Abstract
Cervical cancer is a major global health issue, ranking as the fourth most common cancer in women worldwide. Depending on stage, histology, and patient factors, the standard management of cervical cancer is a combination of treatment approaches, including (fertility- or non-fertility-sparing) surgery, radiotherapy, platinum-based chemotherapy, and novel systemic therapies such as bevacizumab, immune checkpoint inhibitors, and antibody-drug conjugates. While ambitious global initiatives seek to eliminate cervical cancer as a public health problem, the management of cervical cancer continues to evolve with major advances in imaging modalities, surgical approaches, identification of histopathological risk factors, radiotherapy techniques, and biomarker-driven personalized therapies. In particular, the introduction of immune checkpoint inhibitors has dramatically altered the treatment of cervical cancer, leading to significant survival benefits in both locally advanced and metastatic/recurrent settings. As the landscape of cervical cancer therapies continues to evolve, the aim of the present review is to provide a comprehensive discussion of the current state and the latest practice-changing updates in cervical cancer.

Dong B, Zhou SF. Efficacy and safety of chemotherapy as monotherapy in patients with recurrent intermediate/high-risk factors following radical hysterectomy for stage IB-IIA cervical cancer: a single-center retrospective analysis. BMC Womens Health 2024; 24:297. [PMID: 38762459 PMCID: PMC11102237 DOI: 10.1186/s12905-024-03135-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2023] [Accepted: 05/07/2024] [Indexed: 05/20/2024] Open
Abstract
OBJECTIVE The aim of this study is to explore the efficacy and safety of chemotherapy (CT) as a monotherapy in patients with recurrent intermediate/high-risk factors following radical hysterectomy for stage IB-IIA cervical cancer. METHODS A retrospective analysis was conducted on the medical records of patients diagnosed with stage IB-IIA cervical cancer who underwent radical hysterectomy at the People's Hospital of Suzhou High-tech District between 2010 and 2020. A total of 66 patients with intermediate or high-risk factors for recurrence were treated exclusively with CT. This cohort included 42 patients in the intermediate-risk group and 24 in the high-risk group. Treatment protocols consisted of 4-6 cycles of paclitaxel and cisplatin drugs for the intermediate-risk group, and 6 cycles for the high-risk group. The relapse-free survival (RFS), recurrence rates, and common CT-related adverse reactions, including bone marrow suppression, nausea and vomiting, and diarrhea, were assessed for both groups. RESULTS (1) The cumulative 3-year RFS rates for the intermediate-risk and high-risk groups were 97.3% (36/37) and 82.4% (14/17), respectively, with cumulative 5-year RFS rates of 97.1% (34/35) and 82.4% (14/17), respectively. The Log rank test revealed no significant difference between the two groups (P > 0.05), (χ² = 2.718, P = 0.099). The 5-year recurrence rates in the intermediate-risk and high-risk groups were 2.38% (1/42) and 12.50% (3/24), respectively. (2) The incidence of grade III bone marrow suppression in the intermediate-risk and high-risk groups was 21.19% (11/42) and 25.00% (6/24), respectively, while the incidence of grade IV bone marrow suppression was 11.90% (5/42) and 8.33% (2/24), respectively. There was no statistically significant difference in bone marrow suppression grades between the two groups (P > 0.05). CONCLUSION CT with paclitaxel and cisplatin, administered as monotherapy post-radical hysterectomy for stage IB-IIA cervical cancer, demonstrates satisfactory survival benefits with an acceptable safety profile. Moreover, no significant differences were observed in prognosis or adverse reactions between the different risk groups treated solely with CT.

