Abstract
Introduction Squamous cell carcinoma antigen (SCC Ag) is a sub-fraction of the tumor antigen TA-4, first isolated by Kato and Torigoe, the most commonly used tumor marker in cervical cancer. It can be used as a serum marker to detect residual disease, early local recurrence, or distant metastasis in locally advanced cervical cancer even before the clinical symptoms of recurrence or metastasis. Methods and Materials Between January 2018 and August 2018, 30 patients with squamous cell carcinoma cervix (FIGO) stages IB2-IVA, who received concurrent chemoradiation, followed by brachytherapy, were included in the study. Serum SCC Ag levels were collected at four time points during the course of the treatment, and their correlation with tumor and treatment factors were analyzed. Results As the FIGO stage increases, mean pre-treatment SCC Ag also increases. Node-positive patients had higher pre-treatment SCC Ag as compared to those who were negative (P = 0.05). There was a statistically significant decreasing trend in the mean SCC Ag at the end of EBRT (P = 0.015). After completion of treatment, 78% had a complete response, 8% had a partial response, and 14% had progressive disease with statistically significant elevation of SCC Ag at 6 weeks of follow-up (P = 0.01). Patients who progressed or had the residual disease at follow-up were found to have high pre-treatment SCC Ag values. Conclusion SCC Ag can be potentially used as a reference indicator of biological behavior of cervical cancer, to monitor the treatment response, and as a prognostic marker, especially in those with node-positive disease.

Zhang GY, Zhang R, Bai P, Li SM, Zhang YY, Chen YR, Huang MN, Wu LY. Concurrent definitive chemoradiation incorporating intensity-modulated radiotherapy followed by adjuvant chemotherapy in high risk locally advanced cervical squamous cancer: a phase II study. BMC Cancer 2022; 22:1331. [PMID: 36539745 PMCID: PMC9764592 DOI: 10.1186/s12885-022-10406-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/14/2021] [Accepted: 12/06/2022] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Although the prognosis of locally advanced cervical cancer has improved dramatically, survival for those with stage IIIB-IVA disease or lymph nodes metastasis remains poor. It is believed that the incorporation of intensity-modulated radiotherapy into the treatment of cervical cancer might yield an improved loco-regional control, whereas more cycles of more potent chemotherapy after the completion of concurrent chemotherapy was associated with a diminished distant metastasis. We therefore initiated a non-randomized prospective phaseII study to evaluate the feasibility of incorporating both these two treatment modality into the treatment of high risk locally advanced cervical cancer. OBJECTIVES To determine whether the incorporation of intensity-modulated radiotherapy and the addition of adjuvant paclitaxel plus cisplatin regimen into the treatment policy for patients with high risk locally advanced cervical cancer might improve their oncologic outcomes. STUDY DESIGN Patients were enrolled if they had biopsy proven stage IIIA-IVA squamous cervical cancer or stage IIB disease with metastatic regional nodes. Intensity-modulated radiotherapy was delivered with dynamic multi-leaf collimators using 6MV photon beams. Prescription for PTV ranged from 45.0 ~ 50.0 Gy at 1.8 Gy ~ 2.0 Gy/fraction in 25 fractions. Enlarged nodes were contoured separately and PTV-nodes were boosted simultaneously to a total dose of 50.0-65 Gy at 2.0- 2.6 Gy/fraction in 25 fractions. A total dose of 28 ~ 35 Gy high-dose- rate brachytherapy was prescribed to point A in 4 ~ 5 weekly fractions using an iridium- 192 source. Concurrent weekly intravenous cisplatin at 30 mg/m2 was initiated on the first day of radiotherapy for over 1-h during external-beam radiotherapy. Adjuvant chemotherapy was scheduled within 4 weeks after the completion of concurrent chemo-radiotherapy and repeated 3 weeks later. Paclitaxel 150 mg/m2 was given as a 3-h infusion on day1, followed by cisplatin 35 mg/m2 with 1-h infusion on day1-2 (70 mg/m2 in total). RESULTS Fifty patients achieved complete response 4 weeks after the completion of the treatment protocol, whereas 2 patients had persistent disease. After a median follow-up period of 66 months, loco-regional (including 2 persistent disease), distant, and synchronous treatment failure occurred in 4,5, and 1, respectively. The 5-year disease-free survival, loco-regional recurrence-free survival, distant-metastasis recurrence-free survival was 80.5%, 90.3%, and 88.0%, respectively. Four of the patients died of the disease, and the 5-year overall survival was 92.1%. Most of the toxicities reported during concurrent chemo-radiotherapy were mild and transient. The occurrence of hematological toxicities elevated mildly during adjuvant chemotherapy, as 32% (16/50) and 4% (2/50) patients experienced grade 3-4 leukopenia and thrombocytopenia, respectively. Grade 3-4 late toxicities were reported in 3 patients. CONCLUSIONS The incorporation of intensity-modulated radiotherapy and adjuvant paclitaxel plus cisplatin chemotherapy were highly effective and well-tolerated in the treatment of high-risk locally advanced cervical cancer. The former yields an improved loco-regional control, whereas distant metastases could be effectively eradicated with mild toxicities when adjuvant regimen was prescribed.

The impact of para-aortic lymph node irradiation on disease-free survival in patients with cervical cancer: A systematic review and meta-analysis. Clin Transl Radiat Oncol 2022; 35:97-103. [PMID: 35669003 PMCID: PMC9166370 DOI: 10.1016/j.ctro.2022.05.006] [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: 04/01/2022] [Revised: 05/24/2022] [Accepted: 05/27/2022] [Indexed: 11/28/2022] Open
Abstract
Background Patients with locally advanced cervical cancer without para-aortic lymph node metastases (PAO-LNM) at diagnosis who undergo concurrent chemoradiotherapy are at 4-11% risk of developing PAO-LNM during follow-up. Some studies suggest a beneficial influence of elective para-aortic radiotherapy (PAO-RT) on disease-free survival (DFS) in these patients. The aim of this study was to systematically review and meta-analyse literature on the impact of PAO-RT on DFS in cervical cancer patients. Methods A systematic search of PubMed/MEDLINE and EMBASE databases was performed. The analysis included intervention studies that reported on DFS in patients with cervical cancer who received chemotherapy and pelvic radiotherapy with or without PAO-RT. From each included study, relevant study characteristics and outcome data including the hazard ratio (HR) adjusted for potential confounders were extracted. An overall pooled adjusted hazard ratio (aHR) for DFS after PAO-RT versus no PAO-RT was calculated using a random-effects model. Results A total of 2,016 articles were evaluated. Eleven articles were included in the systematic review, of which 3 were appropriate for quantitative meta-analysis. Pooling of these 3 cohorts (including 1,113 patients) demonstrated a statistically significant association between PAO-RT and DFS (pooled aHR 0.87, 95% confidence interval: 0.79-0.97). No significant heterogeneity among reported aHRs was observed (I2 = 0.0%). Conclusions This meta-analysis suggests a modest but significant beneficial impact of elective para-aortic radiotherapy on DFS in patients with locally advanced cervical cancer who undergo concurrent chemoradiotherapy. This finding based on non-randomized studies provides an imperative for further investigation in prospective controlled trials.

