site of osseous involvement. For diagnosis, clinical suspicion needs to be confirmed through appropriate laboratory and imaging investigations, and increasingly nowadays, nucleic acid amplification techniques. Chemotherapy remains the cornerstone of management complemented by rest, nutritional support and splinting, as necessary. Operative intervention is required if response to chemotherapy is unsatisfactory and for spinal stabilization. The drugs and regimens are fundamentally similar to those for pulmonary TB. However, there is lack of consensus on the appropriate duration of treatment. The prevailing practice of extending treatment till radiological evidence of healing is complete, may be unnecessary in view of recent reports that 6-9 months of therapy is sufficient for the majority of cases. Relapse rates are not drastically improved by extending treatment to 12 months or even longer, except perhaps in pediatric cases. However, prolonged treatment may be required if surgical debridement is indicated but cannot be done. Multidrug-resistant TB should be suspected if disease activity shows no signs of abating after 4-6 months of uninterrupted therapy. These cases are therapeutically challenging and will require second line or experimental antiTB drugs, supported by resistance testing where feasible. Coexistent HIV/AIDS may also necessitate prolonged treatment. Interactions between first line antiTB drugs and antiretroviral medication can complicate matters. Close monitoring is essential in all cases, with dechallenge and cautious reinstitution of drugs in the event of toxicity. While awaiting the arrival of long overdue new antiTB medication, existing drugs and regimens must be used in an informed manner with emphasis on patient compliance.

  17. Methotrexate Toxicity in Growing Long Bones of Young Rats: A Model for Studying Cancer Chemotherapy-Induced Bone Growth Defects in Children

    Chiaming Fan

    2011-01-01

    Full Text Available The advancement and intensive use of chemotherapy in treating childhood cancers has led to a growing population of young cancer survivors who face increased bone health risks. However, the underlying mechanisms for chemotherapy-induced skeletal defects remain largely unclear. Methotrexate (MTX, the most commonly used antimetabolite in paediatric cancer treatment, is known to cause bone growth defects in children undergoing chemotherapy. Animal studies not only have confirmed the clinical observations but also have increased our understanding of the mechanisms underlying chemotherapy-induced skeletal damage. These models revealed that high-dose MTX can cause growth plate dysfunction, damage osteoprogenitor cells, suppress bone formation, and increase bone resorption and marrow adipogenesis, resulting in overall bone loss. While recent rat studies have shown that antidote folinic acid can reduce MTX damage in the growth plate and bone, future studies should investigate potential adjuvant treatments to reduce chemotherapy-induced skeletal toxicities.

  18. Survival in women with ovarian cancer before and after the introduction of adjuvant paclitaxel; a 25-year, single institution review.

    Shireen, R

    2012-02-01

    Adjuvant chemotherapy regime for ovarian cancer patients remains to be a contentious issue. The aim of this study was to compare the overall and progression-free survival of women with ovarian cancer before and after introduction of paclitaxel in our unit in 1992. A sample of 112 women who received adjuvant therapy following surgery for ovarian cancer was collected, 68 (61%) received platinum+alkylating agent before 1992 and later 44 (39%) received platinum+paclitaxel. Five-year survival was same in both treatment groups when there was no macroscopic disease after surgery (78% versus 70%) and when residual disease was <2 cm (50% versus 40%). Survival was greater in women with residual disease >2 cm in the platinum+paclitaxel group (50% versus 24%), (p = 0.04). However, progression-free survival was similar in both groups irrespective of stage or residual volume of disease. Therefore consideration to selective use of paclitaxel could reduce patient morbidity and costs significantly.

  19. Adjuvant chemotherapy in the treatment of intra-oral squamous cell carcinoma

    Forty five patients with intra-oral squamous cell carcinoma were treated with bleomycin (150 mg) and external irradiation (50 Gy/5 weeks). The response to treatment was observed in 82.2 per cent patients. Another group of 47 patients was irradiated with radical doses of radiotherapy (65 Gy/6 weeks). The response rate was 68.1 per cent. In the former group twenty six patients (57.8 per cent) survived, free from recurrence at five years. The survival rate in the control group was 40.4 per cent (19 out of 47). The toxicity was slightly more pronounced in the patients treated by the combination regime. However, most of them were able to complete the treatment uninterrupted. The literature has been reviewed to evaluate the efficacy of various dosage and fractionation schedules of the bleomycin and radiation, combination. (author). 4 tabs., 12 refs

