Outcomes of neoadjuvant chemotherapy and radical hysterectomy for locally advanced cervical cancer at Kigali University Teaching Hospital, Rwanda: a retrospective descriptive study. BMC Womens Health 2024; 24:204. [PMID: 38555423 PMCID: PMC10981286 DOI: 10.1186/s12905-024-03024-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Accepted: 03/14/2024] [Indexed: 04/02/2024] Open
Abstract
BACKGROUND Half of countries in Africa lack access to radiation (RT), which is essential for standard treatment of locally advanced cervical cancers. We evaluated outcomes for patients treated with neoadjuvant chemotherapy (NACT) followed by radical hysterectomy in settings where no RT is available. METHODS We performed a retrospective descriptive study of all patients with FIGO stage IB2-IIA2 and some exceptional stage IIB cases who received NACT and surgery at Kigali University Teaching Hospital in Rwanda. Patients were treated with NACT consisting of carboplatin and paclitaxel once every 3 weeks for 3-4 cycles before radical hysterectomy. We calculated recurrence rates and overall survival (OS) rate was determined by Kaplan-Meier estimates. RESULTS Between May 2016 and October 2018, 57 patients underwent NACT and 43 (75.4%) were candidates for radical hysterectomy after clinical response assessment. Among the 43 patients who received NACT and surgery, the median age was 56 years, 14% were HIV positive, and FIGO stage distribution was: IB2 (32.6%), IIA1 (7.0%), IIA2 (51.2%) and IIB (9.3%). Thirty-nine (96%) patients received 3 cycles and 4 (4%) received 4 cycles of NACT. Thirty-eight (88.4%) patients underwent radical hysterectomy as planned and 5 (11.6%) had surgery aborted due to grossly metastatic disease. Two patients were lost to follow up after surgery and excluded from survival analysis. For the remaining 41 patients with median follow-up time of 34.4 months, 32 (78%) were alive with no evidence of recurrence, and 8 (20%) were alive with recurrence. One patient died of an unrelated cancer. The 3-year OS rate for the 41 patients who underwent NACT and surgery was 80.8% with a recurrence rate of 20%. CONCLUSIONS Neoadjuvant chemotherapy with radical hysterectomy is a feasible treatment option for locally advanced cervical cancer in settings with limited access to RT. With an increase in gynecologic oncologists skilled at radical surgery, this approach may be a more widely available alternative treatment option in countries without radiation facilities.

Abstract
Cervical cancer continues to be a global threat affecting individuals in resource poor communities disproportionately. The treatment paradigm for this disease is ever evolving with recent innovations propelling oncologic outcomes to a new frontier offering survival benefits for patients struggling with locally advanced disease and metastatic/recurrent carcinoma. Immunologic checkpoint inhibitors and anti-body drug conjugates represent two novel drug classes that have demonstrable activity in this disease, particularly in the first-line and second-line treatment paradigm for recurrence. The tolerability of these novel medicines and associated durable responses underscore regulatory approval by the U.S. Food and Drug Administrations and their implementation in clinic.

Abstract
PURPOSE This multicenter trial by the European Organisation for Research and Treatment of Cancer Gynecological Cancer Group was motivated by conflicting evidence on the value of neoadjuvant chemotherapy before surgery compared with concomitant chemoradiotherapy (CCRT) in stage IB2-IIB cervical carcinoma. METHODS Between May 2002 and January 2014, 626 patients with International Federation of Gynecology and Obstetrics stage IB2-IIb were randomly assigned between neoadjuvant chemotherapy followed by surgery (NACT-S; n = 314) and standard CCRT (n = 312). The primary end point was 5-year overall survival (OS) rate. Secondary end points were progression-free survival, OS, toxicity, and health-related quality of life (HRQOL). RESULTS After a median follow-up of 8.7 years, 198 patients (31.6%) died. Age, stage, and cell type were balanced in both arms. Protocol treatment was completed in 223 of 314 (71%) patients in NACT-S and 257 of 312(82%) in CCRT arms. Main reasons for incomplete protocol treatment were toxicity (30 of 314; 9.6%) and progressive disease (21 of 314; 6.7%) in the NACT-S arm and toxicity (23 of 312; 7.4%) and patient refusal (13 of 312; 4.2%) in the CCRT arm. Additional radiotherapy after completed NACT-S was given to 107 patients (48%), and additional surgery to 20 patients (8%) after completed CCRT. Short-term adverse events (AEs) ≥grade 3 occurred more frequently with NACT-S (41% v 23%), and long-term AEs ≥grade 3 more often with CCRT (21% v 15%). The 5-year OS was not significantly different between NACT-S (72%; 95% CI, 66 to 77) and CCRT (76%; 95% CI, 70 to 80). CONCLUSION This trial failed to demonstrate superiority in favor of the NACT-S arm but resulted in acceptable morbidity and HRQOL in both arms.

Abstract
Background Cervical cancer is the fourth most common malignancy in women, which is threatening female reproductive tract health. Chemotherapy can be used for neoadjuvant therapy of locally advanced cervical cancer and postoperative adjuvant therapy for patients with high-risk factors, so as to reduce the focus, sensitize radiotherapy, and reduce recurrence. The current first-line treatment is paclitaxel combined with platinum. Many literature studies have found that As2O3 alone or in combination with platinum drugs have good efficacy in a variety of tumors both in vivo and in vitro. Moreover, our research group has verified that the efficacy of As2O3 combined with platinum drugs in the treatment of cervical cancer is not inferior to the traditional first-line regimen at the cellular and animal levels, and paclitaxel is more expensive than As2O3. Hence, we aim to evaluate the clinical efficacy and safety of neoadjuvant chemotherapy with As2O3 and carboplatin in locally advanced cervical cancer. Methods Sixty participants in the IB2, IIA2, and IIB stages of cervical cancer will be recruited in this study. After excluding patients who did not meet the criteria, they were randomly assigned to two groups in a 1:1 ratio. All patients underwent colposcopic biopsies to confirm the diagnosis and detailed clinical examinations. Eligible patients will receive either 2 cycles of paclitaxel and carboplatin or As2O3 and carboplatin every 3 weeks. Patients were assessed for clinical efficacy after the second cycle of chemotherapy. Patients who had disease stable or disease progression at these time points will receive concurrent chemotherapy and radiation directly, while responders will receive PiverRutledge grade III radical hysterectomy and bilateral pelvic lymphadenectomy. Both groups of patients undergoing radical hysterectomy were given adjuvant therapy as per protocol-defined criteria. The efficacy and toxicity of the two groups were evaluated according to WHO acute and subacute toxicity classification standards. Discussion This is the first single-center, prospective, two-arm design, open-label randomized control trial that will evaluate the clinical efficacy and safety of neoadjuvant chemotherapy with As2O3 and carboplatin in locally advanced cervical cancer.

Abstract
BackgroundCisplatin-based concurrent chemoradiation is the standard treatment for locally advanced cervical cancer. In view of the difficulties associated with implementation of standard radiation protocols in low- and middle-income countries and the associated toxicities of chemoradiation, neoadjuvant chemotherapy followed by surgery has been tried as an alternative treatment for locally advanced cervical cancer.MethodsA comprehensive review was undertaken of the existing literature, caveats and potential avenues of neoadjuvant chemotherapy followed by surgery compared with chemoradiation in locally advanced cervical cancer.ResultsRandomized studies conducted in the pre-chemoradiation era comparing neoadjuvant chemotherapy followed by surgery with definitive radiotherapy alone showed favorable outcomes with the chemo-surgical approach. However, contemporary studies evaluating the role of neoadjuvant chemotherapy followed by surgery have failed to establish this approach as the standard. About 25–30% of patients who undergo neoadjuvant chemotherapy remain inoperable and require definitive chemoradiation. A similar proportion of patients would require adjuvant (chemo)radiation after neoadjuvant chemotherapy followed by surgery, resulting in excessive morbidity. Evaluation of time trends across the past few decades reveals that the advancements in delivery of radiation (external beam and brachytherapy) have translated into improvement in outcomes for locally advanced cervical cancer, while a similar trend was not observed for surgery or chemotherapy.ConclusionNeoadjuvant chemotherapy followed by surgery cannot be considered a standard of care in patients with locally advanced cervical cancer. This approach needs further clinical research to generate robust high-quality evidence especially for the sub-sets that might potentially benefit in terms of survival, toxicity and quality of life, against the gold standard treatment of concomitant chemoradiation.