Abstract
The cathepsin S (CTSS) gene encodes a lysine cysteine protease and serves an important role in the development of autoimmune diseases, inflammation and nervous system diseases. Furthermore, CTSS is implicated in tumor invasion and metastasis by the induction of tumor angiogenesis and the degradation of the tumor extracellular matrix. Nevertheless, the precise impact of CTSS on predicting pan-cancer prognosis and its influence on the tumor microenvironment and immune infiltration in human cancers remains unknown. This present study employed a comprehensive array of bioinformatic methods to evaluate the expression of CTSS and its associations with prognosis, clinicopathological characteristics, tumor microenvironment, tumor immune infiltration, tumor mutational burden and microsatellite instability across numerous cancer types. The current study demonstrated abnormal expression and distinct genomic alteration profiles of CTSS in many of the cancers tested. Furthermore, CTSS expression exhibited close associations with the prognosis of numerous cancers. High CTSS expression was significantly associated with better overall survival and disease-specific survival in bladder urothelial carcinoma (BLCA) and skin cutaneous melanoma (SKCM) but worse outcomes in brain lower grade glioma (LGG) and uveal melanoma (UVM). Moreover, CTSS demonstrated significant correlations with tumor mutational burden and microsatellite instability in 8 and 12 cancer types respectively, as well as different responses in immunotherapy sub-cohorts, especially in melanoma and bladder cancers. CTSS expression showed a positive correlation with stromal and immune cell scores in the four aforementioned cancers. Moreover, CTSS expression was correlated with the number of infiltrating CD8+ T cells, CD4+ T cells and macrophages. Conversely, CTSS was negatively associated with resting Mast cells, resting NK cells and resting memory CD4+ T cell infiltration in BLCA, SKCM and kidney renal clear cell carcinoma (KIRC). Furthermore, CTSS expression was correlated with immune-related gene expression, notably PDCD1, LAG3, PDCD1 and TIGIT in BLCA, KIRC, SKCM, LGG and UVM. Functional enrichment analysis suggested that CTSS could drive a dynamic adjustment of biological functions and pathways in BLCA, SKCM, LGG and UVM, including immune response regulating signaling pathways, regulation of lymphocyte activation and T cell receptor singling pathways. The current study suggested that CTSS could be an essential biomarker for prognosis and immune infiltration features in multiple cancers.

Diagnostic accuracy of sentinel lymph node frozen section analysis in patients with early-stage cervical cancer: A systematic review and meta-analysis. Gynecol Oncol 2023; 177:157-164. [PMID: 37703622 DOI: 10.1016/j.ygyno.2023.08.019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 08/28/2023] [Accepted: 08/30/2023] [Indexed: 09/15/2023]
Abstract
OBJECTIVE To assess the diagnostic accuracy of intraoperative SLN frozen section analysis compared with ultrastaging in patients with early-stage cervical cancer. METHODS A systematic literature review was conducted following the PRISMA checklist. MEDLINE (via Ovid), Embase, and the Cochrane Central Register of Controlled Trials were searched from inception until February 2023. The inclusion criteria were patients with early-stage cervical cancer (2018 FIGO stage I-II), consisting of the histological subtype squamous cell carcinoma, adenocarcinoma, or adenosquamous carcinoma (≥90% of the patients in each study), who underwent SLN detection (with any tracer) and intraoperative frozen section followed by SLN ultrastaging. Randomized controlled trials, prospective and retrospective observational studies were considered. The detection rates and measures of diagnostic accuracy were pooled using a random effects univariate model. A preplanned subgroup meta-analysis was conducted, with isolated tumor cells excluded as positive lymph nodes. The review was registered in PROSPERO (CRD42023397147). RESULTS The search identified 190 articles, with 153 studies considered potentially eligible after removing duplicates. Fourteen studies met the selection criteria, including a total of 1720 patients. Seven studies were retrospective, and the other seven were prospective. Frozen section analysis detected 159 of 292 (54.5%) patients with lymph node metastases. In 281 patients the type of volume metastasis was reported: 1 of 41 (2.4%) patients had isolated tumor cells, 21 of 78 (26.9%) patients had micrometastases, and 133 of 162 (82.1%) patients had macrometastases. The pooled sensitivity of intraoperative SLN frozen section analysis was 65% (95% CI, 51-77%) for macrometastases, micrometastases, and isolated tumor cells. When we excluded patients with isolated tumor cells, the pooled sensitivity increased to 72% (95% CI, 60-82%). CONCLUSION SLN frozen section detects 65% of lymph node metastases compared with SLN ultrastaging and may prevent unnecessary radical surgery in some patients with early-stage cervical cancer.