  20. Adjuvant chemotherapy for brain tumors delivered via a novel intra-cavity moldable polymer matrix.

    Cheryl V Rahman

    Full Text Available INTRODUCTION: Polymer-based delivery systems offer innovative intra-cavity administration of drugs, with the potential to better target micro-deposits of cancer cells in brain parenchyma beyond the resected cavity. Here we evaluate clinical utility, toxicity and sustained drug release capability of a novel formulation of poly(lactic-co-glycolic acid (PLGA/poly(ethylene glycol (PEG microparticles. METHODS: PLGA/PEG microparticle-based matrices were molded around an ex vivo brain pseudo-resection cavity and analyzed using magnetic resonance imaging and computerized tomography. In vitro toxicity of the polymer was assessed using tumor and endothelial cells and drug release from trichostatin A-, etoposide- and methotrexate-loaded matrices was determined. To verify activity of released agents, tumor cells were seeded onto drug-loaded matrices and viability assessed. RESULTS: PLGA/PEG matrices can be molded around a pseudo-resection cavity wall with no polymer-related artifact on clinical scans. The polymer withstands fractionated radiotherapy, with no disruption of microparticle structure. No toxicity was evident when tumor or endothelial cells were grown on control matrices in vitro. Trichostatin A, etoposide and methotrexate were released from the matrices over a 3-4 week period in vitro and etoposide released over 3 days in vivo, with released agents retaining cytotoxic capabilities. PLGA/PEG microparticle-based matrices molded around a resection cavity wall are distinguishable in clinical scanning modalities. Matrices are non-toxic in vitro suggesting good biocompatibility in vivo. Active trichostatin A, etoposide and methotrexate can be incorporated and released gradually from matrices, with radiotherapy unlikely to interfere with release. CONCLUSION: The PLGA/PEG delivery system offers an innovative intra-cavity approach to administer chemotherapeutics for improved local control of malignant brain tumors.

    2010-09-01

    Full Text Available Abstract Background The molecular characteristics associated with the response to treatment in glioblastomas (GBMs remain largely unknown. We performed a retrospective study to assess the genomic characteristics associated with the response of GBMs to either first-line chemotherapy or radiation therapy. The gene expression (n = 56 and genomic profiles (n = 67 of responders and non-responders to first-line chemotherapy or radiation therapy alone were compared on Affymetrix Plus 2 gene expression arrays and BAC CGH arrays. Results According to Verhaak et al.'s classification system, mesenchymal GBMs were more likely to respond to radiotherapy than to first-line chemotherapy, whereas classical GBMs were more likely to respond to first-line chemotherapy than to radiotherapy. In patients treated with radiation therapy alone, the response was associated with differential expression of microenvironment-associated genes; the expression of hypoxia-related genes was associated with short-term progression-free survival ( 10 months. Consistently, infiltration of the tumor by both CD3 and CD68 cells was significantly more frequent in responders to radiotherapy than in non-responders. In patients treated with first-line chemotherapy, the expression of stem-cell genes was associated with resistance to chemotherapy, and there was a significant association between response to treatment and p16 locus deletions. Consistently, in an independent data set of patients treated with either radiotherapy alone or with both radiotherapy and adjuvant chemotherapy, we found that patients with the p16 deletion benefited from adjuvant chemotherapy regardless of their MGMT promoter methylation status, whereas in patients without the p16 deletion, this benefit was only observed in patients with a methylated MGMT promoter. Conclusion Differential expression of microenvironment genes and p16 locus deletion are associated with responses to radiation therapy and to first

  5. New generation adjuvants--from empiricism to rational design.

    O'Hagan, Derek T; Fox, Christopher B

    2015-06-01

    Adjuvants are an essential component of modern vaccine development. Despite many decades of development, only a few types of adjuvants are currently included in vaccines approved for human use. In order to better understand the reasons that development of some adjuvants succeeded while many others failed, we discuss some of the common attributes of successful first generation adjuvants. Next, we evaluate current trends in the development of second generation adjuvants, including the potential advantages of rationally designed synthetic immune potentiators appropriately formulated. Finally, we discuss desirable attributes of next generation adjuvants. Throughout, we emphasize that the importance of formulation and analytical characterization in all aspects of vaccine adjuvant development is often underappreciated. We highlight the formulation factors that must be evaluated in order to optimize interactions between vaccine antigens, immune potentiators, and particulate formulations, and the resulting effects on safety, biological activity, manufacturability, and stability.