The prognostic significance of pretreatment squamous cell carcinoma antigen levels in cervical cancer patients treated by concurrent chemoradiation therapy and a comparison of dosimetric outcomes and clinical toxicities between tomotherapy and volumetric modulated arc therapy. Radiat Oncol 2022; 17:91.

Abstract
Background To analyze the prognostic factors associated with stage IB-IVA cervical cancer in patients who underwent concurrent chemoradiation therapy (CCRT) and to compare the clinical toxicities and dosimetric parameters of organs at risk between the different radiotherapy techniques. Methods This retrospective study enrolled 93 patients with stage IB-IVA cervical cancer who underwent definitive CCRT between April 2009 and December 2017. Nine patients (9.7%) received 3DCRT, 43 patients (46.2%) underwent VMAT, and 41 patients (44.1%) received tomotherapy, and all of them followed by brachytherapy using a 2D planning technique. The treatment outcomes and related prognostic factors were analyzed. We also compared the clinical toxicities and dosimetric parameters between the different techniques used for the last 30 patients. Results With a median follow-up of 52.0 months, the 5-year overall survival (OS), progression-free survival (PFS), locoregional recurrence–free survival (LRRFS), and distant metastases–free survival (DMFS) were analyzed. In a Cox proportional hazards regression model, pretreatment SCC Ag > 10 ng/mL was a significant prognostic factor for PFS (hazard ratio [HR] 2.20; 95% confidence interval [CI] 1.03–4.70; P = 0.041), LRRFS (HR, 3.48; 95% CI 1.07–11.26; P = 0.038), and DMFS (HR 2.80; 95% CI 1.02–7.67; P = 0.045). Increasing the rectal volume receiving a radiation dose exceeding 30 Gy (V30 of rectum; odds ratio [OR] 1.15; 95% CI 1.10–1.30; P = 0.03) was associated with a higher possibility of ≥ Grade 2 acute radiation therapy (RT)-related diarrhea. The median rectal V30 values were 56.4%, 97.5%, and 86.5% for tomotherapy, 3-dimensional conformal radiation therapy (3DCRT), and volumetric modulated arc therapy (VMAT), respectively (P < 0.001). In addition, the chance of experiencing ≥ Grade 2 acute diarrhea were 10.0%, 66.7%, and 54.5% for tomotherapy, 3DCRT, and VMAT, respectively (P = 0.029). Conclusions Patients with pretreatment SCC Ag ≤ 10 ng/mL have better PFS, LRRFS, and DMFS than those with pretreatment SCC Ag > 10 ng/mL. The rectal V30 is a significant predictor of severe acute diarrhea. Tomotherapy significantly decreased the rectal V30, reducing the severity of acute RT-related diarrhea during external beam RT. Trial registration This study was approved by the institutional review board at Kaohsiung Medical University Hospital. The registration number is KMUHIRB-E(I)-20190054 and retrospectively registered on 2019/3.

Cancer Control 2022; 29:10732748221074530. [PMID: 35196888 PMCID: PMC8883373 DOI: 10.1177/10732748221074530] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 11/17/2022] Open
Abstract
OBJECTIVE The objective is to investigate the factors that can predict early treatment response in patients receiving concurrent chemoradiotherapy (CCRT) for cervical cancer. METHODS We assessed clinical factors and treatment response in patients who underwent CCRT for cervical cancer at four time points: initial, 2.5 weeks, 6 weeks after starting CCRT, and 3 months after completing CCRT. The final treatment response was determined by positron emission tomography-computed tomography (PET-CT) 3 months after completion of CCRT. Patients were divided into two groups according to the final treatment response: complete response (CR) group or non-CR group. And the early CCRT response prediction model was developed using stepwise multivariate logistic regression analysis. RESULTS Of the 62 patients who underwent CCRT for cervical cancer, 57 patients who completed all 4 time points examinations were included in the analyses and classified as CR (n = 32) and non-CR (n = 25) group. Tumor volume and serum squamous cell carcinoma antigen (SCC Ag) of the initial, 2.5 weeks, and 6 weeks after CCRT were significantly associated with the final treatment response. For the early treatment response prediction model, we selected patient age, tumor volume, and SCC Ag measured at initial and 2.5 weeks of CCRT as variables, and the equation of the final model was yielded. Using a cutoff of 0.433, this model had a sensitivity of 72.0%, a specificity of 84.4%, and a probability of 0.8225 (P < .0001). CONCLUSION Short-term (at 2.5 weeks after starting CCRT) measurements of tumor volume and serum SCC Ag were significant predictors of response to CCRT in patients with cervical cancer.

Abstract
INTRODUCTION Node involvement is one of the main prognostic factors for cervical cancer. Para-aortic lymph node (PALN) assessment is crucial for treating advanced cervical cancer, to define irradiation fields. Objective of this study was to develop a score predicting para-aortic lymph node involvement in patients with advanced cervical cancer. PATIENTS AND METHOD We performed a multicenter, retrospective, study on 9 French centers from 2000 to 2015, including patients with advanced squamous cell cervix carcinoma who had PALN status assessed by imaging and/or by surgery. Factors associated with a risk of PALN involvement were determined by univariate and multivariate analysis using a logistic regression model. A score was then developed and validated. RESULTS A total of 1446 patients treated for cervical cancer were included. Of these, 498 had an advanced squamous cell cervical cancer. Ninety-one patients (18.3%) had positive PALN. After univariate and multivariate analysis, tumor size on pelvic MRI, initial SCC, and suspected pelvic node involvement on PET-CT were included in our score. This model allowed the population to be divided into 3 risk groups. Area under the ROC curve of the score was 0.81 (95%CI = 0.72-0.90). In the low-risk group, 9% (28/287) had PALN involvement, whereas in the high-risk group, 43% (22/51) had PALN involvement. CONCLUSION We developed a simple score predicting PALN involvement in advanced cervical cancers. Three risk groups can be defined, and patients considered to be at low risk may avoid para-aortic staging as well as extensive field irradiation.

Abstract
(1) This study investigated the prognostic impact of tumor size in patients with metastatic cervical cancer. (2) Methods: Seventy-three cervical cancer patients in our institute were stratified into two groups based on distant metastasis: para-aortic lymph node metastasis alone (IIIC2) or spread to distant visceral organs with or without para-aortic lymph node metastasis (IVB) to identify primary tumor size and concurrent chemoradiotherapy. (3) Results: The overall survival (OS) for patients with a tumor >6.9 cm in size was significantly poorer than that for patients with a tumor ≤6.9 cm in the IVB group (p = 0.0028); the corresponding five-year OS rates in patients with a tumor ≤6.9 and >6.9 cm were 53.3% and 13.4%, respectively. In the multivariate analysis, tumor size and primary treatment were significantly associated with survival in metastatic cervical cancer. (4) Conclusions: Tumor size ≤6.9 cm and concurrent chemoradiotherapy as the primary treatment were favorable prognostic factors for patients with metastatic cervical cancer.

