The purpose of this phase II trial was to assess the efficacy and toxicity of paclitaxel and nedaplatin (TN) as the initial postoperative adjuvant chemotherapy for uterine cervical cancer with lymph node metastases (LNM). Patients with FIGO stage IB1-IIA2 squamous cell carcinoma of the uterine cervix were enrolled. Histological confirmation of LNM was mandatory. Intravenous paclitaxel at 175 mg/m 2 and nedaplatin at 80 mg/m 2 were administered every 28-day cycle, of which there were 5 cycles after radical hysterectomy. Sixty-two patients were enrolled in the study from November 2011 to July 2015. Their median age was 48.5 years (range 28-64). The median tumor diameter was 37 mm (5-64). Overall, 30 patients (48.4%) had 1 metastatic lymph node, 11 (17.7%) had 2, 3 (4.8%) had 3, 5 (8.1%) had 4, and 13 (21.0%) had 5 or more. With a median follow-up of 45.7 months (range 23.4-69.5), the 2-year relapse-free survival and 2-year overall survival rates were 79.0% (90% CI, 69.0%-86.2%) and 93.5% (95% CI, 83.7%-97.5%), respectively. Almost all adverse events were relatively mild. Grade 3-4 adverse events (NCI-CTC ver. 4.0) that occurred in 5% or more of patients were neutropenia (60.7%) and infection (6.6%). The proportion of patients who completed 5 cycles of treatment was 90.3%. Postoperative adjuvant chemotherapy with TN for cervical cancer with LNM was demonstrated to be an effective and feasible treatment. A phase III trial is warranted to compare this with concurrent chemoradiotherapy., (© 2018 The Authors.

Background: We examined the efficacy and safety of neoadjuvant chemotherapy (NAC) with the CPT-11 + CDDP regimen in combination with radical hysterectomy., Subjects and Methods: The subjects were 42 patients with stages IB2 to IIIB squamous cell carcinoma of the uterine cervix with a bulky mass. CDDP at 70 mg/m 2 was intravenously administered on day 1 and CPT-11 at 70 mg/m 2 was intravenously administered on days 1 and 8 of a 21-day cycle. In principle, two cycles were administered followed by radical hysterectomy. We examined antitumor efficacy, adverse events, completion rate of radical hysterectomy, operative time, surgical blood loss, progression-free survival (PFS), and overall survival (OS)., Results: The antitumor effect was complete response in 7 patients, partial response in 28, stable disease in 6, and progressive disease in 1; the response rate was 83.3 % (95 % confidence interval, 68.6-93.0). Grade 3 or more severe neutropenia, anemia, and platelet count decreases were noted in 23 (54.8 %), 4 (9.5 %), and 1 (2.4 %) patient, respectively. Grade 3 nausea occurred in 3 patients (7.1 %), vomiting in 1 (2.4 %), and grade 3 febrile neutropenia in 2 (7.1 %). The completion rate of radical hysterectomy was 88.1 %. The median operative time and surgical blood loss were 260 min (range, 210-334) and 500 ml (range, 393-898), respectively. The 5-year PFS rate was 67.2 %, and the 5-year OS rate was 68.0 %. In multivariate analysis, lymph node metastasis before NAC [hazard ratio (HR), 34.88] and non-response to NAC (HR 30.58) were significant prognostic factors., Conclusion: NAC with the CDDP/CPT-11 regimen achieves a high antitumor efficacy with moderate adverse reactions, allowing safe radical hysterectomy, and is thus considered to be a useful therapeutic method that can improve prognosis., Competing Interests: None of the authors of this manuscript has any conflicts of interest to declare.

Objective: The aim of this study was to compare the efficacy of nedaplatin-based concurrent chemoradiotherapy (CCRT) with that of cisplatin-based CCRT in patients with cervical cancer., Methods: The medical records of patients with cervical cancer who had undergone CCRT between 2003 and 2007 were retrospectively reviewed. Of these, 129 patients were treated postoperatively with CCRT (n = 52) or primary CCRT (n = 77). A total of 29 patients were treated with nedaplatin-based postoperative CCRT and 23 patients were treated with cisplatin-based postoperative CCRT. A total of 28 patients were treated with nedaplatin-based postoperative CCRT, and 49 patients were treated with cisplatin-based postoperative CCRT. Progression-free survival (PFS) and overall survival (OS) were compared between the treatment groups., Results: With postoperative CCRT, there were no significant differences in recurrence rate (P = 1.0000), PFS (log-rank: P = 0.8503), and OS (log-rank: P = 0.8926) between the two treatment groups. With primary CCRT, there were no significant differences in PFS (log-rank: P = 0.7845) and OS (log-rank: P = 0.3659). The frequency of acute toxicity was not significantly different between the cisplatin-based postoperative CCRT group and the nedaplatin-based postoperative CCRT group., Conclusions: Nedaplatin-based postoperative CCRT is an effective and well-tolerated regimen for both early-stage and advanced-stage cervical cancer patients.