Dose-Intense Cisplatin-Based Neoadjuvant Chemotherapy Increases Survival in Advanced Cervical Cancer: An Up-to-Date Meta-Analysis. Cancers (Basel) 2022; 14:cancers14030842. [PMID: 35159111 PMCID: PMC8834199 DOI: 10.3390/cancers14030842] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/01/2021] [Revised: 01/31/2022] [Accepted: 02/01/2022] [Indexed: 02/04/2023] Open
Abstract
Simple Summary Although neoadjuvant chemotherapy has become standard care for many locally advanced cancer sites, the benefit of neoadjuvant chemotherapy remains unclear for the treatment of locally advanced cervical cancer. With this meta-analysis, we set out to demonstrate the benefit of using dose-intense cisplatin-based neoadjuvant chemotherapy in terms of overall survival and progression-free survival. Dose-intense cisplatin-based neoadjuvant chemotherapy followed by local therapy was significantly associated with a survival benefit in the treatment of locally advanced cervical carcinoma. Even though radiotherapy combined with weekly cisplatin-based chemotherapy remains standard of care for the treatment of locally advanced cervical cancer, our meta-analysis makes it possible to consider the use of dose-intense cisplatin-based neoadjuvant chemotherapy when local treatment is suboptimal and opens perspectives for designing new clinical trials in this setting. Abstract Purpose: We set out to demonstrate the benefit of using dose-intense cisplatin-based neoadjuvant chemotherapy in terms of overall survival and progression-free survival. Methods: We searched through MEDLINE and Cochrane Library databases up to May 2021 to identify randomized clinical trials comparing the benefit of using cisplatin-based neoadjuvant chemotherapy followed by local treatment with local treatment alone for the treatment of locally advanced cervical cancer. The PRISMA statement was applied. Results: Twenty-two randomized clinical trials were retrieved between 1991 and 2019, corresponding to 3632 women with FIGO stages IB2-IVA cervical cancer. More than 50% of the randomized clinical trials were assessed as having a low risk of bias. There was no benefit of neoadjuvant chemotherapy on overall survival, but there was significant heterogeneity across studies (I2 = 45%, p = 0.01). In contrast, dose-intense cisplatin at over 72.5 mg/m2/3 weeks was significantly associated with increased overall survival (RR = 0.87, p < 0.05) with no heterogeneity across the pooled studies (I2 = 36%, p = 0.11). The survival benefit was even greater when cisplatin was administered at a dose over 105 mg/m2/3 weeks (RR = 0.79, p < 0.05). Conclusion: Even though radiotherapy combined with weekly cisplatin-based chemotherapy remains standard of care for the treatment of locally advanced cervical cancer, our meta-analysis makes it possible to consider the use of dose-intense cisplatin-based neoadjuvant chemotherapy when local treatment is suboptimal and opens perspectives for designing new clinical trials in this setting. Neoadjuvant chemotherapy could be proposed when surgery is local treatment instead of standard chemoradiotherapy for the treatment of locally advanced cervical cancer.

Int J Gynecol Cancer 2021; 31:824-828. [PMID: 33858952 DOI: 10.1136/ijgc-2021-002432] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Revised: 03/26/2021] [Accepted: 03/31/2021] [Indexed: 11/04/2022] Open
Abstract
OBJECTIVE In this study we investigated response rates of bevacizumab in addition to weekly paclitaxel and carboplatin in neoadjuvant setting in cervical cancer stage IB-IIB. METHODS In this retrospective study we included patients with FIGO 2018 stage IB-IIB cervical cancer. Treatment consisted of 9 weeks' neoadjuvant paclitaxel and carboplatin (paclitaxel 60 mg/m2, carboplatin AUC 2.7; both weekly) and bevacizumab (15 mg/kg every 3 weeks). The radiologic response rate was analyzed using the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria. The definition of optimal pathological response was complete disappearance of tumor (complete response, pCR) or residual disease with less than 3 mm stromal invasion (pPR1). Suboptimal pathologic response (pPR2) was defined as persistent residual disease with more than 3 mm stromal invasion. RESULTS A total of 30 patients were included. Six patients had FIGO 2018 stage IB1-IB2 (20%), one had stage IB3 (3%), five had stage IIA (17%), and 18 had stage IIB (60%). After completing the neoadjuvant chemotherapy, all patients showed a RECIST response (seven (23%) complete response; 23 (77%) partial response). Six patients (20%) were judged to be still inoperable. After radical hysterectomy, optimal pathological response was observed in 11 patients (38%) (pCR in nine patients (29%) and pPR1 in two patients (8%)). Six patients (20%) received postoperative adjuvant chemoradiotherapy. Hematological toxicity was similar to neoadjuvant weekly paclitaxel and carboplatin, as we reported earlier. Grade IV proteinuria or hypertension was not observed and no administration of bevacizumab was delayed or dose-reduced. CONCLUSION Bevacizumab in addition to weekly paclitaxel and carboplatin showed a 100% radiological RECIST response and an optimal pathological response of 38%. Although bevacizumab has an established role in the treatment of recurrent cervical cancer in combination with paclitaxel and carboplatin, we did not observe a tendency toward superior effect on the pathological response rate of bevacizumab in the neoadjuvant chemotherapy setting.

Abstract
Background This study was to compare the efficacy and safety between neoadjuvant chemotherapy followed by radical surgery (NACT+RS) and radiotherapy only (RT) or concurrent chemoradiotherapy (CCRT) for treatment of patients with stage IB2, IIA, or IIB cervical cancer. Method The electronic databases of PubMed, Embase, and the Cochrane Library were searched to screen relevant studies from their inception to October 2018. Clinical data including overall survival (OS), disease-free survival (DFS), and adverse events were extracted. Egger's test was used to evaluate the publication bias, and sensitivity analysis was conducted to estimate the robustness of results. Results Finally, three randomized controlled trials (RCTs) and two case-control studies consisting of 1,275 patients with stage IB2, IIA, or IIB cervical cancer were included in the current study. Overall, pooled results showed no significant differences in OS ((hazard ratio (HR) = 0.603, 95%CI = 0.350 − 1.038) and DFS (HR = 0.678, 95%CI = 0.242 − 1.904) for patients treated with NACT+RS compared with RT only or CCRT, but the subgroup analysis showed that the OS and DFS were significantly longer in the NACT+RS groups than the RT or CCRT group (OS: HR = 0.431, 95%CI = 0.238 − 0.781, p = 0.006; DFS: HR = 0.300, 95%CI = 0.187 − 0.482, p < 0.001) for the population with median follow-up time of more than 60 months. For adverse events, the incidence of thrombocytopenia in the NACT+RS group was significantly higher than that in the RT only or CCRT group (relative risk (RR) = 3.240, 95% CI 1.575-6.662), while the incidence of diarrhea was significantly lower than that in the RT only or CCRT group (RR = 0.452, 95% CI =0.230-0.890). Conclusion These findings suggest that the short-term therapeutic effects of the two treatments may be possibly equal for patients with stage IB2-IIB cervical cancer, but the long-term effects for improving OS and DFS may be better using NACT+RS compared with the RT only or CCRT.