Risk Manag Healthc Policy 2021; 14:109-116. [PMID: 33469394 PMCID: PMC7810669 DOI: 10.2147/rmhp.s273848] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2020] [Accepted: 09/28/2020] [Indexed: 11/26/2022] Open
Abstract
Objective The aim of this study was to explore whether adjuvant chemotherapy could improve prognosis for cervical cancer patients with elevated pretreatment serum squamous-cell carcinoma antigen (SCC-Ag). Methods Propensity-score matching and inverse probability of treatment weighting (IPTW) were used to ensure balanced groups for patients with (arm A) and without adjuvant chemotherapy (arm B). All patients were treated between January 2012 and December 2014 at a single center. Study outcomes were disease-free survival (DFS) and overall survival (OS). Results In total, 81 patients were included in this study. By propensity-score matching, 35 patients were included in each group (arm A and arm B). Median follow-up was 60 months in arm A and 66 months in arm B. Overall, 85.7% of patients in arm A and 71.4% of those in arm B received adjuvant radiotherapy. DFS and OS curves were similar between arms A and B (P=0.971 and 0.633, respectively). With IPTW, arm A was not associated with prognosis in terms of DFS (HR 0.946, 95% CI 0.237–3.784; P=0.938) or OS (HR 1.020, 95%CI 0.357–2.913; P=0.970). Conclusion For patients with elevated pretreatment SCC-Ag, adjuvant chemotherapy was not found to improve prognosis. Also, a considerable proportion of these patients had postoperative indications for adjuvant radiotherapy. For these cervical cancer patients with elevated pretreatment SCC-Ag, the choice of radical hysterectomy and adjuvant chemotherapy should be prudent.

The role of squamous cell carcinoma antigen (SCC Ag) in outcome prediction after concurrent chemoradiotherapy and treatment decisions for patients with cervical cancer. Radiat Oncol 2019; 14:146. [PMID: 31416463 PMCID: PMC6694518 DOI: 10.1186/s13014-019-1355-4] [Citation(s) in RCA: 39] [Impact Index Per Article: 7.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/06/2019] [Accepted: 08/06/2019] [Indexed: 11/10/2022] Open
Abstract
At present, the standard treatment approach for locally advanced cervical cancer is concurrent chemoradiotherapy (CCRT). An elevated pretreatment squamous cell carcinoma antigen (SCC Ag) level is associated with extensive tumors and poor survival for patients with cervical cancer treated with definitive CCRT. SCC Ag levels can be used to help physicians make decisions regarding surgery, avoiding the complications of double treatment modalities. Elevated SCC Ag is associated with radiotherapy resistance, and the rate of SCC Ag reduction during CCRT can predict tumor response after treatment. Moreover, the failure of SCC Ag levels to normalize posttreatment can predict tumor relapse, with a specificity higher than 70%, and adjuvant therapies should be considered for these patients. SCC Ag also plays an important role in the early detection of tumor relapse in patients with cervical cancer during follow-up after CCRT, with high sensitivity and good cost-effectiveness.

Abstract
To study the outcomes following concurrent chemoradiotherapy (CCRT) and subsequent radical surgery for locally advanced cervical cancer (LACC), analyze the relationship between imaging-diagnosed and postoperative-diagnosed lymph node (LN) involvement, and identify patients who would benefit from individualized pelvic lymphadenectomy.We retrospectively reviewed records of 410 patients who underwent CCRT followed by radical surgery for International Federation of Gynecology and Obstetrics Stage Ib2-IIIb disease. Correlations of LN size on imaging before CCRT with pathological responses after CCRT, overall survival (OS), distant metastasis-free survival (DMFS), and complications were analyzed.During a median follow-up of 51.3 months, the respective 5-year OS and DMFS were 86.7% and 88.6%, respectively. Pathological primary tumor type, LN size on imaging before CCRT, and pathologic response after CCRT were independent prognostic factors for OS. Patients with a LN ≥0.8 cm had a significantly higher residual carcinoma rate versus those with LN <0.8 cm (33% vs 22.6%, P = .032). Postoperative pathological positive LN frequencies differed significantly by LN size on imaging (LN <0.8 cm vs LN ≥0.8 cm, 3% vs 19.3%, P < .0001). Grade 1-3 lower extremity edema occurred in 23.9% of cases; no grade 3-4 gastrointestinal and genitourinary toxicities were observed.CCRT followed by radical surgery for LACC yielded encouraging outcomes without unacceptable complications. Additionally, patients with a LN <0.8 cm on imaging before CCRT had a very low risk of postoperative pathological positive LN identification. Individualized pelvic lymphadenectomy (e.g., omitting or limiting the extent of LN dissection) might be an alternative option for some patients with a low risk of LN metastasis.

Abstract
OBJECTIVES This study aimed to identify prognostic factors for para-aortic lymph node (PALN) recurrence and their effect on survival outcomes in patients with pelvic node-positive squamous cell carcinoma (SCC) of the cervix treated with definitive concurrent chemoradiotherapy (CCRT). MATERIALS AND METHODS Of the 116 patients with biopsy-proven SCC of the uterine cervix who underwent primary CCRT from 2007 to 2012, 48 patients with pelvic LN metastasis detected by [F]-fluorodeoxyglucose positron emission tomography (FDG PET) were retrospectively analyzed. Patients with evidence of para-aortic lymphadenopathy were excluded. The whole pelvis was the standard irradiation field for all patients. The associations of age, stage, serum SCC antigen (SCC-Ag) level, maximum standardized uptake value (SUVmax), hemoglobin level, overall treatment time, adjuvant chemotherapy, and pelvic LN status with PALN recurrence and survival outcomes were evaluated. RESULTS At a median follow-up of 34.0 months (range, 8-73 months), 10 (20.8%) patients had developed PALN recurrences. The relationship between pelvic LN FDG uptake and PALN recurrence was evaluated by the cutoff value (SUVmax = 3.85) determined by receiver operating characteristic curve analysis. The independent risk factors for PALN recurrence were FDG-avid pelvic LN (SUVPLN) greater than 3.85 (hazard ratio, 13.12; P = 0.025) and posttreatment SCC-Ag level greater than 2.0 (ng/mL) (hazard ratio, 20.69; P = 0.019). Patients with an SUVPLN greater than 3.85 were found to have significantly worse 5-year distant metastasis-free (51.0% vs 79.0%, P = 0.016) and progression-free survival (38.7% vs 67.3%, P = 0.011) than those with an SUVPLN less than or equal to 3.85. CONCLUSIONS SUVPLN is a statistically significant prognostic factor of PALN recurrence and survival after definitive CCRT for pelvic node-positive SCC of the uterine cervix.