Abstract
Objective For early-stage cervical cancer patients experiencing radical surgery, postoperative radiotherapy was recommended for patients with a combination of intermediate-risk factors. However, there was no consensus on whether to administer concurrent chemotherapy. The aim of the study was to confirm the clinical value of the controlling nutritional status (CONUT) score in guiding the use of concurrent chemotherapy during postoperative radiotherapy. Methods A total of 969 patients with FIGO stage IB-IIA cervical cancer were retrospectively analyzed. Kaplan-Meier survival analysis was performed to compare disease-free survival (DFS) and cancer-specific survival (CSS) rates between different group. A Cox proportional hazards regression test was used to conduct multivariate analyses. Results For the patients in the high CONUT group (≥3), the addition of concurrent chemotherapy had better 5-year DFS (91.2 % vs. 72.8 %, P = 0.005) and CSS (93.8 % vs. 77.4 %, P = 0.013) than those without it. Meanwhile, the patients with concurrent chemotherapy had less rate of locoregional recurrence (8.5 % vs 16.7 %, P = 0.034) and distant metastases (11.7 % vs 30.4 %, P = 0.015). The multivariate analysis showed that concurrent chemotherapy was detected to be a factor significantly associated with DFS (P = 0.011), local control (P = 0.041), distant metastasis (P = 0.005) and CSS (P = 0.023). For the patients in low CONUT group (<3), there was no difference in prognosis between patients. Conclusion Pretreatment CONUT score may be a predictive factor for the use of concurrent chemotherapy in early-stage cervical cancer with intermediate-risk factors during postoperative radiotherapy, and it can be helpful to determine the adjuvant treatment scheme.

Abstract
Background Radical hysterectomy with pelvic lymph node assessment is the standard of treatment in early cervical cancer. Adjuvant radiotherapy or chemoradiotherapy are offered to patients with risk factors for recurrence. The objective of this study was to compare the incidence of severe (> G3) early or late morbidity related to treatment in patients with cervical cancer undergoing radical surgery with/without adjuvant treatment in a Latin American center. Materials and methods Retrospective cohort study of patients diagnosed with cervical cancer stage IA1 to IB1. Complications were evaluated according to Common Terminology Criteria for Adverse Events (CTCAE) version 4.0. The cumulative incidence of severe morbidity was estimated. Risk ratios (RR) were calculated to determine the factors associated with morbidity. Results 239 patients were included. 133 (55.6%) received only radical surgical management and 106 (44.4%) adjuvant treatment. The incidence of early morbidity was 18.8% [95% confidence interval (CI): 12.6% to 26.5%] in the group without adjuvant treatment versus 21.7% (95% CI: 14.3% to 30.8%) in the adjuvant treatment group (p = 0.58). Late morbidity was 3% (95% CI: 1% to 7.5%) and 8.5% (95% CI: 4% to 15.5%), respectively (p = 0.063). No statistically significant differences regarding grade ≥ 3 morbidity between the groups was found (2.3% vs. 5.7%, p = 0.289). Complications during surgery is the only factor associated with postoperative morbidity related to treatment (RR = 4.1) (95% CI: 3% to 5.7%). Conclusion In our study, the addition of adjuvant treatment for early cervical cancer patients who underwent radical surgery did not increase the incidence of severe early or late morbidity.