Abstract
Treatment options in locally advanced cervix cancer (LACC) have evolved around radiation therapy (RT) and/or chemotherapy (CT), hypoxic cell sensitizers, immunomodulators (Imm), and locoregional moderate hyperthermia (HT). A systematic review and network meta-analysis was conducted to synthesize the evidence for efficacy and safety in terms of long-term locoregional control (LRC), overall survival (OS), and grade ≥3 acute morbidity (AM) and late morbidity (LM). Five databases were searched, and 6285 articles (1974-2018) were screened per the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. Fifty-nine randomized trials in untreated LACC without surgical intervention were shortlisted. These used 13 different interventions: RT alone and/or neoadjuvant CT (NACT), adjuvant CT (ACT), concurrent chemoradiation therapy (CTRT) (weekly cisplatin [CDDP]/3-weekly CDDP/combination CT with CDDP/non-CDDP-based CT), hypoxic cell sensitizers, Imm, or HT. Odds ratios (ORs) using random effects network meta-analysis were estimated. Interventions for each endpoint were ranked according to their corresponding surface under cumulative ranking curve values. Of the 9894 patients evaluated, the total events reported for LRC, OS, AM, and LM were 5431 of 8197, 4482 of 7958, 1710 of 7183, and 441 of 6333, respectively. ORs and 95% credible intervals (CrIs) for the 2 best strategies were HT + RT versus CTRT + ACT (OR, 1.23; 95% CrI, 0.49-3.19) for LRC, CTRT (3-weekly CDDP) versus HTCTRT (OR, 1.14; 95% CrI, 0.35-3.65) for OS, RT + ACT versus RT (OR, 0.01; 95% CrI, 0.00-1.04) for AM, and NACT + RT + ACT versus RT + Imm (OR, 0.42; 95% CrI, 0.02-7.39) for LM. The 3 interventions with the highest cumulative surface under cumulative ranking curve values for all 4 endpoints were HTRT, HTCTRT, and CTRT (3-weekly CDDP). Articles with low risk of bias and those published during 2004 to 2018 also retained these interventions as the best. Two-step cluster analysis grouped these 3 modalities in a single distinctive cluster. HTRT, HTCTRT, and CTRT with 3-weekly CDDP were identified as therapeutic modalities with the best comprehensive impact on key clinical endpoints in LACC. This warrants a phase 3 randomized trial among these strategies for a head-to-head comparison and additional validation.

de la Torre M. Neoadjuvant chemotherapy in woman with early or locally advanced cervical cancer. Rep Pract Oncol Radiother 2018; 23:528-532. [PMID: 30534016 PMCID: PMC6277351 DOI: 10.1016/j.rpor.2018.09.005] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2018] [Revised: 08/23/2018] [Accepted: 09/06/2018] [Indexed: 10/28/2022] Open
Abstract
Cervical cancer is a major global health problem for women. Despite the screening and vaccines available today, it continues to be the fourth most common cancer in women worldwide with 85% of cases occurring in developing countries. Standard treatments for early or locally advanced cervical cancer are surgery (S) or concomitant chemo-radiotherapy (CT-RT). Neoadjuvant chemotherapy (NACT) prior to surgery or radiotherapy has been proposed and tested in clinical trials and has been included in clinical practice in some countries.In order to determine the true role of NACT either prior to S or RT in terms of achieving benefits in OS or DFS, randomized clinical trials and meta-analyses published from its beginnings to the present have been searched and analyzed in this study.The analysis of published clinical trials shows that NACT followed by S and NACT followed by RT have failed to demonstrate benefits in OS or DFS. Clinical trials comparing NACT followed by S versus exclusive RT have also been analyzed, where NACT followed by S could not show benefits for RT either. CONCLUSION Adding neoadjuvant chemotherapy to S or RT cannot be recommended outside the context of clinical trials.

Abstract
Purpose We compared the efficacy and toxicity of neoadjuvant chemotherapy followed by radical surgery versus standard cisplatin-based chemoradiation in patients with locally advanced squamous cervical cancer. Patients and Methods This was a single-center, phase III, randomized controlled trial ( ClinicalTrials.gov identifier: NCT00193739). Eligible patients were between 18 and 65 years old and had stage IB2, IIA, or IIB squamous cervical cancer. They were randomly assigned, after stratification by stage, to receive either three cycles of neoadjuvant chemotherapy using paclitaxel and carboplatin once every 3 weeks followed by radical hysterectomy or standard radiotherapy with concomitant cisplatin once every week for 5 weeks. Patients in the neoadjuvant group received postoperative adjuvant radiation or concomitant chemotherapy and radiotherapy, if indicated. The primary end point was disease-free survival (DFS), defined as survival without relapse or death related to cancer, and secondary end points included overall survival and toxicity. Results Between September 2003 and February 2015, 635 patients were randomly assigned, of whom 633 (316 patients in the neoadjuvant chemotherapy plus surgery group and 317 patients in the concomitant chemoradiation group) were included in the final analysis, with a median follow-up time of 58.5 months. The 5-year DFS in the neoadjuvant chemotherapy plus surgery group was 69.3% compared with 76.7% in the concomitant chemoradiation group (hazard ratio, 1.38; 95% CI, 1.02 to 1.87; P = .038), whereas the corresponding 5-year OS rates were 75.4% and 74.7%, respectively (hazard ratio, 1.025; 95% CI, 0.752 to 1.398; P = .87). The delayed toxicities at 24 months or later after treatment completion in the neoadjuvant chemotherapy plus surgery group versus the concomitant chemoradiation group were rectal (2.2% v 3.5%, respectively), bladder (1.6% v 3.5%, respectively), and vaginal (12.0% v 25.6%, respectively). Conclusion Cisplatin-based concomitant chemoradiation resulted in superior DFS compared with neoadjuvant chemotherapy followed by radical surgery in locally advanced cervical cancer.

Abstract
ObjectiveNeoadjuvant chemotherapy (NACT) followed by surgery in cervical cancer is widely studied with paclitaxel-ifosfamide-cisplatinum 3 weekly (TIP). Although the response rates with TIP are high, the toxicity is substantial. Therefore, this study evaluates dose-dense paclitaxel-carboplatin (TC) as an alternative.MethodsIn this prospective phase 2 study trial, we included 36 patients with International Federation of Gynecology and Obstetrics (FIGO) stage IB1 to IIB cervical cancer, who received 9 weeks’ NACT dose-dense TC (median weekly dose paclitaxel 60 mg/m2, carboplatinum area under the curve 2.7). Radiological response was evaluated by RECIST (Response Evaluation Criteria in Solid Tumors). Optimal pathologic response (OPT) was defined as complete disappearance of tumor (complete response [CR]) or residual disease with less than 3-mm stromal invasion (PR1). Suboptimal pathologic response consisted of persistent residual disease with more than 3-mm stromal invasion (PR2).ResultsNine patients had a FIGO stage IB1 (25%), 7 had stage IB2(19%), 3 had stage IIA (8%), and 17 had stage IIB disease (47%). Evaluation by magnetic resonance imaging after NACT showed 32 RECIST responses (89%) (CR in 11, PR in 21). Patients who were inoperable had insufficient reduction of the tumor to be operable (4 patients), progressive disease (1 patient), or stable disease (1 patient). Thirty patients were suitable for surgery after NACT. Pathology showed OPT in 50% (CR in 10, PR1 in 5). Thirteen patients had pathologic lymph nodes on radiological evaluation before start of chemotherapy. After chemotherapy, the lymph nodes were negative in 6 (47%) of these patients (pathologic complete remission). Postoperative chemoradiotherapy was administered in 11 patients (2 because of close resection margins, 5 because of metastatic lymph node after surgery, 2 because of close resection margins and metastatic lymph nodes after surgery, and 1 tumor >4 cm after NACT). Hematologic toxicity was acceptable with no febrile neutropenia and a low nonhematologic toxicity. The estimated 5-year overall survival was 70.8%.ConclusionsNeoadjuvant TC dose-dense in cervical carcinoma has a high response rate, comparable with TIP, and an acceptable toxicity.