Abstract
OBJECTIVE To externally validate the prognostic models for predicting the time-dependent outcome in patients with locally advanced cervical cancer (LACC) who were treated with concurrent chemoradiotherapy in an independent cohort. METHODS A historical cohort of 297 women with LACC who were treated with radical concurrent chemoradiotherapy from 1999 to 2014 at the 12 de Octubre University Hospital (H12O), Madrid, Spain. The external validity of prognostic models was quantified regarding discrimination, calibration, measures of overall performance, and decision curve analyses. RESULTS The review identified 8 studies containing 13 prognostic models. Different (International Federation of Gynecology and Obstetrics [FIGO] stages, parametrium involvement, hydronephrosis, location of positive nodes, and race) but related cohorts with validation cohort (5-year overall survival [OS]=70%; 5-year disease-free survival [DFS]=64%; average age of 50; and over 79% squamous cell) were evaluated. The following models exhibited good external validity in terms of discrimination and calibration but limited clinical utility: the OS model at 3 year from Kidd et al.'s study (area under the receiver operating characteristic curve [AUROC]=0.69; threshold of clinical utility [TCU] between 36% and 50%), the models of DFS at 1 year from Kidd et al.'s study (AUROC=0.64; TCU between 24% and 32%) and 2 years from Rose et al.'s study (AUROC=0.70; TCU between 19% and 58%) and the distant recurrence model at 5 years from Kang et al.'s study (AUROC=0.67; TCU between 12% and 36%). CONCLUSION The external validation revealed the statistical and clinical usefulness of 4 prognostic models published in the literature.

Abstract
OBJECTIVE To evaluate the effects of prophylactic sub-renal vein radiotherapy (SRVRT) using intensity-modulated radiotherapy (IMRT) for cervical cancer. METHODS A total of 206 patients with FIGO stage IB2-IVA cervical cancer and negative para-aortic lymph nodes (PALNs) who underwent pelvic IMRT (PRT) or SRVRT between 2004 and 2013 at our institution were reviewed. SRVRT cranially extended the PRT field for PALNs up to the left renal vein level. The prescribed dose was consistent 50.4Gy in 28 fractions. RESULTS Overall, 110 and 96 patients underwent PRT and SRVRT, respectively. The SRVRT group had more advanced disease based on FIGO stage and positive pelvic lymph nodes (PLNs). The median follow-up time was 60months (range, 7-143). For the total study population, the 5-year PALN recurrence-free survival (PARFS) and overall survival (OS) for PRT vs. SRVRT were 87.6% vs. 97.9% (p=0.03) and 74.5% vs. 87.8% (p=0.04), respectively. In patients with FIGO III-IVA or positive PLNs, the 5-year PARFS and OS for PRT vs. SRVRT were 80.1% vs. 96.4% (p=0.02) and 58.1% vs. 83.5% (p=0.012), respectively. However, there were no significant differences in these outcomes for patients with FIGO IB-IIB and negative PLNs. In a multivariate analysis, only SRVRT was associated with better PARFS (HR, 0.21; 95% CI, 0.06-0.78; p=0.02). The SRVRT did not significantly increase severe late toxicities. CONCLUSION Prophylactic SRVRT using IMRT reduced PALN recurrence with tolerable toxicities, supporting the application of risk-based radiation fields for cervical cancer.

Abstract
Patients with locally advanced cervical cancer (LACC) are at risk of para-aortic lymph node (PALN) metastasis. Pelvic concurrent chemoradiotherapy, the current standard treatment for LACC, has a PALN failure rate of 9% according to the Radiation Therapy Oncology Group Trial 90-01, suggesting that it may not completely eliminate all microscopic tumors in the PALNs. To minimize the toxicities associated with conventional prophylactic extended-field radiotherapy, our institute use prophylactic semiextended field radiotherapy that includes only the PALNs below the level of the renal vessels. Use of intensity-modulated radiotherapy (IMRT) is another means of reducing the incidence of toxicity. This study evaluated the safety and efficacy of prophylactic semiextended field IMRT (SEF-IMRT) and concurrent cisplatin chemotherapy in patients with LACC.We retrospectively assessed survival and toxicity in 76 patients with stage IB2-IVA cervical cancer and negative PALNs who received prophylactic SEF-IMRT and concurrent weekly cisplatin (40 mg/m) between 2004 and 2013. The region targeted by SEF-IMRT included the PALNs below the level of the renal vessels, and the prescribed dose was 50.4 Gy in 28 fractions. Brachytherapy was administered at a dose of 30 Gy in 6 fractions. Survival outcomes were calculated by using the Kaplan-Meier method, and acute and late toxicities were scored according to the Common Terminology Criteria for Adverse Events, version 3.0.All patients completed the planned SEF-IMRT, as well as brachytherapy. Acute grade ≥3 gastrointestinal, genitourinary, and hematologic toxicities were observed in 2, 0, and 41 patients, respectively. The median follow-up time after SEF-IMRT was 55 (range, 11-124) months. Eight patients developed out-field distant recurrences without PALN failure, and 1 patient experienced out-field PALN failure with simultaneous distant metastasis. No patients had late genitourinary toxicities, and 3 patients had late grade 3 gastrointestinal toxicities. The 5-year overall survival, disease-free survival, local failure-free survival, regional failure-free survival, PALN failure-free survival, and distant metastasis-free survival rates were 85.0%, 84.4%, 96.0%, 97.3%, 98.6%, and 88.4%, respectively.For patients with LACC, prophylactic PALN irradiation up to the level of the renal vessels reduced PALN recurrence and resulted in favorable outcomes with few severe toxicities.

Abstract
PURPOSE The aim of this prospective study was to assess the usefulness of (18)F-FDG PET/CT performed before and during treatment for predicting treatment failure in patients with advanced squamous cell carcinoma of the uterine cervix treated with concurrent chemoradiotherapy (CCRT). METHODS Patients with cervical squamous cell carcinoma, International Federation of Gynecology and Obstetrics stage III/IVA or positive pelvic or paraaortic lymph node (LN) metastasis without other distant metastasis on PET/CT entering a randomized trial of CCRT (AGOG 09-001) were eligible. PET/CT scans were performed at baseline, during week 3 of CCRT and 2 - 3 months after CCRT. PET/CT parameters were correlated with sites of failure and overall survival (OS). The resulting predictors developed from the study cohort were validated on two independent datasets using area under the curve values, sensitivities and specificities. RESULTS With a median follow-up of 54 months for survivors, 20 (36 %) of the 55 eligible patients were proven to have treatment failure. Sites of failure were local in five, regional in 11, and distant in 11. Four predictors for local failure, three for regional failure, and four for distant failures were identified. After validation with two independent cohorts of 31 and 105 patients, we consider the following as clinically useful predictors: pretreatment metabolic tumour volume (MTV) and during-treatment cervical tumour MTV for local failure; during-treatment SUVnode (maximum standardized uptake value of LNs) for regional and distant failure, and during-treatment MTV for distant failure. During-treatment SUVnode (P = .001) and cervical tumour MTVratio (P = .004) were independent significant predictors of OS by stepwise Cox regression. CONCLUSION PET/CT imaging before and during treatment is useful for predicting failure sites and OS, making tailored therapeutic modifications feasible with potential outcome improvement during primary therapy.