Abstract
PURPOSE The APROVE study is a prospective one-arm phase-2 study investigating the safety and treatment tolerability of postoperative proton beam therapy in women with uterine cervical or endometrial cancer. In this analysis, we report the primary study endpoint of safety and treatment tolerability as well as toxicity rates and progression-free survival (PFS). METHODS AND MATERIALS 25 patients were treated with postoperative proton beam therapy with a total dose of 45 to 50.4 Gy (RBE) in 5 to 6 × 1.8 Gy (RBE) fractions weekly using active raster-scanning intensity modulated proton beam therapy (IMPT). Sequential or simultaneous platinum-based chemotherapy was administered if indicated. The primary endpoint was defined as the lack of any acute ≥grade 3 gastrointestinal (GI) or urogenital (GU) toxicity according to the Common Terminology Criteria for Adverse Events v 4.0 or premature treatment abortion. Secondary endpoints were clinical symptoms and toxicity, quality of life, and PFS. RESULTS All patients completed IMPT according to the protocol, with a median treatment duration of 43 days (range, 33 to 51 days). No patient developed gastrointestinal or genitourinary toxicity ≥grade 3, and the treatment tolerability rate was 100%. Therefore, the null hypothesis H0: Tolerability Rate ≤80% could be rejected in favor of the alternative hypothesis H1: Tolerability rate >80% using an exact binomial test with a one-sided significance level of α = 10% (one-sided P value P = .0059). The median follow-up time after the end of IMPT was 25.1 months (range, 20.2 to 50.3 months). 18 of 25 (75%) patients completed the study follow-up of 24 months. 7 patients had progressive disease. Kaplan-Meier-estimated mean PFS was 39.9 months (95% confidence interval: 33.37 to 46.5 months). CONCLUSIONS Postoperative IMPT is a safe treatment option for cervical and endometrial cancer patients, with only low-grade acute and late toxicities. Larger randomized trials are necessary to further assess the potential of IMPT and improve patient selection.

Health-related quality of life and patient-reported symptoms after postoperative proton beam radiotherapy of cervical and endometrial cancer: 2-year results of the prospective phase II APROVE-trial. Radiat Oncol 2023; 18:5. [PMID: 36624483 PMCID: PMC9827629 DOI: 10.1186/s13014-023-02198-4] [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: 08/17/2022] [Accepted: 01/02/2023] [Indexed: 01/11/2023] Open
Abstract
INTRODUCTION The APROVE-trial investigated the tolerability of postoperative proton beam therapy in women with cervical or endometrial cancer. The present analysis evaluated the secondary endpoints of health-related quality of life (HRQOL) and patient-reported symptoms. METHODS 25 patients were included in this prospective phase-II-trial and treated with postoperative radiotherapy using protons alone or in combination with chemotherapy. To attain general and gynecologic-specific HRQOL measures, the EORTC-QLQ-C30 questionnaires combined with -QLQ-CX24 for cervical and -QLQ-EN24 for endometrial cancer were assessed at baseline, at the end of RT and up to 2 years after radiotherapy. The results were compared to an age-matched norm reference population. Symptoms were assessed using Common Terminology Criteria for Adverse Events (CTCAE) and institutional patient-reported symptoms grading. RESULTS Scores regarding global health status were markedly impaired at baseline (mean: 58.0 ± 20.1) compared to reference population data, but significantly (p = 0.036) improved and evened out to comparable norm values 2 years after proton therapy (mean: 69.9 ± 19.3). Treatment caused acute and long-term worsening of pain (p = 0.048) and gastrointestinal symptoms (p = 0.016) for women with endometrial cancer, but no higher-grade CTCAE ≥ 3° toxicity was observed. Dosimetric evaluation of rectum, sigmoid, large and small bowel showed no correlation with the reported gastrointestinal symptoms. After 2 years, fatigue had significantly improved (p = 0.030), whereas patients with cervical cancer experienced more often lymphedema (p = 0.017). Scores for endometrial cancer pertaining to sexual activity (p = 0.048) and body image (p = 0.022) had improved post treatment; in the latter this effect persisted after 2 years. CONCLUSION Proton beam therapy in the adjuvant setting was well tolerated with only low-grade side effects concerning gastrointestinal symptoms, lymphedema and pain. Overall quality of life was impaired at baseline, but patients were able to recover to values comparable to norm population 2 years after proton therapy. Larger studies are needed to confirm whether the benefit of proton therapy translates into a clinical effect. Sexual dysfunction remains an important issue. TRIAL REGISTRATION The trial was registered at https://clinicaltrials.gov (ClinicalTrials.gov Identifier: NCT03184350, 09th June 2017).