  6. Pancreatic Neuroendocrine Tumors With Involved Surgical Margins: Prognostic Factors and the Role of Adjuvant Radiotherapy

    Purpose: Pancreatic neuroendocrine tumors (pNET) are rare neoplasms associated with poor outcomes without resection, and involved surgical margins are associated with a worse prognosis. The role of adjuvant radiotherapy (RT) in these patients has not been characterized. Methods and Materials: We retrospectively evaluated 46 consecutive patients with positive or close (<1 mm) margins after pNET resection, treated from 1983 to 2010, 16 of whom received adjuvant RT. Median RT dose was 50.4 Gy in 1.8-Gy fractions; half the patients received concurrent chemotherapy with 5-fluorouracil or capecitabine. No patients received adjuvant chemotherapy. Cox multivariate analysis (MVA) was used to analyze factors associated with overall survival (OS). Results: Median age at diagnosis was 56 years, and 52% of patients were female. Median tumor size was 38 mm, 57% of patients were node-positive, and 11% had a resected solitary liver metastasis. Patients who received RT were more likely to have larger tumors (median, 54 mm vs. 30 mm, respectively, p = 0.002) and node positivity (81% vs. 33%, respectively, p = 0.002) than those not receiving RT. Median follow-up was 39 months. Actuarial 5-year OS was 62% (95% confidence interval [CI], 41%–77%). In the group that did not receive RT, 3 patients (10%) experienced local recurrence (LR) and 5 patients (18%) developed new distant metastases, while in the RT group, 1 patient (6%) experienced LR and 5 patients (38%) developed distant metastases. Of all recurrences, 29% were LR. On MVA, male gender (adjusted hazard ratio [AHR] = 3.81; 95% CI, 1.21–11.92; p = 0.02) and increasing tumor size (AHR = 1.02; 95% CI, 1.01–1.04; p = 0.007) were associated with decreased OS. Conclusions: Long-term survival is common among patients with involved-margin pNET. Despite significantly worse pathologic features among patients receiving adjuvant RT, rates of LR between groups were similar, suggesting that RT might aid local control, and merits further

  7. Treatment of Oral Cavity Squamous Cell Carcinoma With Adjuvant or Definitive Intensity-Modulated Radiation Therapy

    Purpose: The optimal management of oral cavity squamous cell carcinoma (OCSCC) typically involves surgical resection followed by adjuvant radiotherapy or chemoradiotherapy (CRT) in the setting of adverse pathologic features. Intensity-modulated radiation therapy (IMRT) is frequently used to treat oral cavity cancers, but published IMRT outcomes specific to this disease site are sparse. We report the Dana-Farber Cancer Institute experience with IMRT-based treatment for OCSCC. Methods and Materials: Retrospective study of all patients treated at Dana-Farber Cancer Institute for OCSCC with adjuvant or definitive IMRT between August 2004 and December 2009. The American Joint Committee on Cancer disease stage criteria distribution of this cohort included 5 patients (12%) with stage I; 10 patients (24%) with stage II (n = 10, 24%),; 14 patients (33%) with stage III (n = 14, 33%),; and 13 patients (31%) with stage IV. The primary endpoint was overall survival (OS); secondary endpoints were locoregional control (LRC) and acute and chronic toxicity. Results: Forty-two patients with OCSCC were included, 30 of whom were initially treated with surgical resection. Twenty-three (77%) of 30 surgical patients treated with adjuvant IMRT also received concurrent chemotherapy, and 9 of 12 (75%) patients treated definitively without surgery were treated with CRT or induction chemotherapy and CRT. With a median follow-up of 2.1 years (interquartile range, 1.1–3.1 years) for all patients, the 2-year actuarial rates of OS and LRC following adjuvant IMRT were 85% and 91%, respectively, and the comparable results for definitive IMRT were 63% and 64% for OS and LRC, respectively. Only 1 patient developed symptomatic osteoradionecrosis, and among patients without evidence of disease, 35% experienced grade 2 to 3 late dysphagia, with only 1 patient who was continuously gastrostomy-dependent. Conclusions: In this single-institution series, postoperative IMRT was associated with promising LRC