Abstract
OBJECTIVE A recent randomized trial demonstrated that concurrent chemoradiotherapy (CCRT) with weekly cisplatin and gemcitabine, followed by two adjuvant cycles of cisplatin and gemcitabine improved survival for advanced cervical cancer patients. An Asian Gynecologic Oncology Group (AGOG) study was designed to determine whether only adding gemcitabine in the chemoradiation phase without adjuvant chemotherapy could improve survival. METHODS Between March 2009 and March 2013, 74 eligible patients with International Federation of Obstetrics and Gynecology stage III/IVA cervical cancer or stage I/II with positive pelvic/para-aortic nodal metastasis were enrolled. Thirty-seven patients were randomized to arm C (weekly cisplatin 40mg/m(2)) and 37 patients were randomized to arm CG (weekly cisplatin 40mg/m(2) and gemcitabine 125mg/m(2)), for six cycles. Six eligible patients were excluded before the beginning of treatment. RESULTS An interim analysis showed superimposable progression-free (PFS) and overall survival (OS), a decision of closing accrual was made. A 3-year PFS was similar in both arms (arm C 65.1% vs. arm CG 71.0%, p=0.71), and a 3-year OS was 74.1% in arm C vs. 85.9% in arm CG (p=0.89), but crossed over at 5years. Grade 2-4 hematological toxicities, including neutropenia (p=0.028) and thrombocytopenia (p=0.001), were more frequent in arm CG than arm C. CONCLUSIONS Despite limitation in power, it suggests that only adding gemcitabine at the CCRT phase does not provide substantially superior results, but treatment toxicities could increase. Further studies are required to determine the role of post-CCRT adjuvant chemotherapy in advanced cervical cancer.

Abstract
ObjectiveThe objective of this study was to assess prospectively the clinical outcomes of low-dose prophylactic extended-field, intensity-modulated radiotherapy (IMRT) plus concurrent weekly cisplatin for patients with stage IB2-IIIB cervical cancer, positive pelvic lymph nodes (PLNs), and negative para-aortic lymph nodes (PALNs).MethodsThirty-two patients with stage IB2-IIIB cervical cancer with positive PLN and negative PALN were included prospectively. All lymph nodes were assessed with positron emission tomography. The PALN field, including lymphatics from the superior border of L1 to the L4-L5 interphase, was irradiated concurrently with pelvic IMRT with a prescribed dose of 40 Gy in 25 fractions. Chemotherapy consisted of cisplatin delivered weekly at a dose of 40 mg/m2. Using historical controls treated with pelvic radiotherapy, the survival curves were compared to assess the difference between the 2 treatment periods.ResultsThirty-one patients completed the allocated extended-field IMRT, and all finished the planned pelvic IMRT and brachytherapy. Acute ≥ grade 3 gastrointestinal, genitourinary, and hematologic toxicities were seen in 2, 1, and 18 patients, respectively. During a median follow-up of 33 months, 5 patients developed out-field distant recurrences. One patient had a late grade 3 gastrointestinal complication, and 1 patient had genitourinary toxicity. The 3-year actuarial overall survival, disease-free survival, and distant metastasis–free survival for the study cohort and historic controls were 87% versus 62% (P = 0.02), 82% versus 54% (P = 0.02), and 79% versus 57% (P = 0.01), respectively.ConclusionsExtended-field IMRT of 40 Gy to the PALN plus concurrent cisplatin can effectively eradicate subclinical disease at the PALN and improve the outcome for patients with PLN-positive stage IB2-IIIB cervical cancer.

Abstract
PURPOSE OF REVIEW This review is to inform the reader about the current situation with regard to treatment of cervical cancer in Africa and the barriers and complexities faced in most African countries. It also reviews the natural history of cervical cancer, the new 2009 International Federation of Gynecology and Obstetrics staging, and current treatment guidelines for cervical cancer. RECENT FINDINGS There have been no dramatic new findings in the treatment of cervical cancer other than newer approaches to fertility-sparing surgery and the addition of concomitant chemotherapy to radiation for advanced cervical cancer and the data from randomized trials that have shown an improved overall and disease-free survival. The most important new findings in cervical cancer pertain to cervical cancer prevention strategies, which included using alternative approaches to cytology and the introduction of human papillomavirus (HPV) vaccination. SUMMARY Cervical cancer is the commonest cancer cause of death among women in developing countries and efforts to prevent the disease using newer approaches and HPV vaccination should be implemented. Detection of cervical cancer at an early stage is associated with excellent survival but most women in developing countries present with advanced and often untreatable disease. The ratio between incidence and mortality from cervical cancer remains very high, largely due to lack of access to appropriate anticancer therapies in African countries.

Abstract
The International Federation of Gynecology and Obstetrics (FIGO) staging of tumours of the uterine corpus, cervix and vulva was revised in 2009. The greatest impact of the revised staging was on carcinomas of the uterine corpus. Uterine sarcomas are now staged separately. Changes to the staging system for vulvar carcinomas largely reflect the significance of lymph node status. Only minor amendments have been introduced for cervical carcinomas, which remain the only gynaecological tumours to be staged clinically. These revisions, based on recent evidence, require careful, more detailed assessment of several histological parameters at each anatomical site. The present review deals with the evidence and rationale underpinning the revisions, and includes practical guidance on tumour staging. This covers the assessment and measurement of myoinvasion and evaluation of cervical, parametrial, serosal and vaginal involvement in carcinomas of the uterine corpus; the identification and accurate measurement of stromal invasion in cervical and vulvar carcinomas; the assessment of unusual variants of carcinoma at each of these sites; and the assessment of lymph node involvement.

Abstract
OBJECTIVE A change has recently been made to the Federation of Gynecology and Obstetrics (FIGO) staging system for cervical cancer to account for size within stage IIA cancers. This study was designed to investigate the impact of size within stage I-IIIB cervical carcinoma, and to validate these changes. METHODS The Surveillance, Epidemiology, and End Results Program database was used to extract data on patients from 1988 to 2008. Patients were included who had information recorded regarding stage, size, and type of treatment received. They were then stratified by stage and size, and analyzed for cause-specific survival (CSS) using Kaplan Meier estimates, as well as hazard ratios using Cox proportional hazards regression modeling. RESULTS A total of 18,649 cases were evaluated. All stages evaluated demonstrated improved CSS on Kaplan Meier estimates for smaller tumor sizes (largest p=0.0003). Hazard ratios were significantly worse for larger tumor sizes on both univariate and multivariate modeling. Specifically, stage IIA cancers demonstrated a hazard ratio of 2.0 on univariate, and 1.69 on multivariate analysis (C.I. 1.46-2.75, p<0.0001 and C.I. 1.20-2.38, p=0.0025, respectively). Further size subdivisions of 2 and 4cm for stage I, 4cm for stage IIB, and 4 and 6cm for stage IIIB also maintained prognostic significance. On multivariate analysis within each stage, size was the only variable to maintain independent significance in all stages evaluated. CONCLUSIONS Size is independently prognostic within each stage in cervical cancer, validating the recent changes to the FIGO staging system.