Abstract
Despite availability of primary and secondary prevention measures, cervical cancer (CC) persists as one of the most common cancers among women around the world, and more than 70% of cases are diagnosed at advanced stages. Although significant progress has been made in the treatment of CC, around 15-61% of patients develop a recurrence in lymph nodes or distant sites within the first 2 years of completing treatment and the prognosis for these patients remains poor. During the last decades, in an attempt to improve the outcome in these patients, novel agents as combination therapy that target known dysfunctional molecular pathways have been developed with the most attention to the inhibitors of the angiogenesis process. One therapeutic target is the vascular endothelial growth factor, which has been shown to play a key role in tumor angiogenesis, not only for growth of new tissue but also in tumor proliferation. Bevacizumab is recognized as a potent antiangiogenic agent in ovarian cancer but has also demonstrated encouraging antitumor activity in recurrent CC. Moreover, other antiangiogenic agents were recently under study including: sunitinib, sorafenib, pazopanib, cediranib and nintedanib with interesting preliminary results. Moreover, over the last few years there has been increasing interest in cellular immunotherapy as a strategy to harness the immune system to fight tumors. This article focuses on recent discoveries about antiangiogenic agents and immunotherapies in the treatment of CC highlighting on future's view.

Patients treated with neoadjuvant chemotherapy + radical surgery + adjuvant chemotherapy in locally advanced cervical cancer: long-term outcomes, survival and prognostic factors in a single-center 10-year follow-up. Med Oncol 2016; 33:110. [PMID: 27577931 DOI: 10.1007/s12032-016-0830-0] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/08/2016] [Accepted: 08/25/2016] [Indexed: 10/21/2022]
Abstract
We report the long-term follow-up in patients with locally advanced cervical cancer treated with neoadjuvant chemotherapy (NACT) + radical surgery (RS) + adjuvant chemotherapy (ACT) analyzing prognostic factors which may more influence, in a long time, the survival outcome using univariate and multivariate analysis. In this study, we included all patients with diagnosis of locally advanced cervical cancer (IB2-IIB) treated with NACT + RS + ACT from June 2000 and February 2007 as previously described by Angioli et al. (Gynecol Oncol 127(2):290-6, 2012). The primary end-point of the study was overall survival (OS) in patients with node metastases and in those without positive lymph nodes at the end of 10-year follow-up in order to confirm the prognostic role of nodes involvement for a long period. Moreover, we analyzed the impact of other prognostic factors, such as histotype, tumor size, grading and parametrial invasion. Secondary end-point was evaluated in the subgroup of patients with positive nodes the following prognostic factors: number of positive lymph nodes and site of positive lymph nodes. In the subgroup of patients with positive nodes, the OS was 63 %, and in that with negative nodes, the OS was 75 %. On multivariate analysis, the number of nodal metastases, parametrial involvement, grading and the lesion diameter were noted to be significant factors in determining OS. Neither the histotype nor the lymph nodal site is related to survival. Results suggest that CT alone may be an alternative postoperative therapy for patients with cervical cancer.

Abstract
INTRODUCTION Cervical cancer is the second most common cause of female cancer death. In Morocco it is the second most common cancer, our department recruits more than 500 patients each year and proximally half of the cases are diagnosed at an advanced stage. PATIENTS AND METHODS Between January 2008 and December 2008, all patients with diagnosis of locally advanced cervical cancer referred to our department and treated with concurrent chemoradiotherapy were retrieved. We analyzed outcomes for this particular population; overall survival, local control, and toxicities, we also retrieved prognostic factors influencing outcomes for this population. RESULTS The overall survival rate for the cohort was 68 % at 2 years, and reached 47 % at 5 years. The overall LC rate was 71 % at 2 years and 58 % at 5 years. The most important prognostic factors for OS and LC were the pretreatment hemoglobin, the tumor size, total duration of treatment, and the use of brachytherapy. For OS, the presence of enlarged lymph nodes was also important. For LC, the number of chemotherapy's courses was important. Of the included patients, 20 % experienced late grade 3 or 4 toxicity. CONCLUSION The results of our study have shown that despite all the treatment strategies available, locally advanced cervical cancer is associated with bad outcomes. In this cohort, the most important prognostic factors were the pretreatment hemoglobin level and the tumor size.

Abstract
The aim of this study is to evaluate the efficacy and safety of the combination of carboplatin and paclitaxel as neoadjuvant chemotherapy (NACT) in patients affected by locally advanced cervical cancer. Between June 2007 and May 2012, all patients with a diagnosis of locally advanced cervical cancer (IB2–IIB) were eligible for this protocol. All patients have received 3 cycles of carboplatin (AUC6) and paclitaxel 175 mg/mq in neoadjuvant setting. The NACT-induced toxicity and the response to treatment were evaluated according to the World Health Organization (WHO) criteria. After NACT, all patients with complete or partial response were submitted to classical radical hysterectomy type III or C2, according to different classifications, and were submitted to four adjuvant cycles of platinum-based chemotherapy. The primary endpoints of the study were to evaluate the efficacy and feasibility of carboplatin regimen. Thirty-five patients with locally advanced cervical cancer were considered. A total of 23 patients completed 3 cycles of NACT. The overall clinical response rate after NACT was 78.3% including 43.5% (n = 10) with complete response, 34.8% (n = 8) with partial response, 17.4% (n = 4) with stable disease and 4.3% (n = 1) of those who suffered disease progression. The most common toxicity was haematologic, nausea/vomiting and neuropathy with grades 1 and 2 and occurred in 56.5, 56.5 and 17.4%, respectively. No renal toxicity was registered. Our results suggest that carboplatin is a well-tolerated drug with a response rate similar to standard cisplatin. Then, it represents, in neoadjuvant setting, a valid alternative in patients affected by locally advanced cervical cancer.

Abstract
Cervical cancer is the second most frequent female malignancy worldwide. Concurrent chemoradiotherapy represents the standard of care for patients with advanced stage cervical cancer, while radical surgery (RS) and radiotherapy is widely used for treating early stage cervical cancer. However, the poor control of micrometastasis, declining operability, the lack of radiotherapy departments and the high incidence of long-term complications due to radiotherapy have brought about the development of different therapeutic approaches such as neoadjuvant chemotherapy followed by RS. Unfortunately, treatment results are still unsatisfactory due to a high recurrence rate and several authors have studied the possibility to add an adjuvant treatment to primary therapy. We reviewed the literature concerning the role of adjuvant chemotherapy in advanced cervical cancer after neoadjuvant chemotherapy followed by RS and after chemoradiotherapy.

OBJECTIVES To evaluate the efficacy, in terms of safety, overall survival and progression free survival of neoadjuvant chemotherapy followed by radical surgery plus adjuvant chemotherapy in patients affected by locally advanced cervical cancer (stage IB2-IIB) with or without node metastases. METHODS Between June 2000 and February 2007, all patients with diagnosis of locally advanced cervical cancer referred to the Division of Gynecologic Oncology of the University Campus Bio-Medico of Rome were eligible for this protocol. All enrolled patients received 3 cycles of platinum-based chemotherapy every 3 weeks according to the scheme Cisplatin 100mg/mq and Paclitaxel 175 mg/mq. After neoadjuvant chemotherapy all patients with stable or progressive disease were excluded from the protocol, the others were submitted to classical radical hysterectomy, bilateral salpingo-oophorectomy and bilateral systematic pelvic lymphadenectomy and 4 cycles of adjuvant treatment with platinum based chemotherapy were executed. RESULTS Concerning intention to treat basis analysis, 5 year overall survival (OS) and disease-free survival (DFS) are 77% and 61%, respectively. The 5-year OS of patients with positive pelvic nodes and those with negative nodes metastases was respectively 60% and 87%. Concerning the according to protocol analysis, the 5-year OS and DFS are 81% and 70% respectively. The 5-year OS in patient with positive and negative lymph nodes is 75% and 88% respectively. CONCLUSIONS The adjuvant chemotherapy regimen after neoadjuvant chemotherapy and radical surgery represents a valid treatment for patients with locally advanced cervical cancer.