[PMID: 36586018 DOI: 10.1007/s12032-022-01890-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/09/2022] [Accepted: 11/08/2022] [Indexed: 01/01/2023]
Abstract
Dinaciclib is a selective cyclin-dependent kinase inhibitor, but its radiosensitizing effect remains unclear. The aim of this study is to investigate the radiosensitizing effect of Dinaciclib on cervical cancer cells. Two cervical cancer cell lines, Hela and Siha, were selected, and the IC50 was determined by CCK8. The radiosensitizing effect of Dinaciclib was verified by plate cloning assay, and the G2/M phase arrest and apoptosis of IR cells were verified by flow cytometry. Immunofluorescence assay was used to verify the formation of γH2AX foci following DNA damage. Western blot was performed to detect cell cycle, apoptosis, autophagy, and DNA damage-related pathways. Dinaciclib increased the cell sensitivity to IR. IR induced G2/M phase arrest and apoptosis, and Dinaciclib enhanced this effect. Further, Dinaciclib delayed DNA repair, including non-homologous end joining repair and homologous recombination repair, and reduced the expression of DNA repair proteins Ku80 (SiHa cells), Ku70, and RAD51, as well as the expression of apoptotic marker Bcl-2. The expression of autophagy marker Beclin1 induced tumor cell death and increased the formation of DNA damage marker γH2AX foci. Dinaciclib improves the sensitivity of cervical cancer cells to IR by inducing cell cycle arrest, delaying DNA repair, and increasing apoptosis. However, further research is needed to unravel the complexity of DNA repair pathways.

Abstract
Cervical cancer is the fourth most common cancer in women worldwide. The preferred treatment for early stage cervical cancer is radical hysterectomy with pelvic lymph node assessment, and adjuvant therapy is suggested according to histopathological risk factors. A landmark study was published in 1999 that established 'intermediate risk' criteria for relapse, showing a benefit in recurrence free rate in patients that received pelvic radiotherapy. Furthermore, in the presence of parametrial, nodal, or vaginal margin involvement, another key study found that the addition of concurrent cisplatin based chemotherapy to radiation therapy improved progression free and overall survival for 'high risk' early cervical cancer. With the advancement in treatment modalities in surgery and radiotherapy, and the improved identification of prognostic histopathological factors, several authors have reconsidered the role of adjuvant therapy after radical hysterectomy in the presence of intermediate risk criteria. Here we review the literature on the evolution of adjuvant therapy for intermediate risk factors.

Patterns of relapse after adjuvant (chemo)radiation for cervical cancer in a phase III clinical trial (PARCER): an evaluation of updated NRG Oncology /RTOG target delineation guidelines. Int J Radiat Oncol Biol Phys 2022; 113:369-378. [PMID: 35157993 DOI: 10.1016/j.ijrobp.2022.02.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2021] [Revised: 01/31/2022] [Accepted: 02/03/2022] [Indexed: 12/31/2022]
Abstract
AIM NRG Oncology/RTOG recently published updated contouring guidelines for intensity modulated radiotherapy in postoperative treatment for endometrial and cervical cancer. The present study was designed to evaluate the implications of newly published guidelines. METHODS Patients (n = 300) recruited in Phase III RCT of adjuvant (chemo)RT for cervical cancer (NCT01279135) were included for understanding patterns of relapse. For those with pelvic relapse, RT structure sets, treatment plans and diagnostic images at relapse were imported on the treatment planning system. Rigid registration was performed with treatment planning images that contained the delineated PTV and radiation dose information. Gross tumor volume at time of relapse was delineated on the diagnostic scans and superimposed on the radiotherapy treatment scans. The site of pelvic relapse was categorized as "within field of old RTOG/PARCER target delineation guidelines" or/and "within field of new NRG/RTOG guidelines" and proportions of recurrences contained within the two guidelines were compared. p-value of <0.05 was considered statistically significant. Additionally, IMRT treatment plans were generated based on the new guidelines for a limited set of patients to see if these new guidelines increased the organ at risk doses. RESULTS Most common form of relapse was distant metastasis (15%). Pelvic relapse rate in our study was 8%. Overall 9/19 relapses were encompassed in the old RTOG/PARCER contouring guidelines while 12/19 were encompassed within the new RTOG 2021 contouring guidelines. This corresponded to a further 1% reduction in local relapses (p 0.007). Dose to rectum was marginally increased with the new contouring, with no difference in other organs at risk. Salvage treatment was offered in 25/60 patients who relapsed. In patients who received local treatment after relapse had a mean survival after relapse of 27.2 months compared to 8 months who received supportive care alone. CONCLUSION Our study supports the use of newly published NRG/RTOG contouring guidelines in patients with cervical cancer who have undergone hysterectomy. Further data is needed to ascertain if anterior extension of the CTV is needed as in PARCER trial.