The American Joint Committee on Cancer disease stage criteria distribution of this cohort included 5 patients (12%) with stage I; 10 patients (24%) with stage II (n = 10, 24%),; 14 patients (33%) with stage III (n = 14, 33%),; and 13 patients (31%) with stage IV. The primary endpoint was overall survival (OS); secondary endpoints were locoregional control (LRC) and acute and chronic toxicity. Results: Forty-two patients with OCSCC were included, 30 of whom were initially treated with surgical resection. Twenty-three (77%) of 30 surgical patients treated with adjuvant IMRT also received concurrent chemotherapy, and 9 of 12 (75%) patients treated definitively without surgery were treated with CRT or induction chemotherapy and CRT. With a median follow-up of 2.1 years (interquartile range, 1.1-3.1 years) for all patients, the 2-year actuarial rates of OS and LRC following adjuvant IMRT were 85% and 91%, respectively, and the comparable results for definitive IMRT were 63% and 64% for OS and LRC, respectively. Only 1 patient developed symptomatic osteoradionecrosis, and among patients without evidence of disease, 35% experienced grade 2 to 3 late dysphagia, with only 1 patient who was continuously gastrostomy-dependent. Conclusions: In this single-institution series, postoperative IMRT was associated with promising LRC

    Purpose: Pancreatic neuroendocrine tumors (pNET) are rare neoplasms associated with poor outcomes without resection, and involved surgical margins are associated with a worse prognosis. The role of adjuvant radiotherapy (RT) in these patients has not been characterized. Methods and Materials: We retrospectively evaluated 46 consecutive patients with positive or close (<1 mm) margins after pNET resection, treated from 1983 to 2010, 16 of whom received adjuvant RT. Median RT dose was 50.4 Gy in 1.8-Gy fractions; half the patients received concurrent chemotherapy with 5-fluorouracil or capecitabine. No patients received adjuvant chemotherapy. Cox multivariate analysis (MVA) was used to analyze factors associated with overall survival (OS). Results: Median age at diagnosis was 56 years, and 52% of patients were female. Median tumor size was 38 mm, 57% of patients were node-positive, and 11% had a resected solitary liver metastasis. Patients who received RT were more likely to have larger tumors (median, 54 mm vs. 30 mm, respectively, p = 0.002) and node positivity (81% vs. 33%, respectively, p = 0.002) than those not receiving RT. Median follow-up was 39 months. Actuarial 5-year OS was 62% (95% confidence interval [CI], 41%-77%). In the group that did not receive RT, 3 patients (10%) experienced local recurrence (LR) and 5 patients (18%) developed new distant metastases, while in the RT group, 1 patient (6%) experienced LR and 5 patients (38%) developed distant metastases. Of all recurrences, 29% were LR. On MVA, male gender (adjusted hazard ratio [AHR] = 3.81; 95% CI, 1.21-11.92; p = 0.02) and increasing tumor size (AHR = 1.02; 95% CI, 1.01-1.04; p = 0.007) were associated with decreased OS. Conclusions: Long-term survival is common among patients with involved-margin pNET. Despite significantly worse pathologic features among patients receiving adjuvant RT, rates of LR between groups were similar, suggesting that RT might aid local control, and merits further

  10. Contribution to the study of markers in lungs carcinogenesis and analysis of factors predicting the benefit of chemotherapy

    A better definition of early bio markers in lung carcinogenesis should enhance the development of molecular means to perform screening, diagnostic, and chemo-prevention of patients at high risk of lung cancer. We studied epigenetic deregulation of multiple promoters (p16(INK4a), HOX A9, MAGE A 1 et MAGE B2) in sputum samples from smokers at high risk and from patients with non-small cell lung cancer (N.S.C.L.C.). This molecular test, based on easily accessible sample,s can be modulated according to the aims of the investigator (e.g. screening or confirmation of diagnosis). Secondly, we have studied two candidate proteins as predictive markers of the benefit of adjuvant chemotherapy in patients with resected lung cancer. The multivariate analysis shows that tumor expression of the catalytic sub-unit of telomerase is not able to predict survival in patients included in the lAL T study' of adjuvant chemotherapy. However, tumor expression of the DNA repair protein ERCC1 identifies a sub-group of patients (ERCC1 negative) whose chances of survival are increased by 35% by means of cisplatin-based adjuvant chemotherapy. Further, tumor ERCC1 expression has a positive prognostic value in the non-treated control group. The need for a deeper understanding in cancerology of the physiological role of t