Abstract
OBJECTIVE To evaluate the toxicity and efficacy of irinotecan plus cisplatin neoadjuvant chemotherapy (NACT) for cervical cancer. METHODS A total of 120 cases with cervical cancer were divided into 2 groups and retrospectively reviewed: Sixty FIGO IB2-IIB patients in NACT group were treated with 2 cycles of irinotecan 60 mg/m(2) on days 1 and 8 plus cisplatin 60 mg/m(2) on day 1 followed by surgery. Sixty FIGO IB2-IIB patients in control group were treated directly with surgery. RESULTS The 60 patients in NACT group received a total of 120 cycles. Grades III and IV neutropenia and diarrhea were seen in 15.8% and 11.7%, respectively, of all chemotherapy cycles. Six (10.0%) patients achieved complete remission, 33 (55.0%) achieved partial remission, 21 (35.0%) remained stable, and none had disease progression. Postoperatively the deep cervical stromal invasion and positivity of surgical margins were significantly fewer in the NACT group. The pelvic lymph node metastasis rate of responders to NACT was significantly lower than that of non-responders (12.8% vs 38.1%). With a median follow-up of 29 and 30 months, the intra-pelvic recurrence rate of the NACT group was significantly lower than that of the control group (3/60 vs 11/60, p=0.023), the 2-year recurrence-free survival and the 2-year overall survival was 82.3% and 86.1% in the NACT group, and 86.3%, 87.9% in the control group with no significant difference. Multivariate analysis showed that response to NACT was the only factor associated with survival (p=0.036). CONCLUSION Irinotecan plus cisplatin NACT for cervical cancer has high efficacy and tolerable toxicity, and can significantly reduce the rates of deep cervical stromal invasion and positive surgical margins. Pelvic lymph node metastasis decreases significantly in responders compared with non-responders. The response to NACT can be considered as an independent prognostic factor.

Abstract
BACKGROUND We report the therapeutic potential, longterm survival, and toxicity of neoadjuvant intraarterial chemotherapy (NAIC) using an original four-lumen double-balloon (4L-DB) catheter followed by radical hysterectomy and/or radiotherapy in patients with locally advanced cervical cancer. METHODS Sixty patients with stage IIB-IVA cervical squamous cell cancer were treated with NAIC which included cisplatin (60-70 mg/m(2), day 1), mitomycin-C (10-20 mg/m(2), day 1), and pirarubicin hydrochloride (THP; 10-20 mg/m(2), day 1) for two courses every 21 days. RESULTS The median follow up among surviving patients was 93.7 months. Among 60 eligible patients, 22 had a complete response (CR; 36.7%) including 12 with a pathologic CR (20.0%). Thirty-six patients had a partial response (60.0%), and stable disease was observed in only 2 patients (3.3%). Moreover, we found that the platinum concentration in the cervix was correlated with the clinical response (P < 0.001). The 10-year progression-free survival (PFS) and 10-year survival were 90.9% and 90.9%, respectively, in patients with stage IIB disease and 66.0% and 70.7%, respectively, in patients with stage III disease. Leukopenia occurred in 86.7% of patients, but it was not very severe (grade 3, 4 in 13.3% of patients). CONCLUSION Our results with NAIC using the 4L-DB catheter in locally advanced cervical cancer demonstrate that a high platinum concentration has beneficial effects on primary lesions and improves long-term progression-free and overall survival.

Abstract
For almost a century abdominal radical hysterectomy has been the standard surgical treatment of early-stage macroscopic carcinoma of the uterine cervix. The excessive parametrial resection of the original procedures of Wertheim, Okabayashi, and Meigs has later been "tailored" to tumor extent. Systematic pelvic and eventually periaortic lymph node dissection is performed to identify and treat regional disease. Adjuvant (chemo)radiation therapy is liberally added to improve locoregional tumor control when histopathological risk factors are present. The therapeutic index of the current surgical treatment, particularly if combined with radiation, appears to be inferior to that of primary chemoradiation as an oncologically equivalent therapeutic alternative. Several avenues of new conceptual and technical developments have been used since the 1990s with the goal of improving the therapeutic index. These are: surgical staging, including sentinel node biopsy and nodal debulking; minimal access and recently robotic radical hysterectomy; fertility-preserving surgery; nerve-sparing radical hysterectomy; total mesometrial resection based on developmentally defined surgical anatomy; and supraradical hysterectomy. The superiority of these new developments over the standard treatment remains to be demonstrated by controlled prospective trials. Multimodality therapy including surgery for locally advanced disease represents another area of clinical research. Both neoadjuvant chemotherapy followed by radical surgery, with or without adjuvant radiation, and completion surgery after (chemo)radiation are feasible and have to be compared to primary chemoradiation as the new nonsurgical treatment standard. Surgical treatment of postirradiation persisting or recurrent cervical carcinoma has been traditionally limited to pelvic exenteration for central disease. Applying the principle of developmentally derived anatomical compartments increases R0 resectability. The laterally extended endopelvic resection allows even the extirpation of a subset of visceral pelvic side wall tumors with clear margins. Many questions regarding the indication for these "ultraradical" operations, the surgery of irradiated tissues, and the optimal reconstructive procedures are still open and demand multi-institutional controlled trials to be answered.

Abstract
More than two decades have passed since neoadjuvant chemotherapy has been introduced in the clinical practice. After several pilot studies, randomized trials and meta-analysis have confirmed the validity of this therapeutic strategy and in particular of neoadjuvant chemotherapy followed by radical surgery. Several open questions still remain unanswered and in particular no standard drug regiment is unanimously accepted. In this paper we describe how this treatment has evolved since its original introduction in the early eighties and describe possible drug regimens with their supporting evidence that can be adopted by physicians worldwide.

Abstract
OBJECTIVE A randomized phase III trial was conducted to determine if neoadjuvant chemotherapy (NACT) prior to radical hysterectomy and pelvic/para-aortic lymphadenectomy (RHPPL) could improve progression-free survival (PFS) and overall survival (OS), as well as operability, with acceptable levels of toxicity. Adjuvant radiation therapy was prescribed for specific surgical/pathological risk factors for both regimens. METHODS Eligible patients were required to have bulky FIGO Stage IB cervical cancer, tumor diameter > or =4 cm, adequate bone marrow, renal and hepatic function, and performance status < or =2. Prospective random allocation was to either NACT (vincristine-cisplatin chemotherapy every 10 days for 3 cycles) before exploratory laparotomy and planned RHPPL (NACT+RHPPL), or RHPPL only. RESULTS The study was closed prematurely, because of slow accrual, after 291 patients were enrolled, three were ineligible; thus 288 were eligible and randomly allocated to RHPPL (N=143) or NACT+RHPPL (N=145). There were no notable differences between regimens with regard to patient age, race, performance status, or tumor size. The median follow-up time is 62 months among living patients. The NACT+RHPPL group had very similar recurrence rates (relative risk: 0.998) and death rates (relative risk: 1.008) when compared to the RHPPL group. There were 79% that had surgery in the RHPPL group compared to 78% in the NACT RHPPL group. There were 52% who received post op RT in the RHPPL group compared to 45% in the NACT+RHPPL group (not statistically significant). CONCLUSION There is no evidence from this trial that NACT offered any additional objective benefit to patients undergoing RHPPL for suboptimal Stage IB cervical cancer.

