Aims: To investigate the oncologic and obstetric outcomes of radical trachelectomy (RT) in patients with early-stage cervical cancer and to evaluate the potential role of fertility-preserving treatments in improving pregnancy outcomes while oncologic status is stable., Methods: In this single-institution study, we analyzed the oncologic and obstetric outcomes of 67 patients with early-stage cervical cancer who underwent RT at Nagoya University Hospital., Results: The cancer recurrence rate (6.0%) and the mortality rate (1.5%) were comparable with those of previous studies. Of the 46 patients who attempted to conceive after RT, 19 (41.3%) became pregnant, and 16 gave birth. Of these 37.5% delivered at term, and delivery at less than 28 weeks of gestation occurred in 31.3% of pregnancies., Conclusions: RT is a viable treatment option for selected patients with early-stage cervical cancer. However, the use of less invasive techniques, such as conization/simple trachelectomy and pelvic lymph node dissection, may improve pregnancy outcomes while oncologic status is stable., (© 2023 Japan Society of Obstetrics and Gynecology.)

Systemic sclerosis, an autoimmune disease characterized by fibrosis and vasculopathy of the skin and other multiple organs has been associated with an increased risk of malignancy. We present the case of a 74-year-old woman who had diffused cutaneous systemic sclerosis and uterine cervical cancer. The patient was initially diagnosed with stage IIB squamous cell carcinoma and concurrent chemoradiotherapy was planned. However, cisplatin could not be administered due to acute renal failure, so the patient was treated solely with radiotherapy. However, complications of systemic sclerosis progressed rapidly, and the patient died 63 days later from pulmonary edema. An autopsy later revealed that uterine cervix had primary signet ring cell carcinoma. We suspected that this patient had a combination of signet ring cell carcinoma and squamous cell carcinoma, with squamous cell carcinoma disappearing after radiotherapy. This case highlighted the importance of systemic management for cancers associated with systemic sclerosis., (© 2023 Japan Society of Obstetrics and Gynecology.)

Magnetic resonance imaging (MRI) is used for pretreatment staging in cervical cancer. In the present study, we used pretreatment images to categorize operative cases into two groups and evaluated their prognosis. A total of 53 cervical cancer patients with squamous cell carcinoma who underwent radical hysterectomy were included in this study. Based on MRI, the patients were classified into two groups, namely clear and unclear tumor border. For each patient, the following characteristics were evaluated: overall survival; recurrence-free survival; lymph node metastasis; lymphovascular space invasion; and pathological findings, including immunohistochemical analysis of vimentin. The clear and unclear tumor border groups included 40 and 13 patients, respectively. Compared with the clear tumor border group, the unclear tumor border group was associated with higher incidence rates of recurrence (3/40 vs. 3/13, respectively), lymphovascular space invasion (24/40 vs. 13/13, respectively), lymph node metastasis (6/40 vs. 10/13, respectively), and positivity for vimentin (18/40 vs. 10/13, respectively). Despite the absence of significant difference in recurrence-free survival (p = 0.0847), the unclear tumor border group had a significantly poorer overall survival versus the clear tumor border group (p = 0.0062). According to MRI findings, an unclear tumor border in patients with squamous cell cervical cancer is linked to poorer prognosis, lymph node metastasis, and distant recurrence of metastasis., (© 2023.

Radical surgery after cervical conization is a common approach for the treatment of cervical cancer. In some cases, disease progression is observed after positive margins at conization, but the effect of conization on disease progression remains unclear. Thus, the aim of this study was to investigate the clinical outcomes of positive margins at conization in cervical cancer. A total of 101 patients who underwent cervical conization before radical hysterectomy and pelvic lymph node dissection were considered eligible by reviewing medical records. The association between the positive margins and patient outcomes, including subsequent lymph node metastasis, was evaluated. The rate of lymphovascular space invasion (LVSI) positivity at radical surgery was significantly higher in patients with positive margins (p = 0.017) than in those with negative margins, although there was no significant difference in the rate of pelvic lymph node metastasis (p = 0.155). Moreover, there was no significant difference in the overall survival or progression-free survival between the two groups (p = 0.332 and 0.200, respectively). A positive margin at conization presented no significant prognostic disadvantage; thus, diagnostic conization is one of the most suitable treatment options for early-stage cervical cancer that is difficult to accurately assess., (© 2021.