Preoperative high-dose-rate brachytherapy for high-risk early-stage cervical cancer: Long-term clinical outcome analysis. Brachytherapy 2022; 21:273-282. [PMID: 35094933 DOI: 10.1016/j.brachy.2021.11.007] [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: 09/09/2021] [Revised: 11/16/2021] [Accepted: 11/24/2021] [Indexed: 11/19/2022]
Abstract
OBJECTIVE To report long-term oncological and toxicity outcomes after high-dose-rate brachytherapy (HDB) followed by oncologic surgery for patients with early-stage cervical cancer. METHODS AND MATERIALS From 2005 to 2019, all patients treated with preoperative HDB at Antoine Lacassagne Cancer Center for early-stage (IB1-IB2-IIA - FIGO 2018) cervical cancer with local relapse risk factors were included. HDB was performed followed by hysterectomy. Oncological and toxicity outcomes were evaluated prospectively. RESULTS We identified 61 patients, with a median follow-up of 84 months. Posthysterectomy complete pathological response was observed in 46 patients (75.4%). Six patients (9.8%) experienced recurrence, including 4 local relapses (6.6%), and 2 deaths (3.3%) due to cervical cancer. Five-year local, nodal and metastatic relapse-free survivals were 94% (95% CI 87-100%), 96% (95% CI 90-100%) and 93% (95% CI 86-100%) respectively. Five-year overall survival was 98% (95% CI 95-100%). No grade ≥ 3 acute toxicity was observed, and 3 patients (4.9%) experienced grade 2 acute toxicity. One patient presented grade 4 late digestive toxicity, and 6 patients had grade 2 late toxicity. Only 1 patient still had grade 2 toxicity, after 9 years follow-up. CONCLUSIONS To our knowledge, we are reporting the longest follow-up of a preoperative HDB cohort. With similar oncological outcomes and less morbidity compared to primary surgery treatment followed more or less by adjuvant radiotherapy, HDB followed by hysterectomy could be a promising therapeutic option for early-stage cervical cancers with poor prognostic factors.

Abstract
Introduction: In the adjuvant setting for cervical cancer, classical
risk factors for postoperative radiochemotherapy have been established. However,
data on laboratory changes during therapy and the prognostic value of
serological markers are limited and further knowledge is needed to optimize the
toxic trimodal regimen. Methods: We retrospectively identified 69
women who underwent weekly postoperative radiochemotherapy with
40 mg/m2 of cisplatin for cervical cancer between 2010 and 2021
at a single center. Laboratory parameters were recorded before, at each cycle
and after radiochemotherapy. Kaplan-Meier and log-rank analyses were used to
calculate and compare survival, groups were compared using the Mann–Whitney
U, χ2, and variance tests. Results:
With a median follow-up of 17.7 months, the 1- and 5-year local control rates
were 94.0% and 73.7%, respectively, with significantly better rates for more
chemotherapy cycles and negative resection margins. Only 68.1% of patients
completed all cycles. The most common reasons for early discontinuation were
persistent asymptomatic leukopenia in women aged ≤ 50 years, and limiting
infections in women aged > 50 years. Leukopenia was more likely to occur
after the third cycle. Significantly worse survival was observed for
post-radiochemotherapy elevated C-reactive-protein and lactate dehydrogenase
levels, low pre-radiochemotherapy nutritional index, and raised
C-reactive-protein-levels; the latter were also predictable for local control.
The Glasgow prognostic score did not reliably predict survival.
Conclusion: Incomplete application of simultaneous chemotherapy
leads to inferior local control, and age-dependent limiting factors should be
identified at an early stage. In addition to classical risk factors, serological
markers (C-reactive-protein, lactate dehydrogenase, nutritional index) show
prognostic significance.