Abstract
BACKGROUND Concomitant chemoradiotherapy represents the standard treatment for patients affected by locally advanced cervical cancer. Survival rates in patients affected by FIGO stage IVA disease remain poor. Some authors have suggested that neoadjuvant chemotherapy followed by radical surgery might be a valid alternative to standard treatment. The objective of this study was to analyze the feasibility and results obtained by neoadjuvant chemotherapy in patients affected by stage IVA disease. METHODS Eighteen patients affected by FIGO stage IVA cervical cancer were treated with 175 mg/m(2) paclitaxel and 75 mg/m(2) cisplatin every 21 days for three courses followed by radical surgery when feasible. RESULTS All patients were subjected to the three planned chemotherapy courses. Two patients achieved a complete clinical response, and 10 patients achieved a partial clinical response. Ten patients were subjected to anterior pelvic exenteration, whereas the remaining eight patients were treated with chemotherapy, radiotherapy, and concomitant chemoradiotherapy. The estimated 3-year and 5-year overall survival rates were 47.4% and 31.6%, respectively. Patients eligible for surgery benefited from significantly longer survival rates. CONCLUSIONS Neoadjuvant chemotherapy followed by radical surgery is feasible in approximately half of patients affected by FIGO stage IVA cervical cancer. Overall survival rates appear similar to those reported with concomitant chemoradiotherapy. Patients who are amenable to radical surgery after chemotherapy may benefit from long-term survival rates.

Abstract
BACKGROUND A large number of trials have assessed various chemotherapy regimens for the treatment of advanced cervical cancer, but there is uncertainty about the magnitude of survival benefits. METHODS We searched (last update January 2006) for trials in women with locally advanced or disseminated cervical cancer that compared neo-adjuvant or concurrent chemotherapy plus radiotherapy versus radiotherapy alone; or different chemotherapy regimens among themselves (with or without background radiotherapy in both arms). Sixty-five trials were identified with survival data on 11,180 women. Results for survival were combined with fixed and random effects models and between-study heterogeneity was estimated. Separate results were obtained for different regimens, cycle length, and type of chemotherapy (neo-adjuvant, concurrent, without radiotherapy). RESULTS Twenty two comparisons had survival data on 3837 women randomized to receive chemotherapy plus radiotherapy versus radiotherapy alone; the summary relative hazard for mortality was 0.95, 95% CI, 0.83-1.08. Modest between-study heterogeneity (I2=38%) seemed to be due to contradictory results in early trials; trials published in the last decade had a summary relative hazard 0.89 (95% CI, 0.78-1.02) and no between-study heterogeneity (I2=0%). Results were similar for neo-adjuvant chemotherapy and for concurrent chemo-radiotherapy. Cisplatin or cisplatin-based combinations had no significant benefit overall, but a potential benefit was seen with short-length cycles (14 days) and a marginally significant harm with longer-length cycles (summary relative hazards 0.80, 95% CI, 0.66-0.99 and 1.18, 95% CI, 1.02-1.38, respectively). The summary relative hazard was 1.02, (95% CI, 0.84-1.24) for trials using neo-adjuvant chemotherapy and 0.85 (95% CI, 0.73-1.00) for trials using concurrent chemotherapy. CONCLUSIONS Evidence on chemotherapy in women with advanced cervical cancer is not encouraging for major survival benefits. However, small benefits have been observed in some trials, especially with short-length cycles of cisplatin-based regimens and concurrent chemotherapy and radiotherapy.

Abstract
Cervical cancer is the seventh most frequent cancer worldwide but more than 80% of cases occur in developing countries. Till date, radiation therapy with external beam and brachytherapy remains as the core treatment for most stages of cervical cancer. However, radiation treatment protocols and equipment modelled on the best developed countries can be seldom applied directly to developing countries owing to financial constraints and lack of qualified personnel, thus, a substantial proportion of patients do not have access to even palliative radiation therapy. Treatment options when the standard therapy is either not available or difficult to reproduce in particular settings is highly desirable with the potential to save lives that otherwise could be lost by the lack of adequate treatment. These options of treatment ideally had to have show, 1) that these are not inferior to the "standard" in terms of either survival or quality of life; 2) that these can be delivered in settings were the "standard" is not available or if available its quality is poor; and 3) that the treatment option be accepted by the population to be treated. Based on these considerations, it is obvious that cervical cancer patients, particularly those who live in countries with limited resources and therefore may not have sufficient radiation therapy resources are in need of newer therapeutical options. There is now a considerable amount of information emanating from clinical studies where surgery has a major role in treating this disease. These forms of "radiation-sparing" treatments include total mesometrial resection that could make unnecessary the use of adjuvant radiation; neoadjuvant chemotherapy that could avoid the use of adjuvant radiation in around 85% of patients and preoperative chemoradiation that could make brachytherapy dispensable. The feasibility and therapeutical value of these potential forms of management need to be prospectively evaluated.

Abstract
OBJECTIVE Intraoperative frozen section examination of pelvic lymph nodes is frequently used in patients with cervical cancer, some of whom have received neoadjuvant chemotherapy (NACT). However, NACT can cause necrosis, fibrosis, or keratinization of tumor deposits in extirpated lymph nodes, and it is unclear whether intraoperative frozen section analysis of extirpated nodes is accurate after NACT. We analyzed the accuracy of frozen section examination of pelvic lymph nodes in patients after NACT for cervical cancer. METHODS We reviewed 134 patients with invasive cervical cancer who underwent surgery including systematic pelvic lymphadenectomy with intraoperative frozen section examination of pelvic lymph nodes. Results of frozen section examination were related to definitive histology and compared between patient groups of NACT and primary surgery. RESULTS A total of 1670 pelvic lymph nodes were evaluated intraoperatively by frozen section examination, and 6689 pelvic lymph nodes were analyzed by final histopathology. Overall frozen section analysis had nine false negative results among 53 patients with positive lymph nodes (false negative rate, 16.9%). After NACT, there were two false negative diagnoses in twelve patients with node metastases (false negative rate, 16.7%). No false positive cases were noted. The sensitivity and negative predictive value of frozen section examination were 83% and 82%, respectively, in patients after NACT, and 83% and 91% at primary surgery. CONCLUSION NACT does not appear to compromise the diagnostic accuracy of intraoperative frozen section examination of pelvic lymph nodes in patients with cervical cancer.

Abstract
Worldwide, cervical cancer is the second most common malignancy in women and a major cause of morbidity and mortality. Until recently, the greatest strides in reducing cervical cancer mortality have occurred with the advent and implementation of screening programs. Many important advances have also taken place in the diagnosis and treatment of cervical cancer. This review article will highlight diagnostic and staging considerations with an emphasis on newer imaging modalities and how they might augment approved FIGO clinical staging. Management alternatives for patients with early-stage disease, locally advanced (stage IIB-IVA) disease, and metastatic cervical cancer will be discussed. Whenever possible, these discussions will unfold through an overview of pertinent clinical trials and current controversies.

Abstract
Two major treatment modalities in cervical cancer include radiotherapy and surgery. In an attempt to improve the outcome, these modalities have been increasingly supplemented by chemotherapy. Chemotherapy can be combined with local therapies in various sequences. Of the two possible strategies using chemotherapy and radiotherapy (sequential or concomitant), the latter seems to be more effective. Platinum-based regimens applied concurrently with both definitive and post-operative radiation therapy were demonstrated to provide survival benefit in five of the six recently published randomised trials. The positive impact of chemotherapy added to radiotherapy has also been shown in a meta-analysis including 1894 patients in 19 randomised studies. This strategy, however, is accompanied by increased early toxicity. The benefit of chemotherapy applied prior to surgery remains debatable. The role of new cytotoxic and biological substances, as well as agents combating tumour hypoxia, warrants further clinical investigation.