Abstract
PURPOSE To study the prognostic value of human papillomavirus (HPV) genotypes in patients with advanced cervical cancer treated with radiation therapy (RT) alone or concurrent chemoradiation therapy (CCRT). METHODS AND MATERIALS Between August 1993 and May 2000, 327 patients with advanced squamous cell carcinoma of the cervix (International Federation of Gynecology and Obstetrics stage III/IVA or stage IIB with positive lymph nodes) were eligible for this study. HPV genotypes were determined using the Easychip® HPV genechip. Outcomes were analyzed using Kaplan-Meier survival analysis and the Cox proportional hazards model. RESULTS We detected 22 HPV genotypes in 323 (98.8%) patients. The leading 4 types were HPV16, 58, 18, and 33. The 5-year overall and disease-specific survival estimates for the entire cohort were 41.9% and 51.4%, respectively. CCRT improved the 5-year disease-specific survival by an absolute 9.8%, but this was not statistically significant (P=.089). There was a significant improvement in disease-specific survival in the CCRT group for HPV18-positive (60.9% vs 30.4%, P=.019) and HPV58-positive (69.3% vs 48.9%, P=.026) patients compared with the RT alone group. In contrast, the differences in survival with CCRT compared with RT alone in the HPV16-positive and HPV-33 positive subgroups were not statistically significant (P=.86 and P=.53, respectively). An improved disease-specific survival was observed for CCRT treated patients infected with both HPV16 and HPV18, but these differenced also were not statistically significant. CONCLUSIONS The HPV genotype may be a useful predictive factor for the effect of CCRT in patients with advanced squamous cell carcinoma of the cervix. Verifying these results in prospective trials could have an impact on tailoring future treatment based on HPV genotype.

Abstract
OBJECTIVE Patients with cervical cancer and supraclavicular lymph nodes (SLN) recurrence have a poor but heterogeneous prognosis. The aim of this study was to identify potential prognostic factors - including FDG-PET results - that may affect survival and treatment outcomes in patients with this group of patients. METHODS Between January 2001 and December 2008, we identified a total of 31 consecutive patients with cervical cancer who had evidence of SLN recurrence. All participants underwent FDG-PET. Survival was measured from the date of documented SLN recurrence. The latency period was defined as the length of time from the date of first diagnosis to the date of SLN recurrence. RESULTS The median follow-up time was 22.8 months (range: 4.7-105.1). The 3- and 5-year survival rates were 41% and 27.3%, respectively. Patients with intermediate SUV values (between 4.3 and 8) had a significantly better prognosis than subjects with both high (>8) or low (<4.3) SUV values (p=0.004). Latency period <2 years, SCC-Ag levels ≥ 4ng/mL, recurrence extend beyond SLN, and SUV of <4.3 >8 were significant adverse prognostic factors by multivariate analysis. The 3-year overall survival (OS) rate of patients carrying 0-1 adverse prognostic factors was 90% (low-risk group), while 3-year OS rates for intermediate-risk group (2 factors) and high-risk group (3-4 factors) were 30% and 0%, respectively (p=0.001). CONCLUSION Our results justify the use of PET (accurate extent of relapse and SUV) as a prognostic tool in patients with cervical cancer and SLN recurrence.

Prognostic value of pretreatment carcinoembryonic antigen after definitive radiotherapy with or without concurrent chemotherapy for squamous cell carcinoma of the uterine cervix. Int J Radiat Oncol Biol Phys 2010; 81:1105-13.

Abstract
PURPOSE To evaluate whether pretreatment carcinoembryonic antigen (CEA) levels have a prognostic role in patients after definitive radiotherapy for squamous cell carcinoma (SCC) of the uterine cervix. METHODS AND MATERIALS A retrospective study of 550 patients was performed. The SCC antigen (SCC-Ag) and CEA levels were regarded as elevated when they were ≥2 and ≥5 ng/mL, respectively. A total of 208 patients underwent concurrent chemoradiotherapy (CCRT). The Kaplan-Meier method was used to calculate the distant metastasis (DM), local failure (LF), disease-free survival (DFS), and overall survival (OS) rates. Multivariate analysis was performed using the Cox proportional hazards model. The hazard ratio (HR) with 95% confidence interval (CI) was evaluated for the risk of a poor prognosis. RESULTS Compared with the patients with normal CEA/SCC-Ag levels, CEA levels ≥10 ng/mL but without elevated SCC-Ag levels was an independent factor for LF (HR, 51.81; 95% CI, 11.51-233.23; p < .001), DM (HR, 6.04; 95% CI, 1.58-23.01; p = .008), DFS (HR, 10.17; 95% CI, 3.18-32.56; p < .001), and OS (HR, 5.75; 95% CI, 1.82-18.18; p = .003) after RT alone. However, no significant role for CEA was noted in patients with SCC-Ag levels ≥2 ng/mL. In patients undergoing CCRT, a CEA level ≥10 ng/mL was an independent factor for LF (HR, 2.50; 95% CI, 1.01-6.21; p = .047), DM (HR, 3.41; 95% CI, 1.56-7.46; p = .002), DFS (HR, 2.73; 95% CI, 1.39-5.36; p = .003), and OS (HR, 3.93; 95% CI 1.99-7.75; p < .001). A SCC-Ag level of ≥40 ng/mL was another prognostic factor for DM, DFS, and OS in patients undergoing not only CCRT, but also RT alone. The 5-year OS rate for CCRT patients with CEA <10 ng/mL and ≥10 ng/mL was 75.3% and 35.8%, respectively (p < .001). CCRT was an independent factor for better OS (HR, 0.69; 95% CI, 0.50-0.97; p = .034). CONCLUSION Pretreatment CEA levels in patients with SCC of the uterine cervix provide complementary information for predicting LF, DM, DFS, and OS, except for in patients with abnormal SCC-Ag levels before RT alone. More aggressive therapy might be advisable for patients with CEA levels of ≥10 ng/mL.

Abstract
PURPOSE To study the outcomes of patients with adenocarcinoma/adenosquamous carcinoma (AC/ASC) of the cervix primarily treated with radiotherapy (RT), identify the prognostic factors, and evaluate the efficacy of concurrent chemoradiotherapy (CCRT) or salvage surgery. METHODS AND MATERIALS A total of 148 patients with Stage I-IVA AC/ASC of cervix after full-course definitive RT were included. Of the 148 patients, 77% had advanced stage disease. Treatment failure was categorized as either distant or local failure. Local failure was further separated into persistent tumor or local relapse after complete remission. The effectiveness of CCRT with cisplatin and/or paclitaxel was examined, and the surgical salvage rate for local failure was reviewed. RESULTS The 5-year relapse-free survival rate was 68%, 38%, 49%, 30%, and 0% for those with Stage IB/IIA nonbulky, IB/IIA bulky, IIB, III, and IVA disease, respectively, and appeared inferior to that of those with squamous cell carcinoma of the cervix treated using the same RT protocol. Incomplete tumor regression after RT, a low hemoglobin level, and positive lymph node metastasis were independent poor prognostic factors for relapse-free survival. CCRT with weekly cisplatinum did not improve the outcome for our AC/ASC patients. Salvage surgery rescued 30% of patients with persistent disease. CONCLUSION Patients with AC/ASC of the cervix primarily treated with RT had inferior outcomes compared to those with squamous cell carcinoma. Incomplete tumor regression after RT was the most important prognostic factor for local failure. Salvage surgery for patients with persistent tumor should be encouraged for selected patients. Our results did not demonstrate a benefit of CCRT with cisplatin for this disease.