Background: Neoadjuvant chemotherapy (NAC) is not yet widely recommended for the treatment of stage I/II cervical cancer. However, it may be possible to achieve a favorable outcome by selecting appropriate patients. In the present study, prognostic factors were retrospectively investigated to obtain data for devising individualized NAC., Patients and Methods: The subjects were 33 patients with bulky stage Ib2-IIb squamous cell carcinoma (SCC) of the uterine cervix who gave consent and were scheduled to undergo radical hysterectomy. The patients intravenously received irinotecan 70 mg/m(2) on days 1 and 8 and cisplatin 70 mg/m(2) on day 1 of a 21-day course, and two courses were performed in principle. The potential prognostic factors investigated were age, performance status (PS), clinical stage, lymph node metastasis and tumor size before NAC, SCC antigen value, anti-tumor response, histological effect of NAC, lymph node metastasis in resected specimens, and postoperative adjuvant therapy after NAC. The impacts of these factors on overall survival (OS) were calculated with the Cox regression model., Results: According to the univariate analysis, lymph node metastasis before NAC, SCC antigen value after NAC, anti-tumor response, and histological effect of NAC significantly influenced OS. These factors were tested in a multivariate model, and significant prognostic factors were lymph node metastasis before NAC (hazard ratio 0.116, P = 0.027) and anti-tumor response (hazard ratio 0.025, P = 0.003)., Conclusion: The presence or absence of lymph node metastasis by computed tomography imaging was the only significant prognostic factor identified during the pre-NAC period.

Purpose: There are no reports on the use of neoadjuvant chemotherapy (NAC) in non-squamous cell cervical carcinoma. We examined the effectiveness and safety of paclitaxel/carboplatin (TC) and docetaxel/carboplatin (DC)., Methods: Stage Ib2 to IIb disease was present in 23 patients scheduled for radical hysterectomy. We administered 1-3 courses of either the TC or the DC regimen. Anti-tumor effects were found superior by Response Evaluation Criteria in Solid Tumors. Safety was assessed with National Cancer Institute Common Terminology Criteria for Adverse Events., Results: Median age was 50 years (range 32-63 years), with stage Ib2 in 6 cases (26.1%) and IIb in 17 cases (73.9%). Complete response was achieved in 5 cases (21.7%), partial response in 13 (56.5%), stable disease in 5 (21.7%); the response rate was 78.3%, and surgery completion rate was 78.3%. Leukopenia or neutropenia ≥grade 3 was seen in 12 (52.2%) and 21 (91.3%) cases, respectively, with grade 3 febrile neutropenia in 2 cases (8.7%) and no anemia or thrombocytopenia ≥grade 3. Median progression-free survival was 26 months (95% Cl, 13.5-38.5 months); median overall survival was 35 months (95% Cl, 20.9-49.1 months)., Conclusion: NAC for non-squamous cell cervical carcinoma showed potent anti-tumor effects and manageable adverse events.

Objective: We assessed the antitumor response and safety of neoadjuvant chemotherapy (NAC) using cisplatin (CDDP) and irinotecan(CPT-11)given every three weeks for locally advanced cervical cancer with a bulky mass., Subjects and Methods: Nineteen patients with cervical squamous cell cancer in FIGO stage of Ib2 to IIb were enrolled in this study. The FIGO stages were Ib2 in 5 patients, IIa in 2 patients, and IIb in 12 patients. One course of the chemotherapy regimen consisted of intravenous administrations of CDDP at a dose of 70 mg/m 2(day 1)and CPT-11 at 70 mg/m 2 (days 1 and 8) for 21 days, and two courses were administered. This chemotherapy was assessed for antitumor response, adverse events, complete surgical removal rate, progression-free survival time, and overall survival time. RECIST and NCI-CTCAE were used to determine antitumor response and adverse events, respectively., Results: The results of assessment of the antitumor response showed CR in 3 patients(15. 8%), PR in 14(73. 7%), SD in 1 (5. 3%), and PD in 1(5. 3%). Neutropenia of grade 3 or higher occurred in 13 patients(68. 4%). Anemia occurred in 2 patients(10. 5%), and thrombocytopenia in 1 patient(5. 3%). Nausea and vomiting were observed in 2 patients(10. 5%). All patients underwent a chemotherapy regimen consisting of two courses, and the rate of complete surgical removal was 94. 7%. The median observation period was 27 months; the progression-free survival time was 18 months, and survival time was 27 months., Conclusion: Adverse drug reactions to NAC with the CDDP/CPT-11 combination administered every three weeks were controllable. The antitumor response rate for this chemotherapy was high. These assessment results indicate that NAC with a CDDP/CPT-11 combination was useful for local advanced cervical cancer.

A case of granulocyte colony-stimulating factor (G-CSF)-producing small-cell carcinoma of the uterine cervix is described. In a 70-yr-old woman, clusters of small cells with hyperchromatic nuclei at a high nuclear/cytoplasmic ratio were detected cytologically in the cervix. These clusters were diagnosed as a small-cell neuroendocrine carcinoma by the concomitant use of Grimelius staining and immunohistochemical staining, in addition to electron microscopic observation. This patient showed a significant increase in peripheral leukocytes, despite the absence of infectious signs. Immunohistochemical findings, together with a high blood G-CSF level, suggested the production of G-CSF from the tumor. Consistent with the knowledge that both small-cell carcinoma and G-CSF-producing tumors have a poor prognoses, the patient had no or partial response to therapies performed, and died from the cancer 11 mo after it was diagnosed. This case strongly indicates the need for early diagnosis of this type of tumor, based on cytological features., (Copyright 2000 Wiley-Liss, Inc.)