Abstract
PURPOSE We evaluated the effects of intra-arterial infusion therapy by comparing the results obtained with a combination of intra-arterial anticancer drugs with and without transcatheter arterial embolization (TAE) in patients with cervical cancer. METHODS Between April 1999 and March 2003, intra-arterial therapy was administered to 45 patients (mean age 49 years) with cervical cancer. Of these, 18 had stage IIb , 4 had stage IIIa, 19 had stage IIIb, and 4 had stage IVb cancer; the histopathologic types were squamous cell carcinoma (n = 35), adenocarcinoma (n = 8), and adenosquamous carcinoma (n = 2). A total of 45 patients gave their informed consent and were randomized on a continuous basis into one of three groups according to the therapeutic protocols: group A consisted of 15 patients who received cisplatin, group B consisted of 17 patients who received cisplatin, mitomycin, doxorubicin hydrochloride, and 5-fluorouracil, and group C consisted of 13 patients who received cisplatin and TAE. Each protocol was administered twice with a 3 week interval between treatments. The efficacy of treatment was evaluated on the basis of the tumor reduction ratio (%) using MR imaging and the side effects were analyzed. RESULTS In groups A, B, and C, the tumor reduction ratio was 54%, 84%, and 86%, respectively; it was significantly greater in groups B and C than in group A (p < 0.01). The difference between groups B and C was not statistically significant. Although all group C patients developed severe pain after TAE, the pain was controlled with analgesics. Thrombocytopenia occurred in 6 of 17 (35%) group B patients. CONCLUSION Group B and C patients had better tumor reduction than those in group A. Fewer hematologic complications occurred in group C patients compared with group B.

Abstract
Tumor size seems to be a determinant in the prognosis of early cervical cancer. Patients with tumor greater than 4 cm (bulky) in diameter have worse outcome. The purpose of this study was to compare the efficacy of preoperative combined chemoradiation and neoadjuvant chemotherapy (NAIC) programs followed by radical hysterectomy in stage IB-IIB bulky cervical cancer. From September 1999 to April 2002, 60 patients with stage IB-IIB bulky cervical cancer were treated with preoperative external-beam radiotherapy to 45 Gy plus weekly cisplatin 50 mg/m2 or preoperative NAIC by cisplatin 50 mg/m2 and vincristin 1 mg/m2 every 7-10 days, for three courses. Surgery was performed 4-6 weeks after the completion of the preoperative treatment. There were no significant difference between age, stage, tumor size, and histopathologic type in two groups (P > 0.05). Toxicity associated with two treatment methods was usually mild. In chemoradiation group, two patients developed vesicovaginal fistula, and four patients developed long-term hydronephrosis that needed urethral stenting. Before surgery, complete and partial clinical response had no significant difference between two groups (P > 0.05). After surgery, lymph node and parametrial involvement had no significant difference between two groups (P > 0.05). In NAIC group, more patients had significantly residual tumor (P = 0.012), but residual tumor size had no significant difference between two groups (P > 0.05). Pathologic complete response was significantly higher in chemoradiation group (P = 0.004). According to the result of this study, it seems that NAIC and chemoradiation had similar effects in survival prognostic factors.

Abstract
Platinum compounds have long played a role in the treatment of gynecologic cancers. Single-agent cisplatin and carboplatin have shown activity in endometrial cancer, and more recent studies have begun to investigate a variety of new platinum-based combinations. In cervical cancer, chemotherapy is used primarily to treat advanced or recurrent disease. Agents with proven single-agent activity in this setting include cisplatin, ifosfamide, and doxorubicin, and a number of cisplatin-based combination therapies are under clinical investigation. A variety of cisplatin-based combinations have also been used in ovarian cancer chemotherapy, with more recent studies investigating the substitution of carboplatin or oxaliplatin for cisplatin and the addition of paclitaxel. This review will examine recent clinical data on the use of platinum-based chemotherapies for the treatment of these gynecologic cancers.

Abstract
BACKGROUND Radiation therapy with concomitant chemotherapy is the standard treatment for locally advanced cervical cancer. In Mexico, most patients are still treated with radiation therapy alone. The aim of this work was to demonstrate that results obtained with combined treatments in the Mexican population are similar to those reported in the literature. METHODS Survival was analyzed in three sequential phase II studies of combined treatment: neoadjuvant chemotherapy followed by surgery (NEOCT+Sx) -February to July 1999; concomitant chemoradiotherapy (CT/RT) -August to December 1999; and neoadjuvant chemotherapy followed by surgery plus adjuvant chemoradiotherapy (NEOCT+Sx+CT/RT) -December 2000 to June 2001. These results were compared with a historical control group treated with radiation therapy alone between September and December 1998. The Kaplan-Meier product-limit method, log-rank test and Cox proportional hazards model were used for analysis. RESULTS Results showed that the three combined modalities significantly reduced the risk of death. Treatment with NEOCT+Sx reduced the risk to 0.452 (95% CI 0.246-0.830), p=0.010. The risk reduction with CT/RT was 0.408 (95% CI 0.218-0.762), p=0.005, and for the group of patients receiving NEOCT+Sx+CT/RT risk was reduced to 0.365 (95% CI 0.169-0.787), p=0.010. The corresponding absolute survival benefit was 14% for patients in stages IB2-IIA, 24% for IIB, and 21% for stage IIIB. CONCLUSIONS Within the limitations of a non-randomized study, our results are in agreement with those obtained from published randomized phase III trials which state that radiation therapy alone is a suboptimal treatment for locally advanced cervical cancer; hence, patients should receive cisplatin-based chemoradiotherapy as a standard treatment.

Abstract
PURPOSE OF REVIEW Although there is effective screening for cervical cancer, it continues to be a healthcare problem in developing countries. To increase survival rates, different strategies with neoadjuvant chemotherapy have been developed. Nearly all trials that analysed neoadjuvant chemotherapy plus surgery demonstrated an improved outcome, but most phase III trials that compared neoadjuvant chemotherapy plus radiotherapy with radiotherapy alone have failed to show further benefit. Recent data on neoadjuvant chemotherapy could change that assumption, so revision is needed. RECENT FINDINGS A meta-analysis by the Medical Research Council (UK) based on individual patient data (2074 patients, median follow-up 5.7 years) showed that there was no benefit of survival in patients treated with radiotherapy. Some interesting results were obtained when the trials were grouped together according to cycle length and dose intensity. Trials that gave more intensive chemotherapy in terms of a shorter cycle or a higher dose intensity tended to show an advantage for neoadjuvant chemotherapy. When analysing neoadjuvant chemotherapy followed by surgery, data from meta-analysis showed a reduction in the risk of death of 35% and an absolute gain of 14% in the 5-year survival. The reasons for this could be that short cycle length chemotherapy was used in this subgroup or the surgery may have removed radioresistant cell clones. SUMMARY Neoadjuvant chemotherapy may play a role in the treatment of women with cervical cancer. In future, it may be reasonable to compare it with concomitant chemoradiotherapy in terms of efficacy and toxicity.

Abstract
Cervical cancer is among the major health problems world-wide although advances in screening programs. Surgery and radiotherapy are the treatment modalities of choice for early and locally advanced cervical cancer. However, the role of chemotherapy in this setting has been better investigated in the latest years. To improve loco-regional control in locally advanced disease, authors have tested both neo-adjuvant chemotherapy and concurrent chemoradiotherapy. From 1999 NCI clinical announcement, concurrent cisplatin-based chemoradiation is considered the treatment of choice for cervical cancer patients requiring radiation therapy. Neo-adjuvant chemotherapy is reaching encouraging results in IB bulky-IIA cervical cancer, but further investigation are ongoing in locally advanced cervical setting. The optimal treatment for patients with metastatic or recurrent cervical cancer is still undefined and chemotherapy is used with palliation intent. Cisplatin remains the most active cytotoxic agents, although combinations of cisplatin with paclitaxel, topotecan, vinorelbine, have shown encouraging results in phase II and in early phase III studies. This paper reviews the role of chemotherapy in the management of patients with locally advanced, metastatic and recurrent cervical cancer. Studies discussed in this paper were selected trough a search in the med-line database performed in October 2003.