Background/aim: Heat shock protein 105 (HSP105) is overexpressed in various cancers, but not in normal tissues. We investigated the expression levels of HSP105 in cervical cancer and the efficacy of immunotherapy targeting HSP105., Materials and Methods: Previously, we established human leukocyte antigen-A*02:01 (HLA-A2) restricted HSP105 peptide-specific cytotoxic T lymphocyte (CTL) clones from a colorectal cancer patient vaccinated with an HSP105 peptide. Herein, we evaluated the expression of HSP105 in cervical cancer and cervical intraepithelial neoplasia. Moreover, we tested the effectiveness of an HLA-A2-restricted HSP105 peptide-specific CTL clone against cervical cancer cell lines., Results: HSP105 was expressed in 95% (19/20) of examined cervical cancer tissues. Moreover, the HSP105 peptide-specific CTL clone recognized HSP105- and HLA-A*02:01-positive cervical cancer cell lines and also showed that cytotoxicity against the cervical cancer cell lines depends on HSP105 peptide and HLA class I restricted manners., Conclusion: HSP105 could be an effective target for immunotherapy in patients with cervical cancer., (Copyright © 2021 International Institute of Anticancer Research (Dr. George J.

(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.

Background: This study was conducted to investigate the prognostic significance of sarcopenia in patients with organ metastatic cervical cancer., Methods: Accordingly, the data of 40 patients with organ metastatic cervical cancer treated at our institute from December 2004 to December 2017 were retrospectively analyzed. The correlation between clinicopathological characteristics and survival was then evaluated using univariate and multivariate analyses. Psoas muscle index (PMI), calculated from the psoas muscle area at the L3 vertebral-body level using computed tomography images obtained for pretreatment evaluation, was adopted as an index of sarcopenia., Results: The median follow-up period was 14 months (range, 1-91 months). Kaplan-Meier analysis showed a 3- and 5-year overall survival (OS) rate of 46.1% and 35.8% for all patients, respectively. Receiver operating characteristic curve maximizing the area under the curve showed that the optimal PMI for predicting 1-year survival was 3.72 cm 2 /m 2 . Patients with a PMI > 3.72 cm 2 /m 2 had significantly better OS than those with a PMI ≤ 3.72 cm 2 /m 2 (P = .046). Multivariate analysis revealed that only PMI was significantly associated with OS in patients with organ metastatic cervical cancer. Furthermore, patients with a PMI > 3.72 cm 2 /m 2 who underwent concurrent chemoradiotherapy (CCRT) had a longer OS than those receiving other therapies (P < .001)., Conclusions: High PMI was determined to be a favorable prognostic factor for patients with organ metastatic cervical cancer. Moreover, patients with organ metastatic cervical cancer who have a PMI > 3.72 cm 2 /m 2 may benefit from CCRT as an initial treatment., (© 2020 American Society for Parenteral and Enteral Nutrition.)

Background: The standard treatment for cervical cancer is chemoradiation although some patients showed treatment resistance. The purpose of this study was to investigate the clinical efficacy of surgery after chemoradiation for cervical cancer., Methods: Patients with FIGO stage IB2 to IIB cervical cancer were included in the study between 2005 and 2015. A total of 50 patients who underwent surgery after neoadjuvant chemoradiation and 76 patients who received only chemoradiation were compared. Baseline differences between the two groups were adjusted with inverse probability of treatment weighting method using propensity scores composed of the following independent variables: age, stage, tumor size, lymph node metastasis, and histological subtypes., Results: Median follow-up was 64.8 (range 4.8-143.9) months. After adjustment with inverse probability of treatment weighting, Kaplan-Meier curves showing adjusted progression-free survival and overall survival were significantly longer in the neoadjuvant chemoradiation compared with the chemoradiation-only group (p = 0.027 and p = 0.017, respectively). Moreover, in patients with squamous cell carcinoma, recurrence in previously irradiated field and recurrence both in and out of previously irradiated field were significantly decreased in the neoadjuvant chemoradiation compared with the chemoradiation-only group (3.1% and 18.4%, respectively; OR 0.142, p = 0.001]. Adverse events of surgery after chemoradiation were acceptable, although temporary hydronephrosis was frequently observed (23.1%)., Conclusions: Surgery after chemoradiation reduced pelvic recurrence, and as a result, patients who underwent neoadjuvant chemoradiation showed more favorable survival outcomes compared with those who only underwent chemoradiation.