Abstract
PURPOSE The purpose of this study was to develop a nomogram capable of predicting the probability of 5-year survival after radical radiotherapy (RT) without chemotherapy for uterine cervical cancer. METHODS AND MATERIALS We retrospectively analyzed 549 patients that underwent radical RT for uterine cervical cancer between March 1994 and April 2002 at our institution. Multivariate analysis using Cox proportional hazards regression was performed and this Cox model was used as the basis for the devised nomogram. The model was internally validated for discrimination and calibration by bootstrap resampling. RESULTS By multivariate regression analysis, the model showed that age, hemoglobin level before RT, Fédération Internationale de Gynécologie Obstétrique (FIGO) stage, maximal tumor diameter, lymph node status, and RT dose at Point A significantly predicted overall survival. The survival prediction model demonstrated good calibration and discrimination. The bootstrap-corrected concordance index was 0.67. The predictive ability of the nomogram proved to be superior to FIGO stage (p=0.01). CONCLUSIONS The devised nomogram offers a significantly better level of discrimination than the FIGO staging system. In particular, it improves predictions of survival probability and could be useful for counseling patients, choosing treatment modalities and schedules, and designing clinical trials. However, before this nomogram is used clinically, it should be externally validated.

Abstract
PURPOSE To develop a prediction model to identify a low-risk group for distant recurrence in patients with locally advanced cervical cancer treated by concurrent chemoradiation. METHODS AND MATERIALS Prospectively, 62 patients with locally advanced cervical cancer were recruited as a training cohort. Clinical variables and parameters obtained from positron emission tomography (PET) and magnetic resonance imaging were analyzed by logistic regression. For the test set, 54 patients were recruited independently. To identify the low-risk group, negative likelihood ratio (LR) less than 0.2 was set to be a cutoff. RESULTS Among the training cohort, multivariate logistic analysis revealed that advanced International Federation of Gynecology and Obstetrics (FIGO) stage and a high serum squamous cancer cell (SCC) antigen level were significant risk factors (p=0.015 and 0.025, respectively). Using the two parameters, criteria to determine a low-risk subset for distant recurrence were postulated: (1) FIGO Stage IIB or less and (2) pretreatment SCC<2.4 (Model A). Positive pelvic node on PET completely predicted all cases with distant recurrence and thus was considered as another prediction model (Model B). In the test cohort, although Model A did not showed diagnostic performance, Model B completely predicted all cases with distant recurrence and showed a sensitivity of 100% with negative LR of 0. Across the training and test cohort (n=116), the false negative rate was 0 (95% confidence interval 0%-7.6%). CONCLUSIONS Positive pelvic node on PET is a useful marker in prediction of distant recurrence in patients with locally advanced cervical cancer who are treated with concurrent chemoradiation.

Cancer 2010; 116:1469-75.

Abstract
BACKGROUND The objective of the current study was to evaluate the prognostic significance of the maximum standardized uptake value (SUV(max)) of F-18 fluorodeoxyglucose (FDG) as measured by positron emission tomography (PET) in pelvic lymph nodes in patients with cervical cancer. METHODS The authors studied cervical cancer patients with pelvic lymph node metastasis, as evidenced on FDG-PET, who were treated between November 2003 and October 2008. The maximum dimension and SUV(max) for the most FDG-avid pelvic lymph node (SUV(PLN)) and the SUV(max) of the primary cervical tumor (SUV(cervix)) were recorded from the FDG-PET/computed tomography (CT) scan. The SUV(PLN) was analyzed for its association with treatment response, pelvic disease recurrence, disease-specific survival, and overall survival. RESULTS The population was comprised of 83 women with International Federation of Gynecology and Obstetrics (FIGO) stages IB1 to IIIB cervical cancer. The average SUV(PLN) was 6.9 (range, 2.1-33.0), whereas the average SUV(cervix) was 14.0 (range, 3.2-38.4). The SUV(cervix) and SUV(PLN) were found to be weakly correlated (correlation coefficient [R(2)] = 0.301). The average size of the pelvic lymph nodes was 2.1 cm (range, 0.6-7.9 cm), and was also found to be only weakly associated with the SUV(PLN) (R(2) = 0.225). The SUV(PLN) was found to be correlated with an increased risk of persistent disease after treatment (P = .0025), specifically within the pelvic lymph node region (P = .0003). The SUV(PLN) was found to be predictive of an increased risk of ever developing pelvic disease recurrence (P = .0035). Patients with a higher SUV(PLN) were found to have significantly worse disease-specific (P = .0230) and overall survival (P = .0378) using Kaplan-Meier evaluation. A Cox proportional hazards model for the risk of pelvic disease recurrence was performed including SUV(PLN,) patient age, and tumor stage, and found only an increased SUV(PLN) to be an independent predictor. CONCLUSIONS SUV(PLN) is a prognostic biomarker, predicting treatment response, pelvic recurrence risk, and disease-specific survival in patients with cervical cancer.

Clinical effect of human papillomavirus genotypes in patients with cervical cancer undergoing primary radiotherapy. Int J Radiat Oncol Biol Phys 2010; 78:1111-20. [PMID: 20231068 DOI: 10.1016/j.ijrobp.2009.09.021] [Citation(s) in RCA: 40] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2009] [Revised: 09/04/2009] [Accepted: 09/04/2009] [Indexed: 11/24/2022]
Abstract
PURPOSE To study the prognostic value of the human papillomavirus (HPV) genotypes in cervical cancer patients undergoing radiotherapy. PATIENTS AND METHODS A total of 1,010 patients with cervical cancer after radiotherapy between 1993 and 2000 were eligible for this study. The HPV genotypes were determined by a genechip, which detects 38 types of HPV. The patient characteristics and treatment outcomes were analyzed using the Cox regression hazard model and classification and regression tree decision tree method. RESULTS A total of 25 genotypes of HPV were detected in 992 specimens (98.2%). The leading 8 types were HPV16, 58, 18, 33, 52, 39, 31, and 45. These types belong to two high-risk HPV species: alpha-7 (HPV18, 39, 45) and alpha-9 (HPV16, 31, 33, 52, 58). Three HPV-based risk groups, which were independent of established prognostic factors, such as International Federation of Gynecology and Obstetrics stage, age, pathologic features, squamous cell carcinoma antigen, and lymph node metastasis, were associated with the survival outcomes. The high-risk group consisted of the patients without HPV infection or the ones infected with the alpha-7 species only. Patients co-infected with the alpha-7 and alpha-9 species belonged to the medium-risk group, and the others were included in the low-risk group. CONCLUSION The results of the present study have confirmed the prognostic value of HPV genotypes in cervical cancer treated with radiotherapy. The different effect of the alpha-7 and alpha-9 species on the radiation response deserves additional exploration.

Abstract
OBJECTIVE On the basis of outcome data from concurrent chemoradiotherapy (CCRT) for locally advanced cervical squamous cell carcinoma, the authors developed a nomogram for predicting survival outcome. STUDY DESIGN Two hundred fifty-one eligible patients with International Federation of Gynecology and Obstetrics stage IIB-IVA squamous cell carcinoma of the uterine cervix who underwent CCRT were included for the construction of the nomogram. Predictor variables included age, serum squamous cell carcinoma antigen, tumor size, parametrium invasion, hydronephrosis, bladder/rectum invasion, and lymph node metastases. Internal validation of the nomogram was performed. RESULTS A nomogram for predicting the 5 year overall survival for these patients was constructed on the basis of a Cox regression model from 7 parameters. The concordance index was 0.69. CONCLUSION This nomogram is a predictive tool, upon external validation, that can be used to counsel patients in predicting outcomes. The discriminatory ability of the nomogram indicates that this population should not be considered homogeneous with respect to risk of death.