Abstract
Despite the enrollment of more than 3000 women in randomised trials, the benefits and risks of neoadjuvant chemotherapy in the treatment of locally advanced cervical cancer remain uncertain. We carried out a systematic review and meta-analysis of individual patient data to assess the effect of neoadjuvant chemotherapy in two comparisons. In the first comparison, of neoadjuvant chemotherapy followed by radical radiotherapy compared with the same radiotherapy alone, we obtained data from 18 trials and 2074 patients. When all trials were considered together, a high level of statistical heterogeneity suggested that the results could not be combined indiscriminately. A substantial amount of heterogeneity was explained by separate analyses of groups of trials. Trials using chemotherapy cycle lengths of 14 days and shorter (Hazard Ratio (HR))=0.83, 95% Confidence Interval (CI)=0.69-1.00, P=0.046) or cisplatin dose intensities greater than or equal to 25 mg/m2 per week (HR=0.91, 95% CI=0.78-1.05, P=0.20) tended to show an advantage for neoadjuvant chemotherapy on survival. In contrast, trials using cycle lengths longer than 14 days (HR=1.25, 95% CI=1.07-1.46, P=0.005) or cisplatin dose intensities lower than 25mg/m2 per week (HR=1.35, 95% CI=1.11-1.14, P=0.002) tended to show a detrimental effect of neoadjuvant chemotherapy on survival. In the second comparison, of neoadjuvant chemotherapy followed by surgery compared with radical radiotherapy alone, data from 5 trials and 872 patients were obtained. The combined results from all trials (HR=0.65, 95% CI=0.53-0.80, P=0.0004) indicated a highly significant reduction in the risk of death with neoadjuvant chemotherapy, but there were some differences between the trials in their design and results. Despite some unexplained heterogeneity, the timing and dose intensity of cisplatin-based neoadjuvant chemotherapy appears to have an important impact on whether or not it benefits women with locally advanced cervical cancer and warrants further exploration.

Abstract
BACKGROUND Despite the enrollment of more than 3000 women in randomised trials, the benefits and risks of neoadjuvant chemotherapy in the treatment of locally advanced cervical cancer remained uncertain. OBJECTIVES This systematic review and individual patient data (IPD) meta-analysis aimed to assess the effect of neoadjuvant chemotherapy in two comparisons: (1) neoadjuvant chemotherapy followed by radical radiotherapy compared to the same radiotherapy alone; and (2) neoadjuvant chemotherapy followed by surgery compared to radical radiotherapy alone. SEARCH STRATEGY Medline and CancerLit searches were supplemented with information from trial registers and by hand searching relevant meeting proceedings and by discussion with relevant trialists and organisations. These searches have been updated regularly until December 2002. SELECTION CRITERIA To be included, trials had to be properly randomised and had to include patients with locally advanced cervical cancer who had received neoadjuvant cytotoxic chemotherapy before radiotherapy or surgery or both treatments. Concurrent chemoradiotherapy trials were not included. The comparisons had to be unconfounded by use of additional agents or interventions. Patient enrollment should have started after 1 January 1975 and be completed by September 2000. DATA COLLECTION AND ANALYSIS We collected, validated and re-analysed updated trial data on all randomised patients from all relevant trials. Any queries were resolved and the final database entries verified by the responsible trial investigator, data manager or statistician. Two separate sets of analyses (by intention-to-treat) were carried out according to the treatment comparisons (1 and 2) already described. For all outcomes, we obtained overall pooled hazard ratios using the fixed effect model. To explore the potential impact of trial design, we pre-planned analyses that grouped trials by important aspects of their design that might influence the treatment effect. To investigate the effects of neoadjuvant chemotherapy within pre-specified subgroups of patients stratified logrank analyses were done on the primary endpoint of survival. MAIN RESULTS In the first comparison, we obtained data from 18 trials and 2074 patients. When all trials were considered together, a high level of statistical heterogeneity suggested that the results could not be combined indiscriminately. A substantial amount of heterogeneity was explained by separate analyses of groups of trials. Trials using chemotherapy cycle lengths shorter than 14 days (HR = 0.83, 95% CI = 0.69 to 1.00, p = 0.046) or cisplatin dose intensities greater than 25 mg/m2 per week (HR = 0.91, 95% CI = 0.78 to 1.05, p = 0.20) tended to show an advantage for neoadjuvant chemotherapy on survival. In contrast, trials using cycle lengths longer than 14 days (HR = 1.25, 95% CI = 1.07 to 1.46, p = 0.005) or cisplatin dose intensities lower than 25 mg/m2 per week (HR = 1.35, 95% CI = 1.11 to 1.14, p = 0.002) tended to show a detrimental effect of neoadjuvant chemotherapy on survival. In the second comparison, data from 5 trials and 872 patients were obtained.

REVIEWERS' CONCLUSIONS Despite some unexplained heterogeneity, the timing and dose intensity of cisplatin-based neoadjuvant chemotherapy appears to have an important impact on whether or not it benefits women with locally advanced cervical cancer and warrants further exploration.

Abstract
Anemia has long been reported to adversely affect the efficacy of radiation treatment in cervical cancer. On the basis of these findings, many radiation oncologists routinely use blood transfusions with the intent to maintain hemoglobin above specified levels during radiation therapy. However, allogeneic blood transfusions have been previously linked with biological and clinical phenomena correlated with immune suppression. In this study we have analyzed the effects of blood transfusion on the outcome of 130 patients with stage-IIB and -III cervical carcinomas treated with external radiation and intracavitary brachytherapy with or without concomitant platinum administration at the University of Arkansas for Medical Sciences between 1990 and 1999. With the exception of hemoglobin and hematocrit levels at the onset of treatment between the transfused and untransfused groups (p < 0.001), the distribution of age, histology, total radiation dose and duration of treatment were not significantly different between the 2 groups of stage-IIB and -III patients. Among the 45 stage-IIB patients who received blood during radiation treatment, there were 31 deaths (68.8%), compared with 14 (31.8%) among the 44 patients who did not receive blood (p > 0.05). Among the 30 stage-III patients who received blood during radiation treatment, there were 27 deaths (90%), compared with 6 (54%) among the 11 patients who did not receive blood (p > 0.11). In multivariate analysis of survival, there was a significant difference due to transfusion with a risk ratio (RR) of 2.6 (95% CI 1.6, 4.2; p < 0.001) after adjusting for no chemotherapy (RR = 2.2, 95% CI 1.4, 3.5; p < 0.001), considering all patients collectively, stage-IIB patients only (RR = 1.9, 95% CI 1.1, 3.3; p < 0.01), and stage-III patients only (RR = 3.2, 95% CI 1.2, 8.7; p < 0.02). These results suggest that routine blood transfusion of anemic cervical cancer patients does not improve outcome and may represent an independent variable predictive of diminished survival during primary radiation treatment for cervical cancer. Prospective randomized studies are strongly warranted to confirm this hypothesis.

Abstract
Radiation was until recently the key and only modality for the routine treatment of locally advanced cervical carcinoma. However after years of studying multi-modality treatments as an alternative to radiation alone in randomized phase III trials, the standard treatment has changed to chemo-radiation based on cisplatin. Three recent meta-analyses have confirmed that cisplatin-based chemo-radiation adds an absolute 12% benefit in five-year survival over radiation therapy alone. Neoadjuvant chemotherapy followed by radiation has not been of proven benefit, but when neoadjuvant chemotherapy is followed by surgery, an absolute increase of 15% in five-year survival over radiation alone is seen. This benefit in survival is comparable to that obtained with the current chemo-radiation schedules based on cisplatin. Despite these encouraging results there remains room for improvement as the five-year survival of patients treated with chemo-radiation ranges from nearly 80% in bulky IB tumours to only 25% in stage IVA disease. Other therapeutic approaches need to be fully evaluated including the use of chemo-radiation after neoadjuvant chemotherapy; the use of new drug combinations and the multi-modality combination of neoadjuvant chemotherapy followed by radical surgery plus adjuvant chemo-radiation. Likewise, the addition of radiosensitizers to cisplatin, preoperative chemo-radiation and/or adjuvant chemotherapy may eventually improve the currents results of cisplatin-based chemo-radiation. Nevertheless, it is hard to foresee a dramatic increase in cure rate, even with the most optimal combination of cytotoxic drugs, surgery and radiation, and thus the testing of molecular targeted therapies against cervical cancer is a logical step to follow.