Background: Ubiquitin-associated protein 2-like (UBAP2L) has been demonstrated to be associated with the progression of multiple types of cancer. However, the function of UBAP2L in uterine cervical cancer remains unclear., Materials and Methods: Between 2005 and 2015, 84 patients who underwent surgery were included in this study. The patients were stratified into two groups on the basis of immunohistochemical staining for UBAP2L, and survival analysis was performed. Moreover, loss-of-function analysis was performed using the cervical cancer cell lines CaSki and SiHa., Results: Based on immunohistochemistry, the overall survival in patients with low UBAP2L expression was significantly longer than that of those with high UBAP2L expression (p=0.045). The in vitro experiment revealed that knockdown of UBAP2L remarkably inhibited cell proliferation in both live cell imaging and the MTS assay., Conclusion: Patients with high UBAP2L expression had unfavorable prognosis and UBAP2L appears to play an important role in proliferation., (Copyright© 2020, International Institute of Anticancer Research (Dr. George J.

Background: In cervical cancer, para-aortic lymph nodes are common sites of metastasis. The purpose of the study was to evaluate the clinical benefits of prophylactic irradiation as postoperative therapy., Methods: A retrospective cohort study was conducted during 2001-2015 at a single institution. Patients with a high risk of para-aortic lymph nodes recurrence were eligible for this study, and we identified patients who had pelvic lymph node metastasis and underwent radical surgery and concurrent chemo-radiotherapy. As a result, 33 and 46 patients were included in the treatment (prophylactic irradiation) and non-treatment groups, respectively. Baseline differences between the two groups were adjusted with the inverse probability of treatment weighting using propensity scores composed of the independent variables including age, stage, tumor size, pathological findings, lymph node status, and pathological subtypes., Results: In the 68-month median follow-up period (range 6-178 months), 25 patients experienced recurrence, and 17 patients were dead. After adjustment with the inverse probability of treatment weighting, the recurrence rates tended to decrease in the treatment group, but there was no significant difference between the two groups [treatment vs. non-treatment, 29.4% and 44.3%, respectively; hazard ratio, 0.593 (95% CI 0.320-1.099); P = 0.097]. However, adjusted para-aortic lymph nodes recurrence rates were not significantly different [treatment vs. non-treatment, 7.8% and 11.4%, respectively; odds ratio, 0.660 (95% CI 0.187-2.322); P = 0.558]. Moreover, Kaplan-Meier curves showing post-recurrence survival revealed no significant difference between the two groups (P = 0.141)., Conclusions: Prophylactic para-aortic lymph nodes irradiation did not reduce the risk of recurrence.

Background: Elderly patients with uterine cervical cancer reportedly have a poorer prognosis than younger patients. Until now, the benefit of concurrent chemoradiotherapy (CCRT) for elderly patients has been considered limited., Methods: We retrospectively analyzed 49 women with cervical cancer aged &gt;70 years primarily treated with radiotherapy (RT) or CCRT in our institute between 2003 and 2014. Treatment compliance, toxicity, and survival benefit were analyzed., Results: A total of 49 patients were identified in this retrospective analysis. Twenty patients with a median age of 75.4 years (range 70-77) were treated with CCRT and 29 patients with a median age of 77.9 years (range 70-89) underwent RT. In the CCRT group, 14 patients (70%) completed CCRT consisting of radiotherapy and 5 courses of cisplatin plus 5-fluorouracil including patients requiring a dose reduction of chemotherapy. The median overall survival (OS) in the CCRT and RT groups was 66.9 and 60.1 months, respectively (p = 0.156). The most common grade 3/4 acute toxicity was hyponatremia (35.0%), followed by neutropenia (15.0%) and diarrhea (10.0%) in the CCRT group, while this was anemia (17.2%) followed by radiation enteritis (10.3%) in the RT group., Conclusions: CCRT was well tolerated in elderly patients with cervical cancer. Careful attention should be paid to the different characteristics of treatment-related toxicities in this group compared with younger patients.