Factors for predicting rectal dose of high-dose-rate intracavitary brachytherapy after pelvic irradiation in patients with cervical cancer: a retrospective study with radiography-based dosimetry. Int J Radiat Oncol Biol Phys 2009; 76:490-5. [PMID: 19467795 DOI: 10.1016/j.ijrobp.2009.02.018] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2008] [Revised: 12/22/2008] [Accepted: 02/05/2009] [Indexed: 11/18/2022]
Abstract
PURPOSE To evaluate the predictive factors for rectal dose of the first fraction of high-dose-rate intracavitary brachytherapy (HDR-ICBT) in patients with cervical cancer. METHODS AND MATERIALS From March 1993 through February 2008, 946 patients undergoing pelvic irradiation and HDR-ICBT were analyzed. Examination under anesthesia (EUA) at the first implantation of the applicator was usually performed in the early period. Rectal point was determined radiographically according to the 38th Report of the International Commission of Radiation Units and Measurements (ICRU). The ICRU rectal dose (PRD) as a percentage of point A dose was calculated; multiple linear regression models were used to predict PRD. RESULTS Factors influencing successful rectal dose calculation were EUA (p < 0.001) and absence of diabetes (p = 0.047). Age (p < 0.001), body weight (p = 0.002), diabetes (p = 0.020), and EUA (p < 0.001) were independent factors for the PRD. The predictive equation derived from the regression model was PRD (%) = 57.002 + 0.443 x age (years) - 0.257 x body weight (kg) + 6.028 x diabetes (no: 0; yes: 1) - 8.325 x EUA (no: 0; yes: 1) CONCLUSION Rectal dose at the first fraction of HDR-ICBT is positively influenced by age and diabetes, and negatively correlated with EUA and body weight. A small fraction size at point A may be considered in patients with a potentially high rectal dose to reduce the biologically effective dose if the ICRU rectal dose has not been immediately obtained in the first fraction of HDR-ICBT.

Abstract
PURPOSE To evaluate the pretreatment risk factors of para-aortic lymph node (PALN) recurrence after primary radiotherapy for cervical cancer. METHODS AND MATERIALS Between May 1992 and January 2006, the data from 758 patients with squamous cell carcinoma of the uterine cervix were retrospectively analyzed. No patient had undergone PALN radiotherapy as their initial treatment. PALN recurrence was diagnosed by computed tomography. PALN relapse-free status was determined clinically or radiographically. We analyzed the actuarial rates of PALN recurrence using Kaplan-Meier curves. Multivariate analyses were performed with Cox regression models. RESULTS Of the 758 patients, 38 (5%) and 42 (6%) had isolated and nonisolated PALN recurrences after a median follow-up of 50 months (range, 2-159 months), respectively. The 3-year and 5-year overall survival rate after PALN recurrence was 35% and 28%, respectively. A squamous cell carcinoma antigen (SCC-Ag) level >40 ng/mL (p <0.001), advanced parametrial involvement (score 4-6; p = 0.002), and the presence of pelvic lymphadenopathy (p = 0.007) were independent factors associated with PALN relapse on multivariate analysis. The 5-year PALN recurrence rate in patients with a SCC-Ag level >40 ng/mL, SCC-Ag level of 20-40 ng/mL, parametrial score of 4-6, pelvic lymphadenopathy, and no risk factors was 57%, 22%, 34%, 37%, and 9%, respectively. CONCLUSIONS Patients with squamous cell carcinoma of the uterine cervix and a high SCC-Ag level, pelvic lymphadenopathy, or advanced PM involvement were predisposed to PALN recurrence after definitive radiotherapy. More intensive follow-up schedules are suggested for early detection and salvage in high-risk patients.

Abstract
PURPOSE To test, though a control-cohort study, the hypothesis that concurrent chemoradiotherapy (CCRT) using weekly cisplatin, plus high-dose rate intracavitary brachytherapy (HDRICB) is superior to radiation (RT) alone in patients with advanced cervical cancer. METHODS AND MATERIALS A total of 171 patients with Stage IIB-III cervical cancer were enrolled in this study. Seventy patients were treated with CCRT and the results were compared with those of 101 patients who had been treated with RT using the same protocol at an early period. RT consisted of 45 Gy in 25 fractions to the whole pelvis, followed by a 12.6-Gy boost to the parametrium. Four courses of HDRICB using 6.0 Gy to Point A were performed. Chemotherapy consisted of weekly cisplatin at a dose of 40 mg/m(2) for 5-6 cycles. RESULTS The 4-year actuarial survival was 74% for the CCRT group and 68% for the RT group (p = 0.60). The 4-year pelvic relapse-free survival was 87% for the CCRT group and 85% for the RT group (p = 0.37). The 4-year distant metastases-free survival was 75% for the CCRT group and 76% for the RT group (p = 0.44). The cumulative incidence of gastrointestinal and genitourinary injuries of grade 3 or above was 14.3% for the CCRT group and 7.9% for the RT group (p = 0.19). CONCLUSION This study did not show a survival benefit of CCRT with weekly cisplatin and HDRICB for Stage II-III cervical cancer, nor did it demonstrate a significant increase of late complications when comparing with RT alone.

Cyclooxygenase-2 impairs treatment effects of radiotherapy for cervical cancer by inhibition of radiation-induced apoptosis. Int J Radiat Oncol Biol Phys 2006; 66:1347-55.

Abstract
PURPOSE Cyclooxygenase-2 (COX-2) plays a pivotal role in regulation of radiation-induced apoptosis. The aim of this study was to analyze the relationship between COX-2 expression and postradiotherapy outcomes of patients with cervical cancer. METHODS AND MATERIALS Biopsy specimens from 47 consecutive patients who had undergone definitive radiotherapy alone or radiotherapy combined with chemotherapy between October 2002 and November 2004 were investigated. RESULTS The COX-2 expression rate of the pretreatment samples was 46.1% +/- 21.0%, and the apoptotic index (AI) 1 week after start of radiotherapy was 2.1% +/- 0.9%. There was a significant negative correlation between the pretreatment COX-2 expression and the AI during radiotherapy (r = -0.52, p = 0.0002). Complete response rates were 59% for COX-2-positive patients compared with 80% for COX-2-negative patients (p = 0.12). The 2-year local control rate for COX-2-positive patients was 71.3%, whereas the corresponding rate for COX-2-negative patients was 96.0% (p = 0.06). CONCLUSIONS To the best of our knowledge, this is the first report to prove clinically that COX-2 can make cervical squamous cell carcinomas more refractory to radiotherapy by inhibition of radiation-induced apoptosis. Furthermore, expression of COX-2 may be a good indicator to predict local tumor control after radiotherapy. Although long-term results are ultimately needed, the combination therapy of radiotherapy with use of a COX-2 inhibitor could yield improved outcomes for patients with COX-2 expressing cervical cancer.
